In a manner also known, a rigid air flow duct is placed between the air flow generator and the housing ice. This duct brings hot air having passed through the fins of the heat sink to an area of the ice, called cold zone, likely to give rise to visible condensation phenomena when a light source is turned on. A disadvantage of this state of the art is that it is necessary to provide a dedicated air flow duct for the flow of air between the air flow generator and the housing ice. This results in the use of one or more additional parts in the package resulting in higher manufacturing costs as well as greater bulk. In this context, the present invention aims to solve the aforementioned drawbacks.

DESCRIPTION OF EMBODIMENTS OF THE INVENTION Identical elements, structure or function, appearing in different figures retain, unless otherwise specified, the same references. The lighting and / or signaling device 10 for a motor vehicle according to the invention is described with reference to FIGS. 1 to 6. By motor vehicle, we mean any type of motorized vehicle. In a nonlimiting example taken in the following description, the lighting and / or signaling device 10 is a front projector of a motor vehicle. As illustrated in the sectional view of FIG. 1 and in the perspective view of FIG. 4, the lighting and / or signaling device 10 comprises: a housing 1; an ice cream 3 adapted to close the housing 1; at least one light module 5 housed inside said housing 1; a heat sink 11 comprising a plurality of fins 13; - An air flow generator 15 adapted to generate a flow of air 17 to the heat sink 11, all or part of the air flow 17 through the fins 13 of the heat sink 11; a support plate 19 having a front portion 20 comprising a plurality of interstices 21 adapted to direct the flow of air 17 from the heat sink 11 to the ice 3. In a non-limiting embodiment, the lighting and / or signaling device 10 further comprises a complementary structural element 23, called an exoskeleton. Said exoskeleton is attached and fixed in the housing 1. The various elements of the lighting and / or signaling device are described in detail below. The housing 1 is adapted to receive the light module or modules 5, the heat sink 11, the air flow generator 15 and the support plate 19. It thus delimits an interior volume to receive all these elements. The ice-cream 3 is adapted to close the casing 1. In a non-limiting embodiment, it comprises a transparent zone 30 and a black zone 32. The transparent zone 30 is a so-called cold zone at which there are risks of condensation or icing on its inner surface. The black zone 32 is a stylistic element and makes it possible to hide the inside of the lighting and / or signaling device 10. Of course, in another non-limiting embodiment, the ice cream 3 may be completely transparent, without a zone black. In a non-limiting embodiment, a light module 5 comprises at least one optical surface and at least one light source cooperating with said optical surface to form a light beam. As illustrated in Figure 1 in a non-limiting example, the light module 5 comprises: - a first light source 7 and a second light source 7 '. The first light source 7 is, for example, a light source providing a photometric function called "high beam" to achieve a high beam. The second light source 7 'ensures, for its part, a photometric function called "low beam" to achieve, for example, a dipped beam. a first optical surface 9 and a second optical surface 9 'cooperating respectively with the first light source 7 and the second light source 7'. The first optical surface 9 is here a reflector adapted to reflect a light beam from the first light source 7. The second optical surface 9 'is here a reflector adapted to reflect a light beam from the second light source 7'. The set of reflected light rays form a global light beam. - A third optical surface 9 "which is here a lens adapted to channel and orient the overall light beam. In a non-limiting embodiment, the light sources 7, 7 'are semiconductor emitter chips. In a non-limiting embodiment, each semiconductor emitter chip is part of a light-emitting diode. Light-emitting diode means any type of light-emitting diode, whether in non-limiting examples of LEDs ("Light Emitting Diode"), OLEDs ("organic LEDs"), AMOLEDs (Active-Matrix-Organic LEDs), or FOLED (Flexible OLED). The first light source 7 and the second light source 7 'cooperate with a folder 8. The latter deviates the overall light beam and thus directs it to the lens 9 ". FIG. 1 represents a sectional view of the lighting and / or signaling device 10. As already described, the lighting and / or signaling device 10 comprises the generator of a suitable airflow. to generate the air flow 17. By "air flow generator" is meant a fan adapted to stir a certain volume of air towards the heat sink 11. The fan 15 is fixed on the exoskeleton 23 . The heat sink 11 is adapted to evacuate the heat generated during operation by the light module 5. As illustrated in FIG. 2, the heat sink 11 comprises a plurality of fins 13 through which the air flow 17 flows from the air flow generator 15. In a nonlimiting embodiment, the fins 13 of the heat sink 11 are parallel to each other and spaced apart by a first distance DI. Thus, the air flow 17 is divided into a plurality of secondary flows by the fins 13 of the heat sink 11. Each secondary flow is heated by said fins 13. In a non-limiting embodiment, the fins 13 are arranged in a first plane P1. The heat sink 11 then directs the air flow 17 to the support plate 19. The support plate 19 is adapted to direct the flow of air 17 to the ice 3. It also has an aesthetic function. In a first non-limiting embodiment, the support plate 19 is fixed relative to the housing 1. In a second non-limiting embodiment, the support plate 19 is movable relative to the housing 1 so as to pivot according to a turn or to tilt according to the attitude of the motor vehicle carrying the lighting device. and / or signaling. For this, the lighting and / or signaling device 10 comprises one or more motors and a rod system (not shown). The motor or motors are slaved to the angle of rotation of the steering wheel of the vehicle so as to rotate the lighting device and / or signaling according to a turn. In the same way, the engine (s) can be slaved to the attitude of the vehicle. In non-limiting embodiments, the material forming the support plate 19 is: - pbt (polybutylene terephthalate); or glass filled polyamide (known as gf30); or - a rigid moldable plastic; or - aluminum; or - steel. As illustrated in Figure 1, the support plate 19 has a front portion 20a and a rear portion 20b. The front portion 20a comprises a plurality of interstices 21 adapted to direct the flow of air 17 to an ice 3. The rear portion 20b forms with an inner wall of the lighting and / or signaling device 10 a conduit for guiding air flow 17 to the interstices 21 of the front portion 20a. In the embodiment of FIG. 1, the inner wall belongs to the structural complementary element 23, here the exoskeleton. In another non-limiting embodiment, the inner wall belongs to the housing 1. The duct formed by the inner wall (1 or 23) and the rear part 20b of the support plate 19 has a spacing E1 (shown in FIG. 1) sufficient to guide the flow of air 17 towards the front part 20a of the plate. support 19. In a non-limiting example, the spacing E1 is between 20mm (millimeters) and 30mm. This spacing E1 has a section S1 which decreases towards the front portion 20a of the support plate 19, which accelerates the flow of air 17 towards this front portion 19a. In addition, as can be seen in FIG. 1, the support plate 19 and the inner wall direct the flow of air 17 towards the interstices 21 of the front portion 20a of the support plate 19. The interstices 21 are here arranged in a second plane P2. In a non-limiting embodiment, the second plane P2 of the interstices 21 is parallel to the first plane PI of the fins 13. This reduces the turbulence in the air flow 17. In another nonlimiting embodiment (not shown), the second plane P2 of the interstices 21 is coplanar with the first plane PI of the fins 13. The fins 13 are thus aligned with the interstices 21. This makes it possible to avoid the loss of speed of the air flow 17. FIG. 5 represents a perspective view of the front part 20a of the support plate 19. This front part 20a comprises a grid 28. This grid 28 has on a lower part a plurality of interstices 21. The interstices 21 of the support plate 19 are spaced apart by a second distance D2. In a non-limiting embodiment, the first distance DI between two adjacent fins 13 of the heat sink 11 is identical to the second distance D2 between two interstices of the grid 28. In this way, each secondary flow formed by the heat sink 11 will be able to pass in a gap 21 of the support plate. There is thus for each secondary flow a pair of adjacent fins pair / interstice associated. This promotes the circulation of secondary flows and therefore limits the pressure losses of the stream 17. There is less turbulence created and better heat exchange. In a non-limiting embodiment, the number of interstices 21 of the support plate 19 is greater than the number of fins 13 of the heat sink 11. This produces a style effect visible by an observer outside the motor vehicle. In a non-limiting embodiment, the support plate 19 comprises openings 22 for the passage of fixing screws for fixing the support plate 19 to the rest of the lighting and / or signaling device 1. Figure 6 shows a sectional view of a gap 21 of the front portion 20a of the support plate 19 according to a non-limiting embodiment. This gap 21 is formed by an inlet 210 (through which the airflow 17 enters), an outlet 211 (through which the airflow 17 exits) and two walls 212, 213 connecting the inlet 210 and the outlet 211 The inlet 210 has a section S2 and the outlet 211 has a section S3. In a non-limiting embodiment, the section S3 of the outlet 211 is greater than the section S2 of the inlet 210. In this way, it comes to create a venturi effect at the gap 21. This venturi effect makes it possible to increase the speed of flow of the air flow 17 towards the ice 3. By this increase in speed, it improves the defrosting and / or the removal of the condensation of the ice 3. This reduces the time to remove condensation and / or defrosting time. In a non-limiting embodiment, the walls 212, 213 are flat so as to promote the flow of the air flow and to limit the pressure drops. As can be seen in FIG. 6, the walls 212, 213 of the gap 21 form an angle α with a direction X, corresponding to the direction of travel of the vehicle. In a first nonlimiting embodiment, the angle a is constant and the walls 212, 213 of the gap are fixed. In a second nonlimiting embodiment, the angle a varies and the walls 212, 213 of the interstice 21 are movable. To make these walls 212, 213 mobile, the lighting and / or signaling device 10 comprises a motor (not shown) and a connecting rod system (not shown) connected to the walls of the gap 21. In this way, it It is possible to direct the stream 17 on specific areas of the ice. This improves the defrosting and / or the time to remove the condensation of these determined areas of ice 3. To improve the defrost and / or the time to remove the condensation of the ice 3, in a non-limiting embodiment, the lighting and / or signaling device 10 further comprises a complementary source of heat (not shown). In this way, it is possible to defrost and / or remove the condensation present on the ice 3 cold, namely: - without operating the light sources 7, 7 'of the light module 5, for example at the start of the vehicle; - When the light sources 7, 7 'of the light module 5 have just been turned on, the time that the heat sink 11 remove the calories from the light module 5 in operation. In a non-limiting embodiment, the complementary heat source is a heating resistor. In a non-limiting embodiment, the complementary heat source is disposed in the air flow 17 on the inner wall on which the flow of air 17 is passed, upstream or downstream of the interstices 21. In examples non-limiting, the complementary heat source is fixed on the exoskeleton 23 or on the housing 1. In a non-limiting embodiment, the lighting and / or signaling device 10 further comprises at least one mask which has an aesthetic function. As illustrated in FIG. 1, the lighting and / or signaling device 10 comprises a mask 27 disposed along a light guide support 33 (described below) and a mask 29 placed between the support plate 19 and the ice 3. The mask 29 defines with the optical surface 9 ', a spacing E4 having a section S4 sufficient for the passage of the air flow. It thus makes it possible to guide the flow of air 17 coming from the support plate 19 towards the upper part of the window 3. In a nonlimiting example, the spacing E4 is between 10 mm and 15 mm. In a non-limiting embodiment, the mask 29 is disposed relative to the ice 3 so as to prevent the passage of a portion of the air flow 17 between the mask 29 and the ice 3. This ensures that the entire air flow 17 from the support plate 19 is guided to the zones 30, 32 of the ice 3 to defrost and / or to remove the condensation. In a non-limiting embodiment, as illustrated in FIG. 1, the lighting and / or signaling device 10 further comprises a light guide 31 and a light guide support 33. The guide support light 33 is disposed relative to an upper portion 35 of the ice 3 so as to have a spacing E5 having a section S5. This spacing E5 is sufficient to allow the air flow 17 to pass along the upper part 35 of the ice 3. This ensures the evacuation of the air stream 17 from the lighting and / or signaling device 10 , once the defrosting operation and / or removal of the condensation carried out. In a non-limiting example, the spacing E5 is at least equal to 5 mm. Of course, the description of the invention is not limited to the embodiments described above. Thus, in a non-limiting embodiment, the lighting and / or signaling device 10 may be bi-modules, that is to say it may comprise two light modules 5 and two associated support plates 19 respectively. to the two light modules 5 and two fans 15 respectively associated with the two light modules 5. The two support plates 19 cooperate with each of the fans 15 and light modules 5 as described above and thus comprise interstices 21 as described above to direct the air flow 17 to the ice 3. Note that for reasons of cost optimization, it can be provided that only one of the two support plates 19 has interstices 21 as described above to direct the air flow 17 to the ice 3. The other plate has a front portion 20a full, without gaps 21. In this case, the support plate 19 with the interstices 21 cooperated more particularly surely with the light module 5, the light sources 7, 7 'release the more calories in operation. In a first non-limiting embodiment of this embodiment, a light module 5 is adapted to perform the so-called "high beam" photometric function and the other light module is adapted to perform the so-called "low beam" photometric function. In a second non-limiting embodiment of this embodiment, each light module 5 is adapted to perform part of the photometric function called "high beam" and a part of the photometric function called "low beam". Thus, each light module 5 comprises light sources 7 and 7 '(previously described). This makes it possible to optimize the power of the light sources 7 and 7 'because the power of the light sources associated with a photometric function is distributed over two light modules 5. It will be noted that the light beam produced to perform the so-called "low beam" photometric function is at break. It thus comprises two segments, one of which is horizontal and the other inclined. Thus, in this second variant, one of the light modules 5 comprises the light sources 7 'for producing the inclined segment, namely to produce a sub-function called "kink" in English, and the other light module 5 comprises the light sources 7 'to achieve the horizontal segment, namely to achieve a sub-function called "fiat" in English. Thus, the invention described has the following advantages in particular: it is possible to effectively defrost and / or remove condensation from cold areas of the ice by using calories from a light module belonging to the lighting device and / or signaling. The optical performance of the lighting and / or signaling device is thus no longer degraded by condensation or frost, and there is no longer any aesthetic problem because there are no longer drops of condensation on the internal surface of the ice 3; - The air flow is directed through a support plate which is a pre-existing part in the housing. It is thus not necessary to use additional specific duct to ensure the flow of air, which optimizes the manufacturing costs of the lighting and / or signaling device; - To improve the defrosting and / or the removal of the condensation of ice, the air flow is accelerated simply in the support plate by interstices that have specific shapes and inclinations; the spacings between the different elements of the lighting and / or signaling device are optimized so as to limit the pressure drops of the air flow; it is not necessary to install an additional piece as in the prior art; - The support plate is opened through the interstices, which improves the flow of air to the cold zone of the ice, unlike a support plate with a front part 20a full.
