ABSTRACT:
A flush mounted ceiling fixture canopy molded of a polycarbonate (or other suitable) resin attachable to a conventional electric connection box in the ceiling. The canopy has a peripheral frame and a canopy body positioned centrally in the frame. The canopy body has a depending wall defining an insulating air space. There is an insulative layer below the canopy. Light bulbs are positioned below the insulative layer and, in part, below the air space to insulate the connection box from heat transfer from the bulbs. The canopy is structured so as to minimize the transfer of heat from the bulbs to the canopy structure.
