Abstract:

A lighting fixture is disclosed for accommodating a bulb parallel to its opening and that has a reflector made from a thin metal sheet located behind the bulb. At each socket housing location, the reflector is slit and an arc piece is formed from the released metal segment. The arc piece forms an effective shield over the socket and related components. Thus, the reflector and shield or shields are formable in a single action stamping step by appropriate manufacturing equipment.
