Abstract

An edge-lit rearview assembly comprising a housing; a mirror element having a perimeter and disposed within the housing; a bezel extending around at least a portion of the perimeter of the mirror element; at least one circuit board; at least one light source in electrical communication with the circuit board; wherein the at least one light source is in optical communication with at least a portion of the bezel.

Claims

1. An edge-lit rearview assembly for a vehicle comprising:

a display element having a perimeter;

a bezel extending around at least a portion of the perimeter of the display element;

a first circuit board;

at least one light source in electrical communication with the first circuit board; and

at least one light pipe in optical communication with the at least one light source and having a first end and a second end;

wherein the bezel defines a channel;

wherein the bezel and associated channel extend along at least a portion of the perimeter of the display element;

wherein the at least one light pipe is at least partially disposed within the channel; and

wherein the at least one light source is configured to illuminate at least a portion of the bezel.

2. The edge-lit rearview assembly of claim 1, wherein the rearview assembly is a frameless rearview assembly and wherein the display element is a mirror element.

3. The edge-lit rearview assembly of claim 1, wherein the first end of the at least one light pipe is in optical communication with the at least one light source and wherein at least a portion of the at least one light pipe is in optical communication with at least a portion of the bezel.

4. The edge-lit rearview assembly of claim 3, wherein the at least one light pipe has a longitudinal surface;

and wherein at least a portion of the longitudinal surface has one of a textured surface and a reflective coating on the surface.

5. The edge-lit rearview assembly of claim 3, wherein the second end of the at least one light pipe is in optical communication with at least a second light source.

6. The edge-lit rearview assembly of claim 3, further comprising at least one auxiliary light pipe, each of the at least one auxiliary light pipes having a first end and a second end;

wherein the first end of each of the at least one auxiliary light pipes is in optical communication with the at least one light source; and

wherein the second end of each of the at least one auxiliary light pipes is in optical communication with one of the at least one light pipes.

7. The edge-lit rearview assembly of claim 6, further comprising at least a second circuit board and a main circuit board;

wherein the main circuit board is in electrical communication with the at least first and second circuit boards.

8. The edge-lit rearview assembly of claim 3, wherein the second end of the at least one light pipe comprises a reflective surface configured to reflect light toward the first end of the at least one light pipe.

9. The edge-lit rearview assembly of claim 3, further comprising at least a second light pipe having a first end and a second end;

wherein the first end of the at least second light pipe is in optical communication with at least a second light source and with the bezel.

10. The edge-lit rearview assembly of claim 1, wherein the bezel and associated channel extend along at least a portion of the perimeter of the display element.

11. The edge-lit rearview assembly of claim 1, wherein the bezel is one of transparent or translucent.

12. The edge-lit rearview assembly of claim 7, further comprising at least one other vehicle system or computer;

wherein the at least one other vehicle system or computer is in electrical communication with and provides inputs to at least one of the first and second circuit boards to allow the at least one of the first and second circuit boards to selectively activate at least one light source based on the received inputs.

13. The edge-lit rearview assembly of claim 1, further comprising at least one baffle disposed within the bezel;

wherein the at least one baffle optically separates the bezel into a plurality of separate lighting zones; and

wherein at least one lighting zone is in optical communication with at least one light source.

14. The edge-lit rearview assembly of claim 1;

wherein the bezel is segmented into different portions by at least one physical break between each portion;

wherein the at least one physical break optically separates the bezel into a plurality of separate lighting zones; and

wherein the at least one lighting zone is in optical communication with at least one light source.

15. An edge-lit rearview assembly comprising:

a housing;

a display element having a perimeter and supported by the housing;

a bezel extending around at least a portion of the perimeter of the display element;

at least one circuit board;

at least one light source in electrical communication with the circuit board; and

at least one light pipe having a first end and a second end in optical communication with the at least one light source;

wherein the bezel defines a channel; and

wherein the at least one light pipe is at least partially disposed within the channel.

16. The edge-lit rearview assembly of claim 15, further comprising at least one vehicle system;

wherein the edge-lit rearview assembly is in communication with and receives inputs from the at least one vehicle system;

wherein the at least one circuit board is configured to selectively activate at least one light source in response to the inputs; and

wherein activating at least one light source causes at least a portion of the bezel to be illuminated.

17. The edge-lit rearview assembly of claim 15, further comprising at least one baffle disposed within the bezel;

wherein the at least one baffle optically separates the bezel into a plurality of separate lighting zones; and

wherein at least one lighting zone is in optical communication with at least one light source.

18. The edge-lit rearview assembly of claim 15, wherein the bezel and associated channel extend at least partially around the perimeter of the display element.
