International Classification:

F21V 3/04
F21V 5/04

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:

A lighting apparatus with uniform illumination distribution, according to various embodiments, can include a lens for area lighting. In one embodiment, the lens comprises a plurality of cross-sections identified by a thickness ratio defined at different angles. The thickness ratio is determined relative to the thickness of the cross-section defined at a center angle of the lens. In another embodiment, the lighting apparatus with uniform illumination distribution includes a lens having an inner surface and an outer surface. A profile of the inner surface and the outer surface is composed of a plurality of piecewise circular arcs defined with radii and circle centers. The lens is formed as a complex curve lens by joining the piecewise circular arcs of the inner surface and the outer surface.
