Patent ID: 7431489

Claim:
A light ficture comprising: a) at least one light emitting source; b) a light transmitting region comprising a first anisotropic scattering region comprising a first continuous phase material of refractive index n c1 and a first dispersed phase material of refractive index n d1 wherein |n c1 −n d1 |>0.001 and one or more of the first dispersed phase domains are ellipsoidal in shape disposed to receive light from the light emitting source and scatter light to provide illumination; c) a housing providing support for the source and light transmitting region; and d) a substantially planar first light output surface wherein the first dispersed phase domains are arranged substantially parallel to the first light output surface and the anisotropic light scattering region scatters a predetermined first portion of light from the light emitting source toward the first light output surface and a second predetermined portion of light away from the first light output surface.
