ELETROLUMINESCENT DIGITAL LIGHTING MIRROR Ξ YOUR

The present invention relates to illuminating mirrors and, more particularly, to an illuminating mirror of eletroluminescent.es diodes and to their method of forming.

Electroluminescent diodes or LEDs (English LEDs) were initially used to constitute indicator lights or indicator lights for electrical and electronic devices and, for a number of years, have provided lighting for signaling devices such as beacons, vehicle headlamps (flasher, positioning lights), or portable lamps or signal lamps. The interesting aspect of the diodes relates to their prolonged duration, illuminating efficiency, robustness, making perennial devices that use such devices and with low maintenance needs.

Recently, the use of LEDs has extended to the field of mirrors, with the purpose of proposing illuminating mirrors. Patent application WO2012028819 discloses in the first embodiment shown in Figure 1 an LED illuminating mirror comprising: a pane with a first main face forming the rear face, and a second main face forming the front face, a region in the case of sandblasting or acidification of the glass, on the periphery of the mirror, along the first longitudinal edge of the glass pane with a width of less than 200 mm, a group of inorganic (or LED) electroluminescent diodes disposed on the side of the back face, along the more peripheral longitudinal edge of the diffusing range.

Each of the diodes has a given emission spectrum in the visible, for example a white light, and with a main emission radius F, said first major radius, substantially parallel to the rear face. The emission cone can be, for example, Lambertian. The beam of each diode is divergent and defined by a half-height half-height of 60 °. The mirror further includes on the side of the rear face a profile which forms a light reflector from the diodes, positioned along the more central edge of the diffuser strip. The reflector profile is metallic, for example, of anodized aluminum, with a thickness of less than or equal to 3mm, and comprises: a main said elongated portion oblique to the rear face, which extends into contact with the rear face, a elongated part, extending the main part opposite the rear face. The reflector profile further includes an elongate lateral portion which extends the flat and substantially normal portion to the rear face and contains the diodes on its printed circuit board or PCB. To hide the end of the main part, the central region of the mirror advances beneath the main part. The mirror is attached to a wall (wall, ceiling, partition wall, etc.) by the side, which forms a structure that surrounds the mirror with an edge on the front face. As an example of the dimensions of the different elements: the surface of the pane is 600x600mm, being an extraclaro glass with 2, Smm of thickness, the distance between the wall and the pane is 28mm, the width of each first illuminating strip is 40mm and the length of each first illuminating strip is 550mm, the width of the central decorative region is approximately 4QQmm, each plate containing diodes is 10mm wide, 550mm long, 1.9mm thick, and the diodes with no optical components , have a height of the order of 2mm, width less than 6mm, with a regular distance between diodes of 18mm, the height, distance between the diodes and the first diffuser patterns, is of the order of 15mm,

the diodes have an individual power of 0.3W (approximately) and a minimum efficiency of 40 lrnúW (10 menesúWatt).

A reflective surrounding structure (rear face side) includes the support piece and the main reflector that surrounds (along with whatever the outline) the elongated pattern or the discoid or square pattern. Or a reflective surrounding structure (rear face side) includes the support part surrounding the injection contour of the frame-shaped pattern and another surrounding reflective structure (rear face side) comprising the main reflector surrounds the other outline of the pattern in form. The reflecting surrounding structure is a monolithic frame or several contiguous or spaced apart pieces less than 5mm, the surrounding reflective structure being affixed to the rear face, and the other possible reflective surrounding structure being a monolithic frame or several contiguous or spaced apart pieces to less than 5mm, the surrounding reflective structure being fixed to the rear face.

Of course, the term reflector is understood as an element that reflects visible light. The first group of diodes (and the complete support piece, preferably) is arranged (preferably below the mirror layer and / or a cover layer), with: a distance ei between the facade pane (preferably with the mirror layer) and each face emitting the first group of diodes greater than or equal to 5mm, preferably greater than or equal to 10mm, a distance ff between the inner face of the bottom reflector and each face emitting the first group of diodes such that the difference in absolute value ei-ef is less than or equal to 20mm, preferably less than or equal to 10mm, and with the elongated pattern (in rectangular strip, in L, U, etc.), a distance Dl between the first longitudinal edge and each emitting surface of the first group of diodes of at least 10mm, preferably at least 12mm and even at least 15mm and preferably of at most 40mm and more preferably of at most 30mm and even of at most 20mm for the pattern the disk or square, a distance D between the edge of the diffuser pattern and each face emitting the first group of diodes of at least 10 mm, preferably at least 12 mm and even at least 15 mm, and preferably of at most 40 mm, and more preferably at a distance Dl between the injection contour of the diffuser pattern and each face emitting the first group 41 of at least 10 mm, preferably of at least 12 mm and even of at least 30 mm, and even of at most 2 Omni for the pattern in the form of a frame, less 15mm and preferably of at most 40mm and more preferably of at most 30mm and even of at most 20mm.

When W1 or W1 is greater than 70 mm, the main reflector has an internal (preferably flat) wall forming an angle of at most 5 ° with the facade pane and preferably of at most 10 ° with the bottom reflector and contains a printed circuit board, said second PCB board, and in front of the support piece (and the first PCB board with a vertical movement tolerance), second PCB board with a second group of electroluminescent diodes, queued, preferably with high emission and including substantially perpendicular to the facade glazing, each of the diodes (identical or similar to those of the first group) having:

preferably a transmitting face perpendicular to the second PCB plate, a given visible, preferably polychromatic, especially white, emission spectrum, in particular similar to or identical with the emission spectrum of the first group, a main light beam F 'forming an angle of no maximum 5 ° with the facade pane (average plane of the pane if it is bulged) and preferably no more than 10 ° with the bottom reflector (or the median plane of the bottom reflector if it is bulged, concave towards the internal space ), a diverging beam defined by a half-height half-angle of at least 40 ° to even 50 ° (angle defined from the radius F 'of the 0 ° angle), (similar or identical to the beam of the first group), the adjacent diode bundles of said second group overlapping the diffuser pattern, in particular a color temperature other than a maximum of 200K of the color temperature of the first group of diodes, in particular an efficiency of the set of diodes on the PCB board of at least 80 lmuW. The second group of diodes (and the main reflector preferably) is arranged (preferably below the mirror layer and / or a cover layer) with: a distance e'i between the facade pane (preferably with the mirror layer) and each emitting face of the second group of diodes greater or equal to 5mm preferably greater than or equal to 10mm, a distance e'f between the inner face of the bottom reflector and each face emitting the second group of diodes such that the difference in value absolute e'i -e'f is less than or equal to 20mm, preferably less than or equal to 10mm, and with the elongated (triangular, L, U, triangular) stripe pattern, the diodes of the second group being at along the second longitudinal edge, with a distance D2 between the second longitudinal edge and each emitting face of the second group of diodes of at least 10 mm, preferably of at least 12 mm and even of at least 15 mm, and preferably of at most 40 mm and m greater preference of a maximum of 30 mm and even of a maximum of 20 mm, for the pattern in the form of a frame the diodes of the second group lie along the other contour distinct from the injection contour, said other injection contour, with a distance D 2 between the other injection contour and each emitting face of the second group of diodes of at least 10 mm, preferably at least 12 mm and even at least 15 mm, and preferably at most 40 mm, and most preferably at most 30 mm, and inclusive of at most 20mm. The invention makes it possible to uniformly and efficiently illuminate various patterns on the back of a mirror and to conceal the lighting system (diode, transformer, etc.) fixed behind the facade glazing: thanks to the choice of the specific background reflector with the reflective layer on the rear face, thanks to the choice of surrounding structure that forms with the light reflector with a light box, to the positioning of the diodes: orientation of F, F ', sufficient separation distance of the diffuser pattern by controlling the distances D1 (if D2), position in front of the diffuser pattern (ei) and the bottom reflector (ef).

In addition, to allow greater freedom for architects and designers, from hotel rooms, for example, the lighting solution is flexible, adapting to the required standards, albeit with substantial widths. The Applicant was initially surprised by the clear gain of homogeneity with the bottom reflector according to the invention when compared to: a metal sheet which is either blanked or polished or coated with a white reflector, side of the inner space, or a transparent sheet coated with a reflecting layer on the inner face, side of the inner space.

When the reflective layer is deposited behind the transparent plate, the light emitted by the LEDs crosses the thickness of the plate before it is diffused by the reflective layer. One plausible explanation is that this allows certain light rays to be guided on the plate to be diffused further into the glass pane and thus contribute to the pattern's homogeneity of illumination.

When the dedicated carton is formed of a transparent pasticone crate with a reflective layer, preferably the polycarbonate plastic is selected.

If the illuminating mirror were positioned without the bottom reflector and on a white wall, the submicron roughness would make the homogeneity and absorption of the very intense material even worse. The background reflector positioned facing the diffuser pattern against the surrounding structure allows creating a closed light box in order to diffuse the light from the LEDs in the diffuser pattern region.

The diodes are positioned to form a continuous illumination region in the lengthwise direction of the diffuser pattern. The "intragroup" distance between the adjacent diodes of the first group, preferably, may be identical for all diodes in order to simplify the overlapping of the beams. The arrangement of the diodes allows hiding the diode hot spots from the large angles for the user, always maintaining efficient illumination of the diffusion region not stretching too much.

Of course, the first and second PCB boards may form a single PCB board in particular, the PCB board being sufficiently flexible around the diffuser pattern. The option of realizing a surrounding structure containing diodes with an optimized distance from the diffuser pattern guarantees better efficiency. The diodes are positioned opportunely in the accesses of the diffuser pattern. For widths greater than 7mm, the second group of diodes for homogeneity is required, the illumination is very homogeneous up to a standard width of 230mm, even more preferably 200mm. In particular, the (maximum) width of the diffuser pattern (constant or variable) may preferably be less than 200mm, even less than or equal to 150mm, especially to provide a large surface for the (central) mirror region.

A (substantially) straight main reflector allows more accurately positioning its edge in front of the edge of the diffuser pattern and more easily installing the second group of diodes with F 'to normal or close to normal.

In the present invention, "electroluminescent diode" (or abbreviated diodes) is understood as a quasi-punctual source, generally inorganic, typically based on a semiconductor chip, a source other than an OLED obtaining an enlarged illuminating surface.

Preferably, according to the invention, when a distance from an element (emitter face of the diode, wall of the surrounding structure, the crate, base or edge of the profile, mirror support, etc.) to the edge of the diffuser pattern is mentioned , the distance ("horizontal") between the orthogonal projection of the element on the plane of the diffuser pattern and the edge of the diffuser pattern is considered. For example, they are D1, D2 (D3 and D4 defined later).

Preferably, to simplify the exposure, the diodes of each group are selected with the same (single) main direction of emission F.

A divergent beam is selected to sufficiently propagate the light over the diffuser pattern. And preferably, for uniform illumination, the diodes of each group are selected with the same spectrum, mono or polychromatic. The emission cone may be symmetrical or asymmetric with respect to F. The emission cone may be, for example, Lambertian. The dispersion angle δ of a material is the angle between the direction of the maximum luminous intensity (Imax) of the reflected light and the direction of the luminous intensity of the value ImaxS 2, when the luminal intensity curve can be assumed to be symmetric around the direction of Imax (which is typical when the angle of incidence is 0). The reflection of a material is said to be perfectly diffused when δ is 60 °. If δ is close to 0 °, the reflection or transmission is considered to be specular (also called regular). If θ <δ <15 °, the reflection or transmission is said to be diffuse narrow. If 15 ° <δ <45 °, the reflection or transmission is said to be broad diffusion. If 45 ° <δ <60 °, the reflection or transmission can be considered to be of full diffusion. The light transmission TL and the light reflection RL according to the invention are calculated in the classical manner under a D65 illuminant in accordance with EN410.

In the preferred embodiment, the reflecting layer is a diffuse reflection layer, in particular white, preferably with a light reflection RL greater than or equal to 80% of the outer side, opposite the inner space.

For example, a paint, a lacquer, an enamel.

A lacquer is a non-transparent, generally opaque coating, and which may contain at least one polymer resin, at least one pigment, and in general mineral fillers. The polymer resin serves to bond the pigments and mineral fillers, while the pigments are intended to provide the desired color and opacity. The lacquer may contain, like any lacquer, a binder based on synthetic resin, of a polymeric nature. Preferably, the binder is formed from acrylic resin, in particular cross-linked with melamine and or with an isocyanate. The binder may also be a polyurethane resin, obtained by cross-linking, by an isocyanate or polyisocyanate, hydroxylated resins, in particular polyester or polyether resins or, preferably, acrylic resins (or polyacrylates). This particular combination especially allows to obtain a low water permeability, good mechanical properties (for example in terms of scratch resistance). The lacquer binder may additionally contain or be based on alkyd resin (s), obtained by a chemical reaction between at least one polyol, at least one polyacid and at least one fatty acid or an oil. Such alkyds are preferably short chain oils, i.e. the oil or fatty acid content contained in the resin is preferably less than or equal to 40%. The polyols may be, for example, glycerol or pentaerythritol compounds. The polyacids may be phthalic anhydride based. The oils may be sicative (such as hemp, wood or China oil), semi-synthetic oils (such as soybean oil, talloyl, safflower or dehydrated castor), or non-sicative oils (such as copra or castor oil). To improve their water-resistance properties, alkyd binders can also be modified by monomers such as styrene, vinyltoluene or acrylates or by phenolic or epoxy resins. The aminoplast alkyd resins which crosslink under the effect of heat are particularly advantageous lacquer binders. The aminoplast crosslinker is preferably a urea-formaldehyde or melamine-formaldehyde resin, which confers a good water resistance, especially when in the ratio of 20 to 30% by weight relative to the dry alkyd binder. The lacquer may additionally include a thermoset acrylic resin based binder, for example, obtained by crosslinking an acrylic resin carboxylated by an epoxy resin, phenol formalamin or melamineformol or an isocyanate, of a carboxamide functional acrylic resin by an epoxy binder or alkyd, or an acrylic resin with epoxy function by acids or polyamines. The lacquer preferably has a water permeability at 25 ° C, expressed in cm 3. cm. cm-2. s'1. Pa 'of less than 10' 6, or even less than 5.10 ", and even less than 10".

An adhesion promoting agent may preferably be dispersed in the lacquer and / or as a layer sandwiched between the lacquer layer and the bottom reflector plate. Glass-promoting agents, such as silanes, may also be dispersed in the lacquer. The lacquer may contain pigments, organic and organic, preferably minerals. Among the pigments employed are, for example, titanium or zirconium oxides optionally doped with transition element ions, or else mixed zirconium oxides (ZrSiO4). The pigments are preferably free of heavy metals such as cadmium or lead. The lacquer may additionally contain mineral fillers designed to optimize physicochemical parameters, for example, their viscosity. The total content of mineral species (pigments and fillers) contained in the lacquer is preferably expressed as a percentage by mass in relation to the dry extract, comprised between 40 and 70%, or even between 50 and 60%. The thickness of the lacquer is, for example, between 40 and 60 mm. The clarity L * may be at least 65. A reflective layer is preferred by diffuse reflection on the side opposite the inner space in that it renders the colors better than a specular reflection layer. The color temperature on the mirror is then closer to that of the diodes.

This layer may be of diffuse reflection and specular, for example with a coefficient in the diffuse reflection equal to at least 0.8 times the coefficient in the specular reflection.

In an alternative and satisfactory embodiment, the reflective layer is a silver-based specular reflection layer (including essentially silver and typically coated with a protective layer) with a light reflection RL preferably greater than or equal to 85% to 88% and even 90%, on the internal space side.

The edges (internal and external) of the diffuser pattern may be straight or curved. It is preferred that the diffuser pattern is decentralized, that the mirror be preserved in the central region of at least 500mm by 500mm. The inner edge is preferably at least 200mm away from the middle of the facade glazing. The peripheral region between the outer edge and the glazing segment of the mirror facade is preferably at least 25mm.

From a dimensional point of view, at least one of the following characteristics can be provided: the width of the diffuser pattern is 30% less than the width of the facade pane (including 20% or 10%), the length of the diffuser pattern is of at least 50 mm, preferably at least 100 mm and even at least 200 mm and in particular, substantially equal to the length of the lateral or longitudinal edge of the angular facade pane (square, rectangular, etc.). The choice of making a "dedicated" box for a diffuser pattern in a restricted region of the total surface of the glazing is more economical than a "total" box that substantially covers the back of the facade glazing, in particular for large, less 500mm in length and heavy.

Preferably, the distance between the main reflector and the segment of the bottom reflector of the plate is at most 5mm. It is preferred that the surrounding structure has no walls connecting the main reflector to the diode support member or any other wall under the diffuser pattern. It is preferred that the surrounding structure is substantially rectangular (s) and extends straightly, optionally L-shaped or U-shaped (forming a frame). It is preferred that: the length of the surrounding structure and the bottom reflector is at least equal to the length of the diffuser pattern, the length of the surrounding structure and the bottom reflector is at least 50mm, preferably at least 100mm and even 200mm and , in particular substantially equal to the length of the lateral or longitudinal edge of the facade pane, with corners (square, rectangular, etc.), for an elongated pattern, the diode of the end of the first group (and the second group) is less 1 cm from the first side edge of the diffuser pattern and the other diode of the end of the first group (and the second group) is less than 1 cm from the second side edge of the diffuser pattern. The surrounding structure preferably includes one or more inner walls in the devoid of diodes which are less than 10 mm away from the edge of the diffuser pattern and possibly at most 5 mm apart.

For W1 or W'1 less than or equal to 70mm, it is preferred to have, for greater efficiency: for the elongated pattern, a distance Dr2 between the second longitudinal edge and the main reflector (in particular the base) devoid of maximum diodes 10mm and preferably not more than 2mm, and even at the edge, without exceeding the diffuser pattern, and eventually exceeding by 5mm the inner face of the bottom reflector, to the frame pattern, a distance Dr between the other surrounding structure (in particular the base) devoid of diodes and the other contour of a maximum of 10 mm and preferably of a maximum of 2 mm and even at the edge, without exceeding the diffuser pattern, and possibly exceeding the inner face of the bottom reflector by a maximum of 5 mm. The surrounding structure includes in particular: profile or profiles optionally devoid of diodes, in particular L-shaped or U-shaped, with the side of the facade glazing an edge towards the internal space, a recessed edge of at most 5 mm preferably or at the edge of the diffuser pattern or exceeding the edge of the diffuser pattern by a maximum of 5mm, and the (or each) hook profile in the inner space and devoid of diodes, includes, on the side of the facade pane, an edge towards the inner space, of not more than 5mm preferably at the edge of the diffuser pattern or exceeding the edge of the diffuser pattern by at most 5mm, and / or a wall or flank of a crate of rectangular or square section or a spacer of rectangular or square section, flank or spacer devoid of diodes, recessed not more than 5mm preferably, or at the edge of the diffuser pattern or exceeding the edge of the diffuser pattern of at most 5mm.

Thus, the bottom reflector side, if any, of the profile (s) of the surrounding structure or the profile (s) of engagement of the surrounding structure preferably exceeds the bottom reflector opposite the diffuser pattern by a maximum of 5 mm.

On the rear face side of the facade glazing, the one or more edges of the profile (s) of the surrounding structure or the profile (s) of engagement of the surrounding structure preferably do not extend beyond the rear face to the diffuser pattern. By way of simplification, the surrounding structure may have a rectangular contour and may accompany the contour of the diffuser pattern preferably by means of straight (preferably metallic) profiles and having a U-shaped or L-shaped section, in particular contiguous or less than 1 mm spacing or joined by a joint (preferably sealant).

If necessary, replacing one or the mirror regions outside the inner space of the surrounding structure may be replaced by one or more decorative or functional regions (switch, etc.), for example a partial, preferably center, mirror is formed and a Decorative varnish (white, colored, etc.) is preferably used in the periphery. The diffuser pattern may even be on the periphery and encircle the mirror layer finished by the decorative layer (enamel, etc.). It is preferred that the surrounding structure remains concealed by the mirror layer and / or by the decorative layer, as in securing the mirror to a wall.

In the case of a surrounding structure which describes a frame, around an elongate pattern especially engraved in a rectangular region, the surrounding structure may contain, laterally connecting the main reflector and the support piece, a first part or side part along a the first side edge of the elongated pattern, which contains a PCB plate said third plate having a third group of diodes identical or similar to the first group of diodes, the third PCB plate optionally includes a reflective cover layer around the third group of diodes, with : a distance D3 between the first side edge and each emitting face of the third group of at least 10mm, preferably at least 12mm and even at least 15mm and preferably of at most 40mm and more preferably of at most 30mm and even at the maximum 20mm, a distance e3 between the facade glazing (preferably with the mirror layer) and each emitting surface of the facade a distance ≤ 3 between the inner face of the bottom reflector and each face emitting the third group such that the difference in absolute value e3 - e '3 is less than or equal to 20mm is preferably smaller or equal to 10 mm. And the surrounding structure may contain, laterally connecting the main reflector and the support part, a second part or side portion containing a PCB plate said fourth PCB plate having a fourth group of diodes identical or similar to the first group of diodes, the fourth The PCB plate optionally includes a reflective cover layer around the fourth group of diodes, with: a distance D4 between the second side edge and each emitting face of the fourth group of diodes of at least 10 mm, preferably at least 12 mm and inclusive of at least 15 mm and preferably at most 40 mm and more preferably at most 30 mm and even at most 20 mm, - a distance e4 between the facade pane (preferably with the mirror layer) and each face emitting the fourth minor diameter group or equal to 10 mm, - a distance e'4 between the inner face of the bottom reflector and each face emitting the fourth group of diodes such that the difference in The absolute value e4 - e '4 is less than or equal to 20mm, preferably less than or equal to 10mm.

Of course, the first, second, third, fourth plates form a single PCB plate, in particular a sufficiently flexible PCB plate.

When the elongated pattern has the length LI greater than or equal to 200mm, if the diodes are installed along one or more lateral edges of the elongated pattern, a certain unevenness is favored locally which, in spite of this aspect, is acceptable.

In another case, with a surrounding structure depicting a frame, around an elongate pattern, the surrounding structure may contain, laterally connecting the main reflector and the support piece: a first part or side portion along a first side edge of the elongate pattern, devoid of diodes, a second part or side portion along a second side edge of the elongated pattern, devoid of diodes.

In the absence of the third group and the fourth group of diodes it is preferred to have, for a greater efficiency: a distance Dr 3 between the first side edge and the first side piece of at most 10 mm and preferably of at most 2 mm, and even at the edge , without exceeding the diffuser pattern, and eventually exceeding by 5 mm the inner face of the bottom reflector, - a distance Dr4 between the second side boll θ the second side piece of at most 10 mm and preferably of at most 2 mm, and up to even at the edge, without exceeding the diffuser pattern, and eventually exceeding the internal face of the bottom reflector by at most 5mm.

In a preferred embodiment to suppress hot spots from large angles, the surrounding structure includes diodes of the first, if not the second, group and other diodes (along the side edges of an elongated pattern, for example), the distance between the emitter face of each of the diodes and the edge of the nearest standard is at least 10 mm and preferably at most 40 mm. Preferably, the distance between the emitting face of each of the diodes and the edge of the nearest standard is at least 12mm and even at least 15mm and preferably at most 30mm and even at the maximum 20mm. It is preferable to significantly reduce the view of the small angle hot spots of a user, at a short distance from the mirror in the central region, that: when W1 <70 mm, the first longitudinal edge of the elongated pattern is the innermost, the reflector along the second longitudinal edge is devoid of the second PCB board with diodes or when W'l <70 mm, the injection contour of the frame pattern is the innermost contour, and the other contour is devoid of the second plate PCB with diodes.

When W1 <70 mm or when W1 '<70 mm, the main reflector may be oblique or preferably has a flat inner wall which forms a maximum angle of 5 ° with the facade pane and preferably of at most 10 ° with reflector. The elongated pattern may be etched in a rectangular region R or the pattern is square or discoid or presented as a frame, and the surrounding reflecting structure forms a rectangle (and the other surrounding reflecting structure forms a rectangle).

The width of the molded edge can be of maximum 4mm and even 2mm or even of Imm. The term wall for the bottom reflector is adopted in the broad sense and does not imply a minimum thickness.

It could be a film or a sheet. The wall may be malleable or rigid, mineral or organic. The term plate for the bottom reflector is adopted in the broad sense and does not imply a minimum thickness. It can be a film or a sheet, it can be malleable or rigid, mineral or organic. It is preferred, however, for a better mechanical behavior, that the bottom reflector be of rigid wall (bottom of a crate or sheet). It is still preferred, for even better thermal behavior, a mineral glass plate having a thickness of less than 6mm and at least 0.5mm. The transparent, flat or concave wall towards the inner space may be a plate, the surrounding reflective structure (and even the other surrounding reflective structure) forms a spacer between the sheet-shaped bottom reflector and the facade glazing the surrounding structure (including the other reflective surrounding structure) extends up to a maximum of 5mm span with the facade pane.

For the surrounding structure, four U- or I-shaped profiles are typically selected with clamps or four spacers of rectangular or square section. The surrounding structure (or other surrounding structure) may preferably comprise a wall or inner walls in the regions devoid of diodes which are less than 10 mm from the edge of the diffuser pattern and possibly at most 5 mm. The surrounding structure (or other surrounding structure) includes, for example: profile or profiles optionally devoid of diodes, in particular L-shaped or U-shaped, with side pane of the facade an edge towards the internal space, 5mm or preferably at the edge of the diffuser pattern or exceeding the edge of the diffuser pattern by a maximum of 5mm, and the (or each) hook profile in the inner space and devoid of diodes includes, on the side of the facade pane, an edge towards the inner space, recessed edge of not more than 5mm preferably or at the edge of the diffuser pattern or exceeding the edge of the diffuser pattern by a maximum of 5mm, or a wall or flank of a crate of rectangular or square section or a spacer of rectangular or square section, flank or spacer devoid of diodes, recessed by at most 5mm preferably or at the edge of the diffuser pattern or bypassing the edge of the diffuser pattern at m 5mm.

On the side of the rear face of the facade glazing, the eventual profile edge (s) of the surrounding structure or the engaging profile (s) of the surrounding structure does not (preferably) back on the diffuser pattern. The plastic bottom reflector may be a sheet extended on one side and the other by the main reflector and the backing piece, which forms a monolithic piece said crate.

You can consider any crate section. It is preferred that the crate has one or more edges toward the inner (or opposing) space of at least 5 mm for attachment, for example, with the use of an adhesive (double-face) otherwise, a or preferably at least two engagement profiles, as clamps preferably mechanically secured to the crate.

The glass pane can be of translucent or extra-clear mineral glass. With respect to the extra-clear glass, application WO04E3 025334 can be consulted for the composition of an extra-clear glass. The selection may fall in particular on a silica-soda-glass glass with less than 0.05% Fe III or Fe203. For example, SAINT-GOBAIN Diamant® glass, SAINT-GOBAIN Diamant Solaire® glass SAINT-GOBAIN Albarino® glass (textured or smooth), Pilkington OptiWHITE® glass, B270® glass of Schott.

In addition, mineral glass is preferred for the facade glazing because of its multiple advantages: glass has good heat resistance, it can be close to the diodes, although they are hot spots, the glass is mechanically resistant, so it can be cleaned easily and not scratched, which is of particular interest for panels installed in places that require strict hygiene, the glass meets the requirements of fire safety standards.

This may be the case, for example, especially depending on the aesthetic behavior or the desired optical effect eH or the destination of the mirror, of the standard composite glass, such as SAINT-GOBAIN GLASS Planilux® glass, slightly colored green, extra-colorless glass (neutral) such as Diamant® and Diamant Solaire® glasses from the company 5AINTG0BAIN GLASS,

According to one feature, the diodes may be encapsulated, i.e., contain a semiconductor chip and a shell, for example of epoxy or PMMA resin, encapsulating the chip. The functions of this housing can be multiple: protection against oxidation and humidity, conversion of wavelength, diffuser element. The diode may be, for example, a semiconductor chip having a dimension of the order of hundreds of millimeters or a few millimeters; and possibly with a minimum encapsulation, for example, of protection. It is not necessary to use optical components such as lenses that direct the light emitted by the diode to the privileged regions. The diodes may be immersed in a common protective material (sealing against water, dust, etc.).

The robustness of the diodes is particularly interesting for intensive use such as, for example, public transport such as train, plane, car, transatlantic ride, etc. 0 or the groups of diodes can be coupled to pilot means which allow to emit light, either uninterrupted or intermittently, with different intensities, either of a certain color or of different colors, especially depending on the amount of natural light. It is possible to provide that: the length of the PCB plate is substantially equal to the length of the support piece, the first PCB plate (each PCB plate) is less than 1 cm in thickness, preferably less than or equal to 5 mm, the first PCB plate is flexible and, for example, surrounds the diffuser pattern, the diodes and / or the PCB board are free of coating, varnish or encapsulation.

A reflective surface to ensure the mirror function is usually a silver-based layer. The mirror may be the SGG Miralite product of the Applicant company, with a rust protection paint. The mirror according to the invention may include any other functional coating (against scratches, impurities, etc.) on the back face of a heating layer for anti-condensation effect. The illumination of the first illumination region may be decorative, architectural, signaling or bulletin board. The illuminating mirror and illuminator can be designed, in particular: for buildings such as ceiling lights, wall plate; for public transport, in particular public transport, train, subway, tram, bus or water or air vehicle (airplane), for street or urban lighting, for an urban furniture pane such as a bus, balustrade, showcase, showcase, to a shelf element, to a pane of internal furniture, a bathroom wall, a furniture.

If necessary, it is possible to replace the mirror region or regions outside the inner space of the surrounding structure by one or more decorative or functional regions (switch, etc.), for example forming a partially centered partial mirror and using an enamel decorative (white, colored, etc.) preferably in the periphery. The diffuser pattern may even be on the periphery and encircle the mirror layer finished by the decorative layer (enamel, etc.). It is preferred that the surrounding structure remains concealed by the eS mirror layer or the decorative layer as well as the attachment of the mirror to a wall. The invention finally proposes a method of forming an illuminating mirror comprising a plurality of diffuser entities in a said facade glazing containing, on the rear face of a silver layer said mirror layer, diffuser entities etched in a rectangular region Rtot Wtot width greater than 230 mm, the method including dividing the rectangular region Rtot into several rectangular regions R 1, R 2, R 3, each having a width of less than 230 mm defining a given diffuser pattern, each region R 1, R 2, R 3 being surrounded by a reflective surrounding structure with the diodes having a distance of at least 10 mm, preferably at least? 2mm and even at least 15mm and preferably of at most 40mm and more preferably of at most 30mm and even of at most 20mm between each emitting face of the diodes and the rectangular region, each surrounding reflective structure being preferably under the mirror layer, each circular structure reflecting member being in contact with or even attached to a bottom reflector or each surrounding reflective structure forming part of a monolithic crate shape.

External side, opposite internal space. It is preferred that all surrounding structures form part of bins (with a possible common wall) or spacers (with a possible common wall) with a sheet-shaped bottom reflector. The length of at least one region R 1 to R 3 is at least 200 mm preferably and even at least 400 mm.

Preferably, the width of a region R 1 to R 3 is at most 150 mm and even at most 120 mm and at least 10 mm and preferably at least 20 mm.

There may be provided a mirror fixing bracket, said mirror support, preferably metallic (and rear face side), secured to the rear face and / or to the bottom reflector, which especially includes a latch opening or fastening devices to a wall, especially mural or mobile. The mirror support may then be devoid of the part which extends beyond the glass pane of the facade and is selected from: profile or profiles fixed to the rear face, preferably metallic, and a metal plate preferably secured by gluing or mechanically external main face of the bottom reflector and with a fastening means (hook, retaining device, etc.). The mirror holder in particular forms: a monolithic frame in the central region of the mirror and or peripheral of the mirror, in particular distinct from the dedicated or common waterproof housing, a frame spaced apart or cast to the case, in particular produced as a frame (two , three or four spaced or contiguous straight profiles) in the central region of the mirror and / or peripheral mirror, in particular with at least one profile distinct from the dedicated impermeable housing (of the surrounding structure) or the common, spaced or cast housing and optionally at least one profile serving the surrounding structure, or two lateral or longitudinal profiles to the facade pane eventually serving the surrounding structures of various diffuser patterns. It may be preferable to set aside a clearance in the central region to install a mirror-layer anti-condensation heating element. The bottom reflector may be of any shape, rectangular or round or square. It can be a metal frame or plastic or glass around the facade pane to serve various diffuser patterns and leave reserved to the center a space for attachment to the wall. The mirror carrier is, for example, spaced or fused to the exterior of the surrounding structure and / or the dedicated or common carton, in particular with a sufficiently shifted engaging aperture of the bottom reflector for attachment to a fastening wall (movable, wall). The mirror holder may have a latch aperture accompanying a plane parallel to the rear face or normal to the rear face. The fixing wall (wall or movable) may have one or more securing hooks.

Profiles can be used, in particular using profiles for the surrounding structure, not too resistant to participate in the fixation of the mirror, typically very thin.

In a first embodiment, the bottom reflector is a sheet (flat or concave towards the facade pane, without edges facing the rear face), the mirror support includes a profile forming a wall of the surrounding structure (support piece , main reflector etc.), in particular a straight U-shaped or closed profile of the square or rectangular type. The mirror holder is, for example, an adhesive (double-face) on the bottom reflector, preferably identical (or similar) to a fixing adhesive (double-face) (its attachment) to the facade glazing.

This mirror support may have at least one part or end surpassing the bottom reflector (under the rear face, on the mirror layer) for attachment of the illuminating mirror to a wall (preferably two protruding parts or ends of the reflector two opposite edges of the bottom reflector). The profile is preferably metallic (aluminum, etc.) at least 1.5 mm thick. The double-face adhesive between the mirror holder and the bottom reflector may have a width (contact with the bottom reflector) of at least 10mm, being especially similar to the thickness with the facade glazing and even a thickness of hair less 1 mm.

In this embodiment we take advantage of the fastening profile to form the housing and even the support part. This profile may be more peripheral than the diffuser pattern or be in the central region of the mirror.

In a second embodiment, the bottom reflector is a plate (flat or concave without edges on the back face), the mirror support forms a wall of the surrounding structure (support piece, main reflector, etc.), in particular a profile (rectum) with a U-shaped or closed section, of the rectangular or square type. This mirror holder is secured with an adhesive over the segment of the bottom reflector.

Further details and advantageous features of the invention will emerge from reading the examples of illuminating mirrors according to the invention, which are illustrated by the following Figures: Figures 1, 2, 3, 4, 5, 6, 7, 8, 9, 9 ', 9 "are schematic, if any, partial cross-sectional views of an illuminating mirror of electroluminescent diodes in the different embodiments of the invention: Figures 1', 2 ', 2a, 3a, 4a, 5a, 5'a, 5 ", 6a, 6a, 7a, 8a are schematic front views (rear face side) of the illuminating mirrors; Figures 1 '1, 1b to 11 show examples of diffuser patterns and array of diodes on the PCB board,

Figures Im and ln show examples of PCB and diode profiles used for two adjunct diffuser patterns.

It is understood that, for the sake of clarity, the different elements of the objects (including the angles) represented are not necessarily reproduced in scale. Figure 1 schematically shows a longitudinal cross-sectional view of an illuminating mirror of electroluminescent diodes 100 in a first embodiment of the invention. The mirror 100 includes a flat mineral glass facade pane 1, for example a rectangular glass sheet, with a first main face 11 forming the rear face with side and longitudinal edges, and a second main face 12 forming the face and a segment 13, the glazing has a thickness of preferably less than 6mm, and a light transmission of at least 85%, such as PLANILUX glass marketed by the applicant company. The back face 11 is coated with a silver-based metal layer 2 (produced by silver coating) said mirror layer, which provides the mirror functionality on the front face, with a light reflection RL of at least 85%, coated with a (not shown), the mirror layer present in particular at a central region of the facade pane and at the periphery of the pane. Take as an example a glass containing a MIRALITE or MIRALITE EVOLUTION partial mirror marketed by the applicant company.

At the rear face, a diffuser pattern 3 is adjacent the mirror layer 2 in the central region, the mirror layer surrounding the diffuser pattern, preferably alone or optionally with a masking layer (decorative enamel, etc.).

More precisely, it is preferred that the back face 11 include the mirror layer with one or more discontinuities formed or filled by the diffuser pattern and even other diffuser patterns. The diffuser pattern is capable of modifying the light transmission of the facade pane 1, for example, so that it is comprised between 40 and 85% on the side of the front face of the mirror. The diffuser pattern prevents a very intense transmission of the rays (direct lateral or reflected by the particular background reflector) emitted by the diodes, substantially diminishes the glare of an individual looking at the mirror 100. The facade pane 1 with the diffuser pattern 3 presents a haze of at least 90% or at least 95% on the front face side of the mirror measured by a transparency meter in a classical manner. The diffuser pattern on the rear face 11 of the glass is preferably obtained by texturizing the preferably coated glass of the mirror layer, in particular by spraying sand. The standard can also be formed by the acidification of glass just as it is made for SAINT-GOBAIN GLASS Satinovo® glass.

Finally, the diffuser pattern 3 may be a diffuser layer (in this case, preferably a partial mirror is formed directly) of mineral essential preference, for example, by screen-printing with a (white) enamel, screen printing having the advantage of enabling the obtaining of any type of drawing with well-defined delimitations. It may be an enamel such as that made for SAINT-GOBAIN GLASS Smoothlite® glass or a Lambertian enamel, for example, as described in the patent application WO2012168647

To form a luminous pattern, a first group of inorganic electroluminescent diodes 41 (or DEL) were installed along the longitudinal edge 31 preferably more interiorly of the diffuser pattern 3. The choice of the inner edge allows avoiding a visual discomfort (hot spots of small angle, less than 10 °) when a person looks at the central region of the mirror at close range.

Preferably, for simplicity, the PCB plate 40 is parallel at the inner edge and along the inner edge 31. The diodes are aligned in a row and distributed regularly on the first bar-type PCB 40 (rigid or malleable) ), rectilinear, in particular produced in aluminum, and optionally with a diffuser layer around the diodes 41, for the recycling of the rays, in the form of a white paint or lacquer. It is preferred that the end diodes are less than 1 cm from the lateral edges of the elongated pattern.

To simplify assembly, each diode 41 has an emitting face perpendicular to the PCB 40 board ("top emitting" in English) rather than a side emitting (English language). The first PCB plate 40 is supported (behind) by a profile said support piece 51. Here a heat conductive bonding material 6 is inserted, which is, for example, a glue or double-sided adhesive tape to obtain thermal dissipation best. The adhesive tape has the advantage of providing a calibrated thickness, allowing the diode PCB to be perfectly flat and ensuring that all diodes are at equal distance from the reflector or the diffuser pattern. In addition, the adhesive tape may be pre-attached to the PCB. It is also possible to use preferably a thermal grease between the PCB and the base, as well as the compound CK4960® marketed by the Jetart company. The PCB plate 40 may be metallic. In this case, the diodes are soldered onto tracks that are electrically insulated from the metal material of the PCB. The metal material of the PCB being thermal conductor, the PCB can be directly pressed against the thermal conductive base to obtain the thermal dissipation. In this case, for example, the attachment of the PCB to the base can be performed by clipping and / or screwing, however, a double-sided adhesive can be maintained.

The diodes 41 are of the SMD type or the "Chip on Board" type. Each of the diodes 41 has a given emission spectrum in the visible, for example a white light, and with a main emission radius F, said first main radius, forming an angle of less than 5o with respect to the facade pane 1 If the radius F is steeply inclined toward the mirror layer, the LEDs are more easily viewed by the user.

To contribute homogeneous appearance, the diodes are preferably selected with the same (single) direction of emission F. For uniform illumination, the diodes are selected with the same visible, mono or polychromatic spectrum. A white or yellow light is favored. The emission cone may preferably be symmetrical with respect to F. The emission cone may be, for example, Lambertian. The beam of each diode is divergent and defined by a half-height half-height of 60 °. The adjacent diode bundles of the first group overlap on the surface of the diffuser pattern. The distance ei between the emitting face and the back face (the mirror layer) is greater than 5mm, preferably greater than or equal to 10mm to prevent the diode from heating the paint and the silver coating and are degraded. The distance ef between the emitting face and the bottom reflector is such that ei - ef <20mm, preferably <10mm, in order to make the illumination more homogeneous. The radius F may preferably be centered. The distance ei is substantially equal to f and between 15mm and 25mm.

To make the illumination efficient and durable, a light reflection box is formed by defining an inner space 14, dedicated to the diffuser pattern, and comprising: a reflecting surrounding structure surrounding the diffuser pattern, having an outer length greater than or equal to the length LI and having an outer width greater than or equal to the width W1, glued to the facade pane by the rear face 11 with an adhesive 61, for example, liquid-water-tight, in particular a double-sided adhesive tape, with at least 5 mm of spacing or, to become impermeable, joined by so-called sealing gaskets which are the sealant 63, or, as an option, a part forming a monolithic frame (preferably rectangular), a reflector in the form of a transparent sheet 1 ', said bottom, as a glass pane of mineral glass or a plastic coated on the back main face 11' opposite the main face 12 'opposite the diffuse pattern sor 3, with a reflective layer preferably of diffuse reflection 7, white, which is a lacquer or paint or an enamel, the bottom reflector with a length longer than the length LI and with a width greater than the width W1, glued to the by means of an adhesive 62, for example a liquid water seal in particular, which is a double-sided adhesive tape, bottom reflector 1 'whose segment 13' is facing the segment 13 or preferably at least a few mm of lowering the facade pane 1 in the region of the diffuser pattern 3, which forms the top of the box if necessary, impermeable to liquid water.

If the pattern design allows (as detailed below), it is preferred that the reflective surrounding structure forms a rectangular frame from two, three or four straight (even curved) profiles and preferably with section (constant), height (constant ) and material. In fact, you can select both the profiles and the sides of the diffuser pattern, for example, six profiles for an L, etc.

When the diffuser pattern is elongated, etched into a rectangular region; defined by two longitudinal edges and two side edges, the reflecting surrounding structure includes in this case, for example, four U-shaped profiles 51 to 54 identical with a base perpendicular to the facade pane and on one side and the other on the base two wings or edges oriented towards the internal space 14, thus: the support part 51, reflecting light from one side and the other of the first PCB plate, with a base 5 perpendicular to the facade glazing and on one side and the other from the base two edges 5a , 5b directed towards the inner space 14, a said main reflector 52 positioned facing the first PCB plate, for laterally dividing the light, the first and second side pieces 53 and 54 (see Figure 1a) along the side edges of the elongated diffuser pattern, for maximum recycling of the light rays. The wing 5a of the facade pane side support part is fixed to the rear face 11 by the double-face adhesive 61 which is a strip along the support piece with a width of at least 5mm which is said contact width with mirror layer (protected). The wing 5b is secured to the bottom reflector 1 'by the double-sided adhesive 62, identical, for example, with a contact width of at least 5mm. The same applies to the profiles 52 to 54. By way of simplification, each adhesive tape 61 has been previously glued onto the wings 5a on the side of the facade pane prior to its attachment to the mirror layer. Then, after gluing, without necessity the four joints are realized. The joints 63 are, for example, white or transparent silicone, even this double-sided adhesive again, however, the execution is more complex.

Directly, each profile 51 to 54 of the surrounding reflective structure is: metallic, preferably aluminum, anodized, crude, polished or optionally coated with a diffuse reflection layer around the diodes 2, for the recycling of the rays, or plastic, for example, PMMA or PC, coated with a specular or diffuse reflection layer for the recycling of the rays, in the form of a white paint or lacquer on the inner or outer face.

In a simple manner, the reflector profile 51 to 54 is metallic, straight, of U-shaped cross-section, with a thickness of less than or equal to 3mm, or even 1mm.

As an option, the reflector profile 51 to 54 is U-shaped, rectangular coated PC or PMMA with a thickness of less than or equal to 5mm. The main reflector, the support part, the first and second side pieces framed by the diffuser pattern, preferably accompanying a rectangular frame, and are spaced, for example, at a constant distance from the diffuser pattern. The first PCB board 40 does not require encapsulation, tropicalization varnish for waterproofing against water if the carton is impermeable.

As an option, the profiles 51 to 54 are less than 1 mm apart are to be joined by a joint and the PCB board and the diodes are impermeable to water. The double-face adhesive presents on substantially all of the surrounding structure provided a satisfactory first level of seal and maintains a robust and perennial fixation. On the other side edge of the facade pane 100 the means may be duplicated to produce a second efficient, homogeneous and durable light pattern: according to diffuser pattern, second PCB board with diodes, second reflective surrounding structure 51a, 52a, second reflection reflector as well as the second fixture (and even the second gasket). The first PCB board 40 includes an electrical power cable 91 which comes out of the support part 51 through an aperture sealed by means of a wire clamp, the cable leading to a connector 92 and to the connection cable of the second PCB board to the second diffuser pattern. As shown in Figure 1A, the second PCB board (as the first PCB board) is fed electrically by a power cable 91 'which leaves the support piece 51a of the second plate through a sealed opening and connected to an atmosphere resistant transformer 93 wet. It is preferable to avoid the realization of a surrounding structure by the diffusion element 3i of little extent (typically less than HOmm in length, even less than 200mm in length) in order to preserve homogeneity and efficiency. It is still preferable not to sandwich separating reflective walls between the support piece and the main reflector in the pattern region.

In one example IA, an acrylic foam (hardened) acrylic with two main faces was selected as rubber or double-face adhesive tape (for IP44 seal) an acrylic adhesive (hardened acrylic) with an acrylic adhesive such as hyper joint H9012 (thickness 1, 2mm) including H9008 (0.8mm thick), sold by the company Nitto Denko, width reduced to 10mm. The gasket for the joints is a white or transparent silicone such as the RUBSON HP gasket.

The dimensions of the pieces and the distances between pieces are as follows: the surface of the pane of the facade 1 is 600x900mm and is a 4mm thick glass, the surface of the bottom pane 1 'is 480x160mm and is a 4mm thick glass , the U-shaped profiles 51 to 54 have a thickness of 1 mm, a length of 480mm, the width of the wings 51a is 20mm, the base 5 is 25mm wide side of the longitudinal edge, the distance between the segment of the pane 1 and the glass segment of the facade 1 is 45 mm, side edge side, the distance between the segment of the pane 1 'and the segment glass pane of the facade 1 is 65 mm, the width of the central region of the mirror is approximately 700 mm , the width of the peripheral region of the mirror between the inner edge and the segment is 7Gmm, the height H of the inner space (between the bottom reflector and the facade pane), therefore, is approximately 25mm.

In order to satisfy the IP 44 standard for sealing, the glazing 100 according to example IA is placed in an oven, the glazing 100 without fixing element (s) 8 has a wall of the wall type, the elements are described below. The greenhouse test for the seal follows the FCBA-AMB-FIN 004 protocol defined by the NF of furniture, according to the different cycles indicated in table 1.

Table 1

The test is conclusive: the seal is confirmed and the light box fastened reliably. With the alternative adhesive tapes already mentioned, the test is also conclusive.

A double adhesive tape that is too thick, more than 3 mm and even more than 2 mm thick, should be avoided.

By replacing the double-sided adhesive with a glue, ultraviolet or bicomponent, the seal is broken. In addition, the glue may leak into the inner (and outer) space rather than the optical performances.

Furthermore, as regards the fixing of the illuminating mirror 100, it is preferred that the mirror is not secured to the wall by the outer face of the sheet-shaped background reflector so as not to run the risk of tearing the adhesive 62 by sliding the bottom reflector or by overweight forward.

As an option, the main reflector is L-shaped and the base of the main reflector 52 lies below the shaped edge (for example, a bevelled segment of the facade pane) and the pattern 3 extends to or near this patterned edge . The main reflector 52 thus does not contain the diodes even if the outer edge of the diffuser pattern is interrupted at the shaped edge, so there is no formation of hot spots with small angles. The wing of the bottom reflector preferably does not exceed the standard by more than 5mm.

As an option, the base of the side reflector 53 or 54 is below the shaped edge (beveled segment of the facade pane) and the pattern 3 extends to or near this patterned edge. The reflector 53 thus does not carry the diodes even if the outer edge of the diffuser pattern is interrupted at the shaped edge, so there is no formation of hot spots with small angles. The wing on the bottom reflector side preferably does not advance below the standard by more than 5mm.

As an option, the wings of the U-shaped profiles can be oriented in opposition to the internal space and, as the case may be, install the diodes on the base in opposition to the wings, as the rear face of the mirror reflects the more lateral rays received. It is preferable to avoid for the surrounding structure the use of profile or profiles, especially in I, of a thickness of less than 5 mm and / or of contact width with the facade glazing and with the bottom reflector of less than 5 mm or fixed with hooking profiles in L (clamp) in the detailed form below. The illuminating mirror 100 is attached to a wall (movable, wall, ceiling, partition wall, etc.) using one or several profiles, said securing profiles 8, 81 to 84, here separated from one of the aforementioned profiles 51 to 54 of the structure surrounding.

For mechanical reasons, it is preferred that the bottom reflector in the form of a glass (mineral) sheet does not participate in the fixation as there is a risk of detachment of the adhesive adhesive tapes 62 and in that the (mineral) glass is extremely heavy .

Always in Example IA, four fastening profiles 81 to 84 forming a peripheral frame, contiguous, are used less than 15 mm proximal to the facade glazing segment. In fact, the bottom reflector is shifted inwardly relative to the edge of the facade glazing. The fastening frame 8 is therefore adhered to the region of the rear face which extends beyond the bottom reflector 1 '. Four profiles in U 81 to 84 are selected with a bottom and two edges facing the inside of the pane, each one: aluminum, 30 mm wide, 15 mm high (from the base) between the edges, 890 mm long , 1.5 mm thick, edges 5 mm apart from the facade glazing segment, the width of the double-sided adhesive tape 61 'on the 20 mm securing profiles. with an attachment aperture 80 on a wing (preferably in place of a double-sided adhesive or a glue).

In order to evaluate the fixing of the illuminating mirror, the illuminating mirror 100 is secured to a wall by engaging the hooks in the securing apertures, a weight of 1 kg is placed on the mirror 100 and the greenhouse test described in Table 1 is repeated. It is noticed that the fixation is intact: no mirror support profile has been corrupted or slid.

Optionally, if the fastening profiles are replaced by one or more fastening plates installed on the sheet-shaped bottom reflector on its outer face, it is perceived that the fastening is less reliable.

The profiles 81 to 84 are concealed by the mirror layer 2 and devoid of edge on the front face, unlike the prior art. The front face 12 of the facade glazing is devoid of concealment or fixation, including macroscopic steps or recesses of at least 1mm and also of texturising element of the surface for the diffusion of light. This allows you to easily clean the front face.

Instead of a U-section, a closed section typically rectangular hollow or solid can be used.

Always for example IA: the PCB board 40 contains 30 diodes, 10 mm wide, is flexible, and 1 mm thick, the PCB bar 40 and the diodes 41 have an efficiency between 80 and 90 lmuW, the distance ei between the diodes and the diffuser pattern is of the order of 10 mm, the distance ef between the diodes and the background reflector surface of the bottom reflector is of the order of 10 mm, the diodes, without optical components, are 3 mm high, less than 4 mm wide, with a regular distance between diodes of 10mm + ú-2mm.

As shown in Figure 1 which is a bottom view of the illuminating mirror 100, the diffuser pattern 3 is elongated, formed of five spaced diffuser elements 3i, in the form of rollers of the like or similar size engraved on a rectangular strip R (in full dash) . The width W1 of pattern 3, of the strip R is centimetric and less than 70mm. The diffuser pattern 3 is spaced from the segment 13 of the facade pane. The elongate pattern is defined by a first longitudinal edge 31, said inner, on the side of the central region of the mirror, a second, outermost, outermost edge 32, along the side edge of the facade glass 1, a first side edge 33 (high in Figure), a second opposing side edge 34. The dots show the contours (the segment 13 ') of the bottom reflector 1', which is not shown to show the Figure more clearly. The distance D1 between the inner edge 31 and each nearest emitting face on the first PCB board is at least 10 mm. The maximum distance Dmax between the inner edge 31 and the nearest emitting face and even most or each emitting face on the first PCB plate is preferably less than or equal to 40mm. The distance between the base 5a of the U-shaped support piece 51 and the inner longitudinal edge 31 is less than 20mm.

Preferably, the ends of the wings of the support piece are on the edge of the diffuser pattern and are of predetermined width for the installation of the diodes in the distance Dl of at least 12mm. It is preferred that the wing ends do not extend beyond the diffuser elements by more than 5mm, since the bottom reflector, due to its layer 7, produces a better reflector. The distance between the base of the main reflector 52 (without diode PCB board) and the inner longitudinal edge is less than 10 mm. Preferably, the ends of the wings of the main reflector 52 are at the edge of the diffuser pattern. It is preferred that the wing ends do not extend beyond the diffuser elements by more than 5mm, since the bottom reflector, due to its layer 7, produces a better reflector. The distance between the base of a side piece 53 or 54 and the side edge is less than 10mm. Preferably, the wing ends of this part 53 or 54 are on the edge of the diffuser pattern. It is preferred that the ends of the wings extend the diffuser elements from the lower part by more than 5mm, because the bottom reflector, due to its layer 7, produces a better reflector. The main reflector (such as the side pieces) could be oblique to the facade glazing, as in the prior art, but this aspect renders the piece more complex and the manner of securing the seal, being more laborious and imposing a minimal mirror peripheral region bigger.

In example IA: the width W1 of the elongated pattern (therefore, of the R region) is 40mm the length LI of the elongated pattern (hence, of the R region) is 42Qmm, the distance D1 is 15mm

A single row of diodes along the inner (or outer) longitudinal edge 31 is sufficient for the homogeneity of the illumination to normal, provided that W1 is less than or equal to 70mm, however, another row of diodes may be added along the edge If we want to further accentuate the luminous efficiency. Messe case, the main reflector contains this second row of diodes in its normal base to the facade pane in a maximum of 5o.

If the interest is to increase efficiency by adding a row of diodes after the product is designed, the seal between the profiles is easily corrupted by removing the bottom reflector, for example with alcohol. The same occurs for replacing the diodes (color change, fault, power change ...).

A single row of diodes along the inner (or outer) longitudinal edge is not sufficient for the homogeneity of the illumination to normal, if W1 is greater than 70mm. It is necessary to add another row of diodes symmetrically in the base of the profile of the main reflector 52, so in this case the outermost or even simplifying, to surround the whole pattern. In this case, the main reflector contains this second row of diodes on its normal base to the facade pane in a maximum of 5o.

In an example IB, the differences with example IA are as follows: width W1 of the elongated pattern (hence region R) is 116mm, PCB board 40 contains 90 diodes spaced apart with a regular distance of 15mm, to surround the whole pattern.

As shown in Figure 1a, the distance D2 between the outer longitudinal edge and each emitting face of the second row of diodes 42 in this case is at least 10mm. The maximum distance Dmax between the outer edge 32 and the nearest emitting face and even most or each emitting face on the first PCB plate is less than or equal to 40mm.

In addition, it is possible to install diodes (on the PCB board) at the side edges, supported, for example, by the side pieces 53, 54 of the surrounding reflecting structure. These diodes at the side edges do not exert a very significant influence on homogeneity, even though LI is greater than or equal to 200mm. The distance D3 between the side edge and each nearest emitting face, therefore, is at least 10mm. The maximum distance Dmax between the side edge 33 and the nearest emitting face and even most or each emitting face on the first PCB plate is preferably less than or equal to 40mm. The distance D4 between the opposite side edge and each nearest emitting face in this case is at least 10mm. The maximum distance Dmax between the side edge 34 and the nearest emitting face and even most or each emitting face on the first PCB plate is preferably less than or equal to 40mm.

When the PCB 40 is flexible, completely encircling the diffuser pattern 3 of a single PCB, with diodes regularly distributed, is simpler and faster than securing two groups of diodes on two PCBs along the inner and outer edges 31, 32 and to connect them by one of the side edges 33, 34 for a common electrical supply, the arrangement of the diodes along the edges depends on the design of the diffuser pattern. Whatever the diffuser pattern, it is ensured that the distance between each edge of the diffuser pattern and each nearest emitter face is at least 10 mm and preferably less than or equal to 40 mm. The reflective surrounding structure and the diodes are also positioned respecting D1 and D2, D3, and D4 and the background reflector to a diffuser pattern forming a single rectangular band R, as shown in Figure 1b. In the R range of the diffuser pattern, it is possible to have locally preserved one or more mirror regions, as shown in the dotted lines. Figure 1c shows a pattern formed by a series of diffusive elements 3i, round or oval, for example, of varying sizes, etched in a rectangular region R (or square if any) passing through the edges of the more decentralized pattern elements. It is then defined:

D1 as the distance between the inner edge 31 of the diffuser pattern 3 (hence also the inner longitudinal edge of the R region) and the nearest emitting face (always facing the inside edge), distance being at least 10 mm and preferably of at most 40 mm, D2 as the distance between the outer edge 32 of the diffuser pattern (hence, the R region) and the nearest emitter face of the diode array (always facing the outer edge) of at least 10 mm and preferably less than or equal to 40 mm, D3 as the distance between the first lateral edge of the diffuser pattern (hence also the R region) and the emitter face closest to the row of diodes (always facing the lateral edge) less than 10 mm and preferably less than or equal to 40 mm as for other diodes, D4 as the distance between the second side edge (hence also the R region) and the emitter face closest to the diode array (always facing the lateral edge ) , in at least 10 mm and preferably less than or equal to 40 mm as for the other diodes. The surrounding structure, the PCB board (s), the diodes are at equal distances from the R region. Figure Id shows a C-shaped diffuser pattern, the pattern recorded in a rectangular region R with two "longitudinal" edges 31, 32, a first edge 31 including the end edges 31e and 31'e. It is then defined:

D1 as the distance between the longitudinal inner edge 31 of the region R and the emitter face closest to the row of diodes (always facing the inside edge); D2 as the distance between the longitudinal outer edge 32 of the region R and the emitting face closest to the row of diodes (always facing the outer edge), D3 as the distance between the first side edge 33 of the region R and the emitting face (always facing the edge 33), D4 as the distance between the second side edge 34 of the region R and the emitter face closest to the row of diodes (always facing the edge 34).

D1 to D4 is at least 10 mm and preferably less than or equal to 40 mm. The Figure shows a 3 'discoid diffuser pattern, the pattern engraved on a square or rectangular R (if oval, elliptical) region. In this configuration, it is preferable to install the diodes around the disk, whether it forms a rectangular frame accompanying the rounded outline, whether the PCB boards and the surrounding structure are appropriate (sufficiently flexible) to form a circle, D is the distance between the edge 31 'of the circle and each face is at least 10mm and preferably less than or equal to 40mm.

Figures 1 to 4 show the location of the diodes 41, 42 required for good homogeneity of an L-shaped diffuser pattern, in which case it comprises an edge or "small arm" of length Lt and width Wt, which protrudes from a rectangular band R of width W1 and longer than Lt.

As shown in Figure 1f, when Lt is greater than or equal to 20mm by way of homogeneity, the first PCB board 40 is installed along the inner edge 36 of the edge and the inner edge 31 of the strip, thereby reproducing an L in a single curve PCB plate, for example) with a preferably constant distance D1 between the emitting face 41 and the inner edge 31 or 36 of at least 10 mm and preferably less than or equal to 40 mm.

Wt and W1 are less than or equal to 70mm, so it is not necessary to install the diodes equally on the outer edge of the edge 33 'and on the edges 32, 33 of the strip. As Fig. 1g shows, when Lt is less than 20mm by way of homogeneity, the first PCB plate 40 may be installed along the (small) edge of the edge 35 and the inner edge 31 of the strip, the extension is either a row of rectilinear diodes 41 (on a single PCB, for example) with a diffuser distance variable between the emitter face and the inner edge 31 greater than the inner edge 36 of the edge. The distance D1 at the small edge 35 is at least 10 mm and preferably less than or equal to 40 mm.

Wt and W1 are less than or equal to 70mm, so it is not necessary to install the diodes equally on the outer edge 33 of the edge and on the edges 32, 33 of the strip. The L-pattern may have other shapes, of F, comb, with an edge otherwise installed in the extension of the strip, optionally with one or other projections of width equal to or less than 20mm (shown in dotted), the diodes will be installed in the same way, straight.

As shown in Figure 1, when Lt is greater than or equal to 20mm by way of homogeneity, the first PCB plate 41 is installed along the inner (large) edge 36 of the edge and the inner edge 31 of the strip, and even the edge 35 (on a single curve PCB, for example) with a distance Dl between each emitting face and the inner edge 31, 35 or 36 of at least 10mm and less than or equal to 40mm.

Since W1 is greater than 70mm, the diodes are also installed at the longitudinal outer edge 32 of the strip. They can also be positioned around the whole pattern for the sake of simplicity.

As shown in Figure 1, when Lt is greater than or equal to 20mm by way of homogeneity, the first PCB board 40 is installed along the inner (large) edge 36 of the edge and the inner edge 31 of the strip, an L (on a single curve PCB, for example) having a distance between the face emitting the diodes and these inner edges 31, 36 of at least 10 mm and preferably less than or equal to 4 mm.

Since Wt and W1 are more than 70mm, the diodes 42 are also installed on the outer edge of the edge 33 'and the outer edge 32 and the side edge 33 of the strip.

For simplicity, they may also be placed around, then, on the edges 35 and 34, edges of the end. Figure Ij shows a triangle pattern 3 for which the diodes are installed on two sides of the triangle, including around for simplicity, or if the maximum width of the whole pattern is greater than 70mm. Figure Ik shows a diffuser pattern that forms a frame 3 "having a rectangular internal contour 31" (or rounded corners) and an outer contour 32 "(or rounded corners). In this configuration, it is preferred to install the diodes around of the inner contour forming a preferably rectangular frame with a distance Dl (constant) between the nearest emitting face and the inner contour of at least 10mm and preferably less than or equal to 40mm.

As shown in Figure 1 'which is a rear view of a mirror 10' which integrates the pattern of the frame 3 ', the reflective surrounding structure 51b to 54b is a rectangular frame around the entire outer contour. In such a frame pattern pattern, the reflective surrounding structure may form, together with the bottom reflector (shown in dotted) and the facade glazing, an impermeable housing which does not include the support piece 51 and two carrier profiles mirror 81, 82 are used at the side edges of the pane.

Again, if the width W'1 of the frame pattern is greater than 70mm, similar diodes 42 are also fitted around the outer contour 32 'about the surrounding structure with a distance D 2 between the nearest emitting face and the inner contour being at least 10 mm and preferably less than or equal to 40 mm. Figure 11 (with two enlargements) shows how to position the diodes in the case of diffuser elements very close and yet with a very wide width to be surrounded by a single surrounding structure.

It is sought to define as many diffusing patterns as necessary, elongated and each engraved respectively in a rectangular (or square) region R, R1, R2 of width W1, W2, W3 of less than 230mm, preferably of 200mm, each region R, R1, R2 being spaced apart from the emitting faces of the distance D 1, D '1, D 1 of the longitudinal (preferably internal 31, 31', 31 ') edge of at least 10 mm and preferably less than or equal to 40 mm, if appropriate, of the distance D 2 (If W1 is greater than 70mm) from the other longitudinal (preferably outer, 32, 32 ', 32 ") edge of at least 10mm and preferably less than or equal to 40mm, and (for simplicity) if the case of the distances D 3, D 3, D 3 and D 4, D 4, D 4 of the side edges (preferably 33 to 34 ") of at least 10 mm and preferably less or equal to 40 mm.

The surrounding structures are not represented for clarity. Figure Im shows that a wall of the surrounding structure, such as a U-profile, can serve at the same time as a diode support part for two adjuvants. Figure In shows that for two adjacent patterns a same rectangular or square section profile can be used.

In Figures 1a to 1h, an analogous procedure is performed when one or the patterns are L-shaped to install by default the diodes.

In Figures 1a to 11 (except that when a profile of the surrounding structure does not include diodes (longitudinal edge, side edge), it is preferred that it be installed at the maximum near the edge of the diffuser pattern, for example, less than 10mm. Figure 2 schematically shows a partial cross-sectional view of an electroluminescent diode illuminating mirror 200 in a second embodiment of the invention.

Only the differences from the first embodiment will be described. The illuminating mirror 200 differs in particular from the mirror 100, first of all, by the width W! of the standard, greater than 70mm.

A single row of diodes 41 along the inner (or outer) edge 31 is not sufficient for the homogeneity of the illumination to normal. Another row of diodes 42 identical or similar to the first row is added at the base of the main reflector profile 52 thus along the outermost edge 32. In this case, we recall that the main reflector is preferably normal to the facade glazing for better homogeneity . The main radii F, F 'of the two groups 41, 42 therefore form a maximum angle of 5 ° with the facade pane.

Again, the distance D2 between the outer edge and the emitting face closest to the diode on the second PCB plate is at least 10mm. The maximum distance Dmax between the outer edge and each emitting face on the second PCB plate is less than 40mm. The first PCB board may be attached to the second PCB board 40 'between the lateral edge of the diffuser pattern and the side piece of the surrounding structure.

In fact, by way of simplification, the first and second PCB boards can be replaced by a single PCB board and the diodes are installed around the diffuser pattern 3, the PCB board being supported by the surrounding reflective structure 51 to 54. The diodes at the level or in the vicinity of the corners are at a distance of at least 10mm from the edge closest to the diffuser pattern: The bottom pane of this time, in a variation, is coated with a specular reflection layer 7 ', preferably a mirror layer , for example, a silver coating protected with a paint. In fact, one can select a bottom pane with a mirror region identical to the facade pane (except, in this case, for its size).

As an attachment option with respect to Figure 1, as shown in Figure 2a, the attachment frame 8, 81 to 84 lies in the central region of the mirror 200. Likewise, the outer edge of the diffuser pattern 31 may be closer to the segment 13 of the facade pane, typically less than 25mm considering the distance D2 and the thickness of the profile of the surrounding structure 52. The diffuser pattern 3 is formed here by five diffuser elements 3 of complex shape (rounds and fused rectangles) or optionally , non-geometric shape recorded in a rectangular region R as explained, which may serve to define D1, D2 and possibly D3 and D4, if appropriate. Figure 2 'schematically represents a rear side side view of a light emitting diode mirror 200' in a variation of the second embodiment of the invention.

Only the differences with respect to the second embodiment will be described. The illuminating mirror 200 'differs in particular from the mirror 200 by the first pattern forming a large L (thus, six sides) on one side and longitudinal edge of the facade pane 1 and another small L pattern, (hence six sides) on the other longitudinal side edge of the facade pane 1. Two surrounding L-structures are used: the first surrounding structure with six U-shaped profiles 51 to 56 joined with the sealant 63, such as silicone, therefore a profile per side or edge of the large diffuser pattern, the second surrounding structure with six U-shaped profiles 51a to 56a joined with the sealant 63, such as silicone, thereafter again a profile per side or edge of the small diffuser pattern.

A single pane 1 'is used, with the specular reflective layer 7' (or diffuse 7), to form the two background reflectors of the small and large diffuser pattern, which thus forms a frame, absent from the center of the mirror, for the (internal and external contour 13 'of the glazing 1 in dotted'). Such a glass pane 1 'may optionally be plástico plastic or polycarbonate. It is also possible to use for each surrounding structure an L-shaped pane, therefore, in the form of each diffuser pattern. Figure 3 schematically shows a partial cross-sectional view of an electroluminescent diode illuminating mirror 300 in a third embodiment of the invention.

Only the differences from the first embodiment will be described. The illuminating mirror 300 differs in particular from the mirror 100 by the size of the bottom reflector 1 'which extends over the central region and over the region of the second diffuser pattern (not shown). In other words, a single background reflector is used for the two diffuser patterns.

In addition, the four U-profiles forming the reflective surrounding structure of the first diffuser pattern are replaced by profiles 51 'to 54' as spacers, of rectangular or square closed section. For greater efficiency, the flank 5 'on the inner space side of the main reflector 52' is bordered by the outer edge 32 of the diffuser pattern or is less than 10 mm.

As shown in Figure 3a, each diffuser pattern 3 is formed by two strip diffusers 3i etched in a rectangular region R. In addition, the reflector box is a carton common to each diffuser pattern, rather than using a dedicated diffuser pattern, and also surrounds the power cable 91 and the transformer 93. To this end, the side profiles 53 'and 54' are enlarged. The diode support pieces 51 ', 51' and more central than the main reflectors 52 are not part of the waterproof case. The parts of the support 51 'and 51' a are not necessarily attached to the common carton.

As an option, a U-shaped profile (or H or Z or L, inclusive) can be used for the diode support piece 51 'or 51' a. Figure 4a schematically depicts a rear view of an electroluminescent diode illuminating mirror 400 in a fourth embodiment of the invention. Figure 4 is a partial side cross-sectional view from a longitudinal edge 131 of the facade pane 1. The diffuser pattern 3 engraved on a rectangular region R is in the form of six blisters (with a blister cut off at the end) and whose edge side edge 34 extends to the Z-shaped edge of the wide edge 34 of at most 2mm. For preferably the diffuser pattern 3 throughout its length, a non-erect profile is installed against the rear face 11, which is a metal (or reflective) clamp 54 "against or eventually attached to the rear face by a which is a white or preferably transparent silicone sealant 610 in the Z region. The single edge 54b, side of the bottom reflector 1 ', extends in relation to the diffuser pattern 3 and invariably secured by the double-face adhesive 62 The clamp has a thickness eP of 0.8mm, even of 1mm. The clamp 54 "is devoid of diodes (source of hot spots).

As an option, a plastic U-shaped plastic box (with a reflective layer on the rear side) is used, with a maximum thickness of 0,8 mm up to and including 1 mm, possibly with support piece 51 and main reflector 52 for a minimum contact width of 5mm on the rear face 11 with the adhesive 61, preferably double face. The same clamp and edge seal system may be used under a patterned edge of the other side edge (in addition); again clamp devoid of diodes and even realize the same clamp system and edge sealing over a longitudinal edge and the main reflector is not carrying diodes. The adhesive (double-sided) fastening 61 on three sides of the rear face or even on two sides is sufficient.

As an option, it is feasible to make a plastic crate with a reflective layer (external face) with fixing edges or hooking profiles, except on or on the shaped edges as described. Figure 5a schematically depicts a rear and partial view of an electroluminescent diode illuminating mirror 500 in a fifth embodiment of the invention. Figure 5 is a partial longitudinal cross-sectional view of this mirror 500.

In this configuration, the carton further includes three U-shaped profiles, for example, glued with the double-face adhesive 61 to the rear face of the facade pane 1 and below the mirror layer 2 and with the double-face adhesive 62 to the reflector of the bottom 1 '.

A fourth U-shaped straight profile 8 with a base 8a and two edges 8b as opposed to the inner space 14 (or optionally a rectangular or square section spacer-shaped, spacer-like profile), metal (optionally, of plastic or glass and with a reflective layer). This fourth profile has a contact width with the adhesive 61 'of at least 10mm for a satisfactory fixation of the mirror and a material thickness of at least 1.5mm and possibly a height H' greater than H. This profile 8 is not only useful for fixing to a wall (mobile, wall, etc.) by means of one or two securing apertures 80, but also for the surrounding structure, as a support part of the diodes on the face 8'a.

This fastening profile therefore supports across this straight wall 8'a the first PCB plate 40 with the diodes 41 along the longitudinal inner edge 31 of the diffuser pattern 3, for example three bubbles with a maximum width of 60mm and at a distance Dl of at least 12mm from the inner edge 31. The surface of this securing profile facing the segment 13 'of the reflector 1' is sealed by the addition of a "side" seal member, for example a silicone sealant seal 64 ' or double-sided adhesive 64. The profile borders the profiles 53 'and 54' through a silicone sealant 63.

Alternatively, and not cumulatively, the longitudinal outer profile (forming the main reflector) may be replaced by a mirror supporting profile having the same configuration. This is also possible in the case of a common box, in particular also to surround a second diffuser pattern. Figure 5a schematically represents a rear and partial view of an eletronic luminescent mirror 500 'in a variation of the fifth embodiment of the invention.

This mirror 500 'differs from the mirror 500 in that the securing profile 8 replaces not a support part of the first PCB plate, but a profile, forming part as a preferably longitudinal wall on the inner (or external optional) edge of the housing of the first PCB 40 board and power supply. Here, the profile of the diode carrier 51 ', for example, a square or rectangular section spacer is not necessarily contiguous or secured with an adhesive or seal to the other side profiles 53', 54 '. Figure 5 schematically shows a rear view of an electroluminescent diode illuminating mirror 500 "in a ninth embodiment of the invention.

This mirror differs from the mirror 500 in that each diffuser pattern 3 (central edge strip, which forms a "T", therefore with eight sides or edges) is surrounded by a PCB plate on seven profiles (of the spacer type with section rectangular or square side, joined with sealant 63 or separated by less than 5mm) and onto one of the profiles 81 or 82 of the mirror holder forming part of the securing profile 8 (four-piece frame 81 to 84 in the central region of the mirror) . Each of the profiles forms part of the surrounding structure of a diffuser pattern and contains the diodes for their diffuser pattern in a portion 810, 820 of the profile. Figure 6a schematically depicts a rear and partial view of an electroluminescent diode illuminating mirror 600 in a sixth embodiment of the invention. Figure 6 is a partial cross-sectional view of this mirror.

In this configuration, the reflective surrounding structure further includes three U-shaped profiles secured to the rear face of the facade pane 1 below the mirror layer 2, for example, glued with the double-face adhesive 61 and the bottom reflector 1 ' for example, with the double-sided adhesive 62.

A fourth rectangular profile 8 is U-shaped with a base 8a and two edges 8b as opposed to the inner space 14 (or, optionally, rectangular or square closed section profile) is between the bottom reflector 1 'and the window pane facade 1, but with different dimensions.

This profile 8 is preferably produced in metal or plastic or glass with reflective layer. This profile has a material thickness of at least 1.5mm, a contact width with the mirror layer by the double-face adhesive 61 'of at least 1mm and a contact width with the bottom reflector of at least 10mm.

This profile 8 contains, by means of a straight wall 8a of the base, the first PCB plate with the diodes 41 along the longitudinal inner edge 31 of the diffuser pattern 3, for example three rollers 3i with a maximum width of 65mm and at a minimum distance Dl of 10mm from the inner edge 31 of the diffuser pattern.

This profile 8 therefore serves not only for the surrounding structure, but also for attachment to a wall (furniture, wall, etc.). Likewise, this securing profile 8 includes two protruding (in this case, longitudinal) protruding ends 8c, 8d of the bottom reflector 1 on two opposite end edges below the mirror layer 2 at the periphery of the facade pane 1 and with artifacts for fixing, such as an aperture 80 or a double-sided adhesive.

As an alternative or in addition, the longitudinal outer profile (main reflector) can be replaced by a mirror supporting profile accompanying the same configuration, Figure 6 'a schematically represents a rear and partial view of an illuminating mirror of diodes eletroluminescent.es 600 'in a variation of the sixth embodiment of the invention.

This mirror 600 'differs from the mirror 600 in that the securing profile 8 replaces not a support part of the first PCB plate, but a profile, forming part as a wall preferably along the inner edge (or optionally the outer edge) of a common sealing box of the first PCB plate 40 and of the electrical power supply 93. In this case, the profile of the diode carrier 51 ', for example of rectangular section, is not necessarily contiguous or secured with an adhesive or sealing to the other lateral profiles 52 ', 53', 54 ', for example, of rectangular section. Figure 7 schematically shows a partial cross-sectional view of an illuminating mirror of electroluminescent diodes 700 in a seventh embodiment of the invention.

Only the differences from the first embodiment will be described. The illuminating mirror 700 differs in particular from the mirror 100 by the main reflector 52 'which is a profile (spacer and between the mirror layer 2 and the bottom reflector 1 ") of rectangular cross-section bordering the outer longitudinal edge 32. Figure 8 represents schematically a partial cross-sectional view of an electroluminescent diode illuminating mirror 800 in an eighth embodiment of the invention.

Only the differences from the first embodiment will be described. The illuminating mirror 800 differs from the mirror 100 by the choice of the surrounding frame assembly and the reflector. A plastic (PMMA, PC) container 50 is used wherein: the bottom, flat (or concave towards the inner space) coated with a reflective layer 7 (preferably diffuse reflection) on the outer face opposite the inner space forms part of the bottom reflector 1 "and four side walls or flanks 501, 502, 503, 504, normal to the facade glazing, coated with a reflective layer 7 (preferably of diffuse reflection) on the outer face opposite the inner space form part of the surrounding structure reflective.

More precisely, the crate does not have a simple U-shaped section, it further has an edge 50a directed to the inner space and provided with the double-face adhesive 61 over its entire perimeter. The inner space oriented edge is perpendicular to the side walls 501 to 504, and frames the diffuser pattern 3 without advancing on the diffuser pattern 3. The thickness of the crate is less than 5mm, for example 0.8mm. The edge may also be coated with a reflective layer (preferably diffuse reflection) on the outer face opposite the inner space and in contact with the double-face adhesive 61.

Such a crate may be made by molding, extruding the reflective layer 7 by depositing before or after forming.

As a fixing option, the edge of the frame (or a part of the edge of the frame) is external to the internal space, however, to the detriment of compactness, and the diffuser pattern of the edge of the facade pane is elongated. Figure 9 schematically shows a partial cross-sectional view of an illuminating mirror of electroluminescent diodes 900 in a ninth embodiment of the invention.

Only the differences from the eighth embodiment will be described. The illuminating mirror 900 differs from the mirror 800, first of all, by the shape of the crate and its fastening. A simple U-shaped crate with a thickness of approximately 1 mm is used. This crate is made of plastic, for example polycarbonate or ΡΜΜΆ, with a reflective layer 7 as opposed to the inner space 14. The bottom is flat (or, optionally, concave towards the inner space). The thickness of the crate is less than 5mm, for example, 3mm,

To be secured, two latching profiles 511, 512, which are L-brackets, each having: a portion against a side wall 501, 502 of the surrounding structure and along a longitudinal edge 31, 32 of the pattern diffuser 3 and the inner space side 14, a 90 ° part against the mirror layer 2 always in the inner space and without passing the edge 31, 32.

Optionally, four fastening clamps are used on all four flanks. The fastening is made by means of screws 6e. Two diode bars 41, 42 are attached with a double-sided adhesive 6 on the hooking profiles 511, 512 along the edges 31, 32. The case 50 is fixed, for example, to a wall, a wall of furniture , by means of fastening plates 8 'with fastening lugs, metal sheets bonded, for example, with the same double-face adhesive 6' on the layer 7 'or drilling with screws. Figure 9 'schematically shows a partial cross-sectional view of an illuminating mirror of electroluminescent diodes 900' in a variation of the ninth embodiment of the invention.

Only the differences from the ninth embodiment will be described. The illuminating mirror 900 'differs from the mirror 900, first of all, by its external fixation to the inner space by the clamps 511, 512 external to the crate. Optionally, four clamps (one clamp per carton wall) are used. Figure 9 schematically depicts a partial cross-sectional view of a diode illuminating mirror eletroluminescent 900 in further variation of the ninth embodiment of the invention.

Only the differences from the ninth embodiment will be described. The illuminating mirror 900 "differs from the mirror 900 as it extends across substantially the entire surface of the facade pane 1 to eventually encircle the power supply and even other diffuser patterns (not shown). Optical measurements are performed on the illuminating mirrors with four reflector architectures to evaluate the efficiency and homogeneity of luminance to normal.

Examples Ex1 and Ex2 are examples according to the invention. Examples Exlcom and Ex2comp are comparative examples made by the Applicant.

For all four examples, the illuminating mirror includes a facade pane with a mirror layer, a diffuser pattern, a reflective surrounding structure and diodes on a PCB board as already described with respect to Example 1B.

More precisely, in all four examples, the diodes consist of the product designated SMD3528 of the company ILLUSION LED Limited with color temperature 32Q0K. The efficiency of the PCB bar with the diodes is 80 lmúw. For the diodes, colorimetric variations of + ú- 0.005 in X and Y of the CIE color diagram 1931 are preferably selected. Rl is, like TL, defined in EN410. Measurements were performed under illuminant D65 with a Konica Minolta CM-3700d spectrophotometer.

In all four examples, the facade glazing is a Planilux 4mm pane of the Applicant company covered on its back by a layer with at least 50nm of silver with a protective coating. The silver coating and its shielding were sandblasted to form the diffuser pattern which provides a 95% haze and a TL of approximately 70%. This is the product Miralite REVOLUTION, treated with sandblast, of the company Applicant.

In example Exl, the pane of the bottom reflector is provided with a diffuse reflective layer which is on its outer main face, therefore, as opposed to the inner space. More precisely, it is the product Planilaque white of the company Applicant formed by a Planilux glass pane of 4mm and white lacquer.

In Example Ex2, the pane of the bottom reflector is provided with a specular reflective layer which is on the outer face, therefore, as opposed to the inner space. More precisely, this is the product Miralite REVOLUTION, the company Applicant formed by a Planilux 4mm pane coated on its external face with a layer of at least 50nm silver with a protective paint.

In the comparative example Excompl, the bottom reflector pane is provided with a diffuse reflective layer which is on the inner face, therefore, the inner space side. More precisely, it is the white Planilaque product formed by a Planilux 4mm pane and white lacquer.

In the other comparative example Excomp2, the bottom reflector is an aluminum plate coated with a white diffusing paint. Table 2 below shows comparative optical measurements of the carton using the four background reflectors cited. Δ luminance indicates the luminance deviation to normal translating the degree of homogeneity of illumination from one longitudinal edge to the other.

Table 2

The flow and efficiency measurement protocol is shown below, for each example. The mirror is initially attached to the center of an integrated sphere to measure the luminous flux and the color temperature of the light extracted from the diffuser pattern. From the luminous flux measured, one can calculate the luminous efficiency of the mirror.

Then the mirror is positioned under a Lumicam camera to measure the luminance to normal at each point of the pattern and determine the homogeneity of the illumination.

The reflectors on the outer face of the glass pane (examples 1 and 2) allow a more homogeneous illumination of the diffusion region. One plausible explanation is that a part of the light reflected by the lacquer or the mirror is guided inside the glass, making the illumination more homogeneous. The measured RL value of Example 1 is not significant, because it does not take into account the light propagating in the segment. The reflector with the diffuser layer on the outer face (Example 1) additionally allows preserving a color temperature close to that of the diodes (about 32KD) as opposed to the mirror reflector on the rear face. The light transmission TL measured on the outside face to the inner space is low enough not to lose light. The surface of the inner space side of the glass sheet may be smooth as here or, alternatively, textured or with a diffuser layer.
