Abstract

An interior lighting arrangement for automotive use comprises an array of light emitting diodes (LEDs) encapsulated in a light diffusing material disposed in a frame with a lens overlying the light diffusing material, the array of LEDs and the frame. Preferably, the light diffusing material is translucent epoxy and the lens is grated to further diffuse and direct light. In accordance with one embodiment of the LED lighting arrangement, the lighting arrangement is in combination with a sun visor to illuminate a vanity mirror.

Claims

1. An interior lighting arrangement for automotive use comprising:

a frame defining an enclosed space and a light emitting area;

an array of light emitting diodes (LEDs) disposed in the enclosed space;

a light diffusing material encapsulating the LEDs in the enclosed space, and

a lens overlying the light diffusing material, LEDs and light emitting area defined by the frame.

2. The interior lighting arrangement of claim 1 wherein the light diffusing material is translucent epoxy.

3. The interior lighting arrangement of claim 2 wherein the lenses are configured as a light diffuser.

4. The interior lighting arrangement of claim 3 wherein the frame is configured as an enclosure which completely surrounds the epoxy except for the light emitting area, the light diffusing lens being attached to the enclosure at a periphery of the enclosure adjacent to the light emitting area.

5. The interior lighting arrangement of claim 4 in combination with a sun visor.

6. An interior lighting arrangement for automotive use comprising:

an interior light mount configured as a sun visor on which at least one interior light is mounted;

at least one frame on the sun visor;

the frame defining an enclosed space and a light emitting area facing away from the enclosed space and the sun visor;

an array of light emitting diodes (LEDs) disposed in the enclosed space;

a light defusing material encapsulating the LEDs in the enclosed space, and

a lens overlying the light defusing material, LEDs and light transmitting area.

7. The interior lighting arrangement of claim 6 wherein the light defusing material is translucent epoxy.

8. The interior lighting arrangement of claim 7 wherein the lens is configured as a light diffuser.

9. The interior lighting arrangement of claim 8 wherein the frame is configured as an enclosure which completely surrounds the epoxy except for the light emitting area, the light diffusing lens being attached to the enclosure at a periphery of the enclosure adjacent to the light emitting area.

10. The interior lighting arrangement of claim 9 wherein there are at least two frames on the sun visor, each frame having the array of LEDs and light defusing material therein and having the lens thereon.

11. The lighting arrangement of claim 11 wherein the sun visor has a mirror disposed between the pairs of lights.

12. The lighting arrangement of claim 11 wherein the lights are recessed within depressions in the upper surface of the sun visor.
