Description

LIGHT MODULE WITH PATTERNS AND IRREGULAR PRINTING

The invention relates to the field of lighting and light signaling for motor vehicles.

With the development of the use of light sources of the light-emitting diode (LED) type, it is known to provide a light signaling module, such as a rear light of a motor vehicle, with a screen forming a window of said module and having a series of zones capable of being backlit by light sources and this selectively. Such a construction makes it possible to produce variable illuminated surfaces. When the light module is completely off, the zones are potentially visible due to the fact that the screen or glass is translucent and the borders between the zones are opaque.

A regular appearance of the module screen, from an external point of view, is undesirable on a motor vehicle, in particular because of the curved and complex shapes of the contours of rear lights. In fact, the use of a regular geometric pattern, such as a square, will generate staircase profiles along curved or inclined edges, particularly unsightly. In addition, a regular geometric pattern is not suitable for forming complex images like certain pictograms. For example, it is difficult to make a circle with a square pattern, unless a particularly small pattern size is provided, which increases the complexity and the cost of the light module.

The aim of the invention is to overcome at least one of the drawbacks of the above-mentioned state of the art. More particularly, the invention aims to propose an interesting solution for the luminous display of pictograms on a motor vehicle, in particular at the rear of the vehicle.

The subject of the invention is a light module for a motor vehicle, comprising a screen with adjacent light areas in a regular pattern, said areas being light on command and individually; remarkable in that the light areas are arranged so as to form a basic repeating pattern; and the zones forming each basic pattern are adjacent in a main direction and in a transverse direction not perpendicular to said main direction.

The light zones are configured to light along an optical axis of the module, the main and transverse directions are advantageously in a plane perpendicular to the optical axis.

Advantageously, the transverse direction can have an inclination which varies along the regular pattern of the light zones in the main direction.

Advantageously, the main and transverse directions form an angle between 95 ° and 105 °. In other words, the transverse direction is inclined at an angle between 5 ° and 15 ° relative to a vertical direction when the main direction is horizontal, when the module is in the mounting position on the vehicle.

According to an advantageous embodiment of the invention, the main direction is horizontal when the module is in the mounting position on the vehicle.

According to an advantageous embodiment of the invention, the light zones forming each basic pattern are polygonal and comprise at least a first light zone with a first side extending in the horizontal direction and a second adjacent side extending in the transverse direction .

According to an advantageous embodiment of the invention, for each basic pattern, the second side of the first light area forms with the first side of said area an interior angle of between 95 ° and 105 °.

According to an advantageous embodiment of the invention, each basic pattern comprises, in addition to the first light area, a second light area and a third light area, said areas each having two adjacent sides parallel to two sides, respectively, of the other of said areas.

Advantageously, two adjacent and parallel sides of the second and third light zones extend in a direction other than the directions of the first and second sides of the first light zone, said direction being bi-secant from the angle formed by said directions.

According to an advantageous embodiment of the invention, the polygonal shape of each of the light areas is a pentagon.

According to an advantageous embodiment of the invention, each basic pattern has a hexagon shape.

According to an advantageous embodiment of the invention, the hexagon shape of each basic pattern comprises three non-adjacent sides formed, each by two sides aligned with two light zones of said pattern.

According to an advantageous embodiment of the invention, the basic patterns are adjacent to each other at each of the sides of each of said patterns. It is understood that this does not apply to the basic patterns located along the end edges of the screen. In other words, it applies to basic patterns surrounded by other basic patterns.

According to an advantageous embodiment of the invention, all the basic patterns have the same orientation.

According to an advantageous embodiment of the invention, the basic patterns progressively have opposite directions at 180 °. These basic patterns can also be symmetrical alternately.

According to an advantageous embodiment of the invention, the basic patterns form super patterns repeating step by step with the same orientation.

According to an advantageous embodiment of the invention, each super pattern comprises at least two basic patterns adjacent to one side of each of said patterns and having opposite orientations at 180 °.

According to an advantageous embodiment of the invention, the two basic patterns of each super pattern are surrounded by light zones identical to the light zones forming the basic pattern.

According to an advantageous embodiment of the invention, each super pattern comprises at least four adjacent base patterns step by step so as to form an S-profile.

According to an advantageous embodiment of the invention, each super motif comprises a basic motif surrounded by light zones identical to the luminous zones forming the basic motif.

According to an advantageous embodiment of the invention, each super motif has a hexagon shape.

According to an advantageous embodiment of the invention, the screen comprises a central portion extending in a horizontal main direction, when the module is in the mounting position on the vehicle, and two lateral portions intended to be on either side of the central portion.

According to an advantageous embodiment of the invention, the central portion has two lateral edges intended to be adjacent to the lateral portions, each of said edges being parallel to the second side of the first light zones forming the basic patterns located along said edge.

According to an advantageous embodiment of the invention, the central portion of the screen is configured to be fixed on a rear trunk lid of the vehicle and the side portions of said screen are configured to be fixed on the rear fenders of said vehicle, adjacent to said central portion.

According to an advantageous embodiment of the invention, the second sides of the first light zones forming the basic patterns adjacent to and on either side of a median transverse axis of the central portion have opposite and symmetrical orientations by report to said axis.

According to an advantageous embodiment of the invention, the module comprises light sources configured to individually illuminate each of the light areas, and a control unit for said sources, configured to illuminate said areas so as to form one or more pictograms. The pictograms include at least the following elements: horizontal line, essentially vertical line, arrow, point, ring, triangle.

Advantageously, the light sources are configured to produce white or colored light, such as for example red, advantageously with different intensity levels. They can be multicolored, that is to say able to selectively produce light of different colors.

The invention can also relate to a motor vehicle comprising one or more light modules according to the invention.

The measures of the invention are advantageous in that they make it possible to achieve the luminous display of pictograms of various shapes, and this in an economical manner, in particular without requiring an imager of the liquid crystal screen type and while conferring, on an outside observer and in the off state, a generally irregular appearance or appearance. Such a look provides an attractive aesthetic and avoids possible false interpretations in the event of unexpected light reflection on the screen. The screen, by its size, allows the display and optionally the animation of explicit pictograms. Inclining, with respect to the vertical, one side of one of the light zones forming the basic pattern, makes it possible to provide a direction of propagation of the basic patterns and of the light zones which corresponds to the border between a central part of the screen and the side parts.

Figure 1 is a front view of a light module according to the invention. The light module 2 is in this case a rear light of a motor vehicle. It includes a central portion 4 with a central portion 6 of the screen visible from the outside and two lateral portions 8 with side screen portions 10 also visible from the outside. The light module 2 also includes respective boxes for the central portion 4 and the side portions 8, these boxes being however not visible because located at the rear, according to the representation in FIG. 1, screen portions 4 and 10. Light sources, also not visible and advantageously of the electroluminescence diode (LED) type, are provided at the rear of the screen portions 4 and 10, in order to backlight them. More particularly, the light sources can be organic light-emitting diodes or DELO, usually designated by the acronym OLED, for "Organic Light-Emitting Diode". Light sources can emit white light or even color light, such as red. They can also be of the multicolored type, that is to say capable of emitting light with different colors depending on the electrical control signal. Also the light sources are configured to illuminate according to different intensity values.

In FIG. 1, it can be observed that the central portion 4 of the module 2 is fixed to a rear trunk flap 12 of the vehicle, while the lateral portions 8 are fixed to the rear fenders 14. More particularly, observe that the central portion 4 extends in a main horizontal direction, in this case over the entire width of the rear boot flap 12. It is also observed that the lateral portions 8 are adjacent to the central portion 4 along the lateral edges transverse to the horizontal direction and inclined to a vertical direction. In other words, when the rear boot flap 12 is closed, the central portion 6 and the lateral portions 10 of the screen of the module 2 form a generally continuous surface with however two interruptions along the inclined lateral edges. This surface has a multitude of light zones capable of being individually controlled in order to be able to form luminous pictograms, these pictograms being able to be dynamic, that is to say being variable in time by generating a movement on the screen, and being able to also cross the two interruptions at the lateral edges forming the discontinuities of the screen surface. It can be seen in FIG. 1 that the light zones are such that they have, in the off state, a generally irregular appearance. As will be detailed below, these light zones however make it possible to produce aesthetic pictograms, in particular across the border between the lateral portions 8 and the central portion 4.

Figure 2 is a detail view of a left part of the light module 2 of Figure

1. The principle of formation of the light zones is illustrated there. The light zones are constructed so as to form a repeating basic pattern 16, thus providing regularity in the light zones, necessary in order to be able to produce light forms of the same nature and definition over the entire extent of the screen 6 and 10 This basic pattern must moreover allow a harmonious transition to be made across the border between the central portion 6 and the lateral portions 10. For this purpose, the basic pattern 16 is repeated along the horizontal direction and has a geometry aligned with the inclined transverse direction. It can indeed be observed in FIG. 2 that the basic patterns 16 are also repeated along this direction. In this case the basic pattern 16 is a polygon, more particularly a hexagon whose opposite sides have the same length and, therefore, are parallel. However, it is not a regular hexagon because, if that were the case, its juxtaposition in two transverse directions would be in two perpendicular directions.

Still with reference to FIG. 2, in order to impart a certain resolution to the screen 6 and 10, and also in order to impart an irregular appearance, the basic pattern 16 is cut out into several light zones 18, 20 and 22, in l occurrence in three zones. We also observe that each of these zones 18, 20 and 22 is a pentagon. The cutting is in this case along three medians on three non-adjacent sides, then forming three distinct and different zones. Each of the pentagons includes one of the three remaining sides of the hexagon not cut by the midlines. In other words, each of the three non-adjacent sides of the hexagon cut by the medians is formed by two aligned sides of two of the three light areas 18, 20 and 22.

With reference to FIG. 3 showing three patterns of hexagonal bases juxtaposed in two transverse directions, the geometry of the basic pattern can be observed with respect to the horizontal direction and the transverse direction. We observe that the hexagon includes two pairs of vertices aligned with the horizontal and two other pairs of vertices aligned with the transverse direction. More specifically, it can be observed that three vertices belonging to two adjacent sides participate in both the horizontal and transverse directions.

FIG. 4 is a detailed representation of the basic pattern 16 and of the light zones 18, 20 and 22. It is observed that two of the three medians of the three non-adjacent sides 16.1, 16.2 and 16.3 of the hexagon correspond to the horizontal directions H and transverse T. The remaining sides are the sides 16.4, 16.5 and 16.6. The third median corresponds to a third direction S. This is bi secant to the directions H and T, that is to say that it forms with each of these directions H and T the same angle. The light zones 20 and 22 are thus symmetrical with respect to the direction S. The light zone 18 has a first side 18.1 parallel to the direction H and a second side 18.2 parallel to the direction T. These two sides form an angle a inside zone 18 which is greater than 90 °, it is advantageously greater than or equal to 95 ° and / or less than or equal to 105 °. The sides

18.1 and 18.2, 20.1 and 20.2, and 22.1 and 22.2 of each of the light areas 18, 20 and 22 are parallel to the adjacent sides 20.2 and 22.1, 22.2 and 18.2, and 18.1 and 20.1, respectively, of the other areas. The angle β between the direction T and the side 16.1 crossed by said direction is advantageously greater than or equal to 100 ° and / or less than or equal to 110 °. Similarly, the angle y between the direction H and the side 16.2 crossed by said direction is advantageously greater than or equal to 100 ° and / or less than or equal to 110 °. The angle δ between direction S and the side 16.3 crossed by said direction is advantageously greater than or equal to 80 ° and / or less than or equal to 100 °. In the present case, it is equal to 90 °.

What has just been described in relation to FIGS. 2 to 4 is valid for the left side of the screen and, by symmetry, for the right side. More specifically, in relation to FIG. 1, the light zones situated to the right of the median axis of symmetry 15 are symmetrical to those on the left side, with respect to the axis 15. To achieve a gradual transition between the left sides and straight, one can provide a transition zone on each side, adjacent to the axis 15, where the hexagon of the basic pattern 16 is gradually deformed, gradually towards the horizontal axis H towards the axis 15, so as to gradually bring the sides 16.2 and 16.4 closer to a direction perpendicular to the horizontal axis H. It is then advantageous for each transition zone to include one or more basic patterns adjacent to the median axis 15, the sides 16.2 and 16.4 are perpendicular to the horizontal axis H.

In FIGS. 5 to 13 are presented different configurations of the basic pattern 16 and of its cutting according to the zones 18, 20 and 22, which have just been detailed.

FIG. 5 illustrates a first mode of arrangement of the basic pattern and the light areas.

The right part of FIG. 5 illustrates a super pattern 24 produced from the base pattern 16 and from light zones identical to those forming said pattern 16. The base pattern 16 is identical to that of FIGS. 2 and 4, said pattern having however, rotated 180 °. The basic pattern 16 of hexagonal shape is surrounded by light zones 18, 20 and 22 identical to those forming the basic pattern 16. These zones are six in number, namely one per side of the hexagonal shape of the basic pattern 16, more precisely still two of each of the zones 18, 20 and 22. More specifically, it can be observed that opposite each of the three complete edges of the hexagon, formed by the zones 18, 20 and 22, is arranged a identical area rotated 180 °. Opposite each of the other three edges of the hexagon, that is to say the edges each formed by two aligned edges of two of the three zones 18, 20 and 22 forming the basic pattern 16, is arranged a zone identical to that three areas 18, 20 and 22 forming the basic pattern 16 located opposite. Super pattern 24 thus has a different hexagonal shape from that of the basic pattern

16.

The left part of FIG. 5 illustrates the super pattern 24 of the left part of the figure arranged in a repetitive and adjacent fashion step by step, thus covering the entire available surface. The generally irregular appearance is apparent.

Figures 6 to 10 illustrate some examples of pictograms that can be produced with the arrangement of Figure 5, according to a first mode.

Figure 6 illustrates a pictogram forming a horizontal line, corresponding to the direction H in Figure 4. It is interesting to note that it is produced by a succession of basic patterns 16 (Figure 5) in the horizontal direction, each third pattern, however, rotated 180 °. However, this rotation has no drawbacks for displaying a horizontal line, given that the three light zones of each of the basic patterns are lit.

FIG. 7 illustrates a pictogram forming a line inclined relative to the vertical. This direction corresponds to the direction T in FIG. 4. Similar to the horizontal line in FIG. 6, the inclined line is formed by a succession of basic patterns aligned in this direction. With reference to FIG. 5, it is interesting to note that this succession of basic patterns is formed by the basic pattern 16 of a super pattern 24 followed by two basic patterns in this inclined transverse direction, each formed by the trios of adjacent peripheral patterns of the two super patterns 24 disposed adjacent in this direction. Similar to the pictogram in FIG. 6, each third pattern is rotated by 180 °, this rotation presenting no drawback taking into account the fact that the three light zones of each of the basic patterns are lit.

Figure 8 illustrates a pictogram forming a solid circle. It corresponds to the lighting of a complete super pattern and the light zones surrounding said super pattern.

FIG. 9 illustrates a pictogram forming a pictogram of the ring type. Similar to the horizontal line in Figure 6 and the inclined line in Figure 7, the ring is formed by a succession of basic patterns approximately describing a circle. More specifically, the circle is formed by six segments of three basic patterns. Each of the segments is aligned in a direction H, T and S in FIG. 4.

Figure 10 illustrates a pictogram forming a triangle. Each of the vertices is formed by a basic pattern while the sides are formed by individual light areas. It is interesting to note that the two inclined sides of the triangle oriented in the directions T and S in Figure 4.

In general, it is understood that the pictograms which have just been detailed are purely illustrative and not limiting. They can in particular be used as a basis for other more complex and / or different size pictograms. They can also be animated so as to indicate for example a direction or a movement.

In general, it is also interesting to note that the three directions H, T and S illustrated in FIG. 4 correspond to three directions of propagation or repetition of the basic patterns. These three directions provide great freedom in the form of the pictograms that can be produced.

Although this is not illustrated, it is interesting to note that illuminating the light areas with different intensity levels, for example ranging from 0 to a maximum value, makes it possible to produce advanced or complex pictograms by means of bright areas with limited resolution. This is particularly true when looking at the screen of the light module at a minimum distance from said screen.

FIG. 11 a second mode of arrangement of the basic pattern and of the light zones.

The right part of Figure 11 illustrates a super pattern 124 made from four basic patterns 116.1, 116.2, 116.3, 116.4. More particularly, a first basic pattern 116.1 and a second basic pattern 116.2 are arranged adjacent in the direction H, the second 116.2 being however rotated 180 ° relative to the first

116.1. A third basic pattern 116.3 is placed adjacent to the second basic pattern 116.2, in the direction S. Similar to the second basic pattern 116.2, a fourth basic pattern 116.4 is arranged adjacent to the third pattern 116.3 in the direction H and rotated 180 °.

The left-hand part of FIG. 11 illustrates the super pattern 124 of the left-hand part of the figure arranged in a repetitive and adjacent fashion step by step, thus covering the entire available surface. The generally irregular appearance is apparent, similar to the first arrangement in Figure 5.

FIG. 12 a third mode of arrangement of the basic pattern and the light zones.

The right part of FIG. 12 illustrates a super pattern 224 produced from two base patterns 216.1, 216.2 and light areas 218, 220 and 222 identical to those forming said base patterns 216.1, 216.2. A first basic pattern 216.1 and a second basic pattern 216.2 are adjacent in the direction S, the second pattern 216.2 being rotated 180 ° relative to the first 216.1. Bright zones 218, 220 and 222 identical to those forming the basic patterns surround the two basic patterns 216.1 and 216.2, similarly to the first arrangement mode in FIG. 5, with the particularity that a luminous zone 218 is arranged projecting on each of the two sides in the direction S.

The left-hand part of FIG. 12 illustrates the super pattern 224 of the left-hand part of the figure arranged in a repetitive and adjacent fashion step by step, thus covering the entire available surface. The generally irregular appearance is apparent, similar to the first and second arrangement in Figures 5 and 11.

FIG. 13 a fourth mode of arrangement of the basic pattern and of the light zones.

The right part of Figure 13 illustrates a super pattern 324 made from four basic patterns 316.1, 316.2, 316.3, 316.4. More particularly, a first basic pattern 316.1 and a second basic pattern 316.2 are arranged adjacent in the direction H, the second 316.2 being however rotated by 180 ° relative to the first

316.1. A third basic pattern 316.3 is placed adjacent to the second basic pattern 316.2, in the direction T. Similar to the second basic pattern 316.2, a fourth basic pattern 316.4 is placed adjacent to the third pattern 316.3 in the direction H and rotated 180 °.

The left part of FIG. 13 illustrates the super pattern 324 of the left part of the figure arranged in a repetitive and adjacent fashion, gradually, thus covering the entire available surface. The generally irregular appearance is apparent, similar to the first, second and third arrangement in Figures 5, 11 and 12.

In general, it is interesting to note that the cutting of the light zones from a basic pattern, in at least two directions, in this case a horizontal direction and a non-perpendicular transverse direction, makes it possible to produce pictograms interesting shapes while presenting an irregular general appearance. The irregular overall appearance gives the light module, and therefore the vehicle, a certain aesthetic and increased perceived quality. It also avoids possible false interpretations by 10 observers in the presence of external light rays reflecting on the screen.
