摘要： The electric lamp has a lamp vessel (1) having an end portion (3) which is fixed in the lamp cap (5) by means of polyethersulphone (8) as a thermoplastic synthetic resin, which has adhered both to the lamp vessel and to the lamp cap. The end portion (3) has non-circular cross-sections where it is in contact with the synthetic resin (8) due to projections (10) projecting into the synthetic resin (8). A current supply wire (11) can be clamped between the synthetic resin (8) and the sheath portion (6) of the lamp cap (5) in order to establish electrical contact therewith. The lamp can be assembled by arranging in the hot state of the end portion (3) a polyethersulphone ring (8) around this end portion (3) and by providing the lamp cap (5) in the hot state around the polyethersulphone ring (8).

摘要： A lamp comprising an envelope part and a cap part . The envelope part has a pinch part (4) provided with two parallel lead-in conductor wires (10) extending outwards beyond said pinch portion (4) . The cap part has two contact members for contacting corresponding electrical contacts of a lampholder. Each conductor wire (10) is connected to a corresponding contact member of the cap part . Two flat surfaces (14) are present at both sides of the pinch part (4) , said surfaces (14) being parallel to the plane through said conductor wires (10) . Clamping elements (8) of the cap part about against said surfaces (14) to provide a fixation of the envelope part relative to the cap part .

摘要： A holder 6 having a funnel-shaped portion is provided above an eyelet 5, and a conductive metal piece 11 is supplied to the vicinity of a portion at which plasma arc welding is performed in the funnel-shaped portion. The conductive metal piece 11 is fused together by plasma arc welding so that the hole 9 of the eyelet is closed completely. Thus, the lead wire 8 can be connected firmly. Therefore, even if the hole diameter of the eyelet is excessively large relative to the diameter of the lead wire, complete closure and sufficient fusion connection can be achieved.

摘要： An electric lamp including a reflector (11), at least one conductive ferrule (25) located within a surface of the reflector (11) and a lead-in conductor (21) electrically connected to the ferrule (25) and extending within the reflector (11). The lamp includes a base (23) having an insulative (e.g., ceramic) cap (29) located substantially about the ferrule (25), barrier means (41) (e.g., ceramic fiber) located within the cap to define an open chamber substantially about the ferrule (25), an electrical conductor (35) (e.g., wire) extending within the cap (29) and electrically connected (e.g., silver soldered) to the ferrule (25), and sealing means (45) (e.g., high temperature cement) located within the cap to provide a seal therefore. The barrier means (41) serves to separate the sealing means (45) from the open chamber (43) about the ferrule such that the heat generated by the ferrule can be vented through spaced apertures (51) located within the cap's side wall. A method of assembling a base on an electric lamp is also provided.

摘要： The invention provides an improved method of construction of a prefocus lamp, to improve positioning of the filament relative to the lamp cap, and a lamp so made.
The lamp envelope (11) has a pinch seal (19) with V-shaped grooves (35) into which a resilient ring (25) is sprung. This assembly is a sliding fit in the lamp cap (12) and is slid therein to have substantially only line contact between the ring and the cap. The envelope can then be relatively easily rocked and otherwise moved in the lamp cap to be precisely positioned. When the positioning is complete solder (33) previously placed in the cap is melted, the position being such that it flows over the ring and fixes the ring to the lamp cap.
