Abstract
A system for illuminating an environment, includes a first and second angularly varying light emitting devices operable to adjust light flux output into different angular bins individually, the second angularly varying light emitting device further comprises an imager positioned to receive light reflected from the environment from the first and second angularly varying light emitting devices, wherein when the first angularly varying light emitting device emits first light flux onto on object or individual in the environment and the object or individual occludes the first light flux creating a shadow region on a surface of the environment, the second angularly varying light emitting device emits second light flux from one or more second light sources into an angular bin that illuminates the shadow region. In one embodiment, the shadow region is identified in part by differentiating between a possible dark surface and a region comprising a shadow.
