Abstract: A light fixture with a textured reflector surface is disclosed. Embodiments of the present invention provide for a lighting system in which LEDs face, and the majority of light form the LED light source is incident on, a textured surface of a back reflector while producing minimal glare and minimal imaging of the light source. Such a reflector may be referred to as a retro-reflector. The reflector for the light fixture can be made from a relatively inexpensive material such as polycarbonate, which without texturing has a specular or semi-specular surface. This material can be used alone or with a metal substrate to form the reflector. The textured surface can be textured by way of an imprinted pattern or by roughening, and can be extruded. A prismatic texture may be used. The texturing can also be spatially varied.

Abstract: In one aspect, luminaires are described herein enabling independent thermal management of driver and LED assemblies. For example, a luminaire comprises a driver assembly vertically integrated with a LED assembly, the driver assembly comprising a driver heatsink having an interior in which a circuit board assembly is positioned, and the LED assembly comprising an array of LEDs and LED heatsink, wherein a barrier is positioned between the driver heatsink and the LED heatsink, separating convective cooling of the driver assembly from convective cooling of the LED assembly.

Abstract: The fixture includes an elongated back reflector along the longitudinal direction of the fixture and at least one light source mounted to a heat sink structure and arranged to emit at least a portion of light toward the back reflector. The back reflector redirects at least a portion of the light toward an exit lens which interacts with the light as it is emitted from the fixture. Both the shape of the individual fixture elements (e.g., the back reflector and the exit lens) and the arrangement of these elements provide an asymmetrical light output distribution. Various mount mechanisms may be used to attach the fixture to a surface such as a ceiling or a wall, or the fixture may be suspended from a in a pendant configuration.

Abstract: A linear solid state lighting fixture with asymmetric distribution. The fixture comprises an elongated back reflector along the longitudinal direction of the fixture. At least one light source is arranged to emit toward the back reflector. The source(s) are mounted to a heat sink structure such that at least a portion of light emitted from the source(s) first impinges on the back reflector which redirects at least a portion of the light toward an exit lens. The exit lens interacts with the light as it is emitted from the fixture. Both the shape of the individual fixture elements (e.g., the back reflector and the exit lens) and the arrangement of these elements provide an asymmetrical light output distribution. Various mount mechanisms may be used to attach the fixture to a surface such as a ceiling or a wall, or the fixture may be suspended from a in a pendant configuration.
