Patent attributes
A fire resistant recessed luminaire constructed of an outer steel enclosure having a cylindrical shape that is open at one end and provided with a closed base at the opposite end. The open end has a shoulder extending outward from a perimeter of the outer steel enclosure. A fire insulation layer is disposed within and against the outer steel enclosure so as to conform to an inner shape of the outer steel enclosure. An inner steel enclosure is disposed within the fire insulation layer so as to force the insulation layer against the closed base and inner side wall of the outer steel enclosure. A light diffuser has a reflector trim extending outward from a second perimeter about an open end disposed in the inner steel enclosure so as to rest against a rim extending outward from an open end of the inner steel enclosure.
