    Air extractor for motor vehicle headlamp
    The invention relates to an air extractor for a headlamp, in particular an air extractor for a motor vehicle headlamp. The invention also relates to a projector comprising an air extractor and a motor vehicle comprising such a projector. Finally, the invention relates to a method of using such an air extractor.
    To increase the efficiency of headlamps or light modules in headlamps, and in particular motor vehicle headlamps, components of the spatial light modulator type can be used to form selectively activatable segmented beams. Light source arrays are an example of components of the spatial light modulator type. However, these dies heat up a lot due to their number and the rise in temperature rapidly degrades their performance.
    Another example of components of the spatial light modulator type is also known components of the LCD screen type or micro-mirror arrays (also called DMD for the acronym for digital micromirror device).
    Thus, it would be interesting to integrate in a projector components of the spatial light modulator type such as MEMS (for "electromechanical microsystems"), arrays of micro-mirrors, LCD screens or lasers.
    However, the limit temperature for using such components is quite low (around 85 ° C), so it is impossible to use them under normal temperature conditions for projectors. Indeed, a projector is in the form of a closed assembly comprising heating elements and positioned near a motor, and the temperature inside the projector can reach high values, and the temperature limit for use of components is quickly exceeded.
    In addition, such components require a sealed environment, in particular to external particles. Indeed, the presence of external particles can greatly reduce the performance of electronic components in the projector. The projector must therefore be protected from the outside environment.
    To meet these constraints, there are projectors comprising heat exchangers coupled to fans positioned near the sensitive components to cool them directly.
    However, a first drawback of such projectors lies in the number of additional manufacturing steps and the addition of a large number of additional components to small areas during manufacturing.
    A second drawback is that the repair of such a system, in the event of a fan failure, is complicated to perform. It is thus preferable to replace the entire projector or the housing comprising the components of the spatial light modulator type, which involves additional costs.
    A general object of the invention is to provide a headlamp solution improving existing solutions, and allowing the use of heating components without the risk of exceeding their limit of use temperature.
    More specifically, a first object of the invention is to find a compromise making it possible to use components of the spatial light modulator type, within a projector by maintaining their temperature below their operating limit value while guaranteeing sealing. of the projector.
    A second object of the invention is to provide a solution for a projector which is simple to implement and inexpensive.

    In the following description, the following terms are defined and can be understood as follows:
    We define by the longitudinal direction the direction oriented from front to rear relative to a motor vehicle, the adjectives front and rear being defined relative to the usual movement of the vehicle. We define by transverse direction the direction perpendicular to the longitudinal direction and oriented from right to left of a motor vehicle. The two longitudinal and transverse directions define a horizontal plane. The vertical direction is perpendicular to the horizontal plane, oriented upwards. These same directions will be used for the description of a headlamp, by considering the headlamp as it would be positioned within a vehicle.
    The adjectives “upper” and “lower” will thus be used relative to the vertical direction defined above.
    The expression “external particles” designates an element present in the external environment of the projector and capable of reducing the performance of the components present in the projector by contact. The external particles can include, without limitation, dust, water, oil splashes, detergent splashes or sheets.
    The concept of the invention is based on the use of an air extractor, arranged at the level of a projector, making it possible to evacuate the hot air present in the projector to replace it with fresh air, to reduce the average air temperature inside a projector and therefore the temperature of the components positioned inside the projector. This principle is illustrated schematically in Figure 1, which shows a headlight 103 mounted on a motor vehicle 101 equipped with an air extractor 102 according to an embodiment of the invention. Advantageously, the fixing of such an air extractor 102 on the projector 103 is removable, to allow its replacement in the event of failure.
    The projector 103 comprises at least one optical module 105. This optical module comprises one or more components sensitive to temperature, comprising for example, at least one component of the spatial light modulator type, a semiconductor component, a MEMS, a matrix micro-mirrors, a liquid crystal display or a laser.
    Advantageously, this optical module comprises a proper cooling system for the electronic component (s): however, as the optical module is integrated in a projector comprising an air extractor according to an embodiment of the invention, which limits its average temperature , this clean cooling system can be simple and include only conduction and natural convection cooling. Thus, the optical module does not include a fan. It is thus simplified compared to the usual optical modules comprising the same electronic components. Naturally, the invention remains compatible with these traditional optical modules comprising their own cooling system with fan (s).
    By "natural convection" is meant a convection which is not forced, that is to say carried out without a fan or any other similar means making it possible to impose an air flow locally in contact with or near the optical module.
    The headlight 103 further comprises a lens 106, arranged flush or projecting with respect to the body 107 of the vehicle 101.
    The air extractor 102 is arranged on or through a wall of the projector 103. The air extractor can thus achieve fluid communication between the interior and the exterior of the projector 103. The air extractor 102 is arranged to allow the extraction of air inside the projector to the outside of the projector 103. In one embodiment, the projector comprises an air inlet 104 of the projector. The warm air inside the projector is replaced by cooler air and the overall temperature of the air inside the projector decreases.
    The air extractor 102 is preferably arranged on the upper part of the projector 103. In fact, the hot air being less dense than the cold air, the air inside the projector 103 is warmer in the part projector 103 than at the bottom. The arrangement of the air extractor 102 in the upper part of the projector 103 thus advantageously makes it possible to extract the hottest air towards the outside of the projector and thus promotes the descent in temperature of the air to the inside of projector 103.
    In one embodiment, the air extractor 102 includes an air guide whose inlet is arranged on the upper part of the projector 103. The air extractor 102 could then be arranged on a lower part or a intermediate part located between the lower part and the upper part of the projector 103, the air guide making it possible to bring the hot air situated in the upper part of the projector 103 to the extractor.
    In one embodiment, an air inlet 104 of the projector is arranged on the lower part of the projector 103. The air inlet of the projector 104 can be arranged on the lower surface 108 of the projector. Preferably, the air inlet of the projector 104 is located below a horizontal plane passing through the air extractor 102.
    In one embodiment, the air inlet of the projector 104 is arranged on the front part of the projector 104, that is to say the part closest to the lens 106 of the projector 103. Such an arrangement of the air inlet of the headlight 104 advantageously allows a cooler air inlet inside the headlight 103, in particular by moving the air inlet of the headlight 104 away from the engine of the vehicle 101, generally located at the rear of the headlight projector 103.
    In one embodiment, the air inlet of the projector 104 comprises an air guide, the inlet of which is arranged on the front part and / or on the lower part of the projector 103.
    The air inlet of the projector 104 may include an air filter. The air filter advantageously allows the passage of air from the outside to the inside of the projector 103 by preventing external particles from entering the interior of the projector 103 by the air inlet of the projector 104.
    An example of an air extractor 201 according to a first embodiment is described below with reference to FIGS. 2A, 2B and 2C.
    The air extractor 201 comprises an air inlet 203 and an air outlet 214, more particularly shown in FIG. 2C. The air extractor
    201 also comprises a ventilation chamber 210. Said ventilation chamber 210 is advantageously disposed between said air inlet 203 and said air outlet 214 of the air extractor 201. The ventilation chamber 210 comprises a fan 202. By fan is meant any means for generating an air flow between the air inlet 203 and the air outlet 214.
    The fan 202 can be a radial fan, an axial fan or any other type of fan. In one embodiment, the fan
    202 is designed to generate a flow of air at the outlet of air whose speed is substantially equal to 5 meters per second. In one embodiment, the fan 202 is designed to generate an air flow at the air outlet of between 100 and 500 L / min.
    As illustrated in FIG. 2B, the air extractor 201 is arranged in the rear and upper part of a projector 213, in a similar manner to the diagram in FIG. 1. The air inlet 203 is arranged to be positioned at inside the projector 213. The air outlet 214 is arranged to be outside the projector 213. The fan 202 thus makes it possible to draw the internal hot air inside the projector 213 through the inlet air 203 and expel it to the outside of the projector 213 and the air outlet 214 of the air extractor.
    The air extractor 201 also includes a sealing system, at least for external particles. In a nonlimiting embodiment, the sealing system is also airtight. The exterior particle sealing system prevents exterior particles present in the air outside the projector 213 from entering the interior of the projector 213 when the fan is off or when the fan is not activated. .
    In fact, when the air extractor 201 is operating, a through air flow is generated from the air inlet 203 to the air outlet 214 from the air extractor 201. This air flow through prevents outside particles from passing through the extractor to the inside of the projector. However, when the fan 202 is turned off, no air current is generated and it is therefore important for the preservation of the components present in the projector to close the extraction system so that no dust enters the projector by the air extractor.
    In one embodiment, the air extractor does not include an air filter, which avoids creating too great a resistance to the air flow.
    A first example of a sealing system is illustrated in FIG. 2A. In this first embodiment, the sealing system comprises a sealing means 206. The sealing means 206 may be located in the ventilation chamber 210, in the air inlet 203 or in the outlet of air 214. The shutter means 206 may be a hatch covering the entire section of the air extractor.
    The shutter means 206 is designed to be able to take or to be able to move between two positions: an open position (FIG. 2C) allowing fluid communication between the air inlet and the air outlet of the extractor air and a closed position (Figure 2B) to prevent at least the passage of external particles between the air outlet and the air inlet.
    In one embodiment, the shutter means 206 is movable between two limit positions: the closed position and the open position.
    In the closed position, the shutter means 206 can cover a section of the air extractor so as to prevent at least the external particles from passing through this section. Said section can be located in the ventilation chamber 210, in the inlet or outlet of the air extractor.
    The shutter means 206 may be a hatch made of gas-impermeable material or of material permeable to air and impermeable to external particles.
    The shutter means 206 can be movable between a closed position (Figure 2B) and an open position (Figure 2C) by a translational movement or by a shutter system (s).
    The air extractor 201 may also include an air guide 204. The air guide 204 makes it possible to fluidly connect the air inlet 203 of the air extractor with the ventilation chamber 210. The guide of air 204 thus makes it possible to provide an air extractor 201 comprising an air inlet 203 oriented towards the upper side of the extractor. This air guide 204 thus advantageously makes it possible to place the air inlet 203 towards the top of the projector. In this way, the air guide 204 allows the suction of the air from the projector in the highest possible position, therefore the warmest air 211, rather than the cooler air 212 present in the lower part of the projector 213. The air guide 204 comprises a longitudinal channel or pipe. In the embodiment, the air guide 204 makes it possible to form a tortuous path for the air, which also contributes to limiting the possibilities of passage of any external particles from the outside towards the inside of the projector, and therefore participates in the sealing function.
    The air extractor 201 may also include leaktight seals 208 to guarantee sealing between the extractor 201 and the projector 213 and / or between the walls of the extractor 201 and the closure means 206.
    FIG. 2D illustrates a variant of the first embodiment, in which the shutter means 206 is arranged at the entrance to the ventilation chamber 210. The two variant embodiments can also be combined.
    In this first embodiment, the projector further comprises a control device 209 for the air extractor 201, shown in FIGS. 2A and 2D. This control device may comprise an activator, arranged to control the opening and closing of the at least one closure means 206. The activator 209 may comprise a motor or an animated arm making it possible to move the closure means 206. The control device can also comprise a processor 207 and / or a printed circuit. The processor can be connected to the activator 209 by means of communication, in order to control the shutter means via the activator.
    The control device is configured to trigger the operation of the air extractor when the engine of the vehicle 101 is started, and to stop it when the engine is stopped.
    FIGS. 3A and 3B represent an air extractor 301 according to a second embodiment, respectively in the open and closed configuration.
    In this embodiment, the air extractor 301 comprises at least one shutter means 306 movable in rotation. In particular, the closure means 306 can be movable in rotation around a pivot 309, oriented in the transverse direction. This shutter means 306 is designed for, in the closed position represented by FIG. 3A, simultaneously closing the inlet and the outlet of the ventilation chamber 310. In the open position represented by FIG. 3B, it simultaneously opens the entry and exit of the ventilation chamber 310. As a variant, this closure means could open and close the air inlet 303 and the outlet 314 of the air extractor 301.
    The closure means 306 is of sufficient length on either side of the pivot 309 to, in the closed position, make it possible to cover the section of the inlet of the ventilation chamber 310 and the section of the outlet of the ventilation chamber 310.
    The ventilation chamber 310 may include leaktight seals 308 disposed between the pivot 309 and the wall of the projector 313. The extractor 301 may also include a leaktight seal 308 between the ventilation chamber and the walls of the projector.
    The sealing means 306 may comprise a surface 305 which is impermeable to external particles and permeable to gases.
    The air extractor 301 further comprises an air guide 304 designed so that the air inlet of the extractor 303 is oriented upwards or towards the upper face of the projector 313. Thus, the extractor 301 can suck in the hottest gases 311, rather than the cooler gases 312 located at the bottom of the projector.
    In a third embodiment illustrated by FIG. 4, an air extractor 401 likewise comprises an air inlet 403, then an air guide 404 towards a ventilation chamber 410 equipped with at least one fan 402. In this embodiment, the sealing system comprises an outlet channel 405 having at least one curvature. This outlet channel 405 having at least one curvature is arranged between the ventilation chamber 410 comprising the fan 402 and the air outlet 414 of the air extractor 404. As a variant, the outlet channel 405 may comprise several curvatures . Preferably, said outlet channel 405 comprises a curvature between 150 ° and 200 °, that is to say that it guides the air extracted by the air extractor 401 along a path comprising such a significant curvature, before it leaves the extractor. Such a curve, substantially around 180 °, allows the outlet channel 405 to orient the air outlet 414 towards the rear wall of the projector 413. Thus, the air outlet 414 is not oriented towards the motor of the vehicle. This orientation makes it impossible or very difficult, when the fan is off, for the entry of external particles inside the projector by the air extractor. The outlet channel 405 thus fulfills the sealing function. Alternatively, the sealing system could be implemented by any other channel having at least one curvature, not necessarily positioned at the outlet of the air extractor.
    In one embodiment, the outlet channel 405 further comprises a filter or a grid 415 near the air outlet 414. This grid makes it possible to brake or stop the external particles, which will tend to deposit on this grid. rather than traveling the route through the outlet channel 405.
    The grid 415 covers the section of the outlet channel 405. Preferably, the grid completely covers the section of the outlet channel 405 at the air outlet 414. Preferably, the grid comprises a succession of flaps or wires. The spacing between each adjacent flap or between each adjacent wire is between 0.5 and 3 mm
    Preferably, the outlet channel 405 further extends over a length sufficient to seal the external particles of the air extractor 401. The outlet channel 405 can extend over a length at least greater than 25 mm and / or less than 200mm.
    The diameter or the width of the section of the outlet channel 405 can be between 15 and 50 mm. The dimensions of the section of the outlet channel 405 contribute to the sealing of the air extractor 401, while allowing the passage of the air flow during the operation of the fan 402.
    The advantage of this solution is that it avoids the use of mechanical devices such as mobile shutter means, such as shutters. Advantageously, this solution can also do without an air filter.
    The outlet channel 405 can also be designed to, once mounted on the headlight 413 and on a vehicle, have a slope so that water which would be present in the outlet channel, for example following a projection or by condensation, either evacuated by gravity through the air outlet 414 of the extractor 401. The air outlet 414, when the air extractor is mounted on a headlight on a vehicle, is advantageously arranged at a height lower than the air outlet of ventilation chamber 410.
    In addition, in all the embodiments, the ventilation chamber is designed to have a slope with respect to a horizontal plane. This slope makes it possible, once the extractor is mounted on a headlight of a vehicle, to allow an outward flow of water on the walls of the ventilation chamber, without entering the headlight. As shown in FIGS. 2A to 4, the upper part of the ventilation chamber, arranged outside the projector, has a slope with a horizontal plane so as to evacuate the water. In these embodiments, water cannot stagnate in the air extractor or enter the interior of the projector.
    The invention is not limited to the embodiments described. For example, other embodiments can be obtained by removing the air guide from these embodiments, which remains optional. In addition, any other means of obturation can be envisaged. For example, a flap can be mobile according to a movement other than a translation or a rotation, or according to a translation in a direction other than that described in the first embodiment, or according to a rotation around an axis oriented according to a other direction than that described in the second embodiment.
    In addition, the at least one closure means may comprise at least two or a plurality of flaps. In this case, the different flaps are configured to perform a rotational movement in a synchronized manner. Each flap is arranged to, in the closed position, cover part of the section of the air extractor. The flaps are arranged so that when they are all in the closed position, they cover the entire section of the air extractor. For example, in one embodiment, the at least one closure means comprises a double flap.
    In addition, in all the embodiments, the air extractor comprises a control device, such as that described with reference to the first embodiment.
    This control device can moreover implement a method of extracting air from a headlamp, comprising in particular a method of activating the air extractor, automatically triggered when the motor vehicle is started, and automatically stopped when the motor vehicle engine stops. The projector and / or the air extractor thus comprises a mobile shutter means, and includes hardware and / or software elements for implementing the air extraction method.
    In an embodiment associated with an air extractor with a movable flap, as according to the first or the second embodiment of the invention, the method of activating the air extractor advantageously comprises the following steps:
    - fan activation; then
    - moving the at least one shutter to reach an open position.
    Preferably, the movement step is executed at least one second, preferably at least 3 or 4 seconds, very preferably between 3 and 6 seconds after the execution of the activation step. In this way, the activation of the fan causes the ventilation chamber to be pressurized before the shutter means open. This overpressure advantageously ensures that no dust can enter the interior of the projector through the extractor when it is put into operation.
    The fan activation step may be preceded by a step of receiving a control signal, for example a signal generated when the engine is started, is energized.
    Similarly, the process of deactivating the extractor comprises the following steps:
    - the displacement of the closure means in the closed position;
    - deactivation of the fan.
    Preferably, the deactivation step is executed at least one second, preferably at least 3 or 4 seconds, very preferably between 3 and 6 seconds after the execution of the displacement step. In this way, it can be guaranteed that no dust can enter the interior of the projector through the extractor when it is stopped.
    The displacement step may be preceded by a step of receiving a control signal, for example a signal generated when the engine is off, is de-energized.
