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.
