1. A light diffusion system, comprising:
a light-pipe structure having a length, an upper surface and a lower surface forming an angle with the upper surface such that an emitter surface of the light-pipe structure tapers from a relatively thicker central portion to relatively thinner terminal portions at each end of the length;
a light diffuser having a first portion and a second portion optically coupled to and disposed orthogonal to the first portion;
wherein the first portion of the light diffuser disposed proximate the emitter surface of the light-pipe structure such that, in operation, at least a portion of the light conveyed by the light pipe structure exits radially outward from the second portion of the light diffuser; and
wherein the light diffuser comprises a light diffuser in which the first portion and the second portion optically couple to provide a light diffuser having a “T”-shaped transverse cross-section.
