Lighting device for a motor vehicle
The invention relates to a luminous device of a motor vehicle, the device including a first luminous module with first and second sub-modules each provided with a light source, and a collector, the first module including a lens which is designed to project the light reflected by the collectors in light beams with a upper cut-off offset vertically from each other.
1. A luminous device of a motor vehicle, comprising:
a first luminous module including a first sub-module provided with a first light source and a first collector designed to collect and reflect light emitted by the first light source;
a lens designed to project light reflected by the first collector in a first light beam with a first upper cut-off, the first light beam being formed by an image of the reflective surface of the first collector formed by the lens;
a second sub-module provided with a second light source and a second collector designed to collect and reflect light emitted by the second light source, wherein each of the first and second collectors has a rear edge;
the rear edge of the first collector being offset vertically in relation to the rear edge of the second collector:
wherein the lens has a focal area situated in a vicinity of the rear edge of the second collector;
the lens being designed to project light reflected by the second collector in a second light beam with a second upper cut-off;
the second light beam being formed by an image of the reflective surface of the second collector formed by the lens; with the first and second sub-modules being designed such that the first upper cut-off is offset vertically in relation to the second upper cut-off.
2. The luminous device of claim 1 ,
wherein the lens is designed such that the first light beam has an upper cut-off formed by the image of the rear edge of the first collector formed by the lens, and such that the second light beam has an upper cut-off formed by the image of the rear edge of the second collector formed by the lens.
3. The luminous device of claim 2 , wherein the first and second light sources are fitted on a same support.
4. The luminous device of claim 1 , wherein the first luminous module includes a plurality of first sub-modules; each provided with a first light source, and a first collector including a reflective surface which is designed to collect and reflect light emitted by the first light source; and
wherein the first luminous module includes a plurality of second sub-modules, each provided with a second light source and a second collector including a reflective surface which is designed to collect and reflect light emitted by the second light source;
the first and second sub-modules being arranged in a manner which is adjacent to, and alternating with, one another.
5. The luminous device of claim 1 , further comprising a control unit which is designed to control selectively each of the first and second light sources, the control unit being designed to light one of the first and second light sources only when a respective one of the first and second light sources is switched off.
6. The luminous device of claim 1 , further comprising
a second luminous module which can emit a third light beam including a third upper cut-off with at least one flat portion, the first and second luminous modules being designed such that the flat portion of the third upper cut-off is aligned with the second upper cut-off.
7. The luminous device of claim 6 , wherein the second luminous module includes a third light source, and wherein the first, second and third light sources are fitted on a same support.
8. The luminous device of claim 7 , further comprising
a third luminous module, which is arranged below the first luminous module, and includes a third sub-module identical to the first sub-module of the first luminous module;
a fourth sub-module identical to the second sub-module of the first luminous module, and a lens which is designed to project the light emitted by the third luminous module in a fourth light beam with a fourth upper cut-off, and to project the light emitted by the fourth luminous module in a fifth light beam with a fifth upper cut-off, the third and fourth sub-modules being arranged such that the fourth upper cut-off is aligned with or superimposed on, the first upper cut-off such that the fifth upper cut-off is aligned with or superimposed on; the second upper cut-off.
9. The luminous device claim 8 , further comprising
a fourth luminous module which is configured to emit other light beam extending at least partly above the second upper cut-off.
10. A luminous device of a motor vehicle, comprising:
a first luminous module including a first sub-module provided with a first light source and
a first collector designed to collect and reflect light emitted by the first light source;
a lens designed to project light reflected by the first collector in a first light beam with a first upper cut-off, the first light beam being formed by an image of the first collector formed by the lens;
a second sub-module provided with a second light source and a second collector designed to collect and reflect light emitted by the second light source;
the lens being designed to project light reflected by the second collector in a second light beam with a second upper cut-off;
the second light beam being formed by an image of the second collector formed by the lens; with the first and second sub-modules being designed such that the first upper cut-off is offset vertically in relation to the second upper cut-off;
a second luminous module which can emit a third light beam;
a third luminous module, which is arranged below the first luminous module that includes a third sub-module identical to the first sub-module of the first luminous module and
a fourth sub-module identical to the second sub-module of the first luminous module.
