    [0001] The invention relates to the field of lighting of motor vehicles. It relates, more specifically, a lighting device for a motor vehicle. On modern vehicles tend to be generalized devices to enhance the lighting so as to improve efficiency, range, aesthetics, or to limit the glare of third parties. In particular, in recent years, an increasing number of vehicles (for the moment mainly at the premium level but the descent in range has already begun) were equipped with daytime running lights, intended to increase the visibility of the vehicle and which automatically light up when the ignition is touched. Similarly, directional lights have been proposed, which allow for example to illuminate the sides of the road or to adapt the main direction of lighting changes of direction of the vehicle. A lighting device is thus known comprising: - a chassis; an optical lens comprising a frame and a lens secured to the frame, the lens having a front diopter and an opposing rear diopter connected by a wafer, the frame being rotatably mounted relative to the frame; a light block provided with a main light source; and a mechanism for driving the optics in rotation, suitable for placing the optics in a so-called road orientation in which the front diopter is turned towards a so-called forward direction. Such a device, particularly known from FR 2 973 861, provides an adaptive road lighting according to the driving conditions, but it is not designed to provide a signaling lighting. [0007] Conventional lights generally separate the road lighting and signaling functions, to the detriment of the compactness of the headlight blocks, to the point that, in order to refine their aesthetics, the manufacturers now offer vehicles having headlight units dedicated to road lighting and headlight units dedicated to signaling lighting. A first objective is to provide a lighting device capable of providing sometimes a road lighting sometimes a lighting signaling. A second objective is to make more compact lighting devices for motor vehicles. For this purpose, it is proposed, in the first place, a lighting device for a motor vehicle, which comprises: a chassis; an optical system comprising a frame and a lens integral with the frame, the lens having a front diopter and an opposing rear diopter connected by a wafer, the frame being rotated relative to the frame, the optic being provided with a light source secondary, able to illuminate the edge of the lens; a light block provided with a main light source; a mechanism for driving the optics in rotation, capable of placing the optics in a so-called road orientation in which the front diopter is turned towards a so-called forward direction, this driving mechanism being arranged to place the optics according to a so-called signaling orientation in which the wafer is turned forward. Various additional features may be provided, alone or in combination: the secondary light source is mounted in the lens. the secondary light source is mounted at a distance from the wafer, the diopters forming a waveguide for channeling the light flux coming from the secondary light source towards the wafer; the light block comprises a reflector defining a reflective concave inner face opposite which the main light source is placed; in the road orientation, the rear diopter of the lens is placed facing the inner face of the light block; the signaling orientation is angularly offset, with respect to the road orientation, by an angle of approximately 180 °; the device comprises a frame mounted to rotate relative to the frame about a first vertical axis; the optic is rotatably mounted relative to the frame about a second horizontal axis; the optic is mounted in rotation with respect to the light block around a third horizontal axis spaced from the second horizontal axis; the drive mechanism comprises a rod provided with a shaft by which the rod is rotatably mounted relative to the frame about a fourth vertical axis spaced from the first vertical axis, and a lever bent with respect to the shaft , the lever of the rod being coupled to the light unit by a ball joint. - The device further comprises a motor coupled to the drive mechanism. It is proposed, secondly, a headlight block for a motor vehicle, which incorporates a lighting device as presented above. It is proposed, thirdly, a motor vehicle equipped with such a headlight block. Other objects and advantages of the invention will become apparent in the light of the description of an embodiment, given below with reference to the accompanying drawings in which: Figure 1 is a perspective view showing a vehicle automobile equipped with a headlight unit incorporating a mobile lighting device; Figure 2 is a perspective view showing a moving lighting device in a road position; - Figure 3 is a longitudinal sectional view of the lighting device of Figure 2, in the road position; Figures 4 and 5 are similar views in perspective illustrating the reversal of the lighting device to a signaling position; FIG. 6 is a perspective view showing the lighting device of FIG. 2 in its signaling position; Figure 7 is a longitudinal sectional view of the lighting device of Figure 6, in its signaling position; FIGS. 8A, 8B and 8C are front views illustrating three positions of the illumination device to allow light scanning according to the orientation of the vehicle; Figs. 9A, 9B and 9C are top views of the illuminator in the respective positions of Figs. 8A, 8B and 8C; Fig. 10 is a perspective view illustrating the light scan, as projected on a flat surface; Figure 11 is a view similar to Figure 6, illustrating a second embodiment; Figure 12 is a view similar to Figure 7, illustrating the lighting device in its second embodiment; FIG. 13 is a perspective view showing the lighting device in its road orientation, and illustrating an electric circuit for powering a light source carried by the optical unit; Fig. 14 is a perspective view showing the lighting device of Fig. 13 in its signaling orientation; Figure 15 is a partial side view of the lighting device in its road orientation, illustrating an alternative embodiment of the electrical circuit; Fig. 16 is a view similar to Fig. 16, in the signaling orientation; Figure 17 is a perspective view illustrating an assembly comprising a plurality of coupled lighting devices. [0002] FIG. 1 shows a vehicle 1 equipped on one front with at least one headlight unit 2 incorporating at least one mobile lighting device 3. It is defined with respect to the vehicle 1 (and therefore with respect to the headlight block) an orthogonal reference XYZ comprising three axes perpendicular two by two, namely: an axis X, defining a longitudinal direction, horizontal, coincides with the direction The general direction of movement of the vehicle is a Y axis, defining a transverse, horizontal direction which along the X axis defines a horizontal XY plane, a Z axis, defining a vertical direction, perpendicular to the horizontal XY plane. The lighting device 3 is arranged to adopt several configurations; it comprises, in the first place, a chassis 4 which, when the headlight unit 2 is mounted on the vehicle 1, is fixed relative thereto. The shape of the chassis 4 is arbitrary. In the drawings, the frame 4 is shown in the form of a plate for the purpose of clarity and simplification of the presentation. The lighting device 3 comprises, secondly, a moving crew 5 relative to the chassis 4. The mobile crew 5 comprises a frame 6 mounted in rotation relative to the frame 4 around a first Al axis. In what follows, it is conventionally decreed, for the sake of clarity, that this first axis Al is vertical (along Z). This orientation corresponds to a preferred embodiment. However, this first axis Al could be oriented in any way in the vertical plane YZ. In particular, the first axis Al could be horizontal (following Y). According to a preferred embodiment illustrated in the figures, the armature 6 is in the form of a stirrup comprising a main shaft 7 defining the first axis Al vertical, a substantially horizontal core 8 secured to the main shaft 7 and two vertical arms 9 extending on either side of the core 8, from lateral ends thereof. In the illustrated orientation, the arms 9 open downward. However, this orientation is arbitrary, and the arms 9 could open upwards (in other words, maintaining the verticality of the axis Al, we could return the entire crew 5 mobile). According to an embodiment illustrated in particular in Figure 3, the attachment of the main shaft 7 on the frame 4 is formed by means of a nut 10 screwed on an upper portion of the shaft 7, the frame 4 being sandwiched between the nut 10 and a shoulder 11 formed in a lower part of the shaft 7. [0009] The mobile assembly 5 also comprises an optic 12 comprising a frame 13 and a lens 14 secured to the frame 13 The lens 14 is made of a transparent material. It is preferably a synthetic plastic material, for example a polyacrylate, which has the advantage of offering good optical properties (including good transparency) and mechanical properties (including good rigidity). The lens 14 has a front diopter 15 (in this case convex) which defines for the lens 14 a primary optical axis 01, and a rear diopter 16 (in this case concave) opposite. The front diopter 15 and the rear diopter 16 are connected by a wafer 17 which forms a lateral diopter defining a secondary optical axis 02. In the illustrated example, the contour of the lens 14 is substantially rectangular, but this form is given for illustrative purposes only. According to a preferred embodiment, the dioptres 15, 16 are arranged so that the primary optical axis 01 and the secondary optical axis 02 are perpendicular and jointly extend in a vertical plane also containing the first axis Al of rotation of the frame 6. The frame 13 is preferably metallic; it comprises two lateral branches 18 (which, as in the example illustrated, can be bent), connected by a transverse bar in which the lens 14 is anchored. [0013] With its branches 18, the frame 13 is mounted in rotation relative to the frame 6 about a second horizontal axis A2. This second axis A2 of rotation is for example formed by pivots (not shown) connecting the branches 18 to the arms 9 at one end thereof. Similarly, the second axis A2 extends to one end of the branches 18 opposite the transverse bar 19. The mobile equipment 5 comprises, moreover, a light block 20 provided with a main light source 21, mounted opposite the rear diopter 16 of the lens 14. This light block 20 comprises a reflector 22 defining a face 23 which is located to illuminate it, and an opposite convex outer face 24, the inner face 23 and the outer face 24 being connected by a wafer 25. [0015] The character reflective of the inner face 23 is for example provided by a silver coating 26. The main light source 21 is for example a gas bulb (typically halogen or xenon), or alternatively electroluminescent diode (s) or LED. As illustrated in the figures, and more particularly in FIG. 3, the reflector 22 comprises a bottom wall 27 and two lateral walls 28 which extend vertically, substantially parallel to one another, from one side to the other. on the other side of the bottom wall 27. The side walls 28 jointly define, opposite the bottom wall 27, an opening 29 through which the light emitted by the main light source 21 and reflected by the inner face 23 of the reflector 22 passes. [0018] As it is also seen in FIG. 3, the reflector 22 comprises an upper wall 30, possibly perforated, on which the main light source 21 is mounted to illuminate the inner face 23 of the reflector 22. [0019] The light block 20 is mounted in rotation, relative to the frame 13 of the optics 12, around a third horizontal axis A3 spaced from the second axis A2. On the reflector 22, the third axis A3 is on the side of the opening 29. On the frame 13, the third axis A3 extends in an intermediate zone between the end of the branches 18 and the transverse bar 19, preferably at the level of a bend formed by each branch 18. The rotation of the armature 6 around the first vertical axis A1 makes it possible to rotate the optic 12 (and thus the lens 14 and its primary optical axis 01) by relative to the chassis 4 around the first axis Al vertical. The rotation of the frame 13 about the second horizontal axis A2 also allows to rotate the optical 12 (and therefore the lens 14 and its primary optical axis 01) relative to the frame 4 about the second horizontal axis A2. The lighting device 3 comprises a mechanism 31 for driving the frame 13 in rotation, integrated with the mobile equipment 5 and which comprises means for coupling the rotation of the frame 6 around the first axis Al the rotation of the optics 12 around the second axis A2 to synchronize these two rotations. As we will see, this coupling is made here via the light block 20. The drive mechanism 31 comprises a rod 32 provided with a shaft 33 by which the rod 32 is rotatably mounted relative to the frame 4 about a fourth vertical axis A4 spaced from the first axis A1, and a lever 34 bent with respect to the shaft 33, this lever 34 being coupled to the light block 20 by a ball joint connection (hereinafter more simply referred to as a ball joint). According to one embodiment illustrated in the figures, the ball 35 comprises, on the one hand, a sphere 36 carried by the light block 20, and on the other hand an eyelet 37 with spherical seat 38 carried by the lever 34 the rod 32 and which cooperates with the sphere 36. This structure is given by way of example; it could be reversed without changing the operation. In the illustrated example, the sphere 36 is mounted on a portion 39 of the reflector 22 formed projecting on the outer face 24 thereof. The lever 34 preferably extends in a horizontal plane, but this configuration is not essential, the essential thing being that the anchoring of the rod 32 on the light block 20 is eccentric with respect to the first axis Al vertical rotation. To increase the angular movement of the assembly, the lever 34 of the rod 32 is preferably curved, as is clearly visible in particular in Figures 5 and 6. The device 3 further comprises a motorization 40 coupled to the armature 6 (or to the connecting rod 32) to rotate it about its axis A1 (respectively A4) according to particular predetermined rolling conditions, which will be specified below. According to a preferred embodiment illustrated in the figures, the motorization 40 is coupled to the armature 6. In the example illustrated, the motorization 40 comprises an output shaft 41 provided with a pinion 42 which meshes with a toothed gear wheel 43. of the main tree 7. In a so-called road configuration, illustrated in Figures 2, 3, 8B, 9B, 10 and 13, the mobile equipment 5 is arranged to provide road lighting along the primary optical axis 01. In this configuration: the optic 12 (and thus the lens 14) adopts a so-called road orientation, in which the second axis A2 and the third axis A3 extend transversely, parallel to Y, in the same plane vertical (parallel to YZ), and in which the front diopter 15 is rotated in a so-called forward direction (corresponding to a direction of movement of the vehicle 1), the primary optical axis 01 extending horizontally, parallel to the X axis whereas the secondary optical axis 02 extends substantially vertically (parallel to the Z axis); the end of the rod 32 bearing cup 37 extends farthest from the main shaft 7, that is to say from the first vertical axis Al, the inner face 23 of the reflector 22 extends opposite the diopter 16, so as to allow forward illumination parallel to the primary optical axis 01, as suggested by the dotted lines in FIG. 3, which materialize light rays coming from the light source 21. main and successively reflected by the inner face 23 of the reflector 22 and refracted by the lens 14 to the passage of the rear diopter 16 and the front diopter 15. Under the action of the motor 40, the main shaft 7 is rotated about the first axis Al vertical (arrow F1, Figures 4 and 5). This rotation causes the rotation of the optics 12 and the light block 20 around the first vertical axis Al. The sphere 36 is however constrained, by the ball 35, to describe a circular path in a horizontal plane (swept by the end of the lever 34), centered on the fourth vertical axis A4 (arrow F2, FIGS. 4 and 5) - and The rotation of the light block around the first vertical axis A1 consequently causes the sphere 36 to move on its circular path, which brings it closer to the first vertical axis Al and causes the proper tilting. the light block 20 about a horizontal axis passing through the sphere 36 and parallel to the axes A2 and A3 (arrow F3, Figures 4 and 5). This results in a thrust exerted by the light block 20 on the third axis A3 horizontal, which causes the tilting of the optical 12 around the second horizontal axis A2, around which the third axis A3 (and therefore the mount 13 ) is indeed obliged to move by describing a circular trajectory. It follows from this kinematics two joint rotations and synchronous optics 12 relative to the chassis 4, first around the first vertical axis A1 and secondly around the second horizontal axis A2. The rotation around the first vertical axis A1 can be carried out, from the road configuration, over an angular amplitude of 180 °, which places the mobile equipment in a so-called signaling configuration in which: armature 6 has made a half turn around its axis Al of rotation; the rod 32 has also performed a half-turn around its axis A4 rotation, which brings the eye 37 closer to the main shaft 7 (and therefore the first axis Al vertical); the optic 12 (and therefore the lens 14) has rotated a half-turn about the first vertical axis Al combined with a quarter turn rotation about the second horizontal axis A2, which places it in a so-called signaling orientation in which the wafer 17 is turned towards the front, the secondary optical axis 02 being horizontal and parallel to the axis X, while the primary optical axis 01 extends substantially vertically (parallel to the Z axis). This mobile architecture provides the following advantages: simplicity, thanks to the combination of the four axes A1, A2, A3, A4 rotation and the ball 35, efficiency, the relative movements of the frame 6, the block 20 light and optics 12 being precise, 25 lightness and compactness, thanks to the small number of parts and the presence of a single motor 40. [0037] In addition, this architecture allows for several functions. A first function is an alternation between a road lighting 30 and a signaling light. To achieve this function, the optic 12 is provided with a secondary light source 44, able to illuminate the wafer 17 of the lens 14. According to a preferred embodiment, the secondary light source 44 is mounted in the lens 14. More precisely, and as can be seen in particular in FIGS. 5 and 7, the secondary light source 44 is mounted at a distance from the wafer 17, for example in a curved edge 45 of the lens 14 which is extends between the branches 18, the dioptres 15, 16 forming a waveguide for channeling to the edge 17 the luminous flux coming from the secondary light source 44, as illustrated in FIG. 7, where it has materialized in dotted lines certain light rays coming from the secondary light source 44, reflected in grazing incidence by the front diopter 15 and the rear diopter 16 of the lens 14 and transmitted in the form of diffuse light through the wafer 17. [0041] Thus, sometimes, s the road configuration, directional lighting, powerful, directed along the primary optical axis 01 of the lens 14 and to illuminate the road in front of the vehicle 1, sometimes in the signaling configuration, diffuse lighting, relatively soft by the edge 17 of the lens 14, making it possible to produce a lantern signaling the position of the vehicle 1, for example by day, or to create, for example by association with other lighting devices 3, a light signature. The control of the rotation can be performed automatically by means of a brightness detector connected, via a computer, to the operator 40, and which according to the ambient light conditions place the device 3 in signaling configuration when the brightness is important (daytime signaling), or in road configuration when the brightness is low (night lighting or tunnel lighting). A second function is a light scan of the road environment (road, aisles, animals, pedestrians, etc.) according to the driving conditions, and in particular according to the orientation of the vehicle 1 (in particular according to the yaw , that is to say the rotation around the Z axis, that the vehicle 1 performs during changes of direction). For this purpose, the motorization 40 may be slaved to the orientation of the vehicle 1 and drive the moving crew 5 in one direction or the other around the first axis A1, to illuminate the lateral zones of the vehicle. the road environment. The amplitude of the movement may be limited (for example by a few degrees), as illustrated in FIGS. 8A, 8C, 9A, 9C, as well as in FIG. 10, where a fictitious plane perpendicular to the axis 01 is represented. primary optics in the optical path of the optics 12: in a solid line, the mobile crew in road configuration, and the beam produced by the lens 14, directed towards the front, in dotted lines, the lens 14 having has undergone a limited rotation, and the beam produced by it, shifted laterally in one direction or the other. In the example shown, the angular amplitude of the scan is of the order of ± 20 °, but this value is not limiting. [0045] A third function is a signaling function provided by the light block itself. For this purpose, the reflector 22 is made of an optically diffusing material, that is to say able to retransmit substantially in all directions, in a diffuse manner, a luminous flux that it receives. This type of opaline material is often referred to as opal, which, when illuminated, diffuses light by providing a milky effect. For example, the reflector 22 may be made of a transparent plastic material loaded with a pigment (in particular a white pigment) which renders the material translucent and diffusing without, however, rendering it opaque. As illustrated in Figure 12, the outer face 24 is covered with an opaque coating 46 which extends around a zone 47 called uncoated diffusion. When the reflector 22 is illuminated by the wafer 25 by means of a light source, the light is transmitted by the material of the reflector 22 being channeled between the coatings 26, 46 (shown in Figure 12 by thick lines), then broadcast by the broadcast zone 47. The illumination provided is of low or medium power; it is nevertheless sufficient to carry out a signaling function revealing the position of the vehicle 1, and / or an aesthetic function according to the contours of the diffusion zone 47. This can be modeled on a logo or an inscription characterizing for example a brand or a slogan. The production of the diffusion zone 47 can be achieved by masking during the application of the coating 46 on the outer face 24 of the reflector 22, by means of a mask around the diffusion zone 47, applied on the external face 24, or by removal of material (typically by etching, especially laser) after application of the coating 46. The lighting of the edge 25 of the reflector 22 can be achieved by a light source permanently mounted at However, according to a preferred embodiment, the illumination is provided by the secondary light source 44 carried by the optic 12, and the lens 14 is provided with a prism 48 arranged to transmit at least one part of the luminous flux from the source 44 secondary light. For this purpose, the prism 48 is positioned on the lens 14 so as to extend right to the edge 25 of the reflector when the mobile equipment 5 is in the signaling configuration, the optics 12 being in its signaling orientation. As can be seen in FIGS. 11 and 12, the prism 48 is formed in the mass of the lens 14, projecting onto the rear diopter 16 in an area which, in the signaling orientation, extends in the vicinity of the edge 25 of the reflector 22. As can be seen even better on the detail locket of FIG. 12, the prism 48 is provided with a diopter 49 which, in the signaling position, extends substantially parallel to the edge 25 of the reflector 22 to allow efficient transmission of the luminous flux of the lens 14 to the reflector 22. In FIG. 12, the path of the luminous flux is materialized by the broken line in broken lines, which accounts for the successive reflections undergone by the light rays coming from the secondary light source 44, successively on the walls of the lens 14 and then on those of the reflector 22. [0054] FIGS. 13 to 16 also show arrangements for making the power supply [0055] To this end, the lighting device 3 comprises an electrical circuit 50 for supplying the secondary light source 44, subdivided into two strands. , namely: a first strand 51 carried by the light block or the armature 6, and an end of which defines a first terminal 52 connected to a power supply (not shown in the drawings), and a second strand 53 carried by the 12 and an end of which defines a second terminal 54 connected to the source 44 secondary light. The arrangement of the electrical circuit 50 is such that in the signaling configuration of the mobile equipment 5, the secondary light source 44 is supplied with current, which makes it possible to illuminate the wafer 17 of the lens 14 and, when it is provided with a prism 48, the portion 25 of the reflector 22, while in road configuration the secondary light source 44 is deprived of power. More specifically, the strands 51, 53 of the electrical circuit 50 are organized so that the second terminal 54 is: spaced from the first terminal 52 in the road configuration (which opens the electrical circuit 50 and cuts the power supply secondary light source 44), in contact with the first terminal 52 in the signaling configuration (which closes the electrical circuit 50 and supplies the secondary light source 44). According to a first embodiment, illustrated in Figures 13 and 14, the first strand 51 is carried by the reflector 22. Each of the side walls 28 carries a first terminal 52 (in this case in the form of a pellet ) connected to the power supply by a first conductor 55 (only part of which is shown in the drawings), and the optic 12 carries a pair of second terminals 54, each mounted on a branch 18, in the form of a surrounding wafer. the second horizontal axis A2 of rotation and connected to the secondary light source 44 by a second conductor 56 which runs along the branch 18. As can be seen in FIG. 14, each first terminal 52 is placed on a lateral wall 28 of the reflector 22 in a position such that in the signaling configuration each second terminal 54 corresponding overlaps the corresponding first terminal 52. FIG. 13 shows that in road configuration, given the mobility of the lens 14 with respect to the light block, each second terminal 54 is spaced apart from each first terminal 52. According to a second embodiment illustrated in Figures 15 and 16, the first strand 51 (in honeycomb pattern in Figures 15, and 16) is carried by the stirrup 6. More specifically, each arm 9 carries a first terminal 52, in form an angular sector centered on the second axis A2 of rotation. Each branch 18 of the frame 13 carries a second terminal 54 of the second strand 53 (shaded in Figures 15 and 16) in the form of an angular sector also centered on the second axis A2 of rotation, so that, in the road configuration (i.e. in the optical path of the optics 12), the terminals 52, 54 are angularly spaced from each other, which opens the circuit 50 and cuts supplying the secondary light source 44 (FIG. 13), while in the signaling configuration (ie in the signaling orientation of the optics 12), the terminals 52, 54 are in contact by overlapping to close the electrical circuit 50 and thus supply the source 44 secondary light. This configuration of the electrical circuit 50 makes it possible to realize an automatic (although mechanical) rocker between the extinction of the secondary light source 44 in road configuration (to favor the ignition of the main light source 21) and its ignition in signaling configuration, so as to illuminate the slice 17 of the lens 14 and / or the diffusion zone 47 of the reflector 22. It can therefore be seen that the switching on and off of the secondary light source 44 are coupled, in a simple manner. and effective, the orientation of the optic 12. The lighting device 3 which has just been described can be mounted alone within a block 2 of the headlight. However, as shown in Figure 17, a same block 2 of the headlight can integrate several lighting devices 3 of this type, whose armatures 6 (or connecting rods 32) are for example coupled in rotation. This results in synchronization of the lighting devices 3, which jointly adopt their road or signaling configurations. The coupling can be achieved by a mechanical transmission, for example with gears (as illustrated), or with a chain or belt. A single motor 40 is sufficient to drive the whole. In the example shown, the motorization 40 is coupled to a drive wheel 57 by means of a belt 58. Similarly, in the example of FIG. 17, the main shafts 7 of the various devices 3 d 'lighting are parallel. Such parallelism is however not mandatory, and the main shafts 7 could be inclined relative to each other, for example to allow, in signaling position, to achieve a pattern by abutting the slices 17 of the different lenses along a predetermined line.5
