Abstract

A vehicle lighting system is provided. The system includes a sun visor having a visor body movable between a stored position and a use position. A photoluminescent structure is coupled to a surface of the visor body and a light source is coupled to a headliner and oriented to excite the photoluminescent structure when the visor body is in the use position. A switch is included for activating the light source in response to a signal change.

Claims

1. A vehicle lighting system comprising:

a sun visor having a visor body movable between a stored position and a use position;

a photoluminescent structure coupled to a surface of the visor body;

a light source coupled to a headliner and oriented to excite the photoluminescent structure when the visor body is in the use position; and

a switch for activating the light source in response to a signal change.

2. The system of claim 1, wherein the light source is sunken into the headliner.

3. The system of claim 1, wherein the light source is at least one of a blue LED and an ultraviolet LED.

4. The system of claim 3, wherein the photoluminescent structure contains a photoluminescent material formulated to convert light received from the light source into visible light of a different color.

5. The system of claim 1, wherein the switch comprises a magnetic switch embedded in a headliner and is actuated by a magnet embedded in the visor body.

6. The system of claim 5, wherein the magnetic switch comprises a first contact and a second contact, wherein the first and second contacts are open when a magnetic field is present and closed when the magnetic field is no longer present.

7. A vehicle lighting system comprising:

a sun visor having a visor body movable between a stored and a use position;

a photoluminescent structure coupled to a surface of the visor body; and

a light source remotely located from the visor body and oriented to excite the photoluminescent structure when the visor body is in the use position.

8. The system of claim 7, further comprising a proximity sensor for activating the light source in response to a signal change.

9. The system of claim 8, wherein the proximity sensor comprises a magnetic switch embedded in a headliner and is actuated by a magnet embedded in the visor body.

10. The system of claim 9, wherein the magnetic switch comprises a first contact and a second contact, wherein the first and second contacts are open when a magnetic field is present and closed when the magnetic field is no longer present.

11. The system of claim 7, wherein the light source is coupled to a headliner.

12. The system of claim 7, wherein the light source is at least one of a blue LED and an ultraviolet LED.

13. The system of claim 12, wherein the photoluminescent structure contains a photoluminescent material formulated to convert light received from the light source into visible light of a different color.

14. A vehicle lighting system comprising:

a sun visor having a visor body movable between a stored and a use position;

a photoluminescent structure coupled to a surface of the visor body; and

a light source for exciting the photoluminescent structure when the visor body is in the use position.

15. The system of claim 14, wherein the light source is coupled to a headliner.

16. The system of claim 14, further comprising a proximity sensor for activating the light source in response to a signal change.

17. The system of claim 16, wherein the proximity sensor comprises a magnetic switch embedded in a headliner and is and is actuated by a magnet embedded in the visor body.

18. The system of claim 17, wherein the magnetic switch comprises a first contact and a second contact, wherein the first and second contacts are open when a magnetic field is present and closed when the magnetic field is no longer present.

19. The system of claim 14, wherein the light source is at least one of a blue LED and an ultraviolet LED.

20. The system of claim 19, wherein the photoluminescent structure contains a photoluminescent material formulated to convert light received from the light source into visible light of a different color.
