    专利说明:

    [0001] The present invention generally relates to a light projector mounted on a motor vehicle, otherwise called a headlight. EP2325883 discloses a known type of projector, with a housing containing one or more light sources (LED type 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 water for example. This transparent glass is generally bonded to the walls of the housing and has several drawbacks: it transmits only a part of the light it receives (up to 10% of the light is absorbed by such ice); it can become opaque in time (and absorb more light), - it increases the costs of the projector, 20 - it requires a complex and expensive process of gluing, - it hides or masks the technical elements of the projector of the outside, which limits the external signature of the vehicle. An object of the present invention is to meet the drawbacks 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 devoid of external ice, without However, there is a risk of exposure of the moving parts to external contaminants. For this purpose, a first aspect of the invention relates to a vehicle headlamp comprising at least one light source arranged in a headlamp housing for emitting light and at least one outside lens arranged to project the headlamp housing towards the outside. light 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 exterior lens and the projector box. The projector according to the above implementation 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 baffle sealing means. 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. Advantageously, the baffle sealing means 20 comprise: at least one integral wall of one of the projector housing or the outer lens, at least one slot integral with the other of the projector housing or the lens outer, said at least one slot being arranged to receive said at least one wall and thus define at least one baffle. Advantageously, at least one of said at least one wall or said at least one slot is flexible, so as to deform upon relative movement between the projector housing and said at least one outer lens. In addition to the intrinsic mobility of the baffle sealing means, these are sufficiently flexible to deform and offer more movement between the moving parts. Advantageously, the baffle sealing means are arranged to allow a ball joint connection between the outer lens and the projector housing. Advantageously, said at least one light source is of the light emitting diode type. Advantageously, the baffle sealing means have a symmetry of revolution about a median and median height azimuth light projection axis. The middle axis is located halfway in each of the adjustment directions. Advantageously, the vehicle headlight comprises heat dissipation means coupled to said at least one light source. A radiator, a metal part or a highly conductive member of the heat can be envisaged. Advantageously, the vehicle headlight comprises at least one motor for adjusting an azimuth axis and / or height of light projection. Advantageously, the vehicle headlamp is devoid of ice. A second aspect of the invention is a motor vehicle having at least one vehicle headlight according to the first aspect of the invention. 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 by way of non-limiting example and illustrated by the appended drawing, in which - Figure 1 shows a sectional view of a projector according to the invention.
    [0002] 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. 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.
    [0003] 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). Since the projector shown does not include ice, the outer lens 30 is therefore directly exposed to external aggression, such as sand grains, chippings, or water. 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. 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 assembly 70 - worm 75 which makes it possible to adjust 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 with respect to the vehicle is also adjustable.
    [0004] 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. These baffle sealing means 40 comprise two successive walls 42 connected to the outer lens 30, which insert in two slots 41 successive, for their part linked to the projector housing 10. The leakage path is then greatly increased, and we can consider in addition to force a contact between the 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.
    [0005] 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. 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 herein without departing from the scope of the invention defined by the appended claims.
