Abstract

A light pipe array assembly is disclosed which includes an opaque carrier having an elongated planar platform defining upper and lower horizontal surfaces and a longitudinal axis, a first set of light pipes supported on the upper surface of the platform and arranged perpendicular to the longitudinal axis of the platform, and a second set of light pipes supported on the lower surface of the platform and arranged perpendicular to the longitudinal axis of the platform in alignment with the first set of light pipes, wherein the first and second sets of light pipes are optically isolated from each other by the platform of the carrier.

First claim

What is claimed is:

1. A light pipe array assembly comprising:
a) a carrier having an elongated platform defining upper and lower horizontal surfaces and a longitudinal axis;
b) a first plurality of light pipes supported on the upper surface of the platform and arranged perpendicular to the longitudinal axis of the platform; and
c) a second plurality of light pipes supported on the lower surface of the platform and arranged perpendicular to the longitudinal axis of the platform in alignment with the first plurality of light pipes, wherein the first and second pluralities of light pipes are optically isolated from each other by the platform of the carrier.

2. A light pipe array assembly as recited in claim 1 , wherein the carrier is constructed from an opaque plastic material.

3. A light pipe array assembly as recited in claim 1 , wherein the carrier includes legs depending from the lower surface of the platform for mounting the light pipe array assembly to a supporting structure.

4. A light pipe array assembly as recited in claim 1 , wherein each light pipe is formed from a clear plastic material.

5. A light pipe array assembly as recited in claim 1 , wherein each light pipe includes a central body portion, a proximal end portion for communicating with a light source and a distal end portion for communicating with a visual display remote from the light source.

6. A light pipe array assembly as recited in claim 5 , wherein the proximal end portion of each light pipe in the first plurality of light pipes includes a horizontal light receiving surface for communicating with the light source.

7. A light pipe array assembly as recited in claim 5 , wherein the proximal end of each light pipe in the second plurality of light pipes includes a vertical light receiving surface for communicating with the light source.

8. A light pipe array assembly as recited in claim 5 , wherein the platform includes a plurality of spaced apart mounting apertures in the upper and lower surfaces thereof for receiving mounting posts depending from the central body portion of each light pipe.

9. A light pipe array assembly as recited in claim 8 , wherein the central body portion of each light pipe includes a pair of spaced apart mounting posts.

10. A light pipe array assembly as recited in claim 5 , wherein the platform includes a first planar level associated with the central body portion and proximal end portion of each light pipe and a second planar level associated with the distal end portion of each light pipe.

11. A light pipe array assembly as recited in claim 1 , wherein each light pipe extends between a pair of upstanding walls formed integral with the platform.

12. A light pipe array assembly mounted to a printed circuit board, comprising:
a) a carrier having an elongated platform defining upper and lower horizontal surfaces and a longitudinal axis, and including legs depending from the lower surface of the platform for mounting the light pipe array assembly to the printed circuit board;
b) a first plurality of light pipes supported on the upper surface of the platform and arranged perpendicular to the longitudinal axis of the platform for communicating with a first plurality of light sources on the printed circuit board; and
c) a second plurality of light pipes supported on the lower surface of the platform and arranged perpendicular to the longitudinal axis of the platform in alignment with the first plurality of light pipes for communicating with a second plurality of light sources on the printed circuit board.

13. A light pipe array assembly mounted to a printed circuit board as recited in claim 12 , wherein the carrier is constructed from an opaque plastic material.

14. A light pipe array assembly mounted to a printed circuit board as recited in claim 12 , wherein each light pipe includes a central body portion, a proximal end portion for communicating with a light source and a distal end portion for illumination remote from the light source.

15. A light pipe array assembly mounted to a printed circuit board as recited in claim 14 , wherein the platform includes a first planar level associated with the central body portion and proximal end portion of each light pipe and a second planar level associated with the distal end portion of each light pipe.

16. A light pipe array assembly mounted to a printed circuit board as recited in claim 14 , wherein the proximal end portion of each light pipe in the first plurality of light pipes includes a horizontal light receiving surface for communicating with a light source.

17. A light pipe array assembly mounted to a printed circuit board as recited in claim 16 , wherein the proximal end of each light pipe in the second plurality of light pipes includes a vertical light receiving surface for communicating with a light source.

18. A light pipe array assembly mounted to a printed circuit board as recited in claim 16 , wherein the platform includes a plurality of spaced apart mounting apertures in the upper and lower surfaces thereof for receiving mounting posts depending from the central body portion of each light pipe.

19. A light pipe array assembly mounted to a printed circuit board as recited in claim 18 , wherein the central body portion of each light pipe includes a pair of spaced apart mounting posts.

20. A light pipe array assembly mounted to a printed circuit board as recited in claim 12 , wherein each light pipe extends between a pair of upstanding walls formed integral with the platform.

21. A light pipe array assembly mounted to a printed circuit board in a blade server housing, comprising:
a) a carrier having an elongated planar platform defining upper and lower horizontal surfaces and a longitudinal axis, and including legs depending from the lower surface of the platform for mounting the light pipe array assembly to the printed circuit board;
b) a first plurality of light pipes supported on the upper surface of the platform and arranged perpendicular to the longitudinal axis of the platform to transport light from a first plurality of light sources on the printed circuit board to a first plurality of ports on a front display panel of the blade server housing; and
c) a second plurality of light pipes supported on the lower surface of the platform and arranged perpendicular to the longitudinal axis of the platform in alignment with the first plurality of light pipes to transport light from a second plurality of light sources on the printed circuit board to a second plurality of ports on the front display panel of the blade server housing.

22. A light pipe array assembly mounted to a printed circuit board in a blade server housing as recited in claim 21 , wherein the carrier is constructed from an opaque plastic material.

23. A light pipe array assembly mounted to a printed circuit board in a blade server housing as recited in claim 21 , wherein the platform includes a plurality of spaced apart mounting apertures in the upper and lower surfaces thereof for receiving mounting posts depending from the central body portion of each light pipe.
