Abstract: A lighting fixture includes a front end-portion having an edge defining a light opening and a back end-portion spaced from the opening which has a centerline. At least one LED emitter on the mounting board disposed at the back end-portion for directing light toward the opening, the emitter(s) being off-centerline in a first lateral direction. A lens for the emitter(s), the lens being configured for distribution of light from the emitter(s) primarily in a second lateral direction which is opposite the first lateral direction such that the light passes through the light opening at a portion of the edge that is off-centerline in the second lateral direction, thereby to widen the illumination angle from the fixture.

Abstract: An optical waveguide includes a body of optically transmissive material having a width substantially greater than an overall thickness thereof and including a first side, a second side opposite the first side, a central bore extending between the first and second sides and adapted to receive a light emitting diode, and extraction features on the second side. A light diverter extends into the central bore for diverting light into and generally along the width of the body of material. The extraction features direct light out of the first side and wherein at least one extraction feature has an extraction surface dimension transverse to the thickness that is between about 5% and about 75% the overall thickness of the body of material.

Abstract: An LED light fixture including a housing portion and a base together defining an open space therebetween permitting air/water-flow therethrough. The housing portion forms a chamber enclosing at least one driver. The base extends from the housing portion and supports at least one LED illuminator outside the chamber. The housing portion and the base may each be formed as part of a one piece with the open space along at least three sides of the base. Alternatively, the base may be a separate structure secured with respect to the housing. Such base may be a single-piece extrusion supporting a plurality of LED modules or comprise a plurality of extruded heat sinks. Each heat sink may support one or more LED modules.
