Abstract

The method ensures mechanical centering and firm seating. Preforming of the reflector base (3) limits passage of the bulb and forms two or four thrust points pressing the bulb and two or four holes for convection cooling. The pressure points are obtained in stamping the reflector base, the other parts are not deliberately stamped and form ventilating holes. A grooved metal ring is embedded in the base of the reflector. The fitting is partic. for mirror type lamps, used in projectors.
