摘要
A directional illumination apparatus comprises a catadioptric micro-optic array comprising a reflective surface comprising light reflecting facets and an output transmissive surface comprising refractive structures. An array of micro-LEDs is arranged between the reflective surface and output transmissive surface and arranged to illuminate the reflective surface. The light reflecting facets and refractive structures cooperate to provide a uniform output illumination across the output aperture of the array with collimated output. A thin and efficient illumination apparatus may be used for switching display backlighting or environmental illumination applications.
