摘要:
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.

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.
摘要:
The specification and drawings present a new apparatus such as a lighting fixture and a method for replacing a light engine such as a LED light engine in the lighting fixture by replacing one part carrying the light engine, where the heat sink (e.g., extruded elongated heat sink) can be split into two parts, a replaceable part (10a) carrying the light engine and a fixed part (10b). Both heat sink parts may be attached together with a clip (30a, 30b) to allow the unclipping and replacement of the removable part (10a) carrying the light engine. The geometry of the two heat sink parts can be designed in such a way that one part can be attached on top of the other, while providing a predefined alignment and continuous thermal conductivity between the two parts. A space between the two parts (10a, 10b) can be used to place the clip (30a, 30b).
摘要:
Provided is a reflective matte coating layer, a lighting fixture and a method that includes a metal layer including an inner surface and an outer surface, and a powder coating layer disposed on the outer surface of the metal layer, wherein an infrared (IR) gradient curing operation is performed on the inner surface of the metal layer, to form a reflective matte coating at an external surface of the lighting fixture.
摘要:
Methods and materials capable of controlling the type and relative amounts of reflectance (e.g., specular vs. diffusive reflection) in reflective coatings, especially for inclusion in a lighting fixture or other lighting source. A method of forming a reflective coating on a substrate includes applying to the substrate a precursor material that comprises a cross-linkable binder resin, a cross-linking agent, and scattering pigment particles. The pigment particles are predominantly at or near an outer surface of the applied precursor material. Thereafter, the applied precursor material undergoes a single or multistep cure to form the reflective coating by cross-linking the binder resin. The cure energy level and duration inhibit migration of the pigment particles and/or the binder resin in the applied precursor material so that the pigment particles remain predominantly at or near an outer surface of the reflective coating.
摘要:
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.
摘要:
A system and method according to various embodiments combines three separate technologies to form a unique lighting system with enhanced antimicrobial properties and air cleaning capabilities. The combination of the three technologies also produces a lighting system that extends the required maintenance period for lighting fixtures. The first technology is based on anatase type T1O2. The second and third technologies are based on the use of micro-sized surface structures to generate light scattering effects and, at the same time, reduce bacterial colonization and inhibit bacterial migration even during the absence of light or in dark environments.
