Description

P ROJ ECTE U R D E VE H I C U LE  P ROJECTE U R D E VE H I C U LE
La présente invention concerne de manière générale un projecteur de lumière monté sur un véhicule automobile, autrement appelé phare. The present invention generally relates to a light projector mounted on a motor vehicle, otherwise called a headlight.
Le document EP2325883 divulgue un type de projecteur connu, avec un boîtier contenant une ou plusieurs sources de lumière (de type diode électroluminescente (LED ou DEL), lampe halogène ou ampoule à filament classique), des lentilles et/ou des réflecteurs agencés pour diriger la lumière émise dans une direction particulière. Une face du boîtier est une glace transparente pour permettre de projeter la lumière vers l'extérieur du projecteur, tout en garantissant une bonne étanchéité au boîtier. Ainsi, si des éléments mobiles (réglage de l'azimut et/ou de la hauteur de projection par exemple) sont prévus dans le boîtier, ceux-ci seront protégés des contaminants extérieurs par la glace, tels que du sable, des gravillons ou de l'eau par exemple. EP2325883 discloses a known type of projector, with a housing containing one or more light sources (light emitting diode (LED or LED), halogen lamp or conventional filament bulb), lenses and / or reflectors arranged to direct the light emitted in a particular direction. One side of the housing is a clear glass to allow the projection of light towards the outside of the projector, while ensuring a good seal to the housing. Thus, if movable elements (azimuth and / or projection height adjustment for example) are provided in the housing, they will be protected from external contaminants by ice, such as sand, gravel or sand. water for example.
Cette glace transparente est généralement collée sur les parois du boîtier et présente plusieurs inconvénients : This transparent ice is generally glued on the walls of the housing and has several drawbacks:
- elle ne transmet qu'une partie de la lumière qu'elle reçoit (jusqu'à 10% de la lumière sont absorbés par une telle glace),  it transmits only a part of the light it receives (up to 10% of the light is absorbed by such ice),
- elle peut s'opacifier dans le temps (et absorber encore plus de lumière), - it can become opaque in time (and absorb even more light),
- elle augmente les coûts du projecteur, - it increases the costs of the projector,
- elle nécessite un procédé de collage complexe et coûteux, it requires a complex and expensive process of bonding,
- elle cache ou masque les éléments techniques du projecteur de l'extérieur, ce qui limite la signature extérieure du véhicule.  - It hides or masks the technical elements of the projector from the outside, which limits the external signature of the vehicle.
Un but de la présente invention est de répondre aux inconvénients des documents de l'art antérieur mentionnés ci-dessus et en particulier, tout d'abord, de proposer un projecteur de véhicule muni d'éléments mobiles mais dépourvu de glace extérieure, sans toutefois présenter de risques d'exposition des éléments mobiles à des contaminants extérieurs. An object of the present invention is to meet the disadvantages of the documents of the prior art mentioned above and in particular, first of all, to propose a vehicle headlamp equipped with moving elements but without external ice, but without the risk of exposing the moving parts to external contaminants.
Pour cela un premier aspect de l'invention concerne un projecteur de véhicule comprenant au moins une source lumineuse agencée dans un boîtier de projecteur pour émettre de la lumière et au moins une lentille extérieure agencée pour projeter vers l'extérieur du boîtier de projecteur la lumière émise par ladite au moins une source lumineuse, caractérisé en ce que le boîtier de projecteur est mobile par rapport à ladite au moins une lentille extérieure, et en ce que le projecteur comprend des moyens d'étanchéité par chicane entre ladite au moins une lentille extérieure et le boîtier de projecteur. For this purpose, a first aspect of the invention relates to a vehicle headlamp comprising at least one light source arranged in a headlight housing for emitting light and at least one outside lens arranged to project the headlight box towards the outside of the headlamp emitted by said at least one light source, characterized in that the projector housing is movable with respect to said at least one outer lens, and in that the projector comprises baffle sealing means between said at least one outer lens and the projector box.
Le projecteur selon la mise en œuvre ci-dessus est simple et peu coûteux puisqu'il est dépourvu de glace (c'est la lentille extérieure qui délimite l'extérieur du boîtier de projecteur), mais grâce aux moyens d'étanchéité par chicane, les mouvements entre le boîtier de projecteur et la lentille extérieure sont possibles. Enfin, les moyens d'étanchéité par chicane sont implantés entre le boîtier de projecteur et la lentille extérieure, ce qui permet de conserver ces éléments sans en modifier la structure interne. The projector according to the implementation above is simple and inexpensive since it is free of ice (it is the outer lens that defines the outside of the projector casing), but thanks to the sealing means baffle, movements between the projector box and the outer lens are possible. Finally, the baffle sealing means are located between the projector housing and the outer lens, which allows to retain these elements without modifying the internal structure.
Avantageusement, les moyens d'étanchéité par chicane comprennent : Advantageously, the baffle sealing means comprise:
- au moins une paroi solidaire de l'un du boîtier de projecteur ou de la lentille extérieure,  at least one wall integral with one of the projector housing or the outer lens,
- au moins une fente solidaire de l'autre du boîtier de projecteur ou de la lentille extérieure,  at least one slot integral with the other of the projector housing or the outer lens,
ladite au moins une fente étant agencée pour recevoir ladite au moins une paroi et définir ainsi au moins une chicane. said at least one slot being arranged to receive said at least one wall and thus define at least one baffle.
Avantageusement, au moins l'une de ladite au moins une paroi ou de ladite au moins une fente est souple, de sorte à se déformer lors d'un mouvement relatif entre le boîtier de projecteur et la ladite au moins une lentille extérieure. En plus de la mobilité intrinsèque des moyens d'étanchéité par chicane, ceux-ci sont suffisamment souples pour se déformer et offrir plus de mouvements entre les pièces mobiles. Advantageously, at least one of said at least one wall or of said at least one slot is flexible, so as to deform during a relative movement between the projector housing and said at least one outer lens. In addition to the intrinsic mobility of the sealing means by baffle, these are flexible enough to deform and offer more movement between moving parts.
Avantageusement, les moyens d'étanchéité par chicane sont agencés pour permettre une liaison rotule entre la lentille extérieure et le boîtier de projecteur. Advantageously, the baffle sealing means are arranged to allow a ball joint connection between the outer lens and the projector housing.
Avantageusement, ladite au moins une source lumineuse est du type à diode électroluminescente. Advantageously, said at least one light source is of the light emitting diode type.
Avantageusement, les moyens d'étanchéité par chicane présentent une symétrie de révolution autour d'un axe de projection de lumière d'azimut médian et de hauteur médiane. L'axe médian est situé à mi-course dans chacune des directions de réglage. Advantageously, the baffle sealing means have a symmetry of revolution about a median azimuth light projection axis and median height. The middle axis is located halfway in each of the adjustment directions.
Avantageusement, le projecteur de véhicule comprend des moyens de dissipation thermique accouplés à ladite au moins une source lumineuse. On peut envisager un radiateur, une pièce métallique ou fortement conductrice de la chaleur. Advantageously, the vehicle headlight comprises heat dissipation means coupled to said at least one light source. It is possible to envisage a radiator, a metal part or a strong conductor of heat.
Avantageusement, le projecteur de véhicule comprend au moins un moteur de réglage d'un axe d'azimut et/ou de hauteur de projection lumineuse. Advantageously, the vehicle headlight comprises at least one motor for adjusting an azimuth axis and / or height of light projection.
Avantageusement, le projecteur de véhicule est dépourvu de glace. Un second aspect de l'invention est un véhicule automobile comportant au moins un projecteur de véhicule selon le premier aspect de l'invention. Advantageously, the vehicle headlamp is devoid of ice. A second aspect of the invention is a motor vehicle comprising at least one vehicle headlight according to the first aspect of the invention.
D'autres caractéristiques et avantages de la présente invention apparaîtront plus clairement à la lecture de la description détaillée qui suit d'un mode de réalisation de l'invention donné à titre d'exemple nullement limitatif et illustré par le dessin annexés, dans lequel : Other features and advantages of the present invention will appear more clearly on reading the following detailed description of an embodiment of the invention given as a non-limitative example and illustrated by the appended drawing, in which:
- la figure 1 représente une vue en coupe d'un projecteur selon l'invention. La figure 1 représente un projecteur de véhicule comprenant notamment un boîtier 10 qui renferme une source lumineuse 20, ici une ou plusieurs diode(s) électroluminescente(s) par exemple, qui est agencée pour émettre de la lumière afin de projeter un faisceau lumineux de type feu de croisement ou feux de route par exemple. - Figure 1 shows a sectional view of a projector according to the invention. FIG. 1 shows a vehicle headlamp comprising in particular a housing 10 which encloses a light source 20, here one or more electroluminescent diode (s) for example, which is arranged to emit light in order to project a light beam of type of low beam or high beam for example.
La source lumineuse 20 peut également être une lampe halogène ou une ampoule à filament classique. Dans le cas où une technologie à diode est retenue, la source lumineuse peut être montée sur des moyens de dissipation thermique 60, comme un radiateur en aluminium par exemple. Afin de guider la lumière émise par la source lumineuse 20, le projecteur comprend des moyens de guidage de la lumière, ici sous la forme d'une coque 50 réfléchissante recouvrant la source lumineuse 20. Afin de projeter vers l'extérieur du projecteur un faisceau lumineux répondant aux normes en la matière, le projecteur comprend une lentille extérieure 30 qui reçoit la lumière émise par la source lumineuse 20 et guidée par la coque 50, la focalise selon les critères requis pour former un faisceau lumineux adéquat (en feux de croisement ou en feux de route). The light source 20 may also be a halogen lamp or a conventional filament bulb. In the case where a diode technology is selected, the light source can be mounted on heat dissipation means 60, such as an aluminum radiator, for example. In order to guide the light emitted by the light source 20, the projector comprises light guiding means, here in the form of a reflective shell 50 covering the light source 20. In order to project the beam to the outside of the projector the luminaire meets the standards in the field, the projector comprises an outer lens 30 which receives the light emitted by the light source 20 and guided by the hull 50, the focuses according to the criteria required to form a suitable light beam (in low beam or in high beam).
Comme le projecteur représenté ne comprend pas de glace, la lentille extérieure 30 est donc directement exposée aux agressions extérieures, comme des grains de sable, des gravillons, ou de l'eau. As the projector shown does not include ice, the outer lens 30 is therefore directly exposed to external aggression, such as grains of sand, chippings, or water.
La source lumineuse 20, la coque 50 et la lentille extérieure 30 peuvent tous être monté sur un châssis 80 afin de former un module embarquant ces éléments. The light source 20, the shell 50 and the outer lens 30 can all be mounted on a frame 80 to form a module carrying these elements.
Le projecteur est également équipé de moyens de réglage de l'orientation du faisceau lumineux émis par la lentille extérieure 30, comme par exemple un ensemble moteur 70 - vis sans fin 75 qui permet de régler la hauteur du faisceau lumineux projeté. On peut imaginer une liaison pivot entre le boîtier de projecteur 10 et le châssis 80 (et donc la lentille extérieure 30), si seule la hauteur est réglable, mais également une liaison rotule si un angle d'azimut par rapport au véhicule est également réglable. Dans ce cas, ou pour d'autres raisons de réglage, il faut laisser un mouvement possible entre le boîtier de projecteur 10 et la lentille extérieure 30. Ce mouvement ne doit pas compromettre l'étanchéité de l'intérieur du boîtier de projecteur 10, et l'invention propose d'implanter des moyens d'étanchéité par chicane 40 entre la lentille extérieure 30 et le boîtier de projecteur 10. The projector is also equipped with means for adjusting the orientation of the light beam emitted by the outer lens 30, such as for example a motor 70 - worm 75 which adjusts the height of the projected light beam. One can imagine a pivot connection between the projector box 10 and the frame 80 (and therefore the outer lens 30), if only the height is adjustable, but also a ball joint if an azimuth angle to the vehicle is also adjustable . In this case, or for other reasons of adjustment, it is necessary to allow a possible movement between the projector box 10 and the outer lens 30. This movement must not compromise the tightness of the interior of the projector box 10, and the invention proposes to implement baffle sealing means 40 between the outer lens 30 and the floodlight box 10.
Ces moyens d'étanchéité par chicane 40 comprennent deux parois 42 successives liées à la lentille extérieure 30, qui s'insèrent dans deux fentes 41 successives, liées pour leur part au boîtier de projecteur 10. Le trajet de fuite est alors considérablement augmenté, et on peut envisager en plus de forcer un contact entre les pièces. Par ailleurs; ces moyens d'étanchéité par chicane 40 permettent de conserver le boîtier de projecteur 10, son intérieur (le module supporté par le châssis 80), ainsi que la lentille extérieure 30 standards, afin de limiter l'impact sur les coûts. Afin de permettre les mouvements de réglage susmentionnés (hauteur et/ou azimut), on peut également envisager de prévoir les parois 42 et/ou les fentes 41 souples pour les laisser se déformer lors d'un réglage. These baffle sealing means 40 comprise two successive walls 42 connected to the outer lens 30, which fit into two successive slots 41, for their part connected to the floodlight box 10. The leakage path is then considerably increased, and we can consider in addition to force a contact between parts. Otherwise; these baffle sealing means 40 retain the projector housing 10, its interior (the module supported by the frame 80), and the outer lens 30 standards, to limit the impact on costs. In order to allow the aforementioned adjustment movements (height and / or azimuth), it is also possible to envisage the walls 42 and / or the flexible slots 41 to be deformed during an adjustment.
On comprendra que diverses modifications et/ou améliorations évidentes pour l'homme du métier peuvent être apportées aux différents modes de réalisation de l'invention décrits dans la présente description sans sortir du cadre de l'invention défini par les revendications annexées. It will be understood that various modifications and / or improvements obvious to those skilled in the art can be made to the various embodiments of the invention described in the present description without departing from the scope of the invention defined by the appended claims.
