    专利说明:

    [0001] The present invention relates generally to a headlamp for mounting on a motor vehicle. It is known in the prior art of road lighting devices mounted on a motor vehicle. These devices are usually part of a headlamp or headlamp located at the front of the vehicle and projecting a light beam towards the front of the vehicle to illuminate the road. In general, these devices comprise a lighting module including a light source, a reflector, a printed circuit board in the case of a light-emitting diode as a light source, a lens for projecting the light emitted towards the front and a light-emitting diode. ice in front to protect the device. A problem with these devices is that they are too rigid in terms of modularity. Indeed, a lighting module emits a single type of beam so that the photometry of the projector, that is to say the area illuminated in front of the vehicle, is static regardless of the traffic condition unless you use an element such as a mask, a screen or a barrel which makes the system and its manufacture more complicated. To remedy this type of disadvantage, it has been found to use several modules in the same projector, each of these modules emitting a particular beam for more modularity for example by changing their shape, via a mask, or their intensity as described in US 2001/0028565. On the other hand, a problem of this type of device is that it allows a certain lighting modularity but at the cost of a performance resulting from an optical compromise of the projectors due to the number of functionalities / photometric distributions to be achieved. Transient phases between the different photometric distributions also cause genes on the road during a transition from one state to another.
    [0002] An object of the present invention is to meet the drawbacks of the document of the prior art mentioned above and in particular, firstly, to provide an economical vehicle headlight, simple to implement and able to provide a photometry scalable and combining multiple features at optimal performance levels. For this purpose, a first aspect of the invention relates to a vehicle headlamp comprising a main lighting module arranged to emit a main light beam corresponding to a dipped beam / road light, a plurality of complementary lighting modules arranged to emit each one. a complementary light beam different from the main light beam, a setting means in azimuth and elevation of each of the lighting modules, and a control unit, characterized in that the adjustment means in elevation and azimuth is arranged for orienting each of the field and azimuth lighting modules independently of each other in response to an order from the control unit. In this way, an easy-to-use projector is provided which allows for a flexible photometry with optimum performance levels. Advantageously, the main lighting module is arranged to emit a flat-cut light beam and in that at least one of the complementary modules is arranged to project a symmetrical breaking beam adjacent to a front side of the light beam. with flat cut-off so as to complement the flat-cut light beam for right-hand drive (DaG) / left-hand drive (DaD). Thus, we increase the modularity of the projector.
    [0003] A particularly interesting embodiment consists in that the complementary module is orientable in azimuth so as to horizontally move the cut-off beam between the lateral ends of the flat-cut light beam. In this way, we can move from one country to another that does not respect the same side of driving without the need to change the projector.
    [0004] Advantageously, at least one other complementary module is arranged to project an adjacent beam to a lateral face of the main beam and in that the other complementary module is orientable so as to horizontally move the beam of a lateral face of the main beam. to the other. Thus, a uniform overall beam is obtained. Advantageously, the complementary modules are arranged to sequentially project their beam so as to superpose the complementary beams sequentially with the main beam. In this way, it is possible to obtain superior glare from light sources and an alternative to lighthouse calls that is more efficient in terms of perception by drivers coming from the front or pedestrians on the aisles. A particularly interesting embodiment consists in that at least one of the complementary modules is arranged so as to emit a beam able to move in order to follow an identified target. Thus, night safety is improved. Advantageously, at least one of the complementary modules is arranged to project a beam so as to make it adjacent to a side face of the main beam. In this way, the driver's illuminated field of vision can be enlarged. Advantageously, at least two complementary modules are arranged to each project a beam on either side of the main beam. Thus, the driver's field of vision can be further expanded. A particularly interesting embodiment consists in that at least one of the complementary modules is arranged to project a beam so as to superpose it with a main beam of the main module. In this way, one can either save a light source for the high beam or increase the photometric performance.
    [0005] A second aspect of the invention is a vehicle comprising a projector 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 drawings, in which: Fig. 1 shows a projector according to an embodiment of the present invention. FIGS. 2A and 2B show a first photometry embodiment of the projector of the present invention; FIGS. 3A to 3C show three other photometry embodiments of the projector of the present invention; FIG. vehicle 1 according to an embodiment of the present invention. As shown, this headlamp comprises a main module 2 arranged to emit a main light beam 31, 41, 51, 61, preferably a high beam / cross light, that is to say it is a bifunctional module capable of emitting a passing beam or a driving beam, which comprises one or more motors (not visible) arranged to adjust it in elevation and in azimuth according to the vertical and horizontal arrows of FIG. 1. Although this is not visible on the 1, the main beam crossing may be flat cut, ie its photometry (illumination zone) is substantially rectangular without enlarged illumination zone for the low side of the road or cut at X ° (For example 15 °) so that the main beam also illuminates the low side of the road.Also, this projector comprises a plurality of complementary modules 3, 3 ', 3 "arranged to each emit a complementary light beam area 32, 33, 34, 42, 43, 44, 52, 53, 54, 62, 63, 64 different from the main light beam. By different from the main beam, it is understood the shape of the beam, its intensity or the like. The complementary modules 3, 3 ', 3 "preferably each comprise a motor arranged to adjust the complementary module for which it is intended in site and in azimuth independently of each other as represented by the vertical and horizontal arrows.
    [0006] Indeed, the projector 1 also comprises a setting means 4, which may include the motors mentioned above, to adjust in site and in azimuth each of the lighting modules 2, 3, 3 ', 3 ", main and complementary, and a control unit (not shown) for issuing an order to the setting means 4 for orienting each of the lighting modules 2, 3, 3 ', 3 "in elevation and azimuth independently of one another. FIGS. 2A and 2B show a particular embodiment of the present invention in which the main lighting module 2 is arranged to emit a flat-cut light beam 31. Thus the beam of the main module does not illuminate an additional area of the lower side of the road further ahead not related to the rest of the road. However, at least one of the complementary modules 3, 3 ', 3 "is arranged to project a symmetrical breaking beam 34 adjacent to a front side of the flat-cut light beam so as to complement the flat-cut light beam. In addition, since the complementary module 3, 3 ', 3 "is orientable in azimuth, the adjusting means can horizontally move the symmetrical breaking beam 34 between the ends. side of the light beam cutoff 31 illuminate, either a low side left or right of the vehicle thus implementing a management DAD / DAG (direction right / left direction). In addition, as shown in FIGS. 2A and 2B, at least one other complementary module 3, 3 ', 3 "is arranged to project a beam 32, 33 adjacent to a lateral face of the main beam 31. In the figures, two complementary beams , one on each side, are emitted.This other complementary module is also steerable so as to horizontally move the beam from one side face of the main beam to the other.In the case of Figure 2A and Figure 2B among the two beams, one of the two has a rectangular shape, which allows at least partially superimpose it with the main beam and the symmetrical beam cutoff so as to standardize the dipped beam and is therefore preferably moved together with the Cut-off light 34. FIG. 3A shows another embodiment of the invention in which the complementary modules 3, 3 ', 3 "are arranged to sequentially project their isceau 42, 43, 44 so as to superpose the complementary beams sequentially with the main beam 41. Figure 3C shows another embodiment of the invention in which at least one of the complementary modules 3, 3 ', 3 " is arranged to be able to emit a beam 72 able to move along the horizontal and vertical arrows, so as to follow a target identified, preferably, by an obstacle detector or the like. FIG. 3B represents another embodiment of the invention in which at least one of the complementary modules 3, 3 ', 3 "is arranged to project a beam 53, 54, 55 so as to make it adjacent to a face side of the main beam 51, preferably at least two complementary modules 3, 3 ', 3 "are arranged to each project a beam 52, 53, 54 on either side of the main beam 51. Other embodiments are also possible, such as one in which at least one of the complementary modules 3, 3 ', 3 "is arranged to project a beam so as to superimpose it with a main beam of the main module. 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.reference is made to different types of light sources, number of modules, types of motor and materials used, etc.
