The input faces of the light guides are arranged on a plane parallel to the plane face of the radiator. The branches of the two light guides are thus in parallel with each other. A disadvantage of this state of the art is that according to the arrangement of the light guides in the projector, their input face can not always be arranged on a plane parallel to the plane face of the radiator.

    [0016] DESCRIPTION OF EMBODIMENTS OF THE INVENTION The identical elements, structure or function, appearing in different figures retain, unless otherwise specified, the same references.
    [0017] The light module 1 for a motor vehicle V according to the invention is described with reference to FIGS. 1 to 10. By motor vehicle, it is meant any type of motorized vehicle. A lighting device 2 of the motor vehicle V comprises the light module 1. In a nonlimiting example taken in the remainder of the description, the lighting device 2 is a projector. The light module 1 comprises: a radiator comprising at least two mounting faces 100 and 101 forming an angle 0 between them; At least two light guides 11 and 12, each comprising an input face 110, 120 and a branch 111, 121; - At least two light sources 14, each disposed at one of said input faces 110, 120 of the light guides 10 associated therewith.
    [0018] In a non-limiting embodiment, the light module 1 further comprises at least one printed circuit board 13, also called PCB ("Printed Circuit Board" in English) to which the light sources 14 are connected.
    [0019] The various elements of the light module 1 are described in detail below. As illustrated in FIGS. 1 and 5 in particular, the light guides 11 and 12 are distinct and the branches 111 and 121 respectively of the light guides 11 and 12 are distinct. They extend in different directions and are distributed over a portion of the projector 2. Each input face 110, 120 of the light guides 11, 12 is adapted to couple the light rays emitted by the light source 14 in the guide associated light 11, 12. It should be noted that the light guides 11 and 12 further comprise decoupling elements (not shown) which make it possible to bring out said light rays on exit faces (not shown) of said light guides 11 12. In a non-limiting example, the decoupling elements 20 are prisms. In a non-limiting embodiment, the light sources 14 are semiconductor emitter chips. In a non-limiting embodiment, a semiconductor emitter chip is part of a light emitting diode.
    [0020] By light-emitting diode is meant any type of light-emitting diode, whether in non-limiting examples of LED ("Light Emitting Diode"), OLED ("organic LED"), AMOLED (Active-Matrix-Organic LED) , or FOLED (Flexible OLED). In a first non-limiting embodiment, the associated light source (s) 14 and associated light guide 11, 12 is adapted to emit white light for carrying out a first photometric function. . In a non-limiting example, the first photometric function f1 is a DRL function for producing a diurnal light. In a second non-limiting embodiment, the associated light source (s) 14 and associated light guide 11, 12 is adapted to emit amber light for the production of a second photometric function f2. In a nonlimiting example, the second photometric function f2 is an ID function for producing a direction indicator. In the case where several light sources 14 are arranged facing each input face 111, 121 of a light guide 11, 12, the first and second photometric functions can be performed in the same projector 2. Thus, in a third non-limiting embodiment, the light source (s) and associated light guide assembly is adapted to emit white light for the production of a first photometric function and amber light for the performing a second photometric function. The light guides 11 and 12 each further comprise a base 113 20 and 123 which each support a complementary referencing means 112 and 122. The bases 113, 123 are respectively disposed on a plane parallel to the input faces 110, 120 of the light guides 11 and 12. As illustrated in FIGS. 1 and 5 in particular, the radiator 10 comprises cooling fins 102. The two mounting faces 100 and 101 of the radiator 10 are substantially flat and extend from one and the same. Furthermore, they are arranged on a side opposite to the cooling fins 102 of the radiator 10. The two mounting faces 100 and 101 make it possible to mount the two light guides 11 and 12 respectively on the radiator 10. either directly (first embodiment described later) or via a support element 3034169 11 (second embodiment described below). For this purpose, in a nonlimiting embodiment, each mounting face 100, 101 of the radiator 10 comprises a first referencing means 104, 105 and each light guide 11, 12 further comprises complementary reference means 112, 122 cooperating with the first referencing means 104, 105. In a non-limiting example, the first referencing means 104 and 105 are referencing orifices, and the complementary referencing means 112 and 122 are referencing pins.
    [0021] More particularly, the referencing pin 112 is inserted into the referencing hole 104 of the mounting face 100 while the indexing pin 122 is inserted into the referencing hole 105 of the mounting face 101. position each light guide 11 and 12 correctly with respect to the radiator 10, and in particular each input face 110 and 120 correctly with respect to the associated light sources 14, and also to prevent the light guides 11 and 12 from moving . Thus, the input face 110 of the light guide 11 is arranged facing the mounting face 100 of the radiator 10, and the input face 110 of the light guide 11 is arranged facing the mounting face 100 of the radiator 10. The angle θ between the two mounting faces 100 and 101 of the radiator 10 is adapted according to the arrangement of the branches 111 and 121 of the light guides 11 and 12 in the projector 2 of the motor vehicle.
    [0022] Thus, in a nonlimiting embodiment, said angle θ is strictly greater than 0 °, in particular strictly less than 180 °. This angle 0 makes it possible to arrange the inlet faces 110 and 120 respectively facing the mounting faces 100 and 101 and along an axis Ax (illustrated in FIG. 1 and in FIG. 5) which is substantially perpendicular to said mounting faces. 100 and 101. The input faces 110 and 120 are thus arranged parallel to the mounting faces 100 and 3034169 12 101 respectively. Thus, the coupling of the light rays emitted by the light sources 14 into the light guides 11 and 12 is maximized. . As will be seen hereinafter, the angle θ thus makes it possible to have for the radiator 5 10 different planes in front of or on which the light sources 14 are arranged. First Embodiment 10 FIG. exploded view of the light module 1 according to a first non-limiting embodiment. According to this mode, each light guide 11, 12 is mounted directly on one of the mounting faces 100, 101 of the radiator 10 associated therewith. Thus, the guide 11 is mounted on the mounting face 100 and the guide 12 is mounted on the mounting face 101. The bases 113 and 123 of the light guides 11 and 12 are in direct contact respectively with the mounting faces 100 and 101 of the radiator 10. FIG. 2 illustrates the light module 1 with the light guides 11 and 12 which are assembled directly on the respective mounting faces 100 and 101 of the radiator 10. As can be seen, the branches 111 and 121 of the light guides 22 and 12 have different directions. According to this mode, at least one printed circuit board 13 (not shown in FIG. 1) is mounted directly on a mounting face of the radiator 10.
    [0023] Figure 3 schematically shows a portion of the light guide 11 according to a first non-limiting embodiment. Note that the same scheme applies for the light guide 12. In the figure, we can see the input face 110 and a portion of the branch 111 of the light guide 11. According to this mode, the light sources 14 are mounted on a printed circuit board 13, the whole being arranged facing the input face 110 of the associated light guide 11.
    [0024] In the nonlimiting example illustrated, there are ten light sources 14 which are mounted on a common support which is thus the printed circuit board 13. In this case, in a non-limiting embodiment, a part of the sources 14 is adapted to emit white light for the realization of the first photometric function f1 and another part of the light sources 14 is adapted to emit amber light for the realization of the second photometric function f2. According to this mode, a printed circuit board 13 (not shown in FIG. 1) is mounted directly on each mounting face 100, 101 of the radiator 10. The assembly is carried out by gluing in a nonlimiting example. Thus, the light module 1 comprises a printed circuit board 13 for each group of light sources 14 of a light guide 11, 12, or two printed circuit boards 13, a group of light sources 14 comprising one or more light sources 14.
    [0025] Figure 4 schematically shows a portion of the light guide 11 according to a second non-limiting embodiment. It should be noted that the same scheme applies for the light guide 12. In the figure, it is possible to see the input face 110, a part of the branch 111 of the light guide 11 and a remote printed circuit board 13 relative to the light guide 11 so as to extend at a distance from the place with respect to which the light guides 11 and 12 are arranged. According to this mode, at least one light source 14 is mounted on each face mounting 100, 101 of said radiator 10.
    [0026] Thus, the light sources 14 are arranged on a common support which is thus the radiator 10. In the nonlimiting example illustrated, there are ten light sources 14 per mounting face 100, 101. In this case also, in a non-limiting embodiment, a portion 30 of the light sources 14 is adapted to emit white light for the realization of the first photometric function f1 and another part of the light sources 14 is adapted to emit amber light for the performing the second photometric function f2. The light sources 14 are thus mounted directly on a mounting face 100, 101 of said radiator 10 and are connected to said at least one printed circuit board 13 by means of bridging via a wire 140 (also called "wire bonding"). " in English). In a first non-limiting embodiment of this second embodiment, the light module 1 comprises a printed circuit board 13 for each group of light sources 14 of each light guide 11, 12, ie two printed circuit boards 13 In this variant, in a first nonlimiting example, each printed circuit board 13 is mounted on an associated mounting surface 100, 101. In a second nonlimiting example, the two printed circuit boards 13 are mounted on a third mounting face (not shown) of the radiator 10 so as to extend away from the place opposite which is disposed In a third nonlimiting example, the two printed circuit boards 13 are respectively mounted on a third and a fourth mounting face (not shown) of the radiator 10 so as to extend to distance from the place with respect to which is disposed the associated light guide 11, 12. In a non-limiting example, the mounting of a printed circuit board 13 is performed by gluing.
    [0027] In a second variant of non-limiting embodiment of this second embodiment, the light module 1 comprises a single printed circuit board 13 for all of the two groups of light sources 14 of the light guides 11, 12. In this variant , in a first non-limiting example, the printed circuit board 13 is mounted on one of the mounting faces 100, 101 of the radiator 10. In a second nonlimiting example, the printed circuit board 13 is mounted on a third face of 3034169 Mounting (not shown) of the radiator 10 so as to extend away from the location opposite which the light guides 11, 12 are arranged. Second Embodiment 5 Fig. 5 shows an exploded view of the light module 1 according to a second non-limiting embodiment. According to this mode, the light module 1 further comprises a support member 15 comprising two support faces 150, 151 which are respectively superimposed on the two mounting faces 100, 101 of said radiator 10 and each light guide 11, 12 is mounted directly on one of said support faces 150, 151 of the support member 15 associated therewith. Thus, the light guide 11 is mounted on the support face 150 and the light guide 12 is mounted on the support face 151. The bases 113 and 123 of the light guides 11 and 12 are in direct contact respectively with the support faces. 150 and 151 of the support member 15. Thus, the support faces 150 and 151 make an angle between them equal to 0 and the light guides 11 and 12 are mounted on the radiator 10 by means of the support member 15 .
    [0028] FIG. 5 also illustrates a connector 154 connected to a control and power supply unit (not shown) of the light sources 14. In a nonlimiting embodiment, each support face 150, 151 of the support element 15 comprises a second referencing means 152, 153 and the complementary referencing means 112, 122 (previously described) of each light guide 11, 12 cooperates with the associated second referencing means 152, 153. In a non-limiting example, the second referencing means 152 and 153 are referencing orifices. More particularly, the referencing pin 112 is inserted into the referencing orifice 152 of the support face 150 while the referencing pin 122 is inserted into the referencing orifice 153 of the support face 151. These second means referenced 152, 153 are respectively positioned opposite the first referencing means 104, 105 of the radiator 10 described above.
    [0029] In a non-limiting embodiment, each support face 150, 151 of the support member 15 comprises mounting means 156 for assembling said support member 15 on the radiator 10, said mounting means 156 cooperating with complementary mounting 107 of said radiator 10. In the nonlimiting example illustrated, the support face 150 10 comprises two mounting means 156a and 156b which cooperate respectively with two complementary mounting means 107a and 107b of the radiator 10 and the support face 151 comprises two mounting means 156c and 156d which cooperate respectively with two complementary mounting means 107c and 107d of the radiator 10. In a nonlimiting example, the mounting means 156 are screws and the complementary mounting means 107 are orifices. According to this second embodiment illustrated in FIG. 5, at least one printed circuit board 13 forms the support element 15.
    [0030] Thus, as can be seen, the printed circuit board 13 comprises two parts which are the two support faces 150 and 151 and which are interconnected via a connecting element 155. The latter is configured so as to be able to adjust 0 angle between the two support faces 150 and 151. In this way, the two support faces 150 and 151 may be well parallel 25 respectively with respect to the two mounting faces 100 and 101 of the radiator 10. In this mode, the light sources 14 are mounted on the printed circuit board 13. In particular, each support face 150, 151 of the printed circuit board 13 comprises at least one light source 14. In the nonlimiting example illustrated, each support face 150, 151 comprises six light sources 14.
    [0031] Thus, the light sources 14 are arranged on a common support which is the printed circuit board 13. FIG. 6 illustrates the light module 1 with the light guides 11 and 12 which are assembled directly on the respective support faces. 150 and 151 of the support member 15. It can also be seen that the light module 1 is mounted in a housing 20 of the projector 2, which housing is described below. As can be seen, the branches 111 and 121 of the light guides 11 and 12 have distinct directions in the housing 20 of the projector 2.
    [0032] FIG. 7 illustrates a sectional view of a portion of the light module 1 integrated in the housing 20 of the projector 2. On this section, there is the light guide 11 with its input face 110, its branch 11 and its referencing pin 112 inserted in the support face 150 of the support member 15 and in the mounting face 100 of the radiator 10. The input face 110 of the guide 11 is arranged parallel to the support face 150 so as to couple at best the light rays emitted by the light sources 14. In the figure, one can also see the connector 154. The two support faces 150 and 151 are in plane contact with respectively the two mounting faces 100 and 101 of the radiator 10 of which the fins 102, which are located on the opposite side to the two mounting faces 100 and 101, can also be seen. As illustrated in FIG. 8, in a non-limiting embodiment, the light module 1 further comprises a flange of FIG. 16 posit fixation ionized on a portion of the light guides 11 and 12. In a non-limiting embodiment, the fastening flange 16 comprises a shape that is adapted to cover: - the bases 113 and 123 of the light guides 11 and 12; A part of the branches 111 and 121 of said guides; a part of the support faces 150 and 151 of the support element 15.
    [0033] Thanks to this fastening flange 16, the light guides 11 and 12 and the support element 15 are well fixed on the radiator 10. In a nonlimiting embodiment, the fastening flange 16 comprises a first orifice of FIG. fastening 160 disposed facing a second fixing orifice 106 of said radiator 10. A mounting screw (not shown) inserted in the first fixing hole 160 and in the second fixing hole 106 makes it possible to fix the fastening flange 16 on the radiator 10 and thus to fix the light guide assembly 11, 12 and support element 15 on the radiator 10.
    [0034] With the attachment flange 16 and the reference pins 112, 122 inserted in the referencing orifices seen above, the light guide assembly 11, 12 and support member 15 can not move. There is thus no mechanical game. The input faces 110 and 120 of the light guides 11 and 12 can not move. The coupling of the rays emitted by the light sources 14 therefore does not change during the use of the projector 2. It will be noted that the fixing flange 16 can of course be used in the first embodiment of the light module 1 previously described. (Light module without the support element 15).

Thus, the lighting device 2 comprises a light module 1 according to the first embodiment described above (without the support element 15) or according to the second embodiment described above (with the support element 15). In a non-limiting embodiment, the radiator 10 is mounted on the housing 20 by means of screws (not shown) which are inserted into mounting holes 103 of the radiator 10 and corresponding mounting holes (not shown) on the housing. 20. In the non-limiting example of FIGS. 8 and 9, the light module 1 is in accordance with the second embodiment described above, namely the light module 1 which comprises the support element 15.

Of course, the description of the invention is not limited to the embodiments described above. Thus, in a non-limiting embodiment, the radiator 10 may comprise more than two mounting faces. Thus, in a non-limiting embodiment, the light module 1 may comprise more than two light guides. In this case, the radiator 10 comprises two mounting faces or more than two mounting faces depending on the arrangement of the light guides in the projector 2 and the position of the input faces of each light guide. It is the same for the support element 15 which will have as many support faces as the radiator comprises mounting faces.
    [0037] Thus, in a non-limiting embodiment, one can have a mounting face on which are mounted one or more light guides. Thus, the invention described has the following advantages in particular: it makes it possible to mount (directly or via the support element 15) different light guides on the same radiator. The cost is thus lower because it uses fewer parts than a solution in which each light guide is mounted on a different radiator; the assembly of the light guides on the radiator (whether directly or via the support member 15) is simple and easy; - It is no longer necessary to have light guides with branches parallel to each other. Any direction and arrangement of the light guides in the housing can be achieved while maintaining optimal photometric performance. This provides more flexibility for the arrangement of the light guides; 3034169 21 - it allows the light sources to be in the axis Ax of the light guides so as to have a better performance in optical terms. There is no more loss of light at the input faces of the light guides; and 5 - it avoids too much distortion of the light guides so that their input face can be positioned correctly on the radiator 10, unlike the solution in which the radiator 10 comprises only one plane face.
