Abstract:
1. A light pipe array lens comprising: a monolithic block having first and second surfaces, the monolithic block being made of a first material, the monolithic block including a plurality of parallel cuts within the monolithic block that extend from the first surface of the monolithic block to the second surface of the monolithic block; and a two-dimensional array of light pipes disposed in the monolithic block such that the light pipes extend from the first surface to the second surface, the light pipes being made of the same first material as the monolithic block, each of the light pipes being enclosed by walls made of a second material having an index of refraction lower than an index of refraction of the first material, wherein the walls are disposed in the plurality of the parallel cuts of the monolithic block and wherein the walls are formed in the parallel cuts of the monolithic block with the second material to define the light pipes that are enclosed by the walls.
