Abstract:

An electric lamp is provided which includes a reflector typically made of glass or metal and having a reflecting surface in which an area is formed to fit a locating device attached to the internal capsule light source. At the rear of the reflector is a neck portion in which are located several seating points for the light capsule locating device. Electrical connectors extend between the capsule and the base member. The positioning member is definitely located by seating ledges molded into the neck of the reflector. In manufacture, the positioning member is placed in tension and the lead wires for the lamp assembly extend through eyelets in the base which are then mechanically fastened so as to maintain a tension on the positioning member. The fact that the positioning member is under tension allows it to maintain positional accuracy during the life of the lamp.
