Abstract

A flexible light shield for a light pipe.

Claims (12)

1 . An assembly for directing light comprising:

(a) a light guide having a plurality of optical light pipes, each of which are constructed from an optically transmissive material, having a curved path to direct light from a plurality of light emitting elements supported by a circuit board to panel of a housing for said circuit board, said light guide including a lower portion supporting said plurality of optical light pipes, said light guide constructed from material having a first flexibility;

(b) a light shield, said light shield constructed from material having a second flexibility, where said second flexibility is greater than said first flexibility, said light shield including a plurality of fins, said light shield including a lower portion supporting said plurality of fins;

(c) said plurality of fins detachably engageable with said optical light pipes wherein each of said plurality of fins is positioned between adjacent ones of said plurality of optical light pipes in such a manner that said adjacent ones of said plurality of optical light pipes has a corresponding one of said plurality of fins therebetween, said lower portion supporting said plurality of optical light pipes is detachably engageable with said lower portion supporting said plurality of fins.

2 . The assembly of claim 1 wherein said optically transmissive material is polycarbonate.

3 . The assembly of claim 1 wherein said light emitting elements are light emitting diodes.

4 . The assembly of claim 1 wherein said curved path is substantially 90-degrees.

5 . The assembly of claim 1 wherein said curved path is curved in a two-dimensional plane and not in a three-dimensional plane.

6 . The assembly of claim 1 wherein said plurality of optical light pipes are arranged in a linear arrangement with respect to one another.

7 . The assembly of claim 6 wherein the spacing between each of said plurality of optical light pipes and a next adjacent light pipe are the same.

8 . The assembly of claim 1 wherein said light shield is silicon.

9 . The assembly of claim 1 wherein said optical light pipes is one more than said plurality of fins.
