Description

2953703 LIGHTING MIRROR

The invention relates to the field of mirrors and in particular illuminating mirrors. The most common models of illuminating mirror use fluorescent tubes positioned at the back of the mirror and diffusing their light through sandblasted windows.

However, these devices require regular maintenance to replace defective fluorescent tubes. In addition, fluorescent tubes contain mercury, heavy metal pollutant (the tubes are often thrown out of any recirculation circuit) and dangerous (for example during the breakage of a tube). In addition, the illumination provided is relatively aggressive.

To overcome the drawbacks of fluorescent tubes, the use of light-emitting diodes (LEDs or LEDs), which have the advantages of low power consumption and longevity, is developing more and more in lighting applications. functional.

EP 1 834 551 discloses an illuminating mirror whose light sources are LEDs. Such a mirror is designed by the laminated assembly of a reflective glass sheet on the rear face fulfilling the mirror function, a median clear structure for supporting the LEDs, and a means for dispersing the light opposite front consisting of a clear glass sheet whose surface is sandblasted opposite the LEDs. The LEDs are thus laminated between the rear glass sheet and the front glass, and distributed around a transparent window formed in the clear glass facade and constituting the mirror as such. The sandy surface of dispersion of the light rays of the glass facade, towards which the LEDs illuminate, ensures a distribution of the density of the homogeneous light radiation over the entire illuminating surface and all around the mirror.

However, such a mirror is complicated to produce, or even too bulky for some applications. The object of the invention is to propose a solution that is still different from those advanced in the prior art, by providing a mirror that is compatible with industrial requirements (ease and speed of production, reliability, etc.), preferably compact. while maintaining lighting that is durable over time and evenly distributed without glare.

The illuminating mirror according to the invention comprises: a glass sheet with main faces, respectively called rear and front faces, and a wafer, and having a reflective surface on the rear face to ensure the mirror function, - diodes electroluminescent or LED providing the illumination function, - diffusion means ensuring the extraction of light, the light exiting through the front face, 25 - at least one section associated with the glass sheet and arranged against the edge of the glass sheet, the section carrying the LEDs, the LED light being injected by the edge of the glass sheet, the section having an extension portion, coplanar with the front face, and the glass sheet having 30 on the front face, and at the limit of at least one of the peripheral edges of said front face, a recess in which is accommodated and made integral, preferably by gluing, the extension part profile for fixing said profile to the glass sheet.

The mirror function is obtained by the reflecting surface which can have a light reflection RL from at least 50%, preferably even at least 70%, and even at least 80%.

The reduced thickness generated by such a device for which the LEDs are not arranged at the rear of the mirror, but on its edge, provides an extremely varied integration offer in everyday life, such as in bathrooms. washrooms, on wall walls, or in association with all types of furniture, in particular sliding or swiveling mirrored doors of glass cabinets or cupboards.

Its small thickness allows to attach to all types of surface without requiring the provision of a useful clearance on the back to provide lighting. Nevertheless, the thickness of the glass sheet could be greater in order to meet purely aesthetic and design requirements.

The robustness of the LEDs also makes these mirrors particularly interesting in intensive uses such as in public transport such as trains, planes, coaches, pleasure boats.

The volume of the recess incorporating the extension part of the profile is adapted specifically to the insertion dimensions of this extension part so that the association of the profile with the glass sheet 30 causes a coplanarity of the glass sheet. and the profile on the front, thus providing an aesthetically pleasing mirror and particularly providing ease of cleaning, which is particularly important when such mirrors are used in intensive applications such as public transport washrooms (trains, planes, coaches ...) or in hotels and other business premises.

The depth of the recess is naturally adapted to the thickness of the material constituting the profile and of a nature to not weaken the glass. For example, the depth is less than or equal to 1.5 mm for a glass of 4 mm; the depth is less than or equal to 3 mm for a 6 mm glass.

The width of the recess (dimension extending from the edge of the glass toward the opposite edge) is set to properly secure the profile to the glass sheet while providing a surface of the front face of the totally flat mirror. , and in a complementary way to dissimulate by its opacity the alternation of the luminous and dark points to the right and in immediate proximity of the LEDs in operation. This width is for example at least 10 mm. The extension portion of the profile accommodating in the recess extends over a width of the front face with respect to the edge of the glass sheet of at least 10 mm, and preferably less than 20 mm.

Preferably, to minimize its thickness and simplify its manufacture, the mirror is monolithic; it comprises a single sheet of glass, preferably less than or equal to 8 mm thick, or even less than or equal to 6 mm. The profile may be of any shape so as to mask the diodes: in U, in J, in C, in L, etc.

Preferably the profile forms an entourage of the diodes, to provide them with better protection. Thus, preferably, there is no hole in the edge of the glass to accommodate the diodes.

And for a simplicity of realization and mounting, the profile has a preferably J-shaped section. In a particular form, the profile comprises opposite the extension part, a return arranged in abutment against the edge of the glass sheet.

According to one characteristic, the profile extends or is associated with other profiles over the entire periphery of the mirror and forms a peripheral frame integral with the periphery of the glass sheet, and the recess is formed preferably on the entire periphery of the front face.

The profile is typically between 0.5 and 1.5 mm thick. A double-sided adhesive for its attachment to the glass is of the order of 0.4 mm.

The protruding width of the profile (width beyond the edge of the glass and opposite direction to the glass sheet) is preferably less than 2 cm, more preferably less than or equal to 1 cm.

The profile may be formed of an opaque and thermally conductive material, in particular of metal type such as aluminum.

It is conceivable to manufacture on the same principle a double-sided mirror, in particular to form a partition, the glass sheet of the mirror described above is then secured, in particular by a lamination interlayer, another glass sheet and, the other glass sheet having principal faces, one said integral because joined to the first sheet of glass and the other said output, and one wafer, with a reflective surface on the integral face to ensure the function of mirror, - other light-emitting diodes or LEDs being arranged to provide the lighting function, - other diffusion means being arranged to ensure the extraction of light, the light exiting through the exit face opposite to the integral side, and at least one other section associated with the other glass sheet and arranged against the edge of the glass sheet, the other section carrying the other LEDs, the light being injected by the wafer of the other glass sheet, and - said other section having an extension part, coplanar with the exit face, and the glass sheet having on the exit face, and at the limit of at least one peripheral edges of said outlet face, a recess in which is accommodated and made integral, preferably by gluing, the extension portion of said other profile for fixing said other profile to the other glass sheet.

The diodes can be simple chips or with low volume encapsulation. It is not necessary to use lenses. The width of LED support is preferably less than 1 cm.

The LEDs are preferably lateral emitting faces, said face facing the edge of the glass sheet, and the LEDs are preferably arranged on a part of the profile which is coplanar with the front face of the mirror and in a zone protruding from the edge of the glass sheet

Advantageously, the LEDs are arranged on at least one support bar secured to the profile. The bar or bars are preferably fixed by gluing with a glue or a double-sided adhesive thermally conductive, to promote the dissipation of heat generated by the LEDs.

Preferably, the bar or strips are fixed by bonding a double-face thermally conductive adhesive to a flat interface piece, advantageously metallic, itself fixed by gluing on the profile such as with a curable glue not to provide immediate solidarity. Such a fastening allows a relative positioning of the bar of small dimensions in a precise manner on the part of the profile coplanar with the front glass, in particular in the case of a semi-closed profile having a return to form an entourage.

The diffusion means are present in front of the glass sheet, opposite the reflective layer, and formed either by a surface treatment of the sandblasting type glass sheet, acid attack, enamel or paste deposit diffusing, or by a treatment in the mass of laser engraving type glass.

The laser etching in the thickness of the glass may be preferred as diffusion means in planes extending parallel to the main faces of the glass sheet. Indeed this type of treatment being in the mass, it is not sensitive to soiling and the glass is easy to clean. The scattering means are arranged at the desired locations of light extraction. It is thus possible to draw the path of the light on the surface of the mirror by diffusing it through diffusing surfaces with defined areas and contours, according to for example geometric patterns or even text.

The total surface of the diffusing means may occupy for example less than 50% of the total area, or even 20% or less.

It may furthermore be preferred to place the diffusing means (in volume or on the surface) at the periphery, and thus have a central mirror zone.

For example, one or more functional light zones (visible zone, outside the zone of hot spots masked by the profile) are chosen, for example at the periphery of the glazing, of identical or distinct intensities. These light areas may be solid or discontinuous, by interruption (s) of the diffusion means in the area of the light zone in play (to create patterns etc).

It is possible to form, preferably on two opposite edges, two (rectangular) strips, for example of a width of 5 cm or more, for example of the order of 10 cm.

It is also possible to form a light ring (round, oval, ellipsoidal, etc.), for example with a center corresponding substantially to the center of the glazing, and / or of the largest possible outer diameter, and / or for example having a width (difference between external diameter and internal diameter) of 5 cm or more, for example of the order of 10 cm.

The light transmission of the glass sheet (front side side) of the invention may be greater than or equal to 80%, or even 85% or 90%. The glass can be extraclear; reference WO04 / 025334 may be referred to for the composition of an extraclear glass. In particular, it is possible to choose a silicosodocalcic glass with less than 0.05% Fe III or Fe 2 O 3. Examples include Saint-Gobain's Diamant® glass, Saint-Gobain's Albarino® glass (textured or smooth), Pilkington's OptiWHITE® glass, and Schott's B270® glass. The present invention is now described by way of purely illustrative and non-limiting examples of the scope of the invention, and from the accompanying drawings, in which: FIG. 1 shows a cross-sectional view of the mirror Illuminating of the invention; Figure 2 is a longitudinal and front sectional view of the mirror according to the invention; Figures 3a to 3c illustrate cross-sectional views of a mirror according to the invention according to variants of profile shapes; FIG. 4 is a cross-sectional view of a mirror according to an example of mounting the LEDs in the profile; Figure 5 is a cross-sectional view of a mirror according to the invention double-sided.

The figures are diagrammatic and are not scaled for ease of reading.

The illuminating mirror 1 of the invention illustrated in FIGS. 1 and 2 comprises a transparent glass sheet 10, at least one profile 2 arranged laterally to the glass sheet, and light-emitting diodes 3 arranged inside the profile. The arrangement of the diodes at the edge of the glass sheet produces light rays introduced via the wafer 14 of the glass sheet, as schematically represented by the arrows.

The transparent glass sheet 10 is for example derived from a so-called clear glass such as PLANILUX® glass sold by the company SAINTGOBAIN GLASS, or preferably a glass called extra-clear under the name DIAMANT® marketed by the company SAINT- GOBAIN GLASS.

The transparent glass sheet 10 has two opposite main faces, a rear face 11 and a front face 12 intended to be vis-à-vis the observer looking in the mirror.

The rear face 11 is reflective to provide the mirror function; it is usually covered with a silver-based layer 13 such as the SGG MIRALITE product from SAINT GOBAIN GLASS, itself coated with an oxidation protection paint (not shown), or alternatively with chromium base such as the SGG MIRASTAR® product from SAINT GOBAIN GLASS.

The front face 12 is locally provided with diffusion means or subsequently diffusing means 16 for extracting the light towards the outside of the glass sheet in which the light emitted by the LEDs is trapped. It is not imperative that at right diffusing means 16 the reflective layer 13 is present, however the latter implementation would make the manufacturing process more complex.

With this concept, the illuminating mirror thus produced has a relatively thin thickness slightly different from the corresponding glass sheet, for example of the order of 6 mm, or even 4 mm, to facilitate the arrangement of the illuminating mirror in its final destination.

The glass sheet is associated with its section 14 to the profile 2. At the front face 12 of the mirror, the glass sheet comprises in its thickness a recess forming a recess 15 for receiving an extension portion 20a of the profile. The recess 15 is made by any known glass forming means such as milling or grinding. This recess extends from the edge of the glass over a limited width and depth.

The section 2 houses the diodes 3 which provide a light radiation of direction substantially parallel to the faces 11 and 12 of the glass sheet. The light is introduced through the edge of the glass sheet, the glass becomes, according to its thickness, a true guide of light. For example, side emitting-face LEDs are chosen which are positioned on the core or on the return of the profile. As illustrated in FIG. 1, the profile 2 has a generally shaped section, by way of a preferred example, with straight edges. Thus, the profile comprises a core 20, a flange 21 perpendicular and connected to one of the distal ends of the core, and a return 22 connected to the flange 21 to the opposite of the core 20 and s'. extending parallel to the core and preferably of smaller dimension. The return 22 preferably abuts the edge of the glass and therefore does not extend on the rear face of the glass to avoid unnecessary excess thickness especially in wall applications. 3010 The shape given to the profile household a longitudinal cavity 23 delimited by its bottom and its walls respectively constituted by the wing 21, and the core 20 and the return 22. The profile is not closed on itself, it has parallel and opposite the cavity 23 a longitudinal opening 24 for the injection of light emitted by the LEDs in the wafer 14.

Several shapes of profiles other than that of Figure 1 are conceivable. Figures 3a to 3d are non-limiting examples. Figure 3a shows a J-shaped section section as in Figure 1 but whose profile of the flange 22 is curved. For example, the profile is flat and foldable during installation.

FIG. 3b illustrates a C-shaped section whose return 22 extends beyond the edge of the glass sheet by covering a portion of the rear face of the mirror, the return 22 being secured by gluing. The rear face may advantageously be provided with a recess 22a for accommodating the return 22 in order to avoid an extra thickness on the rear face of the mirror. FIG. 3c shows an L section section with only a web 20 and a wing 21, the glass sheet having been recessed in its thickness to make room for a cavity corresponding to the housing 23 of the LEDs.

The profile consists of an opaque material and advantageously heat conductor to ensure an outward evacuation of the calories generated by the diodes during their operation. By way of example, the profile is made of aluminum and obtained in extruded form.

To provide the desired aesthetic to the mirror, the profile can be lacquered, painted, decorated, anodized.

The profile extends partially (as shown in Figure 2) or could walk over the entire periphery of the glass sheet in the manner of a frame. It may be unique and suitably shaped to follow the outline of the glass sheet, particularly when the mirror has a curved outline. Alternatively, several profiles may be provided to correspond to each of the sides of the glass sheet and to which they are associated while being abutted with each other at the corners of the glass sheet.

When the profile is limited to a portion of the periphery of the glass sheet, its distal and lateral ends (transverse to the opening 24) are closed.

The shape of the profile, its dimensions and its cooperation with the glass sheet are established to allow attachment of said profile to the glass sheet such that: the free end portion 20a is housed in the recess 15 of the sheet of glass. glass, the core 20 of the profile thus extending in front of the mirror being coplanar with the front face 12 of the glass sheet; the core 20 has a length suitable for providing a suitable extension of the profile in front of the mirror; - The profile is of total thickness (not to be confused with the thickness of the profile material, for example 1 mm) identical to that of the glass sheet, for example 4 or 6 mm.

By way of example, the thickness of the recess according to the transverse dimension of the main faces of the glass sheet is 1.5 mm for a glass sheet thickness of 4 mm. The width of the recess, dimension extending from the edge of the glass sheet to the opposite edge, is in particular at least 10 mm.

Each of the geometric features above have advantages.

Thus, the arrangement of the free end portion 20a in the extension of the face 12 of the glass sheet makes it possible to obtain a planar mirror facade without discontinuity and difference in level between the glass sheet and the profile, facilitating cleaning the mirror with a squeegee or cloth over the whole surface of the mirror without any risk of retention of cleaning fluid, dust or dirt.

In addition, the adapted length of the extension portion or portion 20a of the profile, preferably at least 10 mm, corresponding to the width of the recess 15, makes it possible to mask the hot spots (zones of immediate proximity of the LEDs, bright and dark) generated by the LEDs. In this way, the source of the light emission is advantageously not detectable for an observer, giving a soft light irradiation rendering over the entire surface of the mirror.

Finally, with a total thickness equivalent to that of the glass sheet, the profile when it extends in particular over the entire periphery of the glass sheet leads to a frame in perfect prolongation with the lines of the glass sheet giving a uniform and monobloc appearance to the mirror.

The profile is fixed by fastening the extension part 20a in the recess 15, preferably by glueing the adhesive or double-sided adhesive type using a material compatible with the glass and the glass. aluminum. An adhesive seal is also deposited between the edge of the glass sheet and the free end 22a of the return 22 of the profile.

As expressed above and visible in FIGS. 1 and 2, the profile 2 houses the LEDs 3. The profile is dimensioned in relation to this LED reception function. It has in particular a projecting width of the glass sheet (dimension extending parallel to the main faces of the glass sheet) of 7.5 mm.

The LEDs are, for example, arranged in a known manner on one or more printed circuit boards in the form of strips 4 which are attached in the cavity 23, preferably on the core 20.

The strips are preferably fixed by means of a thermally conductive adhesive or double-sided adhesive, such as, for example, the 3M® product of reference 8940. This glue or this adhesive contributes to the dissipation of the calories towards the profile which in turn, thanks to its conductive material, the evacuates to the outside, the calories being generated at the welds of the LEDs on the bars 4 during operation of said LEDs. The thickness of a double-sided adhesive is, for example, 0.4 mm.

The support 4 LEDs, such as one or bars can be arranged in different ways in the housing 23 of the profile. Figures 3b and 3c illustrate an embodiment, the support 4 being mounted by gluing on the core 20 of the profile.

FIG. 4 is another exemplary embodiment for which the support 4 is mounted 3o parallel to the edge of the glazing while being held by two opposite edges in respectively two grooves 25 and 26 opposite and present respectively in the core 20 of the profile and its 22. This example is particularly suitable for a glass sheet at least 6 mm thick.

Each strip, independently of the arrangement on the core or the return of the profile, may preferably be pre-mounted on a part 6 (illustrated for example in FIG. 3c) forming a flat support or flat interface, of small thickness ( for example less than 2 mm), made of a material also good thermal conductor, in particular metal, and then inserted and glued into the profile by a double-sided adhesive. A double-sided adhesive (thus of calibrated thickness) is used between the interface and the strip to provide a constant thickness in order to optimize the heat transfer and to ensure the absence of electrical contact between the printed circuit boards. the bar and the profile that could cause some LEDs to malfunction.

The attachment of the interface on the core of the profile 2 is then done by means of a conventional adhesive (crosslinkable etc.), the shearing stresses during the installation is not a problem as long as this glue is not not hardened.

The assembly of the LED strip with the support interface via a double-sided adhesive and a curable adhesive (which does not provide an immediate fixation) is preferred because it allows a relative positioning of the bar of small precise dimensions on the surface. soul, especially in a profile with a wing and a return.

Preferably, a single flat support interface is used for all the bars, at least along a given edge of the glass, in particular to proceed to the bar array connections without discomfort.

Depending on the desired lighting, the LEDs are distributed regularly or not along the profile. In addition, when the profile forms a frame to ensure a harmonious aesthetic assembly, LEDs can in particular be distributed only punctually and not on the entire perimeter of the mirror. In order to ensure the extraction of the light from the mirror, the front face 12 comprises the diffusing means 16 (FIG. 1) which can be arranged on the external side of the sheet in contact with the external environment, or in the thickness of the glass. These means are, for example, obtained by surface treatment of the glass of the sandblasting type, acid etching, enamel or diffusing paste coating, etc., or by treatment in the mass of the laser engraving type glass.

These diffusing means 16, for example in the form of strips, are arranged at the desired locations of extraction of the light, in particular peripheral to the glass sheet.

The combination of a lighting by diodes positioned on the wafer, and diffusing means can also allow to obtain a very bright lighting without dazzling. The normal luminance in each functional visible light zone (outside the hot spot zone) is preferably less than 2000 cd / m2, more preferably less than or equal to 1000 cd / m2.

The association of the LEDs is achieved by means of a support profile housing the LEDs, made integral with the glass sheet, facing the edge of the glass sheet. The shape of the profile and its attachment to the glass sheet can be configured in various ways, the embodiment described above is given here by way of non-limiting example.

The device of the invention can in particular be doubled so as to constitute a double-sided mirror, useful for example in a partition application. Figure 5 illustrates this embodiment.

A first glass sheet 10 is laminated with another glass sheet 10 'by means of a spacer 5. A profile 2 is associated with the glass sheet 10, while another profile 2' is associated with the other glass sheet and LED door 3 '. The references relating to the glass sheet 10 'and the other section 2' are similar to the first sheet 10 and the section 2 described above. The mirror reflecting layers 13 and 13 'are on the rear faces here, laminating faces 11 and 11'. The LEDs 3 and 3 'are preferably with a lateral emitting face, facing the edge of the sheet and fixed on the webs 20, 20' of the profiles.
