Patent attributes
A linear wide area lighting system includes an elongated substrate having a linear light emitter array disposed on the substrate. The array includes a plurality of light emitters such as light emitting diodes or lamps. An elongated refractive lens is positioned over the substrate and linear light emitter array such that light emitted from the emitters is incident on the refractive lens and is refracted through the lens into a wide illumination area. The lens is extruded in some embodiments providing the lens with a substantially uniform extruded cross-sectional profile in some embodiments. The substrate is housed either between a base and the lens in some embodiments, or in an integrally formed bore in the lens body in other embodiments. One or more end caps are located on the longitudinal ends of the lens and base to fully enclose and seal the substrate and linear light emitter array.
