Abstract
A method and apparatus for effectively controlling light propagation are presented. The apparatus includes a muntin having reflective walls arranged to form a plurality of openings, and a cavity sheet disposed on the muntin. The muntin is configured to assemble with an array of light sources. The cavity sheet has a plurality of pinholes and is configured to assemble with the muntin such that the reflective walls align with areas between the pinholes. The light sources, the muntin, and the cavity sheet form light mixing cavities and light sources within each light mixing cavities may be individually controlled. The light mixing cavities allow generation of localized and uniform light.
