Abstract
A radiant energy redirecting apparatus, method, and system. In one aspect, it comprises two radiant energy distribution surfaces, each surface comprised of a multiplicity of equivalently shaped linear distribution elements, where each surface acts to distribute radiant energy in orthogonal directions, and where each surface is comprised of refractive or total internal reflection elements, or a combination thereof, for the purpose of efficiently directing pseudo-collimated radiant energy into a generally rectangular-shaped output distribution in angle space.
