TROFFER-STYLE LIGHTING FIXTURE WITH SPECULAR REFLECTOR
First Claim
1. A lighting fixture, comprising:
- an elongated heat sink comprising a mount surface;
an elongated specular reflector proximate to said mount surface, said heat sink and said specular reflector arranged such that a spatial relationship is maintained between said heat sink and said specular reflector; and
a back surface proximate to said elongated specular reflector.

Abstract
An indirect troffer-style lighting fixture that is particularly well-suited for use with solid state light sources. An elongated heat sink with a mount surface for light sources runs longitudinally along the fixture. To facilitate heat dissipation, a portion of the heat sink is exposed to the ambient room environment. An elongated specular reflector also runs along the device proximate to the heat sink. The heat sink and the specular reflector are mounted such that a spatial relationship is maintained. Some of the light from the sources impinges directly on the specular reflector and is redirected towards a back surface. The back surface defines a luminous surface that receives light directly from the sources and redirected light from the specular reflector. The back surface and the heat sink mechanically obscure any images of the light sources in the specular reflector such that they are not visible in a viewing area.

31. A method of lighting a surface:
-
emitting light from a light source over a range of angles; redirecting at least a portion of said light with a specular reflector toward a luminous surface; receiving light directly from said light source and from said specular reflector at said luminous surface; and mechanically obscuring images of said light source on said specular reflector from a viewing area.
