Abstract: The disclosure generally relates to efficient hollow light duct bends (200) that are capable of retaining a higher on-axis transmission for partially collimated light propagating within a light duct (220, 230). In particular, the described hollow light duct bends (200) include input and output plates (214, 216) that have low reflectivity for near nonnal incident light, and high reflectivity for near grazing incident light.

Abstract: The present disclosure provides a novel construction for an illuminated light splitter in a mirror-lined light duct. In particular, the present disclosure addresses the ability to split partially collimated light travelling through a light duct into two different light ducts using light diverters, while extracting a portion of the light from each of the light ducts and also from the common intersection region. In some cases, the visual appearance of the illumination in the intersection region can appear non-uniform due to the presence of the light diverters, and the present disclosure provides an illuminated light duct splitter (100, 200, 300) configuration that homogenizes the output from the illuminated duct within the intersection region (117, 217, 317).

Abstract: 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.

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 bollard luminaire includes a design that generally confines light to illuminate the cross-walk 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 The delivery and distribution system (i.e., light duct and light duct extractor) can function effectively with any light source that is capable of delivering light which is substantially collimated about the longitudinal axis of the light duct, and which is also preferably substantially uniform over the inlet of the light duct.

Abstract: An OLED display including a display panel and a color-correction component is described. A plurality of comparative display panels otherwise equivalent to the display panel but having one or more different optical thicknesses of OLED layers have a maximum white-point color shift from 0 to 45 degrees of WPCSC45 and a white-point axial efficiency of WPAEC. The plurality of comparative display panels defines a performance curve along a boundary of performance points. The OLED display and the display panel have respective maximum white-point color shifts from 0 to 45 degrees of WPCS45 and WPCS045 and respective white-point axial efficiencies of WPAE and WPAE0. WPCS045 and WPAE0 defines a performance point of the display panel to the right of the performance curve and WPCS45 and WPAE defines a performance point of the OLED display above or to the left of the performance curve. Methods of making the OLED display are described.
