Abstract
A thermally protected recessed lighting fixture includes a generally cylindrical housing divided by a partition into a closed upper chamber and an open-bottom lower chamber. A reflector assembly including a reflector and lamp socket is removably mountable in the lower chamber. The reflector assembly carries a thermally insulating and flame-resistant shroud which encloses its rear side and is generally conical in shape. In use, the shroud is spaced from the walls of the lower chamber to form a heat sink space therein. Conductors from the lamp socket extend through a slit in the shroud to a plug which is matable with a receptacle in the partition, the receptacle being connected to associated circuitry in the upper chamber.
