Description

[Technical Field]

[0001] The invention relates to a lighting device for a headlamp, in particular for a front headlamp of a vehicle. The invention also relates to a vehicle equipped with such a lighting device. Summary of the Invention

[0002] Motor vehicles are conventionally equipped with headlamps, particularly front headlamps or headlights, intended to illuminate the road ahead of the vehicle at night or in low light conditions. These headlamps are generally usable in two lighting modes: a first, "high beam" mode, and a second, "low beam" mode. The "high beam" mode allows the road to be brightly illuminated far ahead of the vehicle. The "low beam" mode provides more limited illumination of the road, while still providing good visibility without dazzling other road users. For this purpose, the headlamp may comprise one or more separate light-emitting modules.

[0003] Conventionally, each light-emitting module is mounted on at least one movable support, which is in particular capable of pivoting, to allow adjustment of the inclination of the light-emitting module in order to ensure that the road is properly illuminated by the light-emitting module without adversely affecting other road users. Such a movable support can be a main support or an intermediate support common to multiple light-emitting modules, moved by one or more adjustment means, specific to a given module.

[0004] In particular, when a headlamp includes multiple light-emitting modules, it is known practice to enable independent or simultaneous adjustment of said modules via connecting means. However, such connecting means have the drawback of being bulky, complex, and unsuitable for an increasing number of light-emitting modules, such as in the case of headlamps including more than two light-emitting modules. Furthermore, connecting means are limited by numerous dimensional constraints imposed by the aesthetic appearance of the vehicle, by the space available for their integration, and by the various lighting functions that the headlamp must accommodate.

[0005] The present invention addresses this situation and aims to provide a lighting device with a plurality of light emitting modules that allows for easy and appropriate adjustment of the light emitting modules while minimizing the installation area of ​​the lighting device.

[0006] The invention relates to a lighting device for a vehicle headlamp, in particular a front headlamp, comprising a main mounting plate and a plurality of separate light emitting modules, in particular at least two light emitting modules, each mounted on an intermediate support, each intermediate support being mounted to the main mounting plate so as to be movable about a pivot axis, in particular a horizontal axis, specific to that light emitting module, the pivot axes of the different light emitting modules being parallel and distinct. The lighting device further comprises: - first adjustment means configured to move the main mounting plate about a first adjustment axis, in particular a vertical axis, perpendicular to the pivot axes of the modules, to allow simultaneous movement of a plurality of modules; - second adjustment means configured to simultaneously move at least two of the plurality of modules relative to the main mounting plate by tilting each module about its own pivot axis; - at least one member for connecting an assembly or subassembly of two modules of the plurality of modules, the at least one member connecting intermediate supports supporting the two modules in such a way as to allow simultaneous movement of the two modules by transmitting the movement of one of the two modules to the other of the two modules.

[0007] According to the first embodiment, the two light emitting modules can be at least partially overlapped along a direction perpendicular to the pivot axis, in particular along a vertical direction, and in particular, the two light emitting modules can be offset relative to one another along a direction perpendicular to the first adjustment axis and the pivot axis, in particular along a longitudinal direction.

[0008] The connecting member may comprise a rod connected to one of the two modules at a first connection zone and to the other of the two modules at a second connection zone, the rod being bent to have at least a first elbow extending near the first connection zone and a second elbow extending near the second connection zone.

[0009] In particular, the distance separating the pivot axis of one of the two modules from the first connection zone along the direction defined by the first adjustment axis can be the same as the distance separating the pivot axis of the other of the two modules from the second connection zone.

[0010] The lighting device may further comprise at least one guide means for guiding a connecting member at least partially connected to an intermediate support specific to one of the two modules and / or at least partially connected to an intermediate support specific to the other of the two modules.

[0011] According to the second embodiment, the two light emitting modules can be arranged side by side along a direction parallel to the pivot axis, in particular along a horizontal direction, and in particular, the two light emitting modules can be offset relative to one another along a direction perpendicular to the first adjustment axis and the pivot axis, in particular along a longitudinal direction.

[0012] According to a second embodiment, the connecting member may comprise a slider connected to one of the two modules in a first connection zone and connected to the other of the two modules in a second connection zone, the slider being configured to interact with the main mounting plate so as to be moved along a direction perpendicular to the first adjustment axis and to the pivot axis, in particular along the longitudinal direction.

[0013] In particular, the distance separating the pivot axis of one of the two modules from the first connection zone along the direction defined by the first adjustment axis can be the same as the distance separating the pivot axis of the other of the two modules from the second connection zone.

[0014] According to a third embodiment, the lighting device can include three light-emitting modules. In one example, the two light-emitting modules are formed by a first light-emitting module and a second light-emitting module, and the lighting device further includes a third light-emitting module movably mounted to the main mounting plate via intermediate supports at two pivot points defining a pivot axis specific to the third light-emitting module and parallel to the pivot axes of the first and / or second modules. The device is configured such that the first adjustment means allows simultaneous movement of the three modules about the first adjustment axis via the main mounting plate, and the second adjustment means allows simultaneous movement of at least two of the three modules about their respective pivot axes.

[0015] According to a particular embodiment, the first light emitting module and the second light emitting module are at least partially overlapped along a direction perpendicular to the pivot axis, in particular along a vertical direction, and the second light emitting module and the third light emitting module are juxtaposed along a direction parallel to the pivot axis, in particular along a horizontal direction, and the at least one connecting member connects intermediate supports (217a, 217b) supporting the first and second modules in a manner that allows movement of one of the first and second modules relative to the other and vice versa. The second adjustment means comprises a first member (25a) for connecting the first module (211a) and the second module (211b), and a second member (25b) for connecting the second module (211b) to a third module (211c) which connects the intermediate supports (217b, 217c) that support the second and third modules so as to enable simultaneous movement of one of the second and third modules relative to the other and vice versa, thereby enabling simultaneous movement of the second and third modules about their respective pivot axes.

[0016] The first light emitting module and the second light emitting module may be offset relative to each other along a direction perpendicular to the first adjustment axis and to the pivot axis, in particular along the longitudinal direction.

[0017] The first connection member may comprise a rod connected to one of the first and second modules at a first connection zone and connected to the other of the first and second modules at a second connection zone, the rod being bent so that it has at least a first elbow extending near the first connection zone and a second elbow extending near the second connection zone.

[0018] Along the direction defined by the first adjustment axis, the distance separating one of the pivot axes of the first light-emitting module and the second light-emitting module from the first connection zone can be the same as the distance separating the other of the pivot axes of the first light-emitting module and the second light-emitting module from the second connection zone.

[0019] The lighting device may further comprise at least one guide means for guiding the first connecting member at least partially connected to an intermediate support specific to one of the first and second modules and / or at least partially connected to an intermediate support specific to the other of the first and second modules.

[0020] The second light emitting module and the third light emitting module may be offset relative to each other along a direction perpendicular to the first adjustment axis and to the pivot axis, in particular along the longitudinal direction.

[0021] The second connecting member may comprise a slider connected to one of the second and third modules at a first connecting zone and connected to the other of the second and third modules at a second connecting zone, the slider being configured to interact with the main mounting plate to be moved along a direction perpendicular to the first adjustment axis and to the pivot axis, in particular a longitudinal direction.

[0022] Along the direction defined by the first adjustment axis, the distance that one of the pivot axes of the second module and the third module is spaced from the first connection zone can be the same as the distance that the other of the pivot axes of the second module and the third module is spaced from the second connection zone.

[0023] In particular, regardless of the embodiment implemented, the first adjustment axis may be interposed between at least two of the three light emitting modules along a direction parallel to the pivot axis.

[0024] In particular, regardless of the embodiment implemented, the first adjustment axis may be centrally located within the main mounting plate along a direction parallel to the pivot axis.

[0025] The invention is also applicable to motor vehicles including at least one lighting device as described above. [Brief explanation of the drawings]

[0027] 1 shows diagrammatically an embodiment of a vehicle 1, in particular an automotive vehicle 1, which is provided with one or more headlamps 3. In this example, said headlamps 3 are front headlamps.

[0028] In the following description, by convention, the direction in which the motor vehicle 1 moves linearly is defined as the longitudinal direction X. The forward direction corresponds to the direction in which the motor vehicle 1 normally travels along its longitudinal axis, and is opposite to the reverse direction. The direction perpendicular to the longitudinal direction and lying in a plane parallel to the ground is referred to as the lateral direction Y. The direction perpendicular to the directions X and Y, in other words perpendicular to the ground on which the vehicle 1 stands, is referred to as the vertical direction Z. This defines the direct reference system XYZ shown in the figures that require it.

[0029] Similarly, the terms "vertical," "horizontal," "up," "down," "right," and "left" refer to directions or orientations that are easily identifiable in the operational position of the headlamps provided on the vehicle 1. The term "up" refers to an orientation toward the roof and / or hood of the vehicle 1, and the term "down" refers to an orientation toward the sill of the vehicle 1. The term "right" refers to an orientation toward the right-hand side of the road scene in the direction of travel of the vehicle 1, while the term "left" refers to an orientation toward the left-hand side of the road scene in the direction of travel of the vehicle 1.

[0030] The headlamp 3 comprises a housing 5, which is open on one side and is depicted in particular in Figure 2 by a dashed line, in which at least one lighting device 7 is arranged. The headlamp 3 also comprises an outer lens (not shown) which closes the opening of the housing 5.

[0031] Generally, the lighting device 7 comprises a main mounting plate 9 on which a plurality of separate light emitting modules 11, i.e., at least two light emitting modules 11, are mounted. By way of non-limiting example, each light emitting module 11 may comprise a module 11 that emits a low beam and / or a high beam. For example, a light emitting module may comprise at least one light source, one or more optical components for shaping the light beam emitted by the light source, and optionally a heat sink.

[0032] The main mounting plate 9 is movably mounted relative to the housing 5. The lighting device 7 comprises first adjustment means 13 arranged on the main mounting plate 9, the first adjustment means 13 being configured to move the main mounting plate 9 about a first adjustment axis 1000 to enable simultaneous movement of different modules 11 of the plurality of modules 11 supported by the main mounting plate 9. Such adjustment means can be seen in particular in Figures 7 and 10. For example, the main mounting plate 9 comprises rotation means 15 having a shape complementary to receiving means (not shown) included in the housing 5. Such rotation means 15 and receiving means, for example, together define a pivot connection.

[0033] The first adjusting means 13 is configured to act in particular on a first actuation point P1 comprised in the main mounting plate, to rotate the main mounting plate 9 around a first adjustment axis 1000. Preferably, such first actuation point P1 therefore extends at a non-zero distance from the first adjustment axis 1000. As a result, the mounting plate collectively supports the plurality of light-emitting modules 11 inherent in the lighting device 7, the light-emitting modules 11 being freed from any direct mechanical connection with the housing 5.

[0034] In the example shown, the first adjustment axis 1000 extends parallel or substantially parallel to the vertical direction Z. The main mounting plate 9 can therefore pivot horizontally to the right or left to allow adjustment of the angular position of the main mounting plate 9 and the light emitting module 11 relative to the housing 5 about the first adjustment axis 1000. It will be appreciated that, since the light emitting module 11 is entirely supported by the main mounting plate 9, adjusting the angular position of the main mounting plate allows simultaneous adjustment of the angular position of the light emitting module 11. According to one alternative not shown, the first adjustment axis 1000 can extend parallel to the lateral direction Y.

[0035] Furthermore, the light emitting modules 11 are movably mounted relative to the main mounting plate 9 via a plurality of intermediate supports 17. In particular, the lighting device 7 includes as many intermediate supports 17 as there are light emitting modules 11, such that each given light emitting module 11 is mounted on its own intermediate support 17. In particular, the intermediate supports of each light emitting module are separated from the elements forming the light emitting module. Therefore, the intermediate supports are different from heat sinks. For example, the intermediate supports can be made from a synthetic polymer material, such as plastic, which is preferably not thermally conductive.

[0036] The intermediate supports 17 are each connected to the main mounting plate 9 at two pivot points 19 that define a pivot axis 2000 specific to the intermediate support 17 and thus to the light-emitting module 11 in question, said pivot axis 2000 being distinct from one module 11 to another. The term "pivot point" is used here to mean the connection zone between the main mounting plate 9 and a given intermediate support 17. In particular, the pivot points 19 correspond to pivot elements 21, for example of the ball-joint connection type, that allow the light-emitting module 11 to pivot about its pivot axis 2000. The different pivot axes 2000 of the light-emitting modules 7 are parallel to one another. Preferably, they extend parallel to the horizontal direction and, in particular, in some embodiments are oriented substantially in the transverse direction Y.

[0037] The lighting device 7 further comprises second adjustment means 23 configured to simultaneously move all or some of the modules 11 relative to the main mounting plate 9. The second adjustment means 23 make it possible to tilt each light-emitting module 11 about its own pivot axis 2000, which is here horizontal or substantially horizontal, thereby adjusting the height of the projected beam, for example depending on the attitude of the vehicle 1. According to the above-mentioned alternative, the second adjustment means 23 may make it possible to make adjustment about a vertical axis or a substantially vertical axis. The second adjustment means 23 acts on a second actuation point P2 comprised on one of the intermediate supports 17 and makes it possible to manipulate the pivoting of the intermediate supports 17 relative to the main mounting plate 9 about their respective pivot axis.

[0038] To ensure simultaneous movement of at least some of the plurality of light-emitting modules 11 during adjustment of the height of the light beam, the lighting device 7 comprises at least one member 25 for connecting two of the plurality of modules 11. Such a connecting member 25 connects the intermediate supports 17 supporting the two modules 11 in a manner that enables their simultaneous movement by transmitting the movement of one of the two modules 11 to the other of the two modules 11. In other words, the at least two modules and the connecting member 25 can form an assembly or subassembly within the plurality of modules 11 of the lighting device 7. The connecting member 25 can be made by various alternatives, as described below, depending on the relative positioning of the two light-emitting modules 11 in question.

[0039] 2 to 6 show an exemplary embodiment of the lighting device 7 according to the first embodiment. The lighting device 7 includes various components as described above and has at least two light-emitting modules 11, hereinafter referred to as a first module 11a and a second module 11b, which are supported by the first intermediate support 17a and the second intermediate support 17b, respectively, of the intermediate support 17 described above. The modules 11a and 11b are arranged in the headlamp 3 so that they are at least partially overlapped, in particular along a direction perpendicular to their pivot axes 2000, in particular along the vertical direction Z. In other words, at least one vertical axis passes through the first module 11a and the second module 11b. In this example, the second module 11b is located lower than the first module 11a along the vertical direction Z.

[0040] In the illustrated example, the first module 11a may be a low beam lamp, while the second module may be a high beam lamp. Alternatively, the first and second modules may be two beams of the same lamp, a low beam lamp. For example, the first module 11a may form a beam with a flat or substantially flat upper cutoff, corresponding to a "flat" beam, and the second module 11b may form a beam with an upper cutoff having an oblique portion, corresponding to a "kinked" beam, or vice versa.

[0041] In such an embodiment, the main mounting plate 9 comprises at least one frame 27 configured to support the second intermediate support 17b and the second module 11b in a surrounding manner. The frame 27 is particularly closed and is made up of a plurality of branches 29, which may be at least partially straight and / or curved. The main mounting plate 9 further comprises two members 31, which are integrally formed with the frame 27, extend upward, and are configured to support the first intermediate support 17a and the first module 11a. As a result, when the headlamp 3 is in position on the vehicle 1, the first intermediate support 17a and / or the first module 11a extend at least partially between the two members 31.

[0042] The frame 27 and the member 31 advantageously form an integral assembly, i.e., they cannot be separated from one another without damaging or destroying them. It is noted that the shape of the illustrated main mounting plate is in no way limiting. Thus, the shape can be inverted, for example, so that the frame 27 surrounds the first module 11a, or so that the member 31 extends downward. Similarly, according to an alternative not shown, the member 31 can be added and fixed to the frame 27, for example, by screwing or welding. Again, as an alternative, the frame 27 can be shaped and / or sized to directly support the first and second intermediate supports 17a, 17b.

[0043] As disclosed above, the main mounting plate 9 is movable about a first, here vertical, adjustment axis 1000. It supports two rotation means 15 defining a pivot connection that allows it to move relative to the headlamp housing 5 about the first adjustment axis 1000. These two rotation means 15 can in particular be arranged at opposite vertical parts or ends of the main mounting plate 9, for example at the free ends of posts 33 connected to the frame 27.

[0044] The intermediate supports 17 are movably mounted, in particular pivotably mounted, relative to the main mounting plate 9. Each intermediate support 17 comprises, for example, a plate 35 on which the light emitting module 11 in question is at least partially arranged, and two arms 37 connected to the plate 35 and extending on either side thereof.

[0045] By way of non-limiting example, the first intermediate support 17a is substantially H-shaped. The plate 35 extends at least partially in a horizontal or substantially horizontal plane. A first pivot point 19a, hereinafter referred to as the first pivot axis 2000a, contributing to the definition of the pivot axis 2000 of the first light-emitting module 11a, is included in the first arm 37a. A second pivot point 19b is included in the second arm 37b. The pivot point 19a in particular comprises a head configured to interact with a complementary-shaped connecting means 39 included in the main mounting plate 9. In this example, the first intermediate support 17a is fixed to the member 31 of the main mounting plate 9. Similarly, the pivot points 19a, 19b of the first intermediate support 17a are aligned or substantially aligned in a plane parallel to the ground.

[0046] Similarly, the second intermediate support 17b comprises a plate 35 and two arms 37, which in the example shown extend on either side of said plate 35 along the lateral direction Y and the vertical direction Z. Each arm 37 includes a pivot point 19a, 19b as described above, which is formed by a connection with the main mounting plate 9 made in the frame 27. In particular, the arms 37 of the second intermediate support 17b interact with two opposite branches 29 of the frame 27.

[0047] Similarly, the first intermediate support 17a and the second intermediate support 17b are indirectly connected to each other via a connecting member 25. In particular, the connecting member 25 is connected to a first connection zone 41 included in the first intermediate support 17a and a second connection zone 43 included in the second intermediate support 17b.

[0048] According to the particular exemplary embodiment shown, the first module 11a and the second module 11b are offset relative to one another along the longitudinal direction X. In other words, the modules 11 are offset along a direction perpendicular to the first adjustment axis 1000 and to the pivot axis. For example, such an offset can be evaluated at a pivot point specific to each of the modules 11 or at the front face. In this example, the second module 11b is located further forward than the first module 11a along the longitudinal direction, and the second connection zone 43 is offset toward the front relative to the first connection zone 41 along the longitudinal direction. Such positioning depends in particular on the shape, in particular the curve, of the outer lens of the headlamp 3, and thus on the design of the vehicle.

[0049] The connecting element 25 may comprise a rod 45, as shown in FIGS. 2 to 4 . The rod 45 is indirectly connected to the first module 11 a via a first intermediate support 17 a in the first connection zone 41 and to the second module 11 b via a second intermediate support 17 b in the second connection zone 43. To limit the footprint generated by the connecting element 25 and to accommodate both vertical and longitudinal offsets, the rod 45 is advantageously curved. It comprises, in particular, a straight or substantially straight intermediate portion 47 and two opposite end portions 49, each intended to be attached to one of the intermediate supports 17 and each connected to the intermediate portion 47 by an elbow 51. In particular, the first elbow 51 a extends near the first connection zone 41, while the second elbow 51 b extends near the second connection zone 43.

[0050] The rod 45 is in particular S-shaped or substantially S-shaped, i.e. the two end portions 49 of the rod 45 extend transversely to the intermediate portion 47 and point in opposite directions along the same direction. Here, when the lighting device 7 is assembled and placed in a vehicle, the intermediate portion 47 extends vertically or substantially vertically, while the end portions 49 extend transversely, in particular perpendicularly thereto. In the example shown, the first end portion 49 of the rod 45 connected to the first intermediate support 17a extends towards the rear, while the opposite second end portion 49 extends towards the front.

[0051] Each end portion 49 carries a connecting element 53 configured to interact by a complementary shape with a receiving element included in one of the intermediate supports 17. The connecting element takes the form of an at least partially circular head so as to form a ball-joint connection with the different intermediate supports 17, as can in particular be seen in Figure 3.

[0052] Each of the intermediate supports 17 is thus connected to another component of the lighting device at at least three "points" or zones. In the connection made between the pivot point 19 and the main mounting plate 9, the center of said connection remains substantially fixed in space relative to an initial, i.e. rest, position. Conversely, the center of the connection existing between one of the connection zones 41, 43 and the connecting member 25 is moved along the direction of extension of the intermediate portion 47, in this example along the vertical or substantially vertical direction Z.

[0053] As mentioned above, in a given intermediate support 17, two pivot points 19 are aligned so as to define a pivot axis 2000 of the module 11 and of the support in question. The coupling zone specific to the intermediate support 17 in question is offset relative to the pivot axis 2000, in particular along the direction defined by the first adjustment axis 1000, i.e. in this case the vertical direction Z.

[0054] Preferably, the connection zones 43, 44 are located in one of the arms 37 of the intermediate support 17 at a non-zero distance from the pivot point 19 included in this same arm 37. For example, as shown in Figure 4 or 5 in the case of the first intermediate support 17a, the first arm 37a comprises a first pivot point 19a and a first connection zone 41, which are located in particular at the opposite end portion of the arm 37. Conversely, the second pivot point 19b is located in a more central position in the second arm 37 along the vertical direction Z.

[0055] Similarly, in the second intermediate support 17b, the first arm 37a comprises a first pivot point 19a of the second pivot axis 2000 and a second connection zone 43, the latter preferably having an end position within the first arm 37a.

[0056] Furthermore, within the lighting device 7, the first connection zone 43 and the second connection zone 44 are preferably arranged so that they are aligned or substantially aligned along the direction determined by the first adjustment axis 1000, i.e. in this case the vertical direction Z.

[0057] Furthermore, optionally but preferably, the distance along the direction determined by the first adjustment axis 1000 separating the pivot axis 2000 of one of the two modules 11 from the first coupling zone 41 is the same as the distance separating the pivot axis 2000 of the other of the two modules 11 from the second coupling zone 43. Thus, in the example shown, the first pivot axis 2000a of the first module 11a is separated from the first coupling zone 41 by a distance 55 determined along the vertical direction Z, which is equal to the distance 57 separating the second pivot axis 2000b from the second coupling zone 43. Such positioning of the coupling zones 41, 43 is intended in particular to reduce variations in the tilt angle between the two modules 11 when a movement of one of the two modules is transmitted to the other of said modules.

[0058] In the illustrated exemplary embodiment, the second adjustment means 23 is indirectly connected to the first and second modules 11a, 11b via the second intermediate support 17b. In particular, the second adjustment means 23 is connected to the second intermediate support 17b at a second operating point P2, which is included in one of the arms 37 of said support. More specifically, the second operating point P2 is located on the second arm 37b at a non-zero distance from the pivot axis 2000b along the vertical direction Z. Thus, in response to a received automatic or manual vertical adjustment command, the second adjustment means 23 pulls or pushes the second intermediate support 17b at the second operating point P2 to pivot the second intermediate support 17b, and thus the second module 11b, in one direction or the other about the second pivot axis 2000b in order to direct the beams emitted by each of these modules 11a, 11b further or closer to the roadway.

[0059] Optionally, in order to ensure an optimal transmission of the movement of one module 11 to the other, the lighting device 7 can comprise at least one guide means 59 for guiding the connecting member 25. The at least one guide means 59 can be at least partially connected to an intermediate support 17 specific to one of the two modules 11 and / or at least partially connected to an intermediate support 17 specific to the other of the two modules 11.

[0060] For example, as shown in Figure 4 or 5, the guide means 59 can comprise a fin 61 connected to the first intermediate support 17a. The fin 61 comprises an attachment portion 63 connected to the first arm 37a of the first intermediate support 17a and a guide portion 65 that can receive and / or interact with the coupling member 25. The attachment portion 63 and the guide portion 65 can in particular extend transversely, for example perpendicularly, to each other. The fin 61 can also be added and fixed to the first intermediate support 17a or can be formed integrally therewith.

[0061] The guide portion 65 is configured to limit the movement of the rod 45 along at least one direction transverse, in particular perpendicular, to the direction of extension of the rod 45 and / or the direction of the first adjustment axis 1000. In this example, the guide means 59 contributes to optimizing the movement of the rod 45 along the vertical direction Z, while limiting its movement in both directions, in particular along the transverse direction Y. Here, the guide portion 65 has a substantially open U-shape bordering an opening that can receive all or part of the connecting member 25, in particular here the middle portion 47 of the rod 45. In the example shown, it has a shape complementary to the rod 45 and limits its movement only in one direction along the longitudinal direction X, here towards the rear of the vehicle 1. According to an alternative not shown, the guide portion 65 can also be closed, i.e. its opening is bounded by a continuous edge, so that the movement of its blocking means is limited in both directions along the longitudinal direction X.

[0062] The fin 61 is arranged near the first coupling zone 41. As a result, the guide portion 65 extends transversely to the vertical direction Z in the direction of the coupling element 25. Preferably, the guide portion 65 interacts with the straight intermediate portion 47 of the rod 45.

[0063] Advantageously, the guide means 59 can be configured to limit the movement of the connecting member 25 along three directions. In particular, the fins 61 of the guide means 59 can be configured to form stops for the connecting member 25 along the transverse direction Y and along all or part of the longitudinal direction X, as described above, and along the direction of movement of the rod 45, here the vertical direction Z. For example, the guide means 59 forms a stop in at least one direction, along the vertical direction Z, for at least one of the elbows 51 of the rod 45. Such an arrangement makes it possible to limit the movement of the light-emitting module 11 in particular.

[0064] Alternatively or additionally, for example as shown in Figure 6, the guide means 59 can comprise a fin 61 connected to the second intermediate support 17b. Such a fin 61 is similar to the fin described with reference to the first intermediate support 17a, and the above description applies mutatis mutandis. Here, it extends in the vicinity of the second connection zone 43. In the specific case of an S-shaped rod, the fin 61 of the second intermediate support 17b can extend, for example, towards the front of the vehicle 1.

[0065] According to an alternative embodiment not shown, the guide means 59 advantageously comprises a plurality of fins 61. In particular, a first fin 61 can be connected to the first intermediate support 17a, while a second fin 61 can be connected to the second intermediate support 17b, each in the vicinity of one of the connection zones 41, 43. And said fins 61 can in particular be oriented in opposite longitudinal directions, for example one towards the front and the other towards the rear of the vehicle.

[0066] Thus, when a user wants to adjust the height of the light beam emitted by the two modules 11a, 11b, they control the tilt of the second module 11b via the second adjustment means 23. The second adjustment means 23 applies a force to the second actuation point P2 in order to tilt the second intermediate support 17b, in particular its plate 35, and thus the second module 11b, around the second pivot axis 2000b. For example, such a force is exerted along the longitudinal direction X, pulling or pushing the support. At the same time, the connecting member 25 rigidly connected to the second intermediate support 17b is actuated, so that the tilting movement performed by the second module 11b is transmitted to the first module 11a. For example, when the second module 11b tilts upward, the rod 45 translates along its direction of extension along the vertical direction Z, here perpendicular to the pivot axes 2000a, 2000b. Thus, the position of the rod 45 is lowered so that the intermediate portion 47 descends along the vertical direction Z. The movement of the rod 45 along the lateral direction and at least part of the longitudinal direction is limited by the guide means 59, so that the movement is transmitted as precisely as possible. This movement is transmitted to the first module 11a, lowering the connecting element 53 in the second coupling zone 43 and tilting the second module 11b upward about the second pivot axis 2000b. The coupling member 25 thus enables the first light-emitting module 11a to be tilted in the same pivotal direction and with the same tilting degree as the second light-emitting module 11b. In this way, the two light-emitting modules 11 are simultaneously adjusted by tilting about their respective pivot axes 2000a, 2000b, and a single vertical adjustment command is transmitted uniformly to the two modules 11.

[0067] 7-9 show a second embodiment of a lighting device 7 according to the invention, in which the relative positioning of two light-emitting modules 11 connected to each other by at least one connecting member 25 differs from that described above. Such an embodiment employs the principles of the first embodiment, and therefore the above description applies mutatis mutandis, unless otherwise stated. For clarity, the same reference numerals are used for identical or substantially identical components. The reference numerals for the light-emitting modules and intermediate supports are incremented by 100 to distinguish their positional relationship from the first embodiment; therefore, the module is designated by reference numeral 111 and the intermediate support is designated by reference numeral 117.

[0068] The second embodiment differs from the first embodiment in particular in that the two light-emitting modules 111 are arranged side by side along a direction parallel to the pivot axis 2100, here the horizontal or lateral direction Y. In other words, the first module 111a and the second module 111b extend at least partially opposite each other along the lateral direction Y; therefore, the same horizontal plane containing the longitudinal direction X and the lateral direction Y passes through the first module 111a and the second module 111b. By way of example, the first module 111a can in particular be a low-beam lamp, and the second module 111b can be a high-beam lamp.

[0069] Similar to the disclosure above with reference to the first embodiment, the two light emitting modules 111 are also offset relative to each other along a direction perpendicular to the first adjustment axis 1000 and to the pivot axis. In this example, the second module 111b is offset forward relative to the first module 111a along the longitudinal direction X.

[0070] As in the first embodiment, the main mounting plate 9 includes at least one frame 27. In particular, in the illustrated example, the main mounting plate 9 includes a first frame 27a and a second frame 27b connected to each other by a common central branch 67. Each of the first frame 27a and the second frame 27b is configured to receive at least one light-emitting module 111 of the two modules 111 to be connected. In this example, the first frame 27a receives the first module 111a and the first intermediate support 117a, while the second frame 27b receives the second module 111b and the second intermediate support 117b.

[0071] In the following description, the first light-emitting module 111a and the first intermediate support 117a may adopt all or some of the features related to the second module 111b and the second intermediate support 17b, respectively, as described above with reference to the first embodiment. The first intermediate support 117a comprises a plate 35 and two arms 37. Each arm 37 comprises a pivot point 19 formed by connection with a main mounting plate 9, which here is manufactured on the first frame 27a and defines a first pivot axis 2100a of the first intermediate support 117a by extension of the first module 111a. In particular, the arms 37 of the first intermediate support 117a interact with two opposite branches 29 of the first frame 27a.

[0072] According to a non-limiting exemplary embodiment, the second intermediate support 117b takes the form of a closed frame including a plurality of segments 69. Here, "segment" is given to mean a part of a whole. For example, the second intermediate support 117b can extend at least partially in continuation of the second frame 27b of the main mounting plate 9 along the longitudinal direction X. Alternatively, the second intermediate support 117b can have an open shape, e.g., a U-shape or substantially U-shape. The second intermediate support 117b is arranged along the longitudinal direction X, i.e., along a direction perpendicular to the different pivot axes 2100 and to the first adjustment axis 1000, so that the main mounting plate 9 is interposed between the first intermediate support 117a and the second intermediate support 117b. The second intermediate support 117b has two pivot points 19 that define a second pivot axis 2100b of the second intermediate support 117b and of the second module 111b. The pivot point 19 is located on the opposite segment 69 of the second intermediate support 117b.

[0073] The first module 111a and the second module 111b are connected to one another via a connecting element 25. In this embodiment, the connecting element 25 comprises a slider 71 connected to a first connection zone 41, comprised in the first intermediate support 117a, and to a second connection zone 43, comprised in the second intermediate support 117b. In particular, the slider 71 comprises a bar 73, the two opposite ends of which support an element 53 for connection to one of the intermediate supports 117. The bar 73 is connected to the first intermediate support 117a and to the second intermediate support 117b via ball joint connections connected to the first connection zone 41 and to the second connection zone 43, in particular as described above with reference to the rod 45.

[0074] The bar 73 is also configured to interact with the main mounting plate 9 in order to be moved laterally, in particular perpendicularly, relative to the first adjustment axis 1000 and to the pivot axis 2100. In particular, the bar is moved along or substantially along the longitudinal direction X. In particular, the bar 73 has a shape complementary to a rail 75 included in the main mounting plate 9. For this purpose, it comprises at least one rib 77 configured to interact with at least one groove 79 included in the rail 75.

[0075] The slider 71 is preferably arranged adjacent to the second adjusting means 23. It extends substantially along the longitudinal direction X between the first pivot axis 2100a and the second pivot axis 2100b. The rail 75 is in particular integrated into the central branch 67, which in the example shown is common to the two frames 27a, 27b of the main mounting plate 9. Likewise, the slider is connected to or bears on the second actuation point P2. In particular, the bar bears on the second actuation point P2.

[0076] 8 and 9 is controlled to translate by command instructions coming from the second adjusting means 23, which may for example comprise a motor. Grooves 79 in the rails 75 are configured to guide the bar 73 in the appropriate translation. Relative movement of the bar 73 of the slider 71 with respect to the main mounting plate 9 simultaneously exerts forces on the first connection zone 41 and on the second connection zone 43, which causes tilting of the first intermediate support 117a, the second intermediate support 117b, and thus the light-emitting modules 111 they support, about their own pivot axes 2100.

[0077] In order to ensure the same inclination of the first module 111a and the second module 111b, the positions of the connection zones 41, 43 are determined, in particular along the direction determined by the first adjustment axis 1000, so that the distance 83 separating the first pivot axis 2100a of the first module 111a from the first connection zone 41 and the distance 85 separating the second pivot axis 2100b of the second module 111b from the second connection zone 43 are identical.

[0078] Thus, as described above, when a user wants to adjust the height of the light beams emitted by the two modules 111, they command the tilt of the first light-emitting module 111a via the second actuation point P2. The second adjustment means 23 applies a force to the second actuation point P2 to tilt the first intermediate support 117a, and thus the first module 111a, around the first pivot axis 2100a. For example, such a force may be exerted along the longitudinal direction, pulling or pushing the support. At the same time, within the slider 71, the bar 73 rigidly connected to the first intermediate support 117a is actuated and moved relative to the rail 75 of the main mounting plate 9, and such movement is transmitted to the second module 111b. For example, when the first module 111a is tilted upward, the bar 73 simultaneously translates rearward along the longitudinal direction, thereby pulling the second module 111b to tilt it in the same pivotal direction and with the same degree of tilt as the first light-emitting module 111a.

[0079] Finally, Figures 10 to 12 show a third embodiment in which the lighting device 7 comprises three light-emitting modules. For clarity, unless otherwise stated, the same reference numerals are used for components that are identical or substantially identical to those in the first or second embodiment. The reference numerals for the light-emitting modules and intermediate supports are increased by 200 from the first embodiment.

[0080] In this embodiment, the first light emitting module 211a and the second light emitting module 211b are included in a subassembly that can be configured according to the first embodiment. The third light emitting module 211c is movably mounted to the main mounting plate 9 via a third intermediate support 217c at two adjustable pivot points 19 that define a third pivot axis 2200c unique to the third module 211c and that are parallel to the pivot axes of the first module 211a and the second module 211b. In such a lighting device 7, the first adjustment means 13 advantageously allows simultaneous movement of the three modules 211 about the first adjustment axis 1000 via the main mounting plate 9, while at least the modules 211 included in the subassembly that are connected together by the coupling member 25 can be simultaneously moved via the second adjustment means 23.

[0081] In the particular embodiment shown, the first light emitting module 211a and the second light emitting module 211b form a first subassembly 87 configured in accordance with the first embodiment, while the second module 211b and the third module 211c form a second subassembly 89 configured in accordance with the second embodiment described above. Accordingly, the above description applies mutatis mutandis to each of said subassemblies, particularly with regard to the relative positioning of the light emitting modules and connecting members described. In particular, in such exemplary embodiment, the second light emitting module 211b is common to the first subassembly 87 and the second subassembly 89. Similarly, the main mounting plate 9 is common to the two subassemblies.

[0082] In the illustrated example, the first module 211a and the second module 211b emit two beams that together form a low beam. For example, the first module can form a beam with a flat or substantially flat upper cutoff corresponding to a "flat" beam, and the second module can form a beam with an upper cutoff having an angled portion corresponding to a "kinked" beam. The third module 211c emits a beam that forms a supplemental high beam, which complements the low beam formed by the first module 211a and the second module 211b. The superposition of the beams formed by the first light-emitting module 211a, the second light-emitting module 211b, and the third light-emitting module 211c thus forms the high beam.

[0083] The second light-emitting module 211b is connected to the first module 211a by a connecting member 25, referred to as the first connecting member 25a, and comprising the above-mentioned rod 45. The second module 211b is further connected to the third module 211c by another connecting member 25, referred to as the second connecting member 25b, and comprising the above-mentioned slider 71. The three modules 211 are thus directly or indirectly connected to each other, such that adjustment of one of said modules 211 via the second adjustment means 23 thus enables simultaneous movement of the three modules 211 about their respective pivot axes 2200. It is noted here that the first light-emitting module 111a and the first intermediate support 117a of the second embodiment correspond to the second light-emitting module 211b and the second intermediate support 217b, respectively, while the second light-emitting module 11b and the second intermediate support 17b of the first embodiment correspond to the third light-emitting module 211c and the third intermediate support 217c of this embodiment.

[0084] The main mounting plate 9 can particularly employ all or some of the features described above with reference to the first and second embodiments. In this example, the main mounting plate includes a first frame 27a from which the second module 11b extends, a second frame 27b connected to the first frame 27a and from which the third light-emitting module 211c extends, and two members 31 connected to the first frame 27a and supporting the first light-emitting module 11a.

[0085] Preferably, the first adjusting means 13 is arranged on the main mounting plate 9 at a non-zero distance from the first adjusting axis 1000, in particular near the third light-emitting module 211c. The first adjusting axis 1000 is also preferably centrally or substantially centrally arranged within the main mounting plate 9 along a direction parallel to the pivot axis 2100, i.e., here along the lateral direction Y. The first adjusting axis 1000 is arranged, in particular, between at least two of the three light-emitting modules 211 along the lateral direction Z. Here, the first adjusting axis 1000 is interposed between the first module 211a, the second module 211b, and the third module 211c.

[0086] Similarly, the second adjustment means 23 are arranged near the central zone of the main mounting plate 9 along the transverse direction Y, in particular on the central branch 67, near the second connecting member 25b. Furthermore, the second adjustment means 23 are arranged such that they are interposed along the direction determined by the first adjustment axis 1000, here along the vertical direction, between at least two pivot axes 2200 specific to two separate modules 211. In this example, the second adjustment means are interposed between the first pivot axis 2200a and the second and third pivot axes 2200b, 2200c.

[0087] In particular, the adjustment device is configured as follows: - in the first connecting element 25a, the first pivot axis 2200a of the first module 211a is spaced from the first connecting zone 41′ by a distance 55 determined along the vertical direction Z, the distance 55 being equal to the distance 57 spacing the second pivot axis 2000b from the second connecting zone 43′ of the first connecting element 25a; and - In the second connecting member 25b, the positions of the connecting zones 41'', 43'' are determined in particular such that, along the direction determined by the first adjustment axis 1000, the distance 83 separating the second pivot axis 2200b of the second module 211b from the first connecting zone 41'' is the same as the distance 85 separating the third pivot axis 2200c of the third module 211c from the second connecting zone 43''.

[0088] Likewise, said distances 55, 57, 83, 85 are preferably equal or substantially equal. Such positioning of the respective specific coupling zones of each coupling member 25 is aimed in particular at reducing variations in the degree of tilt between the three modules 211.

[0089] As described above, when a height adjustment of the light beam emitted by a different module 211 is commanded, the second adjusting means 23 thereby exerts a force on the second operating point P2, in particular on the intermediate support 217b of the second module 211b, causing tilting of the second module 211b around the second pivot axis 2200b. Simultaneously, as described above, the bar 73 rigidly connected to the third intermediate support 217c is driven to move relative to the rail 75 of the main mounting plate 9. The third module 211c is then tilted to the same extent as the second module 211b. In parallel, the tilting of the second module 211b drives the first linking member 25a rigidly connected to the first intermediate support 217a. The movement of the rod 45 is transmitted to the first module 211a, and the connection means in the second coupling zone 43' causes the first module 211a to tilt downward in the same pivot direction and at the same inclination as the second and third light-emitting modules 211b, 211c. In this way, the light-emitting modules 211 are adjusted simultaneously by tilting about their respective pivot axes 2000, and a single adjustment command is transmitted uniformly to the three modules 211.

[0090] According to an alternative exemplary embodiment to the third embodiment (not shown), the lighting device 7 includes three light-emitting modules, of which a first and a second light-emitting module are included in a subassembly configurable according to the second embodiment described above. The third light-emitting module is movably mounted on the main mounting plate 9 via intermediate supports at two pivot points defining a pivot axis specific to the third light-emitting module and parallel to the pivot axes of the first and second modules. The above explanations given in particular with reference to the third embodiment also apply mutatis mutandis to this alternative. In particular, similar to the above explanations, the lighting device 7 is advantageously configured such that the first adjustment means 13 allows simultaneous movement of the three modules via the main mounting plate 9 about the first adjustment axis 1000, and the second adjustment means 23 allows simultaneous movement of at least two of the three modules about their own pivot axes.

[0091] The lighting device 7 according to the invention therefore allows simultaneous horizontal and vertical adjustment of multiple light emitting modules 211 via at least one connecting member 25. The lighting device 7 according to the invention is advantageously suitable for limited spaces, in particular at the front end of a vehicle 1, and the proposed solution results in a reduced footprint.

[0092] Furthermore, regardless of the embodiment implemented, at least one module of the plurality of modules can be provided with micro-adjustment means 91 specific to said module, allowing its vertical and / or horizontal adjustment, in other words, each around its own pivot axis or around an axis parallel to the first adjustment axis 1000. Micro-adjustment is intended to mean an adjustment with a small amplitude, which is not transmitted to any other module of the plurality of modules connected to the module in question. By way of non-limiting example, such an adjustment can be of the order of ±1°. In this example, in the third embodiment, a third module 211c is provided with such micro-adjustment means 211c, independently of the other two. In particular, the micro-adjustment means 91 is provided at the pivot point 19 of the module in question. In this way, activation of the micro-adjustment means 91 allows for independent adjustment of the position of that module, and thus of the alignment of the emitted light beam, to which it is connected, independently of the other modules of the plurality of modules to which it is connected. It is noted that one or more micro-adjustment means 91 may also be integrated into at least one of the modules, as described with reference to the first or second embodiment.

[0093] However, the invention is not limited to the means and arrangements described and illustrated herein, but also extends to any equivalent means or arrangements and any technically functional combinations of such means, provided that they ultimately perform the functions described and illustrated in this document.
