Abstract
An apparatus for concentrating solar radiation includes a number of modules. Each module has three receivers for receiving reflected radiation and a reflecting surface. The receivers form a triangle in a plane approximately parallel to the reflecting surface. The reflecting surface has a number of reflectors. Each of the reflectors includes three mirrored facets which are each oriented such that light reflected from the facet is directed to one of the three receivers. Further, each of the reflectors is positioned with respect to the receivers and the other reflectors to reduce facet shading.

An apparatus for reducing facet shading, comprising a substrate including three points that form a triangle and including a plurality of reflecting regions interior to the three points, each region including three reflecting facets, where each facet is oriented such that light reflected from the facet is directed to one of the three points and is positioned to reduce facet shading from any other reflecting facet in the region or any other region.
An apparatus for generating radiation, comprising three sources for producing radiation, wherein the sources form a triangle in a plane approximately parallel to a reflecting surface and the reflecting surface which includes a plurality of reflectors, wherein each of the reflectors includes three mirrored facets which are each oriented such that light is directed from one of the three sources and wherein each of the reflectors is positioned with respect to the sources and the other reflectors to reduce facet shading.
An apparatus for generating light, comprising a plurality of modules, each module including three sources for generating light and a reflecting surface, wherein the sources form a triangle in a plane approximately parallel to the reflecting surface, and wherein the reflecting surface includes a plurality of reflectors, each of the reflectors including three mirrored facets which are each oriented such that reflected light is directed from one of the three sources and wherein each of the reflectors is positioned with respect to the sources and the other reflectors to reduce facet shading.
