Abstract: In one aspect, an illumination apparatus includes a waveguide, embedded in which are a light-emitting source and a photoluminescent material. Output light is emitted from at least a portion of a first surface of the waveguide. The photoluminescent material includes nano-size phosphor particles and/or quantum dots.
Abstract: In one aspect, an illumination structure includes a substantially non-fiber waveguide, which itself includes a discrete in-coupling region for receiving light, a discrete propagation region for propagating light, and a discrete out-coupling region for emitting light.
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: An illumination apparatus, comprising at least one light emitting source embedded in a waveguide material is disclosed. The waveguide material is capable of propagating light generated by light emitting source(s), such that at least a portion of the light is diffused within the waveguide material and exits through at least a portion of its surface.
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: 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: In various embodiments, an illumination structure includes a discrete light source disposed proximate a bottom surface of a waveguide and below a depression in a top surface thereof. A top mirror may be disposed above the discrete light source to convert modes of light emitted from the discrete light source into trapped modes, thereby increasing the coupling efficiency of the illumination structure.
