Abstract

A light-emitting surface includes a plurality of discrete, substantially flat light-emitting illumination devices arranged in a tiled configuration Each device has a light-emitting area and an unilluminated area, the light-emitting area of a first device occluding at least a portion of the unilluminated area of a second, adjacent device In another aspect, an illumination source includes a socket formed by the union of a subassembly platform and a light-guide element, and a discrete light source received in the socket In another aspect, the light-guide element includes a concentration region proximate an in-coupling region opposite an out-coupling region, the concentration region directing multidirectional light from the in-coupling region toward the out-coupling region An overlapping region emits a substantially uniform light output power
