Abstract

A light guide includes a light guide layer having a transversely oriented side-end surface that forms a primary output aperture (exit) for light traveling in a forward propagation direction out of the end surface of the light guide (for, e.g., CPV applications) and, which forms a primary input aperture (entrance) for light traveling in a rearward propagation direction into the end surface of the light guide (for, e.g., illuminator applications). A light collection and concentration system includes a light guide apparatus, a light-transmitting medium layer disposed immediately adjacent the single light guide apparatus, and a light concentrator component of multiple optical array layers disposed adjacent the light transmitting medium layer, which is in optical registration with a light injection layer of the light guide apparatus.
