Abstract
A light wedge (300) formed from light conducting material comprises a first surface (308) for receiving light rays from a light emitting source (515), the first surface (308) having a first axial length, and a second surface (310) substantially opposite the first surface (308) and having a second axial length. The light wedge (300) additionally comprises two side surfaces (315, 320) further bounding the light conducting material between the first surface (308) and the second surface (310) and a plurality of sidewalls (325, 330, 333) positioned about an axis substantially parallel to a line of symmetry between the two side surfaces (315, 320), the plurality of sidewalls (325, 330, 333) forming a cavity within the light conducting material, wherein the plurality of sidewalls (325, 330, 333) receives and distributes a first portion of the light rays through the light conducting material.
