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.

Abstract: An electric lamp assembly which includes a bulb unit having a rectangularly shaped hermetic seal portion through which lead wires from a filament extend to the outside of the bulb unit, a bulb holder having a rectangularly looped band portion which grips the hermetic seal portion of the bulb unit with the lead wires projected outwardly from the bulb holder, a base assembly of moulded plastics supporting tightly the bulb holder and terminal members held by the base assembly and having inward ends projected toward the lead wires and welded to the same. The base assembly includes a hollow base structure and a rounded core structure which is coupled and welded to each other.

Abstract: A sealed beam lamp assembly, suitable for use as a motor vehicle headlight, has an incandescent lamp mounted within an inert-gas-filled, molded-glass housing integrally comprising a reflector and a control-lens cover. For supporting the lamp in position within the housing, a metal-made support rod extends forwardly from one of ferrules on the reflector and has its front end preformed into the shape of a U to provide a rearwardly directed fold. Welded to this fold of the support rod is a metal band rigidly encircling the base of the lamp. The lamp position relative to the reflector is therefore adjustable as required by manually turning the fold of the support rod about its main straight portion. The support rod serves also to provide electrical connection between the ferrule and one of the lamp leads.
