Abstract

A lighting device for a vehicle including at least one light source, at least one sensor configured to acquire information outside the vehicle based on infrared. A cover including a first portion covers the at least one light source and a second portion that is opaque to visible light and to infrared. The cover further includes a third portion that is opaque to visible light and transparent to infrared, substantially centered on said at least one sensor and integrated into the second portion.

First claim

The invention claimed is:

1. A lighting device for a vehicle comprising at least one light source, at least one sensor configured to acquire information outside the vehicle based on infrared, a housing closed by a cover, said cover comprising a first portion covering said at least one light source and a second portion that is opaque to visible light and to infrared, characterized in that said cover further comprises a third portion that is opaque to visible light and transparent to infrared, substantially centered on said at least one sensor and integrated into the second portion.

2. The lighting device as claimed in claim 1 , wherein said at least one sensor is a lidar.

3. The lighting device as claimed in claim 1 , wherein said lighting device comprises a plurality of light sources.

4. The lighting device as claimed in claim 1 , wherein said lighting device comprises a plurality of sensors.

5. The lighting device as claimed in claim 1 , wherein said cover is made of poly(methyl methacrylate) (PMMA) or of polycarbonate.

6. The lighting device as claimed in claim 1 , wherein said third portion comprises a transmission capacity for visible light that is lower than the first portion.

7. The lighting device as claimed in claim 1 , wherein said at least one light source is a semiconductor, halogen, xenon, or laser light source.

8. The lighting device as claimed in claim 1 , wherein said lighting device is a headlight or a tail light.

9. The lighting device as claimed in claim 1 , wherein said second portion and said third portion are covered by said first portion of said cover which is coated over them.

10. The lighting device as claimed in claim 1 , wherein said first portion, said second portion and said third portion of said cover are arranged edge to edge.

11. The lighting device as claimed in claim 1 , wherein said first portion, said second portion and said third portion of said cover are injected.

12. The lighting device as claimed in claim 11 , wherein said first portion, said second portion and said third portion are overmolded.

13. The lighting device as claimed in claim 11 , wherein said first portion, said second portion and said third portion are assembled together.

14. The lighting device as claimed in claim 11 , wherein two portions of said first portion, second portion and third portion are overmolded and the other portion of said first portion, second portion and third portion is assembled together with at least one of said two overmolded portions, or vice versa.

15. The lighting device as claimed in claim 2 , wherein said lighting device comprises a plurality of light sources.

16. The lighting device as claimed in claim 2 , wherein said lighting device comprises a plurality of sensors.

17. The lighting device as claimed in claim 2 , wherein said cover is made of poly(methyl methacrylate) (PMMA) or of polycarbonate (PC).

18. The lighting device as claimed in claim 2 , wherein said third portion comprises a transmission capacity for visible light that is lower than the first portion.

19. The lighting device as claimed in claim 2 , wherein said at least one light source is a semiconductor, halogen, xenon, or laser light source.

20. The lighting device as claimed in claim 2 , wherein said lighting device is a headlight or a tail light.
