    The invention relates to the field of lighting, in particular for a motor vehicle. More particularly, the invention relates to the field of projectors for a motor vehicle.
    The published patent document US 2005/0068787 A1 discloses a lighting module comprising two optical systems arranged in opposite manner. Each of these two optical systems essentially comprises a light source and a reflective surface. These two light sources are arranged on two opposite faces of a common support. Each of the reflecting surfaces is a surface of revolution in a half-space delimited by the common support. The two reflecting surfaces thus form two half-shells opposite to each other. One of the two optical systems is configured to form a horizontal cut-off lighting beam, corresponding to a beam called "code" (in English "low-beam"). To do this, the module comprises a reflective surface with a so-called "cut-off" edge located at a focus of the reflecting surface. The rays meeting the surface in question at the rear of the cutting edge are reflected towards an upper part of a projection lens whereas those passing at the front of the edge in question are not deflected and meet a lower part of the projection. lens in question. This phenomenon ensures a cut, essentially horizontal, of the beam. The other of the two optical systems operates essentially in the same way, with the difference that its configuration is symmetrical to that of the first system. The beam produced by the second optical system is combined with that of the first system to produce a "high-beam" light beam, that is to say a horizontal unbroken beam. This configuration is interesting in that it exploits the cut-off beam to produce a "road" type beam. However, it may have photometric difficulties in the lower part of the "road" type beam, given that it is essentially provided by the "code" type cut-off beam.
    The published patent document US 2007/0279924 A1 discloses a lighting module for a motor vehicle, comprising a light source with several light zones able to be powered separately. It also includes a reflective surface forming a half-shell, similar to the reflective surfaces of the previous teaching. The image produced with the illumination beam varies according to the light areas that are fed. A vertically limited and horizontally spread beam can be produced as well as a more vertically extended and horizontally limited beam. This teaching is interesting in that the shape of the beam can be modulated by the light source. The invention aims to overcome at least one of the disadvantages of the state of the art, in particular the state of the art mentioned above. More particularly, the object of the invention is to propose a high-performance lighting module capable of producing a cut-off beam and, in combination with the cut-off beam, an unbroken beam.

    According to an advantageous embodiment of the invention, the module comprises a lens configured to receive light rays from the first and second optical systems in order to form the first and second beams. The invention may also relate to a projector comprising a module according to the invention.
    The measurements of the invention are interesting in that they make it possible to produce, in addition to a first cut-off beam, a second unbroken beam and with a greater luminous flux, and this thanks to the first optical system. Other features and advantages of the present invention will be better understood from the description and the drawings, among which: FIG. 1 is a block diagram of a lighting module according to a first embodiment of FIG. the invention; FIG. 2 illustrates the image of a horizontally cut beam produced by the module of FIG. 1; FIG. 3 illustrates the image of a horizontal unbroken beam produced by the module of FIG. 1; FIG. 4 is a schematic view in elevation of the upper light zones of the module of FIG. 1; FIG. 5 is a schematic view in elevation of the upper light zones of a lighting module according to a second embodiment of the invention.
    Figure 1 is a schematic representation of a lighting module according to the invention. The module 2 comprises an optical axis 4, a first optical system 6, a second optical system 20 and a lens 18. The first and second optical systems 6 and 20 are opposed to each other, on either side of the optical axis 4.
    The first optical system 6 comprises, essentially, a light source 8 disposed on a support 10, and a reflecting surface 12. This forms a half-shell in the half-space defined by the support 10. The latter is advantageously generally plane . The reflecting surface 12 advantageously has an elliptical profile with two focal points Fi and F2, one (Fi) corresponding to the location of the light source 8 and the other (F2) being at a cut-off edge 14. a reflective surface 16.
    The second optical system 20 comprises, essentially and similarly to the first optical system 6, a light source 22 disposed on the support 10 which is advantageously common with the first light source 8, and a reflecting surface 24. The latter forms a half-shell in the half-space delimited by the support 10 and is preferably of elliptical profile with two foci F- / and F2, one (F · /) corresponding to the location of the light source 22 and the other (F2) being at the cut-off edge 14 of the reflecting surface 16. The focus F2 of the second optical system 20 may be coincident with that (F2) of the first optical system 6.
    The reflecting surfaces 12 and 24 of the first and second optical systems 6 and 20 may be surfaces of revolution, configured to reflect the rays emitted in the two half-spaces delimited by the support 10 to the foci F2 and f2 '.
    With reference to FIG. 1, it can be observed that the first light source 8 comprises several light zones 81 and 82 that are distinct from one another. In this case, the main light zone or zones 81 are arranged at the first focus F1 while the auxiliary light zone or zones 82 are arranged in front, in the direction of the optical axis and the general direction of the ray path, of zone (s) 81 located in focus Fi.
    The operation of the module is as follows:
    When the main light zone (s) 81 of the light source 8 of the first optical system is / are electrically powered, the rays produced are essentially reflected towards the second focus F2. Part of the rays pass directly to the front of the cutting edge 14 and meet the lower half of the lens 18. These rays are then refracted a first time to the passage of the first diopter formed by the rear face of the lens and then a second once at the passage of the second diopter formed by the front face of said lens. These rays are illustrated by the ray shown in solid lines in Figure 1. Another portion of the rays meet the reflecting surface 16 at the rear of the cut-off edge 14 and are reflected towards the upper half of the lens 18. These rays are then refracted a first time to the passage of the first diopter of the lens and then a second time to the passage of the second diopter. These rays, if they were not reflected towards the upper half of the lens, would meet the lower half of the lens in such a way that they would be refracted towards the top of the beam at the exit of the lens. Reflecting them by means of the reflecting surface 16 effects a substantially horizontal cut of the beam. This phenomenon is well known in itself to those skilled in the art. These rays are illustrated by the rays represented in broken lines. A beam with an image as shown in Figure 2 is then produced. It can be seen that this beam has a substantially horizontal cut, the area above the cut in question being very little or no light, while the area below the cut is illuminated.
    When the light source 22 of the second optical system is electrically powered, a beam complementary to the beam of the first optical system is produced. When the light source 22 of the second optical system is electrically powered at the same time as the main light areas 81 of the first optical system, a beam such as that shown in solid lines in Figure 3 is produced. In order to achieve photometric values desired for a high-beam lighting function, the auxiliary light areas 82 of the light source 8 of the first optical system 6 are also electrically powered. The beam produced by the first optical system 6 is then more intensely photometrically and then makes it possible to produce a lighting beam corresponding to the image shown in broken lines in FIG. 3. This beam is not only more wide, especially in its lower part, but also more intense than the beam produced with the two optical systems 6 and 20 when only the main light areas 81 of the first system 6 are fed. The increase in luminous intensity is advantageously concentrated on the hatched area in FIG. 3, the height of which corresponds to 3% of slope downwards from the horizontal and whose width corresponds to 20% of slope. The average luminous flux in this zone can go from 120 Lm to 170 Lm. The increase in this zone is advantageously greater than or equal to 50%.
    With reference to FIG. 1, the auxiliary light zone or zones 82 (which are only powered in combination with that of the second optical system 20) are advantageously arranged in the direction of the optical axis and the direction of the optical axis. light ray path, at the front of the main light zones 81. The path of a ray from one of the auxiliary light zones 82 is illustrated in broken lines in FIG. 1. It can be observed that the ray emitted by the light zone 82 after reflection on the reflecting surface 12, meets the reflecting surface 16 behind the cutoff edge 14 and is reflected towards the upper half of the lens 18. It encounters the lens 18 with an angle of incidence less than that of the corresponding ray, also in broken lines, coming from one of the main light zones 81. The ray coming from the auxiliary light zone 82, situated in front of the light zones 81, fate of the lens 18 in a direction directed downwards. Positioning the auxiliary light zone (s) at the front of the main light zone (s), more particularly at the front of the first focus Fi, thus makes it possible to increase the luminous intensity near the horizontal cutoff, in the lower part of the beam produced.
    FIG. 4 is an elevational view of the upper face of the support 10 of the light source 8 of the first optical system 6 of FIG. 1. It can be observed that the light source 8 comprises four main light zones 81 arranged along a first direction 26 perpendicular to the optical axis 4. The auxiliary light areas 82 are two in number and are also arranged in a second direction 28 perpendicular to the optical axis 4, this direction being located in front of the first direction perpendicular 26. The distance d between these two perpendicular directions 26 and 28 may be between 0.5 and 3 mm, preferably between 1 and 2 mm. Still with reference to FIG. 4, it can be observed that the distance d in question corresponds to the radius r of a circle centered on the first focus Fi and through which the second perpendicular direction 28 passes. The main light zones 81 are advantageously distributed according to the first perpendicular direction 26 on the diameter 2r of the circle. This arrangement is particularly interesting from an optical point of view because the main light zones 81, being aligned along the perpendicular direction 26 passing through the first focus Fi ensure that the rays produced are concentrated towards the cutting edge at the second focus F2 and, therefore, a homogeneous beam with a sharp horizontal cut.
    FIG. 5 is a representation similar to that of FIG. 4 of a configuration of the first optical system of the module of FIG. 1 according to a second embodiment of the invention. The reference numerals of the first embodiment according to FIGS. 1 to 4 are used for the identical or corresponding elements, these numbers however being increased by 100. Reference is also made to the description of these elements in the context of the first embodiment. of realization. Specific reference numbers from 100 to 200 are used for specific elements.
    The first optical system 106 illustrated in FIG. 5 comprises two light sources 108 disposed laterally, on either side, of the optical axis 104 of the module. These light sources 108 are arranged in such a way that their light rays converge towards the second focus F2 on the optical axis 104 of the module. To do this, the reflecting surface 112 forms two portions of half-shell-shaped surfaces, preferably in an elliptical profile with two focal points Fi and F2. The two surface portions are advantageously portions of surface of revolution around the optical axes 105 and 107 of the optical system 106, said axes converging towards the second focus F2. Each of the two light sources 108 is arranged at the first focus F 1 on the corresponding optical axis 105 and 107. A lens similar to the lens 10 of FIG. 1 is disposed in front of the second focus F 2, more particularly so as to what his home corresponds to the home F2 in question.
    Similarly to the light source 8 of the first embodiment, the light sources 108 each comprise main light areas 1081 and auxiliary light areas 1082. Similar to the configuration of the first mode illustrated in FIG. 5, the main light areas 1081 may be aligned in a first direction 126 perpendicular to the corresponding optical axis 105 or 107. Still similarly to the first embodiment, the auxiliary light areas 1082 may be arranged in front of the main light areas 1081, preferably aligned in a second direction 128 perpendicular to the corresponding optical axis. In this case, the auxiliary light areas 1082 are two in number and the main light areas 1081 are four in number, and this for each of the two light sources 108. It is of course understood that these numbers may vary. It is interesting to note that the auxiliary light zones 1082 are arranged laterally with respect to the corresponding optical axis 105 or 107, on the optical axis 104 side of the module. This configuration is interesting in that this lateral offset of the auxiliary light areas 1082 makes it possible to focus the rays horizontally towards the center of the beam.
    The distance d between the two perpendicular directions 126 and 128 may be between 0.5 and 3 mm, preferably between 1 and 2 mm. It can be seen in FIG. 5 that the distance d in question corresponds to the radius r of a circle centered on each of the first foci Fi and through which the second perpendicular direction 128 passes. The main light zones 1081 are advantageously distributed in the first direction perpendicular 126 on the diameter 2r of the circle.
    In general, the light zones of the light source (s) of the first optical system can be located on the same semiconductor component, these zones then being addressable from an activation point of view, so that they can be powered individually. . Alternatively, these zones may correspond to several distinct semiconductor components, in which case these components are powered individually, for example by means of electrically conductive tracks on a board common to these components.
    Still generally, a control unit (not shown) is advantageously electrically connected to the light sources of the first and second optical systems, and configured to supply only the main light areas of the first source or sources to produce the cut-off beam. horizontal and all the light areas of the first source or sources, and the second source to produce the beam without horizontal cut.
