ABSTRACT:
An electric lamp assembly is disclosed which comprises a bulb unit including a filament, lead lines extending from the filament to the outside of the bulb unit and a hermetic seal portion, the lead lines extending through the hermetic seal portion; a bulb holder including a looped band portion which gripps the hermetic seal portion of the bulb unit having leading ends of the lead lines projected outward from the bulb holder, the bulb holder having foot portions each being formed with at least one opening; and a base assembly including a circular body part, a pair of conducting plate members having leading ends projected outward from respective slits formed in the body part and a plurality of supporting pins extending outward from the body part. The supporting pins are inserted into the openings of the foot portions of the bulb holder and welded to the foot portions to achieve a tight connection between the base assembly and the bulb holder. In order to facilitate mating between the leading ends of the lead wires and the leading ends of the conducting plate members, there is further employed a guide structure which guides the leading ends of the lead wires to give portions of the conducting plate members upon coupling of the bulb holder and the base assembly.
