    摘要: A tungsten-halogen lamp for use in an automobile headlight comprises a tubular sealed glass capsule containing two coiled tungsten filaments for high and low beam operation, respectively. The low beam fiiament is disposed substantially orthogonal to a vertical plane containing the lamp axis, with the center of that filament length having a predetermined offset from that vertical plane and being disposed at or near the focal point of the reflector. The high beam filament is disposed substantially parallel to the lamp axis on the opposite side of the vertical plane from at least a major portion of the low beam filament. The filaments are spaced apart with the high beam filament lying in a horizontal plane spaced below the low beam filament, and the axis of the high beam filament orthogonally intersects a plane containing in the axis of the low beam filament.

    摘要: A'lamp member is adapted for use in a lighting unit having a light transmitting cover. The lamp member comprises a base, a tungsten-halogen capsule supported within the base, a first envelope, and a filament structure axially oriented with the first envelope. The lamp member further includes spacer means for maintaining the lamp member and the cover in a spaced-apart relationship when the lamp member is in the spring-biased position within the housing. The spacer means is secured to the lamp member and is in operative contact with the cover. One example of the spacer means is a cylindrical cap made of a ceramic material, the cap being disposed at the top of the capsule and secured thereon. The cylindrical cap is dimensioned so that the size of the replacement lamp is substantially the same size as prior incandescent lamps of which the invention is designed to replace.

    摘要: A low wattage tungsten-halogen lamp with an improved filament construction comprising a pair of selectively activated filaments, each having a plurality of coil turns, being intercoupled by a relatively short intermediate member. Preferably, both of the filaments and the intermediate member are formed from a single wire. The spacing between turns of each filament is greater about the central portion of the filament than at the opposed end portions thereof, thereby enhancing visible radiation. Xenon gas, at a pressure of fifteen atmospheres, is preferably used as the inert gas fill for the lamp due to its low thermal conductivity.
