Abstract
A luminaire apparatus includes a housing having a source of radiant energy mounted therein, a rotatable light transmitting member supported at one side of the housing and reflector means. The reflector means consists of a stationary reflector body and expansible reflector means for controlling the configuration of radiation energy projected through the light transmitting member located between the stationary reflector body and the light transmitting member. In one desirable form the stationary reflector body is provided with a specular surface which projects reflected light in a spot configuration while the expansible reflector means is provided with light diffusing surfaces which are operable to progressively modify the spot configuration to provide a flood configuration. In another desirable form the specular and diffusing surfaces may be interchanged so that the stationary reflector body produces a flood configuration and the expansible reflector means is operable to modify the flood configuration to spot configuration. The expansible reflector means is engageable with the rotatable light transmitting member and comprises a plurality of reflector surfaces which are connected to one another.
