ABSTRACT:
A high pressure sodium lamp has a horizontal light source and is supported by a socket and frame which includes a horizontal reflecting plate member positioned below the lamp. A pair of open grid-type reflector panels are supported by the plate member on opposite sides of the lamp and at inclined angles to reflect light rays downwardly while preventing direct viewing of the light source through the panels. The frame is supported below the ceiling of a room, and in one embodiment, a rectangular open bottom and open top translucent shade surrounds the lamp and reflector panels. All light rays emanating from the light source are reflected within the room to produce 100% indirect lighting, and air flows upwardly through the panels and around the lamp to provide for cooling and self-cleaning of the lamp.
