    [0001] The present invention relates to the field of lighting and / or signaling of a motor vehicle and more particularly to the design of light modules capable of emitting daytime running lights. In recent years, car manufacturers have been asked to equip the front of their vehicles with daytime running lights (a device also known by the acronym DRL for "Daytime Running Light"). These daytime running lights are constantly lit as soon as the main beam or dipped beam are not switched on. These daytime running lights are regulated with regard to the color they must emit, namely a white color. Like any type of lighting and / or signaling of a motor vehicle, the daytime running light function must comply with regulatory standards, in this case in particular with standards relating, on the one hand, to photometry and, on the other hand, to minimal lighting area. In other words, it is necessary on the one hand that the intensity and the direction of the light rays emitted by the daytime running lights are correctly calibrated and it is also necessary that the surface used to carry out this daytime running light function is superior. at a minimum regulatory threshold. It will be understood that this question of minimum surface area of illumination can be problematic whereas the designs of motor vehicle headlamps comprising such light modules are particularly well-treated. The present invention is in this context, and it proposes a light module comprising a means for supporting at least one light ray collector in the vicinity of which is disposed a light guide capable of guiding the rays emitted by a light source from an input face to at least two separate output faces. There is thus provided a main exit face, through which the spokes pass in a first direction, and at least one additional exit face which is oriented so that the light rays 30 exiting the guide through this additional face are directed towards the collector, in a second direction distinct from the first direction.
    [0002] According to various features of the invention, the additional output face is perpendicular to said main output face; - The light guide is made of a material capable of being traversed by light, such as a transparent material, in particular polymethyl methacrylate or polycarbonate; the main exit face and / or the additional exit faces comprise toruses in the form of bearings, prismatic elements, ridges, or graining; - The main output face is provided with cores in the form of pads, while the additional output faces are provided with prismatic elements; - The light guide and the light source are respectively fixed on the support means so that the light source is disposed opposite the input face of said light guide; - The light guide is fixed on the support means by means of a mounting plate; the fixing plate comprises an anchoring zone carrying means for fixing the plate on the support means, as well as a zone for fixing the light guide; - An intermediate carrier element is disposed between the plate and the light guide. It will be possible to envisage a first application in which the light module comprises a single collector able to deflect the light emitted by a primary light source. In this case, there is provided an additional optical system disposed on one side of the collector and which comprises the light guide, the light guide having two output faces, one of these output faces being oriented towards this single collector.
    [0003] It may also be envisaged in another application that the support means carries two collectors able to deviate substantially parallel to the optical axis the light emitted by a primary light source respectively associated with each of the collectors. In this case, there is provided an additional optical system disposed between the collectors and which comprises a secondary light source capable of emitting rays in the light guide, the light guide having three exit faces, among which a main exit face substantially perpendicular to the optical axis and two additional output faces opposite and respectively facing each of the collectors. In the latter case of application to two collectors, according to different embodiments: - the light guide extends substantially over the entire height of the collector and takes a tubular form, the light source being disposed under the collector opposite the face input of the light guide formed at an axial end of said guide and the additional optical system further comprises a fixing plate through which the light guide is fixed on the support means. The fixing plate may then comprise an anchoring zone carrying means for fixing the plate on the support means, as well as a fixing zone of the light guide, and the fixing zone may be arranged to allow the insertion of the light guide laterally in the plate, having latching means cooperating with complementary latching means carried by the light guide for maintaining in position of the latter in the fixing plate. the light guide extends substantially half-way up the collector and comprises a head carrying the outlet faces and a tubular body extending said head substantially along the optical axis, the light source being disposed opposite the face of the inlet disposed at the end of the body opposite said head and the additional optical system further comprises a fixing plate and an intermediate fairing through which the light guide is fixed on the support means, the intermediate fairing being adapted to carry the light guide and to be fixed on said plate, itself fixed on the support means. The invention also relates to a motor vehicle in which a light module as described above is set up for lighting and / or signaling of the motor vehicle.
    [0004] Other features and advantages of the invention will appear on reading the detailed description of an embodiment which follows and for the understanding of which reference will be made to the appended figures in which: FIG. 1 is a representation in perspective, three quarters before, a light module according to a first embodiment; FIG. 2 is a perspective view similar to that of FIG. 1, in which components of the light module, namely two collectors carried by a support means, a fixing plate, a light guide and a printed circuit board; carrying a light-emitting diode, are shown in exploded form; - Figure 3 is a partial perspective view, three quarter rear, of the light guide illustrated in Figure 2; and - Figures 4 and 5 are views similar to the views of Figures 1 and 2 of a light module according to a second embodiment, particularly in the form of the light guide and the mounting plate. In what follows, will be designated by longitudinal direction L the direction in the direction of movement of the motor vehicle, and transverse direction T a horizontal direction and perpendicular to this longitudinal direction. The vertical direction V will designate the direction perpendicular to the two previous ones, which also define a horizontal plane. The trihedron L, V, T is placed on the figures for easy reading. But it will be understood that the light module can be arranged according to another orientation without departing from the context of the invention. A light module 2 comprises a support means 4 on which are reported at least one primary light source, not shown here, and at least one elliptical collector 6 adapted to reflect the rays emitted by the primary light source associated with it in the direction of an optical element carried by the support. The optical element is disposed at the second focus of the elliptical collector while the primary light source must be disposed substantially at the first focus of the collector, the right of the clearance formed in the support. This arrangement allows the majority of the rays emitted by the primary light source and passing through the second focus of the collector to be reflected by the optical element in the light direction corresponding to its optical axis.
    [0005] These primary light sources emit directly into the collector and provide high beam or crossover lighting functions when they are turned on, automatically or by manual control of the driver. According to the invention, the module further comprises at least one additional optical system 8 disposed in the vicinity of the collector (s), and this optical system provides the function of daytime running lights, which are switched on when the high beam and high beam lighting functions are used. crossing are extinct. The additional optical system comprises a secondary light source 10, able to emit light in a light guide carried by a platen secured to the means of the support of the light module. This additional optical system is particularly adapted to guide the light emitted by the secondary light source to at least two separate exit faces. Embodiments of the invention will now be described in which the module comprises two collectors attached to the support means. Each collector comprises a substantially elliptical reflective surface, which can be made in the form of an angular sector substantially of revolution. It may however be noted that the surface may not be perfectly elliptical and have several specific profiles provided to optimize the light distribution in the lighting beam produced by the module, as shown in the figures. There are then two primary light sources, each being carried by the support means to be associated with one of the collectors as described above, in the vicinity of the first focus of the corresponding collector. The two collectors are here arranged so that their respective second focus are substantially merged at a point where is placed the focus of the optical element.
    [0006] The two collectors are attached to the support means 4 so as to be arranged side by side in the transverse direction, by providing an intermediate zone 12 which extends between the two collectors 6. The intermediate zone comprises in the upper part a surface of support 14 substantially flush with the manifolds and in the lower part a housing 16 dug longitudinally. The support means has on its upper wall a groove 18 which extends longitudinally the bearing surface of the intermediate zone. The intermediate zone has appropriate dimensions for receiving the additional optical system 8, comprising, as previously described, a light guide 20 and a fixing plate 22. The fixing plate has a rear portion, thus defined arbitrarily with respect to the orientation of the trihedron chosen in the figures, an anchoring zone 24 in the module, able in particular to penetrate into the housing formed in the intermediate zone between the collectors, and in part before an attachment zone 26 of the light guide 20, for maintain it in position both with respect to the collectors as compared to the secondary light source, which is brought opposite the mounting plate. The anchoring zone 24 here has an upper portion 28, whose curved rear face is adapted to follow the curved shape of the intermediate zone, and a lower portion 30 substantially straight. The upper part is hollowed out at its center for weight and design issues, this part of the plate being visible when the plate is brought against the intermediate zone between the collectors (as is visible in Figure 1).
    [0007] The anchoring zone carries two snap-fastening elements in the support means. A plug-shaped male member 32 is formed protruding from the lower part 30, turned away from the fixing plate and the associated light guide, and this male fastening element is adapted to be plugged into a socket 34 formed in the housing 16 formed in the lower part of the intermediate zone 12. A female element, having the shape of an eyelet 36, is adapted to engage around a vertical pin 38 fitted to this effect in the central groove 18 of the support means. It is observed that the male fastening element at the bottom is inserted in a longitudinal direction perpendicular to the direction in which rceillet is fitted around the pin. Thus, the mounting plate is locked in the three directions of space and it provides a stable support for the light guide. As can be seen in the figures, the fixing zone of the light guide is arranged longitudinally in front of the anchoring zone. It has a support face 40 formed by the front face of the anchoring zone, extended at its upper vertical end by a longitudinal tab 42 which ensures a stop in the vertical position of the guide and which has at its free end a dropped edge 44 , which ensures a longitudinal retention of the guide. The dropped edge may have on its inner face, facing the inside of the fixing area, a lug, here not visible, which reduces the distance between the support face and the fallen edge.
    [0008] The support face has the correct curvature so that the light guide bears against this support face over its entire height. The support face is extended at its lower vertical end by a substantially U-shaped receiving bowl 46, of which a first flange 48 is formed by the lower end of the support face, the bottom wall 50 extending perpendicularly thereto. first wing protruding from the support face, and the second wing 52 is formed by a return wall which extends substantially perpendicularly to the bottom wall. A light 54 is arranged in the bottom wall to allow passage of light scattering by the light source, the bottom being disposed between the light source and the light guide. The bottom wall has on its outer face, facing away from the receiving bowl, indexing pads 55 adapted to cooperate with complementary indexing holes 56 formed on the light source.
    [0009] The bowl further comprises first cooperating elements with second elements carried by the light guide to maintain the transverse position of this guide in the fixing plate. These first cooperating elements include in particular a transverse guide rail 58 and a stop 59 disposed at the end of this ramp, integral with the first flange of the bowl, and a tenon extending longitudinally inside the bowl. and came from matter with the second wing (and not visible in the figures). The return wall formed by the second flange 52 of the bowl ensures the longitudinal retention of the lower part of the light guide 20. As can be seen in FIGS. 1 and 2, the return wall may be given a shape adapted to recall the curvature of the collector extending next to the light guide. The light guide 20 has a tubular shape of square section, with four sides and two opposite bases which extend substantially horizontally when the guide is in place in the housing, and which will be called lower base and upper base according to their positioning in housing in the orientation chosen arbitrarily. The light guide is made of a transparent material such as polymethyl methacrylate (also defined by the abbreviation P.M.M.A) capable of being let through the light. It comprises an input face 60 arranged facing the light source and a plurality of output faces through which the light rays, guided inside the guide 20 by successive internal reflection are refracted. The entry face 60 is formed by the lower base, opposite which is placed the light source 10. The input face may have a collimator shape to facilitate the routing of light rays within the guide from light. Of the four sides, there is a side which serves as a contact face 62 against the guide support and three sides which each form an exit face 30 of the light rays. A main exit face 64 is opposed to the contact face and two additional output faces 66 and 68 are perpendicular to the main exit face and the contact face. It can thus be seen that the main exit face is oriented to emit rays substantially parallel to the optical axis of the vehicle, and that the additional exit faces are oriented so that the light rays brought out of the guide through them are directed. to the collectors.
    [0010] On the guide is distinguished a high part specific to the emission of light rays and a lower carrying portion of the guide fixing means on the mounting plate. The main exit face 64 is provided with cores in the form of bearings, and moreover known by the English name of "pillow", while the additional outlet faces 66 and 68 are provided with prismatic elements. A distinction is made between the first type of optical coating made of pads and the second type of optical coating made of prismatic elements, in that the first type of coating allows a high refraction of the light rays impacting the corresponding face of the guide, for the distribution and the bursting of the light beam at the output, and in that the second type of coating makes it possible to refract the light in the direction of the collectors to which the face of the corresponding guide is turned as well as to reflect internally the light rays towards the main exit face. It should be noted, however, that the prisms are arranged in a curvature adapted to guide the light mainly towards the main exit face, and that it is a restricted part of the light rays which pass through the additional exit faces to illuminate the collectors. Such prismatic elements can also be provided on the contact face to reflect and diffract the rays running in the guide. The presence of the support face of the fixing plate opposite the contact face of the light guide makes it possible to avoid the scattering of light rays issuing from the guide at the level of the contact face. For this purpose, as shown in FIG. 3, the contact face advantageously has a frame 70 which follows the curvature of the support face of the plate on which the guide rests, and which surrounds a central portion 72 provided with prisms whose curvature seen from the back of the guide is distinct from that of the frame.
    [0011] A notch 74 is formed at the top of the front face, on a strip 76 without "bearings" and essentially intended to maintain the guide in position, said notch being able to cooperate with the lug made on the inner face of the edge dropped when the light guide is inserted into the mounting plate. In the lower part of the guide carrying means for fixing the guide on the plate, there is provided a tongue 77 on the contact surface of the guide, of height equal to the distance between the guide rails provided on the mounting plate. In addition, a mortise 78 is provided on the front face of the guide adapted to cooperate, when the guide is in place in the plate, with the tenon integrally with the second wing and mentioned above. We will describe below how the shape of the guide allows the realization of the function of the invention that combines a direct light in a first direction, and a diffuse illumination in at least a second direction to increase the minimum surface area. lighting. The light rays emitted in these two types of lighting come from the secondary light source, which is advantageously distinct from the primary light sources, so that it alone ensures the function of daytime running lights. The secondary light source is fixed on the support means facing the entrance face of the light guide. Here the secondary light source is reported under the support means, the source then being able to emit upwards. In the example described, the light source is a light-emitting diode 80 carried by a printed circuit board 82 and able to emit light rays according to an electrical control instruction. It will be understood that other types of light sources could be used without departing from the context of the invention. As can be seen in FIG. 2, two indexing holes 56 are made in the printed circuit board, of diameter substantially equal to the diameter of the indexing pads 55 carried by the fixing plate, on the external face of the bottom wall of the bowl. This ensures, by the cooperation of these indexing means carried by the carrier plate of the diode and the carrier plate of the light guide, that the position of the guide relative to the light source is correct for the rays The luminous light enters in a correct way through the entrance side of the light guide. The assembly and operation of the invention will now be described in greater detail in order to understand, in particular, the dual type of illumination achieved by the daytime running lamps according to the invention, namely a direct illumination through the main exit face of the guide. and indirect lighting by the additional output faces via reflection on the collectors, and to understand for example the dual function of each collector, namely on the one hand the precise optical deviation they realize light rays from light sources primary to leave the module parallel to the optical axis and secondly the less controlled optical deviation they realize light rays from secondary light sources, the important thing here that they are reflected without their direction after reflection is primordial.
    [0012] The light guide is first mounted on the mounting plate, and the guide is inserted laterally into the fastening zone, so that the top of the guide fits between the support face and the fallen edge of the attachment area and so that the lower portion of the guide fits into the receiving bowl, between the first wing and the second wing.
    [0013] The guidance is facilitated by the cooperation of the tongue in the rails until the stop. In this position, the lower part formed on the receiving bowl cooperates with the mortise formed in the lower portion of the light guide and in the upper part the notch formed on the front face of the guide which cooperates with the groove. ergot carried by the fallen edge, and thus ensures the maintenance in position of the guide. The light guide is then blocked in the three positions of the space by the fixing plate. For disassembly, it is possible to remove the guide from the plate by sliding on the same side, forcing the disengagement of the tenon and the mortise.
    [0014] The guide is fixed in position indémontable when the mounting plate is attached to the support means of the collector.
    [0015] For this purpose, the anchoring zone is slid against the intermediate zone disposed between the two collectors, vertically bringing the fixing plate so that the lower part of the anchoring zone enters the housing, then pushing it longitudinally against the intermediate zone so as to plug the male fastening element of the anchoring zone in the socket arranged in the housing. The elasticity of the ring formed at the upper end of the anchoring zone is then used to pass it around the pin disposed on the support means. In this position, it is observed that the light guide is permanently blocked transversely by the collectors. The printed circuit board is then mounted on which the secondary light source has been arranged. The position of this plate is indexed by the cooperation of the holes it carries with the indexing pins carried by the mounting plate and protruding projecting under the collecting means, and the plate is screwed onto the support means by screwing. in this indexed position. In this way, the secondary light source is placed correctly with respect to the entrance face of the light guide. The light emitted penetrates the guide and is directed mainly vertically towards the upper base of the guide against which all the rays are returned in the guide by total internal reflection. In one direction or the other, the rays directed towards the front face out by refraction, facilitated by the optical forms in bearings, to realize the function of daytime running lights in the optical axis. The spokes directed towards the rear face are advantageously reflected towards the main exit face, so that the photometric quality of the daytime running lights is increased, and some of these rays can be directed towards the lateral faces, which form the additional exit faces so that light can be refracted to the collectors opposite which they respectively extend. The lighting surface is thus increased since the light does not come out except through the main exit face, the impression being that it is the whole of the surface covered by the collectors which participate in the function of daytime running lights. The foregoing description clearly explains how the invention makes it possible to achieve the objectives that it has set itself and in particular to propose a light module that allows the exit zones of the light rays at the outlet of the guide to burst, in order to distinctly treat the two problems of photometry and minimal lighting area. The light guide is shaped so that a small amount of light escapes from the sides and illuminates the adjacent collectors, which then have a second function, in addition to their primary function of deflecting the light emitted by primary light sources. for a high beam and crossover function. According to the invention, the photometry is treated on the one hand, provided by the light rays coming out of the main exit face, on which the light is focused at the origin and by which the light rays emerge mainly parallel to the light. optical axis, and the extent of the lighting surface on the other hand, obtained by the rays coming from the main exit face and by the reflection of the rays in the collector. In this way, the minimum lighting surface is respected, while it would not be by the illumination of the main exit face alone, chosen smaller for design issues in particular. It would be possible to arrange the diode in the optical axis, longitudinally behind the support face, a part of which would then form the input face. The diode could then be housed in the recessed part of the anchoring zone. In addition, the arrangement of the light module according to the invention is also advantageous when the high beam and crossover are working and the daytime running lights are actually extinguished. The narrowness of the light guides associated with the daytime running lights do not interfere with the illumination by the collectors in their main function. It facilitates compactness without penalizing the performance of different lighting functions. A lighting function is thus advantageously achieved in which the imposed regulatory standards and the design wishes of the 30 players in the automobile market are respected. These advantages are also obtained by a second embodiment of the invention, illustrated in Figures 4 and 5, wherein the light guide differs in that it does not extend over the entire height of the collectors. It will be understood that the following description of this second embodiment will use the same numerical references for like elements, by adding 100 to the reference given for the corresponding element in the first embodiment. The light guide 120 is no longer in one piece with a substantially straight tube which extends vertically, but it comprises two parts among which a substantially parallelepipedal head 84 and a body 86 formed by a tube which extends longitudinally .
    [0016] The tube has a free end 88 forming an inlet face 160 of the light and which opens into the head, which has, in a similar manner to the previous embodiment, three outlet faces. The main exit face 164 is arranged in the axial extension of the tube, and as previously the additional outlet faces 166 and 168 are disposed substantially perpendicular to the main exit face. The exit faces are provided with bearings and prismatic elements in a manner similar to that of the first embodiment. The particular shape of the light guide involves a different arrangement of the secondary light source and the presence of an intermediate fairing 90 between the fixing plate 122 and the light guide 120. The secondary light source, which is not visible in the figures 4 and 5, is carried by the mounting plate, so as to be opposite the input face of the light guide. In this way, the shape of the mounting plate is also modified in that it has a form of open chest forward to receive the light guide and flipped at this opening by the intermediate fairing. The light source is fixed on the bottom wall, opposite the opening of the plate. As previously, the fixing plate comprises an anchoring zone carrying ratchet means adapted to secure the plate to the support means between the collectors, and a fixing zone adapted this time to cooperate with the intermediate fairing and not directly with the light guide.
    [0017] The intermediate fairing 90 comprises a vertical bar 92 adapted to be snapped onto the mounting plate to cover the opening, the bar being cut at mid-height by a receiving portion 94 of a shape corresponding to the shape of the guide head. from light.
    [0018] The operation of the assembly is similar to that described above, the light being able to exit the light guide mainly through the exit face disposed transversely to the optical axis, and more randomly by the additional lateral exit faces for a lighting of the collectors. It is observed that here the secondary light source is arranged in such a way that the light rays that it emits are directly targeted towards the main exit face. Of course, various modifications may be made by those skilled in the art to the embodiments of the light module according to the invention, which have just been described in a non-limiting manner.
    [0019] By way of example, the orientation and the type of means for anchoring the fixing plate in the support means may differ without going beyond the context of the invention. Similarly, embodiments of the invention in which the module has two collectors have been described. It will be understood that the description can be read without particular difficulty by applying it to a module in which there is a single collector, the additional optical system being on the side, or in which there are more than two collectors, at the least one additional optical system being provided between two adjacent collectors. In the case where the module support means carries a single collector and where a single light guide is placed on one side of the collector, it will be understood that the light guide may advantageously comprise only one additional output face, turned towards this collector.
