Method and apparatus for achieving uniform high locality light

摘要

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.

1. An apparatus for controlling light propagation, comprising:
a muntin including reflective walls arranged to form a plurality of openings, the muntin being configured to assemble with an array of light sources; and a cavity sheet resting on the reflective walls, wherein the cavity sheet has a plurality of pinholes having curved sidewalls in a cross-sectional view, the cavity sheet being configured to assemble with the muntin such that the reflective walls align with areas between the pinholes, wherein the curved sidewalls form a parabolic reflector and an opening is located at a vertex of the parabolic reflector.
