    Light module for lighting and / or signaling a motor vehicle
    The present invention relates to the field of light modules used for lighting and / or signaling of motor vehicles, and it applies more particularly to light modules comprising optical devices for the formation of different light beams, and in particular a beam. said to cross and a beam said to road.
    Automobile headlamps are usually composed of a housing which is closed by a transparent wall through which one or more light beams pass. This housing accommodates at least one light module, mainly comprising a light source and an optical system configured to conform the light generated by the light source in order to offer specific lighting and / or signaling services for the vehicle. For example, the optical system can be configured to allow the projection at the exit of the projector of a so-called crossing light beam, in particular in order to limit the glare for drivers of vehicles traveling in the opposite direction.
    In order to perform this function of low beam, the light module comprises at least one light source, a primary optical device positioned opposite the light source to guide the light rays, a cover element which can form a cutting of the light rays emitted in order to form a partial light beam capable of not dazzling third parties at the exit of the projector, and a lens for shaping these rays to form the light beam at the exit of the projector. We understand that the cover element is arranged on the path of the rays, away from the light source and that it is necessary to ensure its position in the long term so that the shape given to the rays for the so-called crossing light beam is stable over time.
    Furthermore, additional light modules can be combined in the same headlight to perform a high beam function, capable of illuminating a road scene with a long range, when the risk of dazzling by third parties is not present. These additional light modules again include one or more light sources and a primary optical device associated with a shaping lens for the projection of the rays.
    For the sake of compactness, light modules are provided in which these two functions are carried out, the light sources and the primary optical devices having to be arranged in relation to each other to carry out these different functions according to the lighting of one and / or the other of the light sources. First light sources are switched on when it is appropriate to emit a first beam of the low beam type, and second light sources are switched on in addition to emit a beam complementary to this first beam to form by combination of the two beams a beam of high beam type.
    Such arrangements may involve the installation of primary optical devices, and / or of a cover element, which have a distal end face remote from a base forming a support for light sources. It is understood that the games of manufacture of these primary optical devices, produced in series, can generate a positioning defect. A manufacturing defect at the base of the primary optical device, and in particular at the place where the base will be fixed to the support, can cause the device to be positioned incorrectly, all the more so as the overhang is tall. Furthermore, it appeared that the mechanical vibrations and the temperature variations to which the light module is exposed during its use can cause, over time, a more or less pronounced variation in the inclination of these primary optical devices with respect to the light source. This inclination has the disadvantage of modifying the area illuminated by the low beam, which can be unpleasant or even dangerous for drivers of vehicles traveling in the opposite direction. It then becomes necessary to carry out regular maintenance of the light module in order to correct this defect to prevent any accident.
    The invention proposes to produce a light module comprising a primary optical device whose position is less likely to vary over time with respect to the light source of the light module.
    To this end, the subject of the invention is a light module for lighting and / or signaling a motor vehicle, comprising a base supporting at the level of a first face at least one light source emitting light rays s extending mainly along an optical axis perpendicular or substantially perpendicular to the first face, and a primary optical device comprising a receiving part facing at least a part of the light source and a face of spoke exit opposite to the receiving part. The terms “receiving part” and “exit face” mean respectively the part of the primary optical device illuminated by the light source and the face of the primary optical device by which this light is emitted in the direction of a lens. shaping.
    The light module according to the invention is remarkable in that it comprises at least one arm projecting from the first face of the base and holding the primary optical device at a holding zone located between the part of reception and the output face of the primary optical device. In this way, it is possible to limit or prevent the inclination of the primary optical device relative to the base and to ensure a reliable position of the primary optical device in the light module.
    According to different characteristics of the invention, taken alone or in combination, it can be provided that:
    - The arm is arranged facing a lateral face of the primary optical device.
    - The holding zone is closer to the exit face than to the reception part of the primary optical device. Preferably, the center of the holding zone is located at a distance from the emission face equal to or less than a quarter of the distance separating the reception and emission faces of the primary optical device, preferably at an equal distance or less than an eighth of this distance.
    - The arm and the primary optical device comprise complementary members for cooperating in said holding zone. The organs are complementary in that their shape allows cooperation preventing the movement of the primary optical device relative to the arm.
    - The complementary members include an opening formed on an inner face of the arm facing the primary optical device and a lug formed on a lateral face of the primary optical device. It is understood that according to an alternative embodiment, it could be provided that the arm includes an appendage at its inner face, configured to fit into a notch present on a side face facing the primary optical device.
    - The arm includes a groove made at an inner face facing the primary optical device, so as to facilitate guiding the primary optical device along the arm during their assembly.
    - The opening is arranged in the extension of the groove.
    - The arms have sufficient elasticity to allow their spacing to facilitate the cooperation of the complementary members, and in particular the passage of the lug from the groove to the opening. The groove can be delimited by an inclined plane at the opening, so as to facilitate the passage of the lug out of the groove.
    - The light module comprises at least one chassis made integral with the base, the chassis comprising the arm or arms.
    - The frame forms a frame extending partially around the light source. In this context, the light module may include at least two separate frames positioned so as to maintain the primary optical device at two opposite faces.
    - The frame forms a frame extending all around the light source.
    - The frame of the chassis is in contact with the first face of the base, the arms extending from the frame opposite said first face of the base.
    - The frame is held against the first face of the base by means of reversible fixing means, for example screws. According to an alternative embodiment, the frame is glued against the first face of the base. It can also, without departing from the context of the invention, be assembled by deformation of the material, and for example by crimping and gluing.
    - The arm (s) came integrally with the base, so as to form a one-piece assembly. By one-piece assembly, it is understood that the arms and the base are integral and in one piece, and that their separation can only be carried out by deterioration and breakage of one and / or the other.
    - At least one arm comprises in the vicinity of its free end a slot of shape and dimensions complementary to those of a bar arranged projecting from the side face of the primary optical device.
    - The primary optical device comprises at least one leg extending a guide body of the primary optical device, said leg having a tab provided with a pin configured to cooperate with an orifice formed in the base.
    The light source comprises at least one light-emitting diode pressed directly or via a thermally conductive paste against the base and at least one electrical conductor connecting the light-emitting diode to an electric source. The thermally conductive paste may for example be a glue or a thermal adhesive.

    In the following description, the longitudinal or lateral names, above, below, front, behind refer to the orientation of the light module 2 as it is intended to be integrated in a headlight of a motor vehicle. A longitudinal direction corresponds to an optical axis A along which the light rays generated by the light module 2 extend mainly. The lateral orientation corresponds to a straight line perpendicular to the optical axis A and which extends horizontally. Finally, the vertical direction corresponds to an orientation perpendicular to the optical axis A and to the lateral orientation.
    FIG. 1 illustrates a light module 2 according to the invention, otherwise called an optical module, the function of which is to generate and project one or more light beams on a road. Such a light module 2 is intended to be installed in a headlight of a motor vehicle not shown in the figures in order to facilitate understanding of the invention. It will be noted that the headlight mentioned here generally comprises a rear housing closed at the front by a transparent glass, the latter being traversed by the light rays created by the light module according to the invention. Such a projector can thus receive in its internal volume, delimited by the rear housing and the transparent glass, a plurality of light modules, and at least one light module according to the invention.
    Such a light module 2 forms a unitary sub-assembly, that is to say an object which can fulfill its function without any other contribution than the electrical energy necessary for its ignition, and if necessary with the help of a electric current regulation module to protect the module from excessive temperatures.
    The light module 2 according to the invention is arranged to create a beam of low beam and a beam of high beam. As will be explained in more detail below, the light module 2 is adapted so that the main beam is the combination of the low beam with a complementary beam which illuminates above and / or below the beam of low beam, the assembly thus forming the beam of high beam.
    The light module 2 comprises at least one light source 4 notably visible in FIG. 2. It also includes at least one lens 6 arranged at one end of the module so as to be traversed by the light rays emitted by the light source 4. Such a shaping lens 6 participates in the formation of the desired light beam, whether it is a beam of the low beam type or a beam of the high beam type. In other words, the shaping lens 6 forms a first longitudinal end of the light module 2.
    FIG. 1 also shows the presence of a support 8 for shaping lens 6 which has a substantially tubular shape and which extends between a base 10 and the shaping lens 6. The lens can be snapped directly onto the support, or else be fixed by means of a fixing ring 11 pressing the shaping lens 6 against a longitudinal end of the support 8. This support 8 also provides mechanical referencing of the position of the putting lens in shape 6 with respect to the light source 4, via the base 10, so as to guarantee a determined position of the shaping lens 6 with respect to the light source 4.
    The support 8 is in particular formed by two longitudinally consecutive tubular sectors of different cross section. A first tubular sector 12 bears against a first face 14 of the base 10 facing the lens, while a second tubular sector 16 extends the first tubular sector 12 and forms a zone for receiving the shaping lens 6. The first tubular sector 12 can be flush with a dissipation member 18, intended to remove from the light module 2 at least part of the heat generated by the light source 4. The support 8 can be made integral with the base 10 by the presence of screw pressing the support 8 against the first face 14 of the base 10.
    We will now describe a first embodiment, with particular reference to Figures 2 to 8. Figure 2 shows a part of the light module 2, including the base 10 without support 8, so as to facilitate understanding of the arrangement in the light module 2 of the light source 4, here composed of a set of associated components so as to form three sub-assemblies capable of supplying one after the other or at the same time light beams. The light source 4 therefore comprises several light-emitting diodes 22 of identical or different colors. The light-emitting diodes 22 are in contact with the first face 14 of the base 10, either directly or by means of a thermally conductive tab.
    According to the present example, the light module 2 comprises three rows of light-emitting diodes substantially parallel to one another. Each row thus forms a subset of light sources from which a first subset of light sources 24 can be distinguished, a second subset of light sources 26 and a third subset of light sources 28. It is understood that the illustrated arrangement is given by way of example, and that the light-emitting diodes could for example be arranged to form three functional sub-assemblies without an arrangement in parallel rows being visible on the module.
    The first subset of light sources 24 is responsible for creating the light rays for a first light beam of the low beam type, the second subset of light sources 26 is responsible for creating the light rays for a complementary light beam forming by addition with the first beam a second beam of high beam type, and the third sub-assembly of light sources 28 is responsible for creating the light rays to over-intensify a central area at the edge of the second beam, namely the edge forming a junction with the first beam when the two beams are projected simultaneously.
    In the example illustrated, the first sub-assembly of light sources 24 comprises six light-emitting diodes 22, substantially aligned in a lateral direction. The second subset of light sources 26 and the third subset of light sources 28 respectively comprise four and two light-emitting diodes 22 distributed on two substantially lateral lines, the second subset of light sources 26 being positioned between the first subset of light sources 24 and the third subset of light sources 28.
    Each of the light source sub-assemblies 24, 26 and 28 is disposed against the first face 14 of the base 10, in a central zone on this first face 14 as shown in FIG. 2. This allows to clear around this central zone a peripheral zone to allow the fixing of a frame 30 according to one aspect of the invention.
    We will describe in the following the cooperation between the frame 30, in particular visible in FIGS. 2 and 3, and at least one primary optical device 50 disposed opposite a subset of light sources, in particular visible in the figure. 4.
    More specifically, the chassis 30 illustrated in Figures 2 and 3 comprises a frame 32 defining a closed outline of rectangular shape. The dimensions of the frame are adapted so as to allow it to be positioned around the light source 4 and its retention against the first face 14 of the base 10 by means of screws 20. The light source 4 is thus surrounded by the frame 32. Of course, the shape and the dimensions of the frame can be adapted according to the dimensions and the shape of the light source 4.
    The frame 32 has a first face 34 intended to be pressed against the first face 14 of the base 10 when the frame is fixed on the base.
    The frame 30 also comprises two arms 36 extending from the frame 32 in the direction of the shaping lens 6 in a longitudinal or normal direction relative to the plane defined by this frame 32. This results, when the frame 32 is fixed on the base 10, that the arms 36 extend mainly perpendicular to this base 10. The arms 36 extend from opposite edges of the frame 32, and they are more particularly positioned at each end of the lateral line formed by the second sub-assembly of light sources 26. The arms 36 respectively have an inner face 38 facing the opposite arm, so that the inner faces 38 of the arms are opposite. Each inner face 38 has a groove 40 extending over a part of the arm 36. More specifically, each groove 40 extends to open onto the first face 34 of the frame as illustrated in FIG. 3. The grooves 40 are preferably identical and of dimensions adapted to allow the guiding of a lug 42 secured to the primary optical device which will be described later. Each arm 36 also has an opening 44 at a distal end 46, the opening 44 being arranged in the longitudinal extension of the groove 40. The term “distal” means the end of an arm 36 which is the farthest from the base 10 and the light source 4, and which is therefore the closest to the shaping lens 6. The openings 44 pass right through each arm 36. The openings 44 are dimensioned for each receive a lug 42 as mentioned above after its guidance by a corresponding groove 40. It is understood that, unlike the grooves 40, the openings 44 aim to lock the lug in position along the inner face 38 of the arm 36.
    It should be noted that the openings and the pins are here an embodiment of complementary members carried by the arms of the chassis and by the primary optical device 50 as will be described in more detail below, these complementary members having shapes configured to allow this blocking in position. Once the lugs 42 are inserted into the openings 44 as illustrated in FIGS. 5 to 7, a holding zone 62 is created for the primary optical device 50 to the chassis 30. The primary optical device 50 is then perfectly held by the arms 36 so as to prevent the primary optical device 50 from moving relative to the chassis 30.
    The holding zone 62 is here formed in the vicinity of the distal end 46 of each arm, it being understood that it could be formed more or less far from the outlet face 54 relative to what is illustrated. It is however desirable that this holding zone, in order to ensure the stability of the device, is arranged closer to the outlet face 54 at the end of the guide body 53 of the primary optical device than to the reception part 52 of this primary optical device. 50.
    It should be noted that the chassis 30 has at its first face 34 notches 48, configured to delimit spaces for receiving tabs 74 secured to optical elements, as will be described below.
    As may have been mentioned previously, a light module 2 according to the invention also comprises at least one primary optical device 50 as illustrated in FIG. 4, capable of being arranged directly opposite the light source 4, between the latter and the shaping lens 6. In the example illustrated, it is notable that this primary optical device 50 participates equally well in the formation of a light beam of the high beam type, by guiding the light rays inside the optical device, only with the formation of a light beam of the low beam type, by cutting off the rays treated elsewhere by another primary optical device. For this, the primary optical device 50 comprises a part 52 for receiving the light emitted by the second sub-assembly of light sources 26, a guide body 53 extending longitudinally and having at its free end, that is to say the end opposite to the receiving part 52, an exit face of the spokes 54. The guide body 53 has a shape of block delimited by main faces 56 and lateral faces 58 making it possible to guide the light emanating from the receiving part 52 towards the outlet face 54 and towards the shaping lens 6.
    As will be described below in more detail, at least one main face 56, namely the main face facing the side of the first subset of light sources 24, can be provided with an opaque or reflective coating, intended to cut the rays emitted by the first subset of light sources 24.
    It should be noted that the primary optical device 50 according to the invention also comprises two legs 66 disposed respectively in the extension of a lateral face 58, on either side of the receiving part 52. Each leg 66 comprises at its free end, opposite the guide body 53, a tab 67 forming an elbow and having a contact face with the first face 14 of the base 10. The tab 67 comprises, projecting from this contact face, a pin 68 configured to fit into an orifice made in the first face 14 of the base 10 (not visible in the figures). The insertion of the pins 68 into the base 10 facilitates the positioning on the base 10 of the assembly formed by the pre-assembly of the frame 32 and the primary optical device 50, while ensuring that the receiving part 52 of the device primary optic 50 is correctly positioned relative to the second subset of light sources 26. As an illustrative example, reference may be made to FIG. 8 to illustrate this preassembly position. The combination of the cooperation between the pins 68 integral with the primary optical device and the base on the one hand and the cooperation between the pins 42 also integral with the primary optical device and the arms 36 of the frame 32 on the other allows optimal maintenance of the primary optical device, with respect to the base and each of the subsets of light sources.
    In fact, it suffices for the operator to hold the frame 32 at the base 10 by means of screws 20 as illustrated in FIG. 6, to ensure that the inclination and the position of the primary optical device 50 will not change not, with respect to the light source 4, over time and this whatever the vibrations and the temperature variations undergone by the light module 2.
    In FIG. 7, a set of primary optical devices has been made visible, configured to be respectively opposite a subset of light sources, with additional optical devices arranged on either side of the primary optical device described above. above. Among these additional primary optical devices, a first additional primary optical device 71 can be distinguished, arranged opposite the first subset of light sources 24, and a second additional primary optical device 72 arranged opposite the third subset of light sources 28. The first and second additional primary optical devices 71, 72 take, for example, the form of collimators, each collimator being arranged to collect at least part of the light rays from the light sources and to redirect said light rays to the shaping lens 6. It should be noted that these first and second additional primary optical devices 71, 72 may include retaining tabs 74 configured to fit into the notches 48 formed in the first face 34 of the frame 32, in order to ensure their position by clamping against base 10 by said frame 32.
    A light module equipped with such a set of optical devices allows in particular the formation of a beam of the low beam type by the emission of light rays through the first additional primary optical device 71, and the formation of a beam of high beam type by the simultaneous emission of light rays through each of the module's primary optical devices. The primary optical device, described above in the form of a block, participates on the one hand in guiding the light rays emitted by the second subset of light sources 26 to the exit face 54 and on the other hand in the cut-off. rays which propagate between the first additional primary optical device 71 and the shaping lens 6.
    In this context illustrated in FIG. 7, it is doubly important to freeze the position of the primary optical device 50 relative to the base 10 carrying the light source, to ensure that the complementary beam generated by this primary optical device 50 is correctly positioned with respect to the optical axis A of the light module, and to ensure that the end edge forming the beam cutting edge is also correctly positioned on the ray path to form a so-called crossing beam which either regulatory.
    It is understood that the presence of the arm 36 and holding means arranged between this arm and the primary optical device is necessary in this context, where the primary optical device is elongated so that the outlet face, opposite the base 10, is arranged at a great distance from this base. By large distance, it is understood that the dimension between the base 10 and the exit face of the primary optical device, otherwise called length L of the primary optical device, is greater than the dimension of this primary optical device along any parallel axis. to the plane defining the first face 14 of the base 10, and for example its thickness E visible in FIG. 8.
    The presence of at least one arm and holding means has been described according to a first embodiment in the above, but it is understood that other embodiments can be implemented, and for example the second mode illustrated in FIG. 9.
    This second embodiment differs from the above in that the arms 136 are here integrally formed with the base 10, so as to form a one-piece assembly, instead of being carried by an independent chassis. It is understood that the arm extends projecting from the base at a greater distance from the primary optical device than when this arm is carried by a frame capable of covering the legs extending this primary optical device. In the example illustrated, the arms are arranged on the base at the periphery of these legs, so as not to interfere with their attachment to the base.
    Consequently, in order to make the arms 136 and the primary optical device cooperate in the holding zone 162, the primary optical device 50 comprises at least one bar 76 projecting from the lateral face 58, over a sufficient distance to come into contact. taken in a slot 78 produced in the corresponding arm 136.
    In the example illustrated, each arm 136 comprises, in the vicinity of the free end, such a slot 78, each slot having a shape and dimensions complementary to those of the bar 76 arranged projecting from the lateral face 58 of the primary optical device 50.
    The foregoing description clearly explains how the invention makes it possible to achieve the objectives which it has set itself and in particular to propose a light module allowing easier and safer maintenance over time of a primary optical device in screw vis-à-vis a light source 5 of a light module. Indeed, the use of a frame according to the invention makes it possible to ensure that the position as well as the inclination of the primary optical device with respect to the light source does not vary over time as a function vibrations and / or temperature variations undergone by the light module. This is why the present invention provides a light module that is safer to use. The description made on an element naturally applies to any element of the same nature and the scope of the invention extends to any equivalent element.
