ABSTRACT:
The present invention comprises a light fixture including a housing, a light source, means to secure a light source to the housing, a lens and a reflector. The reflector and lens are positioned so as to direct light from the light source onto an unlit side of the housing.
The light fixture is normally suspended from the ceiling or attached to a wall. A greater portion of the light from the light source is reflected off the ceiling or wall, whereas a smaller portion of the light from the light source is reflected off the reflector and onto the housing. After the smaller portion is reflected off the housing, the smaller portion and the larger portion are traveling in generally the same direction, thereby reducing the contrast between the housing and the ceiling or wall.
The present fixture housing is very shallow, preferably less than about 3" deep. It includes one or more side rails, with each side rail being utilized to reflect the light from the light source onto the housing with a first reflector and to alter other diffuse lighting characteristics with a lens, perforated metal, or a second reflector.
