Abstract: In an embodiment, the disclosure provides a light source comprising at least one solid state light emitter. The light source, in operation, emits substantially white light having a Lighting Preference Index (LPI) of at least about 105, and this emission from the light source comprises a UV-violet flux of at least about 1%. Use of the lamps, light sources, and methods of the present disclosure may afford the ability to display linens and clothing under energy-efficient LED-based illumination, and may impart an effect to (especially white) clothing, that makes them look cleaner than under illumination by prior art LED lamps.

Abstract: Suspended lighting fixtures are described that include one or more light sources and a lens component that minimizes and/or eliminates unwanted shadows caused by debris such as dust and/or insects. In some embodiments, the suspended light fixture includes a housing, at least one light source operably connected to the housing, and a lens element operably connected to the housing. The lens element includes a tip portion and a debris hiding feature, wherein the debris hiding feature at least minimizes undesirable shadows that occur when light emitted from the at least one light source impinges on the debris that settled on an interior of the tip portion.

Abstract: The specification and drawings present a new light accessory holder, comprising only one part, for placing and interchanging multiple optical accessories in a lighting fixture near/in front of a light sources such as LEDs. The holder can use multiple notched springs (e.g., three) to push accessories forward and holds them in a desired position. The may be removed from the lighting fixture, so the user can load into the holder whatever accessories are needed, and then return the re-loaded holder into the light fixture. Accessories may include but are not limited to diffusers, glass components (optical filers), Hexcel Louvers, snoots, or other objects that are intended to alter the color or shape of a light source.

Abstract: Methods and systems are disclosed for generating a polygon mesh that may have concavities and/or holes. One example of such a method includes generating a polygon grid, adjusting the grid to fit input image dimensions, adjusting the polygons within the grid to fit detected pixels of interest, simplifying the resulting polygon collection to reduce the total number of polygons, and generating a polygon mesh based on the simplified collection of polygons.

Abstract: A system and method according to various embodiments can include a lighting fixture comprising a light source. A multilayer thin film coated reflector is applied to an outer light emitting surface of the lighting fixture. A top layer of the multilayer thin film coated reflector comprises a material including an anatase TiO crystal structure that exhibits antimicrobial properties when activated by the light source.

Abstract: The present disclosure describes embodiments of an optical system for use in a lighting device, e.g., replacements for MR/PAR/R directional lamps. In one embodiment, the optical system comprises optical elements (e.g., a lens element) with features that form light from a light source into a light beam. In one embodiment, the optical elements have a plurality of focus points, which do not all converge to a single focus point proximate the light source. Rather one or more of the focus points are spaced apart from the light source so the collective configuration of focus points causes the light beam to exhibit favorable characteristics.

Abstract: A lighting system that includes a light source that generates electromagnetic radiation including visible light and ultraviolet radiation, and a molded component formed of an optically translucent or transparent acrylate-fluoro copolymer or blend containing a fluoropolymer and an acrylate polymer. The acrylate polymer has a visible light total transmissivity that is lower than the visible light total transmissivity of the fluoropolymer, and each of the fluoropolymer and the acrylate-fluoro copolymer or blend has a limiting oxygen index that is higher than a limiting oxygen index of the acrylate polymer.

Abstract: Thermal management techniques and methods for various types of structures that require a thermal property, such as thermal conductivity and/or flame retardance, and have a surface in proximity to a source of thermal energy. Such a structure includes a substrate formed of a metallic material or a thermally conductive plastic material, and a white fluoropolymer layer directly on a surface of the substrate without a discrete adhesive layer therebetween. The white fluoropolymer layer defines an outermost surface of the structure, has a reflectivity of greater than 95%, and has a thickness sufficient to inhibit degradation of the thermal property of the structure resulting from impingement of the surface by the thermal energy.
