ABSTRACT:
An optical light guide (30) comprises a base (32); a body (34) extending from the base along a longitudinal axis (36); and N light-emitting segments (38) extending laterally from the body (34), at least some of the N segments (38) being spaced a different distance from the base (32). The light guide (30) is constructed of a light-transmitting material, such as glass or acrylic, and can be clear or colored. In a preferred embodiment of the invention each of the segments (38) would extend a different distance from the base; however, the exact degree of separation would be dependent upon the curvature of surface with which the optic is to be utilized.
