Abstract:
The present disclosure describes advanced lighting elements, in particular solid-state lighting elements, and luminaires that include an array of lighting elements. The lighting elements, and luminaires including the lighting elements can exhibit benefits that include high optical efficiency and therefore high luminous efficacy; extraordinary directional control and therefore extraordinary glare control and efficacy of delivered lumens; and exceptional mixing of individual-device emission providing exceptional suppression of punch-through and color breakup. In many cases, the architecture can be amenable to low-cost manufacturing in a modular format.
Abstract:
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.

Abstract:
Reflective sheets are described. In particular, flat reflective sheets including reflectors and substrates are described. The reflective sheets may have at least one edge not parallel to any other edge. The reflective sheets may also include at least one tab. Other films may be attached or adhered to either the reflector or the substrate.
Abstract:
Luminaire assemblies are described. In particular, luminaire assemblies that include a dimensionally stable housing and a hollow waveguiding core having a length and capable of transporting light along the length removably nested within the housing are described. Luminaire systems including two or more luminaire assemblies are also described.
