    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: A lamp comprises an enclosure that is at least partially optically transmissive. The enclosure comprises an optically transmissive lens and a base where the lens is connected to the base; and a LED board supporting an LED. A first of pins and a second pair of pins are rotatable relative to the enclosure and are in the electrical path supplying power to the LEDs. The lamp is positioned between a pair of tombstone connectors such that the first pair of pins engages the first tombstone connector and the second pair of pins engages the second tombstone connector. The first and second pair of pins are inserted into the tombstone connectors and are rotated to engage the electrical connectors in the tombstone connectors.

    Abstract: A LED lamp has an enclosure including an optically transmissive lens. LEDs are mounted on a plane in the enclosure and are operable to emit light through the lens when energized through an electrical path. A portion of the lens extends behind the plane of the plurality of LEDs such that a portion of the light is emitted as back light. Approximately between 5 and 25 percent of the total Lumen output of the lamp is emitted as backlight.

    Abstract: According to one aspect, a luminaire comprises a waveguide body including a central section and first and second separate side sections extending away from the central section along first and second opposed directions, respectively. The central section includes a coupling portion and the waveguide body has a length and includes a plurality of light extraction features that extract light out of the side sections. At least one LED is disposed adjacent the coupling portion and is operated by a power circuit to produce light that is directed into the waveguide body by the coupling portion. At least one structural member extends along the length of the waveguide body for supporting the waveguide body and encloses at least one of the power circuit and the at least one LED.
