Patent ID: 8686648

Claim:
A lighting fixture for providing a tailored light intensity distribution over a planar surface in a region or area intended to be occupied by a person, the fixture comprising: a light transmissive structure forming a volume, the structure having: a substantially contoured outer optical output surface; and an optical input surface; a reflector having a reflective surface at least substantially opposite to the substantially contoured outer optical output surface and positioned such that the reflector and the substantially contoured outer optical output surface form an optical structure including the volume of the light transmissive structure, the reflective surface of the reflector facing towards the optical structure; and a plurality of solid state light emitters for producing light of sufficient intensity for illuminating the planar surface, the light produced by the solid state light emitters being diffused within the volume of the light transmissive structure and producing diffused light emission through the contoured outer optical output surface of the light transmissive structure, wherein the light transmissive structure is contoured to distribute light having a distribution curve as a function of an angle from an axis, the axis having a 0Â° angle, and light intensity increasing toward 90Â° in either direction away from the axis.
