ABSTRACT:
A recessed incandescent ceiling light fixture is provided with a heat sensing device for interrupting current flow to an incandescent bulb mounted in the fixture. The top wall of the fixture is encompassed within a cover member which is spaced from the top wall, the cover member including a depending skirt which outwardly laps the sidewalls of the fixture and defines a circumferential slot between the fixture walls and cover member. A heat sensor is mounted on the surface of the cover member in the area between the top wall of the housing and cover member. The cover member is mounted to the housing at spaced points whereby heat transfer from the housing to the cover member is minimized.
