Abstract: In one aspect, an illumination source includes a socket formed by the union of a sub-assembly 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.

Abstract: An illumination system in accordance with an embodiment hereof includes a first substantially flat waveguide for propagating and emitting light. The first waveguide may include a plurality of optical elements increasing in density from an edge to the center of the first waveguide. Light enters the first waveguide at the edge, and light is emitted from the top surface of the first waveguide. The intensity of the emitted light is substantially uniform over the top surface.

Abstract: A sub-assembly matable to a waveguide having a recess therein includes a structure comprising a discrete light source disposed on a carrier, and a substrate and a heat spreader disposed beneath the structure. The structure has a contour complementary to the recess, such that, when the sub-assembly is joined to the waveguide, the discrete light source is within the waveguide.

Abstract: In one aspect, 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.

Abstract: In one aspect, a planar illumination area includes two light-guide elements, each with an out-coupling region. At least a portion of each out-coupling region overlaps with at least a portion of the other. The overlapping region emits a substantially uniform light output power.

Abstract: Illumination surfaces according to the present invention eliminate or at least reduce linear “stitch” artifacts at edges between tiled illumination devices. As a result, light of substantially uniform intensity is emitted across the entire illumination system. This is achieved, in various embodiments, overlapping the illumination surfaces of adjacent light-guide elements.
