    DEVICE FOR LIGHTING AND / OR LUMINOUS SIGNALING OF A VEHICLE
    AUTOMOBILE
    [001] The invention relates to lighting and / or signaling devices, intended more particularly for motor vehicles. The invention relates more specifically to a lighting device and / or light signaling comprising means for channeling an air flow arriving on said device.
    [002] In known manner, lighting and / or light signaling devices are arranged at the front and rear of a motor vehicle to, on the one hand, to illuminate the road to improve visibility the driver of the vehicle, especially in night conditions, and, secondly, to signal the position of the vehicle to other road users. In practice, a lighting and / or front light signaling device mainly includes the position lights, dipped beam and high beam whose different light intensities allow to adapt the lighting to outdoor conditions. To do this, a front lighting and / or light-signaling device comprises a plurality of light sources that can be actuated in order to activate the different lamps.
    [003] In a conventional manner, the different light sources are in the form of a plurality of halogen incandescent bulbs or light-emitting diodes, also designated as LEDs or LEDs for Light-Emitting Diode in English, mounted inside a housing whose front face is sealed by a wall made from a transparent resin and resistant to shocks to allow the light emitted by the light sources to be oriented towards the front of the vehicle . Such a front face, also referred to as "ice", serves to protect light sources from external conditions, including rain or any object projected towards the front of the vehicle and may damage said light sources . In addition, the front makes the aerodynamic housing guiding the air which limits the noise, also called "aerodynamic noise", generated by the flow of air hitting the front of the vehicle during its movement, especially at high speed.
    [004] Document FR3015003 discloses a lighting and / or light-signaling device that does not comprise a transparent front face or "ice". Such a lighting and / or light-signaling device comprises a plurality of lighting and / or light-signaling modules whose projection lens also serves as ice-cream.
    [005] For convenience, the terms "lighting modules" or "module" alone will be used later to designate modules that may as well contain light sources capable of producing traffic lights and / or lights lighting.
    [006] The modules are disposed inside a housing open towards the front of the vehicle, housing which is framed by a portion of the engine hood, a portion of the wing and a portion of the bumper. The lighting modules are movably mounted inside the housing to allow site adjustment relative to the housing which is fixed, which imposes gaps between the modules and the housing. Also, an object coming from the front of the vehicle can get stuck inside these spaces and damage the lighting device and / or light signaling. In addition, such lighting modules are not aerodynamic and generate noise when the vehicle is moving, especially at high speed.
    [007] The invention therefore aims to solve these disadvantages by providing a lighting device and / or aerodynamic light signaling and optimizing the evacuation of objects carried by the penetrating air flow inside the housing in which are arranged the modules.
    [008] To achieve this result, the present invention relates to a lighting device and / or light signaling of a motor vehicle, said device comprising: - a housing comprising a front opening adapted to allow the passage of air arriving from the front of the vehicle, a plate mounted inside said housing, at least one lighting and / or light signaling module fixed to a first face of said plate, said plate comprising adapted channeling means for guiding a flow of air entering through said opening towards the rear of the housing, said channeling means extending between the plate and the housing from a second face of the plate, opposite said first face.
    With the device according to the invention, it is possible to evacuate an object arriving on the front of the lighting device and / or light signaling towards the rear of said device through the air flow guided by the channeling means. Such an object is thus evacuated at the rear of the lighting device and / or light signaling so as not to remain blocked and thus accumulate in the device. In addition, the air channeling means limit air turbulence to limit aerodynamic noise when the motor vehicle is moving forward.
    Advantageously, the second face of the plate comprises a slope inclined downwardly of the housing.
    Advantageously, the channeling means comprise a protective wall extending laterally to the front of the plate.
    Advantageously, the protective wall comprises orifices adapted to allow the passage of air flow between the plate and the housing.
    Advantageously, the channeling means comprise at least one guide rib of the air flow extending longitudinally.
    Advantageously, the guide rib is derived from material of the second face of the plate.
    Advantageously, the channeling means are configured to limit aerodynamic noise by guiding the air flow.
    Advantageously, said at least one lighting module and / or light signaling comprises fixing means to the plate.
    Advantageously, the fastening means comprise at least one threaded hole, preferably three threaded holes.
    Advantageously, the plate comprises mounting means in the housing.
    Advantageously, the plate is adapted to allow adjustment of the site of the lighting module and / or light signaling.
    The invention also relates to a motor vehicle comprising at least one lighting and / or light signaling device as briefly described above.
    Other features and advantages of the invention will appear on reading the detailed description of the embodiments of the invention, given by way of example only, and with reference to the drawings which show: FIG. 1 a diagram of an embodiment of a lighting and / or light signaling device according to the invention mounted at the front of a car, • Figure 2, a side diagram of the lighting device and / or light signaling of Figure 1, and • Figure 3, an exploded view diagram of the lighting device and / or light signaling of Figure 1.
    In what follows, the described embodiments focus more particularly on an implementation of the device according to the invention within a motor vehicle. However, any implementation in a different context, in particular in any type of vehicle, is also covered by the present invention.
    FIG. 1 represents a lighting and / or light-signaling device 10 according to the invention, and more particularly, in this case, a front lighting and / or light-signaling device mounted at the front. of a motor vehicle 100. Such a lighting and / or light-signaling device 10 is framed by the bonnet 101, the wing 102, the bumper 103 and a trim 104 of the vehicle 100.
    In the following description, the terms "before", "back", "above", "below" and "vertical" are defined relative to the vehicle 100 flowing back and forth.
    Such a lighting device and / or light signaling 10 comprises a housing 1 in which are mounted a mounting plate 2 and two lighting modules 3, 4 and / or light signaling fixed to said plate 2 [ 0026] As illustrated in Figures 1 and 2, the housing 1 comprises a front opening 11. In other words, the housing 1 does not include a protective front wall, also referred to as "ice". Thus, a flow of air and / or objects coming from the front of the vehicle 100 can enter inside the casing 1. As illustrated in FIG. 2, the casing 1 also comprises two discharge orifices 12, 13 located at the rear and the front of the housing 1 to allow the evacuation of the flow of air and objects entering through the front opening 11. Finally, gutters 14 can guide the flow of air and the objects in the lower part of the housing 1 in order to evacuate them through the discharge openings 12, 13.
    As illustrated in FIG. 3, each lighting and / or light-signaling module 3, 4 comprises a sealed body 31, 41 in which a light source (not shown) is mounted, in particular light-emitting diodes, also LED or LED for Light-Emitting Diode in English language. It goes without saying that the lighting modules and / or light signaling 3, 4 could, alternatively, include at least one incandescent bulb or any other type of suitable light source. A light source is controlled, automatically or manually, to emit light towards the front of the vehicle 100 to illuminate the road ahead of the vehicle 100 and / or signal the position of said vehicle 100 to other users of the road. The light source is supplied with electricity by the vehicle 100. A projection lens 32, 42 is placed in front of the light source to guide the light emitted by said light source. Advantageously, the projection lens 32, 42 also makes it possible to protect the light source. Such a projection lens 32, 42 is made of a transparent and strong material, such as resin to allow the light emitted by the light source to pass through the projection lens 32, 42 so as to illuminate the road to the front of the vehicle 100 while protecting the light source from objects coming from the front of the vehicle 100.
    The sealed body 31, 41 further comprises means for fixing the lighting module and / or light signaling 3, 4 to the plate 1. Such fastening means comprise, in this example, tapped holes 33 , 43, and in particular three tapped holes 33, 43. Such threaded holes 33, 43 may be arranged in different ways, including two threaded holes 33 at the front of the sealed body 31 and a threaded hole 33 at the rear of the sealed body 31 or a threaded hole 43 at the front of the sealed body 41 and two tapped holes 43 at the rear of the sealed body 41.
    Finally, the sealed body 31, 41 comprises a heat sink 34, 44 of the heat generated by the light source of the lighting module and / or light signaling 3, 4. The heat sink 34, 44 is realized in a thermally conductive material, for example aluminum, to allow to cool the light source. The heat sink 34, 44 is mounted outside the sealed body 31, 41, preferably at a rear portion, to optimize its cooling. Thus, the heat generated by the light source is released from the module 3, 4 via the heat sink 34, 44.
    It has been presented a lighting device and / or light signal 10 comprising two lighting modules and / or light signaling 3, 4, but it goes without saying that it could include a different number, especially one or more than two.
    The plate 2 is the interface between the housing 1 and the lighting modules and / or light signaling 3, 4. In other words, the plate 2 to mount the lighting modules and / or light signaling 3, 4 in the housing 1.
    In addition, the plate 2 allows the setting of the site of the lighting modules and / or light signaling 3, 4. Such adjustment requires a set of adjustment between the plate 2 and the housing 1. The purpose of the The invention is thus to avoid the accumulation of objects between the plate 2 and the housing 1 which could prevent the setting of the site.
    The plate 2 comprises a body 21, mounting means in the housing 1 and means for fixing the lighting modules and / or light signaling 2, 3.
    The body 21 is made of a resistant material and defines two mounting areas, each being adapted to cooperate with a lighting module and / or light signaling 3, 4 in order to fix it.
    The mounting means comprise shapes 22, in "U", adapted to cooperate with the housing 1 and allow the mounting of the plate 2 in the housing 1, by a system of clips for example.
    The fixing means comprise in this example with reference to Figure 3, orifices 23 adapted to cooperate with the threaded holes 33, 43 of the lighting modules and / or light signaling 3, 4 in order to fix the modules. lighting and / or light signaling 3, 4 to the plate, by screwing for example.
    The plate 2 further comprises channeling means adapted to guide the flow of air arriving from the front of the lighting device and / or light signaling 10 and entering through the opening 11 of the housing 1. As illustrated in Figure 3, the plate 2 comprises a first face 2A on which are fixed the lighting modules and / or light signaling 3, 4 and a second face 2B, opposite to the first face 2A.
    Advantageously, the channeling means extend from the second face 2B in order to channel the flow of air flowing between the plate 2 and the housing 1.
    The channeling means comprise a protective wall 24 located at the front of the plate 2 and extending laterally. The protective wall 24 is advantageously made from the material of the plate 2. The protective wall 24 is adapted to block any object coming from the front of the vehicle 100 to prevent such an object from passing between the plate 2 and the housing 1, which can damage the lighting device and / or light signaling 10. Advantageously, the protective wall 24 is bent forward to guide the flow of air coming from the front and thus improve the aerodynamics of the protective wall 24. Such a curved protective wall 24 thus forms a deflector.
    The channeling means further comprise orifices 25 for air passage and ribs 26 for guiding the air. The orifices 25 pass through the protective wall 24, thus forming a perforated protection wall 24, so that the air arriving at the front of the protective wall 24 passes behind the protective wall 24 through the orifices 25. The number, size and position of the orifices 25 are adapted to allow the passage of air while avoiding the passage of an object too large size to prevent such an object is blocked in the device lighting and / or light signaling 10.
    The guide ribs 26 are made of material of the plate 2 and extend from the second face 2B. In addition, the guide ribs 26 are substantially parallel to the longitudinal axis of the vehicle 100 to guide the flow of air between the second face 2B of the plate 2 and the housing 1 from front to back. Thus, the flow of air coming from the front is guided and channeled by the orifices 25 and the guide ribs 26, which makes it possible to avoid a turbulent flow of the air and thus reduces the aerodynamic noises generated by the air.
    According to one aspect of the invention and with reference to Figure 2, the second face 2B comprises a slope inclined downwards to guide an object between the plate 2 and the housing 1 to the discharge port 12 of the housing 1, thanks to the force of gravity. The inclined slope thus avoids the formation of a bowl between the plate 2 and the housing 1 in which objects could accumulate.
    Thus, the ducting of the air and the inclined slope promote the flow of an air flow for guiding an object, including a pebble or water, arriving from the front of the vehicle 100 to the back of the housing 1 to prevent such an object is found blocked between the plate 2 and the housing 1. The air flow and channeled also allows to evacuate dust or other objects that can accumulate between the plate 2 and the housing 1. Advantageously, at the rear of the housing 1, the air flow is directed downwards to evacuate the object under the effect of gravity. Thus, the accumulation of object between the plate 2 and the housing 1 can prevent the setting of the site of the lighting modules and / or light signaling 3, 4 is prevented. In addition, such a ducting of the air makes it possible to limit aerodynamic noise.
    Advantageously, each lighting module and / or light signaling 3, 4 is fixed under the plate 2, and, as shown in Figure 2, an air flow can also be generated under each lighting module. and / or light signaling 3, 4 in order to evacuate the objects under the modules 3, 4 and to reduce aerodynamic noise as has been presented for the flow of air between the plate 2 and the casing 1.
