Patent ID: 8128262

Claim:
A lighting fixture for providing a tailored light intensity distribution over a designated 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, the outer optical output surface having a textured or etched output surface; and a peripheral portion positioned adjacent to the contoured outer optical output surface, the peripheral portion having an optical input surface; a reflector having a diffusely reflective surface extending over at least a substantial portion of a surface of the light transmissive structure to form an optical structure including the volume of the light transmissive structure, the diffusely reflective surface facing outwardly towards the optical structure; and a plurality of solid state light emitters for producing light of sufficient intensity for illuminating the designated planar surface, the light produced by the solid state light emitters being diffused within the volume of the light transmissive structure and emitted 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 0° angle, and light intensity increasing toward 90° in either direction away from the axis.
