Abstract

A luminous motor-vehicle device. The luminous device includes: a segmenting part including a plurality of through-cavities; a plurality of light sources upstream of the segmenting part; a mask that blocks at least one through-cavity of the segmenting part, said mask being able to be partially passed through by light. The luminous device is arranged so that each through-cavity directly or indirectly receives light from at least one separate light source.

First claim

The invention claimed is:

1. A luminous device, said device comprising:
a segmenting part including a plurality of through-cavities;
a plurality of light sources upstream of the segmenting part; and
a mask that blocks at least one through-cavity of the segmenting part, said mask being able to be partially passed through by light,
wherein said luminous device is arranged so that each through-cavity directly or indirectly receives light from at least one separate light source, and
wherein the mask includes at least one apertured zone and in that the mask and the segmenting part are arranged with respect to each other so that the apertured zone is placed facing at least one through-cavity.

2. The luminous device according to claim 1 , wherein the mask is made from a scattering and translucent material.

3. The luminous device according to claim 1 , wherein the material from which the mask is made is dark.

4. The luminous device according to claim 1 , wherein the mask is made from a material that lets pass 5 to 20% of the light that reaches it.

5. The luminous device according to claim 1 , wherein a transparent element that lets pass a percentage of light higher than that of the mask covers the apertured zone of the mask.

6. The luminous device according to claim 1 , wherein each through-cavity is arranged facing at least one separate light source.

7. The luminous device according to claim 1 , wherein the segmenting part and the mask are spaced apart from each other.

8. The luminous device according to claim 7 , wherein the space between the segmenting part and the mask is comprised between 1.5 mm and 2.5 mm.

9. The luminous device according to claim 1 , wherein the segmenting part is covered with a reflective coating.

10. The luminous device according to claim 1 , wherein the light sources have an arrangement and connections in the luminous device allowing them to be driven independently of one another.

11. The luminous device according to claim 1 , wherein the luminous device comprises at least one device for driving the light sources.

12. The luminous device according to claim 1 , wherein the through-cavities are produced in a base of the segmenting part, the mask having an outline of similar shape to that of the peripheral edges of the base and being set into the peripheral edges so as to cover all of a front face of the base.

13. The luminous device according to claim 1 , wherein the segmenting part comprises a positioning means housed in a curved section of a lateral edge of the mask and in contact with the mask.

14. The luminous device for assembling a luminous device according to claim 1 , wherein said process comprises:
providing a luminous vehicle device comprising a segmenting part with a given number and a given arrangement of through-cavities,
choosing a mask from a plurality of masks each comprising a different number and a different arrangement of apertured zones,
mounting the chosen mask on the segmenting part.

15. The luminous device according to claim 2 , wherein the material from which the mask is made is dark.

16. The luminous device according to claim 2 , wherein the mask is made from a material that lets pass 5 to 20% of the light that reaches it.

17. The luminous device according to claim 2 , wherein each through-cavity is arranged facing at least one separate light source.

18. The luminous device according to claim 2 , wherein the segmenting part and the mask are spaced apart from each other.

19. The luminous device according to claim 1 , wherein the luminous device is part of on a motor vehicle.

20. A luminous device, said device comprising:
a segmenting part including a plurality of through-cavities;
a plurality of light sources upstream of the segmenting part; and
a translucent mask that blocks at least one through-cavity of the segmenting part, said mask being able to be partially passed through by light,
wherein said luminous device is arranged so that each through-cavity directly or indirectly receives light from at least one separate light source.
