摘要： A solid state area light and spotlight having a solid state light source such as LEDs, tapered light guides, and external thermal guides. The area light includes a flared light guide, and the spotlight includes a light guide with a closed end. The light guides are coupled to the light source for receiving and distributing light from the light source with the distribution being based in part upon the shape and taper of the light guides. The thermal guide provides for thermal conduction from the light source and dissipating heat through convection and radiation for cooling the light.

摘要： A light duct elbow having two light conduits capable of transporting light along two different propagation directions. A light diverter is located between the light conduits and has a reflector for directing light along the light conduits. In the light duct elbow, a light ray propagating within a collimation angle in the first light conduit that intersects the reflector is diverted to a second light ray propagating within the collimation angle in the second light conduit.

摘要： A film stack reflects incident light in some areas and transmits incident light in other areas, and it redirects incident light with one or more structured surfaces. The spatially variable reflection and transmission is achieved at least in part with reflective strips, and the reflective strips are attached to a first major surface of a structured optical film in the film stack. A second major surface of the structured optical film, opposite the first major surface, attaches to a substrate. The reflective strips attach to the structured optical film by a first discontinuous adhesive layer, having first adhesive areas. The structured optical film attaches to the substrate by a second discontinuous adhesive layer, having second adhesive areas. A major portion of the first adhesive areas, and a major portion of the second adhesive areas, is circumscribed by the reflective strips. The film stack may be part of a light duct.

摘要： The present disclosure describes light delivery and distribution components of a light duct that can be used as a luminaire, such as a bollard-style luminaire that can be useful for the illumination of pedestrian crosswalks, the light engine useful in the luminaire, and methods for making the light engine and the luminaire. The present disclosure further describes methods for crosswalk illumination using the bollard-style luminaires, and methods of communication between bollard luminaires. The bollard luminaire includes a design that generally confines light to illuminate the crosswalk and the pedestrian in the crosswalk, such that light that could produce glare for the pedestrian and/or a driver approaching the crosswalk is minimized.

摘要： A light engine having an array of light horns. Each light horn has a narrow end, an open wide end, and side walls extending from the narrow end to the wide end with the side walls shaped as truncated pyramids. One or more LEDs are located at the narrow end of each of the light horns with each of the light horns providing substantially collimated light from the LEDs at the wide end.

摘要： Films and articles are described comprising a microstructured surface having an array of peak structures and adjacent valleys. For improved cleanability, the valleys preferably have a maximum width ranging from 10 microns to 250 microns and the peak structures have a side wall angle greater than 10 degrees. The peak structures may comprise two or more facets such as in the case of a linear array of prisms or an array of cube-corners elements. The facets form continuous or semi-continuous surfaces in the same direction. The valleys typically lack intersecting walls. Also described are methods of making and methods of use. The microstructured surface of the article can be prepared by various microreplication techniques such as coating, injection molding, embossing, laser etching, extrusion, casting and curing a polymerizable resin; and bonding microstructured film to a surface or article with an adhesive.

摘要： Generally, the present disclosure provides for a light engine, in particular a rack-mounted light engine that can be used in a lighting system. The rack mounted light engine can be positioned in an electronics component rack such a light distribution system using hollow light ducts may distribute the light over a large area, such as a data center. Such a light distribution can use a generated light more efficiently by directing the light to the fronts or backs of the electronics cabinet, rather than for general room illumination.
