TROFFER-STYLE OPTICAL ASSEMBLY
First Claim
1. A light engine unit, comprising:
- an elongated heat sink comprising a mount surface;
an elongated lens mounted on said heat sink and over said mount surface;
reflectors extending from both sides of said heat sink away from said elongated lens; and
a lens plate mounted proximate to said heat sink, said lens plate extending away from said heat sink to said reflectors, such that said heat sink, said reflectors, and said lens plate at least partially define an interior cavity.

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 surrounded by a reflective pan. An elongated heat sink comprises a mount surface for light sources. An elongated lens 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 extend out away from the heat sink on the mount surface side. A lens plate 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 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.
