Modular indirect troffer

摘要

A modular troffer-style lighting fixture. The fixture is particularly well-suited for use with solid state light sources, such as LEDs. Embodiments comprise a pan structure designed to house one or more modular light engine units within a central opening. Each light engine unit includes a reflective cup that can house several light sources on an interior mount surface. The cup is positioned proximate to a back reflector such that its open end faces a portion of the back reflector. The back reflector is shaped to define an interior chamber where light can be mixed and redirected. At least one elongated leg extends away from the reflective cup toward an edge of said back reflector. The leg(s) are used to mount the reflective cup relative to the back reflector and may also be used as a heat sink and/or an additional mount surface for light sources.

1. A light engine unit, comprising:
a reflective cup comprising an interior mount surface; a back reflector proximate to said reflective cup, at least a portion of said back reflector facing said mount surface, said back reflector shaped to define an interior chamber; at least two elongated legs extending away from said reflective cup toward an edge of said back reflector; and a plurality of light emitting diodes (LEDs) on the perimeter of said interior mount surface.
