Abstract
A light guide apparatus includes a light guide layer further including light injection elements and respective light bypass elements disposed optically upstream of the light injection elements. The light injection elements and/or the bypass elements can take the form of injection facets (air prisms), surface diffraction elements, volume diffraction elements, and gradient index profiles. A light collection and concentration system comprises a single light guide apparatus, a light-transmitting medium layer disposed immediately adjacent the single light guide apparatus, and a primary light concentrator component disposed adjacent the light-transmitting medium layer, including a plurality of primary concentrator elements each of which is in optical registration with a respective one of the light injection elements of the single light guide apparatus.
