Abstract:
The specification and drawings present a new apparatus such as a halogen incandescent lamp is presented herein, the apparatus comprising a light source such as a light-generating element made of tungsten, configured to generate a visible light such as white light having chromaticity coordinates of the light source in a clear center in a color space, and a component such as light-transmissive envelope, enclosing the light source and comprising a coating with a compound comprising elements of neodymium and fluorine and configured to provide a desired light spectrum by filtering the generated visible light using the compound, where the desired light spectrum having chromaticity coordinates in the color space being shifted from the clear center below the black-body locus and outside of a four-step MacAdam ellipse of the light source to meet a predefined requirement for a modified spectrum lamp.
Abstract:
Heavily phosphor loaded LED packages having higher stability and a method for increasing the stability of heavily phosphor loaded LED packages. The silicone content of the packages is increased by decreasing the amount of one phosphor of the blend or by increasing the thickness of the silicone phosphor blend layer.
Abstract:
Provided is a system enhancing control of bacterial growth by combining antimicrobial additives and surface micro-structure patterns on outer surfaces of a device, such as a lighting fixture. The system physically decreases bio-adhesion between microbes and substrates applied to the outer surfaces. The system combines a surface micro-structured component with an antimicrobial component to generate a single component.
Abstract:
A system and method according to various embodiments can include a lighting fixture comprising a light source. An antimicrobial additive is added to an outer light emitting surface of the lighting fixture exposed to air. A sealing substrate is positioned between the antimicrobial additive and the light source to provide clean room capabilities when the lighting fixture is installed to seal a plenum.
Abstract:
A directional lamp assembly includes a light source, a reflector having a first portion and a second portion and operative to direct light emitted from the light source to a target area, a heat sink circumscribing the reflector and operative to dissipate heat produced by the light source and a light diffusing lens disposed over the light source and operative to transmit light to the target area. The second portion of the reflector is disposed radially outboard of the first portion and is integrally formed in combination with the heat sink.
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:
Heavily phosphor loaded LED packages having higher stability and a method for increasing the stability of heavily phosphor loaded LED packages. A silicone overlayer is provided on the phosphor silicone blend layer.
Abstract:
Provided is a method including determining a first incident angle at which light from a light source will impinge on a first thin-film reflective stack of a planned first reflector for a lighting system. The method also includes determining a second incident angle at which light from the light source will impinge on a second thin-film reflective stack of a planned second reflector for the lighting system. The method further includes designing, using a processor executing a software package, the first reflector, comprising tuning a reflective characteristic of the first thin-film reflective stack as a function of the first incident angle determined, and designing, using the processor executing the software package, the second reflector, comprising tuning a reflective characteristic of the second thin-film reflective stack as a function of the second incident angle determined.
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:
Provided is a multi-layer reflective coating for application to a lighting housing assembly, including a polymer substrate adjacent a polymer base coat layer applied to the lighting housing. Atop the polymer base coat layer is an aluminum adhesion layer, followed by a diffusive barrier layer, and a silver reflective layer. The aluminum adhesion layer promotes adhesion between the polymer base coat layer and the silver reflective layer. The diffusive barrier layer prevents aluminum and silver interaction, which could form a silver and aluminum alloy. A spectrum tunable layer is applied atop the silver reflective layer for spectrum tuning the silver reflective layer for maximum compatibility with a light emitting diode (LED) lighting source.
