Abstract: A combination light fixture and acoustic conditioner assembly particularly useful in modular room enclosures wherein the ceiling is spaced above the enclosure walls. The invention provides for indirect lighting means and means for masking external sounds in the vicinity of the light fixture assembly. The assembly includes a reflector positioned so that light and sound waves contacting the reflector are dispersed in a plurality of directions due to the concavity of the reflector and undulations therein and eventually contact the ceiling where they are further reflected and spread. Dispersion of sound waves in this manner provides a pleasant, unintelligible sound which masks external sounds that might otherwise distract occupants of the modular room enclosures.

Abstract: A free standing indirect lighting fixture utilizing a one-piece molded reflector and a diagonally mounted high intensity discharge lamp has a frosted diffuser over the lamp. Acoustic material on the fixture absorbs ballast hum as well as adding acoustic absorbtion to the room. A back lighted information strip may optionally be included.

Abstract: A translucent spherical lamp with dimmer switch and flasher controls, a radio receiver and microphone, and an externally grooved polygonal base.
