摘要： LED lighting apparatus including (a) a circuit board which has a plurality of light sources spaced thereon, (b) a heat sink to which the circuit board is thermally coupled, and (c) a securement structure which includes a rigid peripheral structure applying force along a peripheral area of the circuit board toward the heat sink to increase the thermal coupling therebetween to facilitate heat transfer from the light sources during operation. The lighting apparatus may also include an optical member with a plurality of lens portions over corresponding light sources and a peripheral region, the securement structure engaging the peripheral region which sandwiches a gasket against the heat sink. The apparatus may use manipulation involving surface convexity, such as bowing, thereby allowing the securement structure to further facilitate surface-to-surface thermal coupling between the circuit board and the heat sink.

摘要： A lens (10) for distribution of light from a light emitter (1) having an emitter axis (2). The lens includes an inner surface defining an inner cavity (20) and including a substantially cross-sectionally convex inner region (22A-D) along an open end of the inner cavity and a substantially cross-sectionally linear inner region joining the substantially cross-sectionally convex inner region and extending therefrom toward the emitter axis. The convex region is configured for refracting emitter light rays toward the emitter axis. The lens further includes an outer surface receiving the light from each of the inner regions. A lens flange (60A-D) surrounds the lens and extends radially outwardly from the lens outer surface at positions axially spaced from the light emitter. Each lens has at least one layer of a polymeric material extending into the lens flange of such material and is spaced from the lens flanges that surround the adjacent lenses.

摘要： Fluorescent lighting systems (1) are described. In an embodiment first and second type reflector panels (140, 40) are provided with the first type reflector panel (140) having a greater translucency compared to the second type reflector panel (40). Each of the reflector panels is structured for being secured in the lighting system. The use of different type reflector panels provides an opportunity for control of uplight and downlight from the lighting system.
