摘要： A self-sanitizing surface structure configured to selectively refract light, a method of fabricating a self-sanitizing surface configured to selectively refract light, and a method of decontaminating a surface using selectively refracted light. A waveguide including a support layer below a propagating layer is positioned over a substrate as a self-sanitizing layer. In the absence of a contaminant or residue on the waveguide, UV light injected into the propagating layer is constrained within the propagating layer due to total internal reflection. When a residue is present on the self-sanitizing surface structure, light may be selectively refracted at or near the interface with the residue along the side of the waveguide to destroy the residue. The self-sanitizing surface structure may be configured to refract a suitable amount of UV light in response to a particular type of residue or application.

摘要： An optical device includes a stack that includes a first curved optical element stacked with a second curved optical element. The second curved optical element propagates light by total internal reflection. The stack also includes an incoupling diffractive grating that incouples the light into the second optical element and an outcoupling diffractive grating optically coupled to the incoupling diffractive grating through the second curved optical element. The outcoupling diffractive grating directs the light. The first curved optical element has a first refractive index, the second curved optical element has a second refractive index, and the first refractive index is different from the second refractive index by approximately 0.15 to 1.2.

摘要： A lighting unit which includes a multilayer body and at least a first light emitting diode (LED) light source. The multilayer body includes, in sequence, a carrier layer of a black or gray translucent thermoplastic composition, a stone layer with an average thickness of 2 mm of less, and a transparent thermoplastic layer with an average thickness of 1 mm to 6 mm. The LED light source is disposed facing at least one lateral edge of the transparent thermoplastic layer, such that light from the LED light source is guided within the transparent thermoplastic layer.

摘要： In one embodiment, a film-based lightguide comprises a plurality interior light directing edges in a tapered light mixing region with curved sections which redirect light within the tapered light mixing region of the film. The interior light directing edges may be formed by cuts in the film that create an air gap between internal edges of the film. In one embodiment, the difference between radii of curvature of neighboring radii of arc sections of interior light directing edges is within 20% of an average distance between the arc sections. In one embodiment, the interior light directing edges totally internally reflect light propagating through the tapered light mixing region such that the light propagates at a smaller angle to a direction orthogonal to a width direction and orthogonal to the thickness direction of the film.

摘要： A luminaire module includes light-emitting elements (LEEs) arranged to provide light; a light guide including a receiving end and an opposing end, the receiving end arranged to receive light provided by the LEEs, a core including a first transparent material with a first refractive index, the core having a pair of opposing side surfaces extending along a length of the light guide between the receiving and opposing ends, and a cladding including a second material having a second smaller refractive index, the cladding extending across and being in contact with at least a portion of the opposing side surfaces forming a cladding-core interface. The cladding-core interface is optically smooth. Additionally, the luminaire module includes an optical extractor arranged to receive guided light from the opposing end of the light guide and configured to output into the ambient environment at least some of the received guided light.
