ABSTRACT:
Mounting device for rotatable adjustment of asymmetric reflector within luminaire housing to vary the light distribution from the luminaire. The mounting device includes a plurality of brackets circumferentially spaced around the lower portion of the dome-shaped luminaire housing for supporting the circular rim of the asymmetric reflector, which is formed with a corresponding plurality of recesses for clearing the brackets when the asymmetric reflector is inserted in or removed from the luminaire housing. Adjustable clamps are arranged adjacent the brackets for securing the reflector in the desired rotational position.
