WIPO Patent Application WO/2012/078408
Kind Code:
A3
Abstract:
A troffer- style fixture. The fixture is particularly well -suited for use with solid state light sources. The troffer comprises a light engine unit (200) surrounded by a reflective pan (104). An elongated heat sink (202) comprises a mount surface for light sources. An elongated lens (206) is mounted on or above the heat sink. The mount surface is designed to accommodate the light emitters which may come on prefabricated a light strip. One or more reflectors (208) extend out away from the heat sink on the mount surface side. A lens plate (210) is mounted to proximate to the heat sink and extends out to the edge of the reflector (s). An interior cavity is at least partially defined by the reflector (s), the lens plates, and the heat sink. One or more light sources (402) disposed along the heat sink mount surface emit light into the interior cavity where it can be mixed and/or shaped before it is emitted.
