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:
Materials and optical components formed thereof that are suitable for use in a lighting apparatus to impart a color filtering effect to visible light. At least a portion of such an optical component is formed of a composite material comprising a polymeric matrix material and an inorganic particulate material that contributes a color filtering effect to visible light passing through the composite material, and the particulate material comprises a neodymium compound containing Nd3+ ions.
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.
