    专利说明:

    [0001] The present invention generally relates to a light projector mounted on a motor vehicle, otherwise called a headlight. In general, motor vehicles are equipped with headlights that allow improved night vision. EP2325883 discloses such a type of known lighthouse. It comprises a housing with one or more light sources which can be of different types (LED, halogen lamp or conventional filament bulb) and lenses and / or reflectors arranged to direct the light emitted by the light sources into a particular direction. In addition, the front of the housing (that is to say the face to which the light is projected or guided) is a transparent glass that allows to project the light to the outside of the projector, while ensuring a good seal to the case. This ice protects azimuth adjustment elements and / or height (here called site) projection provided in the housing of external contaminants, such as sand, chippings or water for example. However, this transparent glass which is generally bonded to the walls of the housing and has several disadvantages. Indeed, it has a certain resistance to the transmission of light so that it transmits only a part of the light it receives (up to 10% of the light is absorbed by such ice) and it can become opaque in time so as to absorb even more light. Finally, it is an element reported to the lighthouse and requires a fixing step which increases the costs of the projector because it requires a complex and expensive bonding process. In addition, in such a headlight the means for adjusting the azimuth (left right direction), the fixed point and the site (up-high direction) are bulky and complicated to implement because they require at least three attachment points to the case.
    [0002] 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 devoid of outer ice while decreasing the clutter of the adjustment systems. For this purpose, a first aspect of the invention relates to an ice-free vehicle headlamp comprising an optical module including at least one light source arranged to emit light and an external lens arranged to project the light emitted by said at least one light source towards the outside of the optical module, and two adjustment means arranged to provide adjustment of the azimuth and the location of the optical module, respectively, characterized in that it further comprises a single connecting element of the ball type, and the optical module is connected to the two adjustment means via the ball-type connection element. The projector according to the implementation above is simple and inexpensive since it is devoid of ice (it is the outer lens that defines the front face of the optical module) and thanks to the connecting element type ball joint, the means for adjusting the azimuth and the site are less cumbersome because it removes the fixed point of the projectors of the state of the art.
    [0003] Advantageously, the ball-type connecting element comprises a first ball-type element and a second sphere-type element, the first ball-type element being arranged inside the second sphere-type element in a mobile manner. In this way, the movement of one relative to the other can be along two perpendicular axes.
    [0004] A particularly interesting embodiment is that the first ball-like element has a substantially annular shape and is mounted on a periphery of the optical module and the second sphere-like element has a substantially annular shape and is connected to the adjustment elements. In this way, we keep the optical module without modifying the internal structure.
    [0005] Advantageously, the first ball-type element and the second sphere-type element are concentric. Thus, we gain space. Advantageously, the ball-type connection element has a rotational symmetry about an axis perpendicular to the median axis of projection of median and median height azimuth. The middle axis is located halfway in each of the adjustment directions. Thus, the optical module is reliably moved. A particularly interesting embodiment is that said at least one light source is of the light emitting diode type. Advantageously, the vehicle headlight further comprises a housing arranged to be fixed on the vehicle body and the ball-type connecting element is arranged to fix the optical module to the housing. Thus, the optical module is protected.
    [0006] Advantageously, the vehicle headlight comprises a motor for adjusting the azimuth axis and / or the height of the optical module. In this way, the settings are made automatically. A particularly interesting embodiment is that further 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. A second aspect of the invention is a motor vehicle comprising an ice-free projector according to the first aspect of the invention. Other features and advantages of the present invention will become more apparent upon reading the following detailed description of an embodiment of the invention given by way of non-limiting example and illustrated by the accompanying drawings, in which: - Figure 1 shows a sectional view of a projector according to the invention.
    [0007] FIG. 1 shows an ice-free vehicle headlamp including an optical module 10 which encloses a light source 20, in this case one or more light-emitting diode (s) for example, which is arranged to emit light in order to project a light beam of the low beam type 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 retained as shown in Figure 1, the light source can be mounted on heat dissipation means 80, 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 90 covering the light source 20. In order to project the beam to the outside of the projector The luminaire, which meets the standards in the field, comprises an outer lens 30 which receives the light emitted by the light source 20 and guided by the shell 90, and focuses it 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 grains of sand, chippings, or water. The projector is also equipped with two adjustment means 50 and 60 for the orientation of the light beam emitted by the outer lens 30, which makes it possible to adjust the height (or the site) and the azimuth respectively of the projected light beam via a single ball-type connection element 40 which connects them to the optical module. These adjustment means can be manual or controlled by a motor (not shown) Also, as shown, the headlamp can be equipped with a housing 70 arranged to be fixed to a vehicle body and the ball joint type connecting element. 40 is arranged to fix the optical module 10 inside the housing via the connecting elements 50 and 60. Alternatively, it can be directly attached to the vehicle structure, the housing 70 can then be absent. structure of the ball-type connection element, in FIG. 1 it can be seen that the ball-type connection element 40 comprises a first ball-type element 41 which can be mounted on the optical module or be integral with it and a second sphere-like member 42 which is operatively attached to the adjusting means, the first ball-like member being disposed within the second sphere-like member in a movable manner. Preferably, the first ball-like element 41 has a substantially annular shape and is mounted or integral, on one periphery of the optical module 10 and the second sphere-like element 42 has a substantially annular shape and is connected to the adjusting elements and the first ball-like element 41 and the second sphere-like element 42 are concentric so that the ball-type connecting element 40 has rotational symmetry around a perpendicular to the median axis of light projection. of median azimuth and median height. In FIG. 1, the connecting element 40 is on the back of the optical module, however, it can be placed at the front, for example at the boundary 20 between the optical module and the lens. and / or obvious improvements for 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.
