Patent ID: 8668370

Claim:
A light distribution apparatus comprising: (a) a light distribution plate comprising: (i) a layer of optically transparent material, the layer of optically transparent material comprising an upper surface; a lower surface disposed opposite the upper surface; and an edge surface that bridges the upper and lower surfaces along their perimeter; wherein the upper surface defines a plurality of inverted, right circular cone-shaped indentations that extend toward the lower surface; and (ii) a coating of optically reflective material disposed on at least those portions of the upper surface that define the interior surfaces of inverted, right circular cone-shaped indentations; and (b) one or more near point light sources configured to direct light into the edge surface of the layer of optically transparent material; wherein the light distribution plate is configured such that light directed into the edge surface of the layer of optically transparent material by the one or more near point light sources and reflected from the coating of optically reflective material on the interior surfaces of the plurality of inverted, right circular cone-shaped indentations will be projected onto the lower surface of the layer of optically transparent material with a pixelated spatial intensity distribution.
