    [0001] The invention relates to the field of lighting and / or signaling, in particular for motor vehicles. BACKGROUND OF THE INVENTION More particularly, the invention relates to a lighting and / or signaling module for a motor vehicle, and a projector comprising such a module. The document FR 2 817 212 describes a motor vehicle headlamp with a directional lighting function better known by the acronym DBL (Dynamic Bending Light). The projector includes an optical system whose lighting direction is rotated, an output shaft coupled to the optical system for driving, an engine, and a rotational transmission mechanism coupled to the engine so that it is rotated. transmits the rotation of the motor to the output shaft, wherein the motor, the output shaft and the rotation transmission mechanism are placed in a housing body, and a rotating shaft of the motor is supported by the housing body . A support shaft of an intermediate gear placed between the motor and the output shaft is directly supported by the housing body. The document EP 1 285 812 describes a headlamp comprising a moving assembly provided with a reflector and a light source, and a fixed assembly bordering at least partially on the movable assembly that can rotate relative to the fixed assembly, around a first vertical axis for azimuth adjustment, and about a horizontal transverse axis for on-site adjustment. Such an arrangement is intended to keep the running games constant between the fixed parts and the moving parts.
    [0002] EP 1 985 913 discloses a front projector of a motor vehicle whose optical module is mounted on a gantry and is rotatable about a vertical axis of rotation to provide a directional function (DBL). The optical module is designed to produce a light beam projected forward through an active surface of a diopter. This active surface is the minimum area needed to produce a regulatory lighting beam. A mask is also provided to modify the area of the active surface, which allows the projector to provide the night or day lighting functions in the case of an integral or partial opening of the mask. If the mask is designed with a logo or figure, a parking sign feature is also provided. The projector of this teaching is thus limited to two lighting functions. EP 2 423 047 discloses a headlamp of a motor vehicle designed to combine the night lighting function with the daylighting function known by the acronym DRL (Daytime Running Light). The night lighting is obtained by a fixed lighting module, while the DRL lighting is achieved by means of a network of light-emitting diodes that can be retracted into a position inside the projector. The invention aims to provide a module and a lighting projector and / or signaling capable of providing at least two lighting and / or signaling functions and simple and compact construction.
    [0003] For this purpose, the invention relates to a lighting and / or signaling module for a motor vehicle, comprising at least one light source and at least one reflector. According to the invention the reflector is movable under the effect of an actuator, and the light source is fixed relative to the actuator. Furthermore, the invention has the following characteristics, considered alone or in combination: the reflector is rotatable about an axis, the axis is substantially vertical, the reflector and the light source co-operate to fulfill a function lighting and / or regulatory signaling, 25 - the light source is substantially aligned with the axis, - the reflector is formed on one side of a support integral with the axis, - the support comprises at least a second face performing a second function, - the second function is a lighting function and / or regulatory signaling, - the second function is an aspect function, - the module comprises at least a second light source, - the second light source cooperates with at least one light guide, - the second light source cooperates with at least one face of the support, - the second light source is fixed relative to the first light source. se, - the sheet guide is secured to the support, - the light guide is constituted by a sheet guide whose peripheral portion returns the light of the second source to fulfill a signal function, - the sheet guide is fixed by relative to the light source, - the light guide consists of a sheet guide whose peripheral portion returns the light of the second light source to fulfill a signal function, - the light source is constituted by a light emitting diode (LED) the second light source consists of a light-emitting diode (LED).
    [0004] The invention also relates to a lighting and / or signaling projector for a motor vehicle, comprising a housing and at least one lighting and / or signaling module having the characteristics listed above. Other features and advantages of the present invention will become more apparent from the description and the drawings, of which: FIG. 1 is an isometric perspective illustration of a preferred embodiment of a lighting module and or signaling according to the present invention, the device being in a first configuration; FIG. 2 is an isometric perspective illustration of the lighting and signaling module of FIG. 1, the device being in a second configuration; FIG. 3 is a side view of the lighting and / or signaling module of FIG. 1; FIG. 4 is a side view of the lighting and / or signaling module of FIG. 2; Figure 5 is an isometric perspective illustration of an alternative embodiment of a lighting module and / or signaling according to the invention, the device being in a first configuration; Figure 6 is an isometric perspective illustration of the lighting and signaling module of Figure 5, the device being in a second configuration. Figures 1 to 4 illustrate the principle of the invention and correspond to a preferred embodiment. They schematically illustrate a lighting module and / or signaling 10, fixed in a housing (not shown) of a projector, comprising an actuator 12 integral with the housing, an axis 14 rotated by the actuator 12 and The actuator 12 comprises an electric motor and means for transmitting rotation between the motor and the axis 14. The axis 14 preferably supports the support 16 at its lower part. In the embodiment shown, the axis 14 is substantially vertical, but it could have another orientation. By "substantially" is meant that the axis 14 can form an angle with the vertical of at most 20 °. The support 16 of the module 10 comprises a first reflecting surface 18 providing a lighting function and / or regulatory signaling. This function is fulfilled by the cooperation of the face 18 with a light source 26. The latter is fixed and positioned on a printed circuit 22, itself fixed in the housing (not shown) of the projector. The light source 26 is fixed relative to the actuator. "Regulatory" means that a lighting and / or signaling function complies with the regulations in force. This lighting function and / or regulatory signaling can be a day signaling function, commonly referred to as the DRL (the English acronym "Daytime Running Light"), a crossover function, commonly referred to as " code ", a function commonly referred to as a" road ". The face 18 thus ensures the formation of a lighting beam and / or regulatory signaling directed towards the front of the vehicle.
    [0005] The support 16 of the module 10 also comprises a second face 30 providing a second function. This second function can be either a regulation day signaling function, a crossover lighting function and / or regulatory route, or an aspect function. The support 16 of the module 10 optionally comprises more than two faces each providing a lighting function and / or regulatory signaling, or an aspect function. In the embodiment shown, the support 16 has a prismatic shape but it could have another shape. The module 10 further comprises a light guide 20 cooperating with a second light source 24 thus providing a regulatory signaling function. The light source 24 is fixed and positioned on the printed circuit 22. It is therefore fixed with respect to the first light source 26. It may consist of one or more light-emitting diodes (LEDs). The light guide 20 in the example has two faces 32 and 36, each having an edge 34 and 38 respectively. The light guide 20 is preferably a sheet light guide. In a preferred embodiment, the peripheral portion 34 or 38 of the face 32 or 36 plumb with the second light source 24 of the strip guide returns light from the second source 24 towards the front of the vehicle to fill a signaling function and / or backward to participate in the appearance function. The aspect function of the face 30 of the support 16 can thus be accompanied by the signaling function provided by the light guide 20. Preferably, as shown in FIGS. 1 to 4, the module 10 comprises an upper pivot 28 collinear with the axis 14 via the support 16 to increase the accuracy of the relative positioning of the light source 26 with respect to the reflector 18, as well as the accuracy of the relative positioning of the light source 24 with respect to the faces 32 and 36 of the light guide 20. In a preferred embodiment shown in Figures 1 and 3, the web guide has two faces 32 and 36 as the support has two faces 18 and 30, each of the faces of the light guide Cooperating successively with the light source 24.
    [0006] In Figures 1 and 3, the module 10 is oriented so that the reflector 18 is visible and oriented towards the front of the vehicle. The module 10 accordingly provides in this configuration the lighting function and / or regulatory signaling described above.
    [0007] In FIGS. 2 and 4, the support 16 of the module 10 has undergone with respect to the configuration of FIGS. 1 and 3 a rotation of 180 ° in the example represented, so as to present the second face 30 thus ensuring the function of aspect and / or lighting and / or signaling also described above. In the configuration shown in FIGS. 1 and 3, when the light source 26 is on, it emits light rays towards the reflector 18. The reflector 18 sends the light rays towards the front of the vehicle to fulfill the lighting function and / or regulatory signaling. In their path, the light rays pass through the transparent face 32 of the strip light guide 20. The lighting function can also be directional, that is to say of the DBL (Dynamic Bending Light) type, thanks to the actuator 12 of the module 10. In other words, the module 10 can not only ensure the change of lighting function and / or signaling but also provide the directional function of the lighting function of the module. The light source 26 is preferably of the electroluminescence diode (LED) type, and is substantially aligned with the axis 14. The expression "substantially aligned" means that the distance between the geometric center of the LED 26 and the The axis of rotation of the support 16 is not greater than the dimensions of the LED 26. The light source 24 can also be lit in addition to the light source 26 so that the peripheral portion 34 of the face 32 emits light. This makes it possible to use the light guide 20 in addition to the reflector 18. However, when the lighting and / or signaling function provided by the reflector 18 is not used, the module adopts automatically or on command the configuration shown in FIGS. 2 and 4. The aspect face 30 is then visible through the face of the guide 36. The light source 24 can also be lit so that the peripheral portion 38 of the face 30 emits light to fulfill a function signaling and / or appearance.
    [0008] The module 10 changes from the configuration illustrated in FIGS. 1 and 3 to the configuration illustrated in FIGS. 2 and 4 and vice versa by a rotational movement of the support 16 accompanied by the light guide 20. The movement is generated by the actuator 12 through the axis 14 and pivot 28.
    [0009] Figures 5 and 6 illustrate the principle of the invention and correspond to an alternative embodiment. They schematically illustrate a lighting and / or signaling module 100, fixed in a housing (not shown) of a projector, comprising an actuator 12 integral with the housing, an axis 14 driven in rotation by the actuator 12 and integral with a support 16. In this embodiment, the light guide 20 consists of a single face 32 cooperating with the light source 24. As a result, the light guide is fixed, for example by being integral with the The light guide is preferably a sheet light guide. In a preferred embodiment, the peripheral portion 34 of the web guide returns light 15 from the second light source 24 towards the front of the vehicle to perform a signaling function and / or backward to participate in the function of the light source. 'aspect. In Figure 5, the module 100 is oriented so that the reflector 18 is visible and oriented towards the front of the vehicle. The module 100 accordingly provides in this configuration the lighting function and / or regulatory signaling 20 described above. In FIG. 6, the support 16 of the module 100 has undergone with respect to the configuration of FIG. 6 a rotation of 180 ° in the example represented, so as to present the second face 30 of the support 16 thus ensuring the function of aspect and / or lighting and / or signaling also described above. In the configuration shown in FIG. 5, when the light source 26 is on, it emits light rays towards the reflector 18. The reflector returns the light rays towards the front of the vehicle to fulfill a lighting function and / or regulatory signaling. In their path, the light rays pass through the transparent face 32 of the sheet light guide 120. The lighting function can also be directional, ie of the DBL (Dynamic Bending Light) type, thanks to the Actuator 12 of the module 100. In other words, the module 100 can not only ensure the change of lighting function and / or signaling but also provide the directional function of the lighting function of the module. The light source 26 is preferably of the electroluminescence diode (LED) type, and is substantially aligned with the axis 14. The expression "substantially aligned" means that the distance between the geometric center of the LED 26 and the The axis of rotation of the support 16 is not greater than the dimensions of the LED 26. The light source 24 can also be turned on in addition to the light source 26 so that the peripheral portion 34 of the light guide 120 emits light. This makes it possible to use the light guide 120 in addition to the reflector 18. On the other hand, when the lighting and / or signaling function provided by the reflector 18 is not used, the module adopts the configuration represented automatically or on command. in Figure 6. The aspect face 30 is then visible through the face 32 of the light guide 120. The light source 24 can also be turned on so that the peripheral portion 34 of the face 30 emits light to fill a signaling and / or appearance function. The module 100 goes from the configuration illustrated in FIG. 5 to the configuration illustrated in FIG. 6 and vice versa by a rotational movement of the support 16. The movement is generated by the actuator 12 via the axis 14 and the pivot 28. As for the light guide 120, it remains fixed with respect to the printed circuit 22 during the rotation of the support 16. According to the two embodiments, the lighting function and / or signaling of the reflector and / or the signaling function and / or appearance of the light guide can also be used to create a vehicle ignition animation also called "welcome function", thanks to the rotational movement means 12 of the module 10 and / or the In other words, a luminous animation at the level of the projectors comprising one or more modules according to the variants of the invention will be effected in response to the unlocking command of the doors and / or the door. startup of the engine.
    [0010] Of course, the invention is not limited to the description of the embodiments above, but extends to the many variants that the skilled person can provide. Thus, for example, that: the guide does not comprise a central layer and is limited to a longitudinal guide at the edge of the reflector for example. In this case it can be provided two light sources, for example LED type, one at each end of the longitudinal guide. the regulatory signaling function of the light guide according to the invention can also be accompanied by an aspect function, namely with active lighting and / or with backlighting in the manner of a retro-reflector, the projector may comprise several modules identical to that which has been described, each module having its motor for rotating independently, - several modules or all the modules are actuated by the same engine thanks to a connecting rod system and / or several stages of gears, - the light guide of the invention has a glossy appearance on all or part of its surface for the aspect function, - the light guide of the invention has patterns and / or inscriptions on all or part of its surface for the aspect function, the beams generated by the module or modules which have been described above may constitute beams complementary to regulatory beams generated by the device. s conventional. the beams generated by the module or modules which have been described above may together constitute regulatory light and / or signaling beams.
