    摘要: An improved metal-halide arc discharge lamp (5) includes an arc tube (31) having a substantially cylindrical body surrounded laterally by a substantially cylindrical heat-conserving sleeve (23) within an evacuated outer envelope (7). The ratio of the outer radius of the arc tube (31) divided by the inner radius of the sleeve (23) falls within an optimum range of approximately 0.54 to approximately 0.68, and preferably within a range of approximately 0.60 to approximately 0.63. A lamp constructed in accordance with the invention exhibits improved luminous efficacy and color rendering in comparison to prior art counterparts. The improved performance is believed to be attributable to the more nearly isothermal operation of the arc tube for a given wall loading.

    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: Disclosure is given for a method of forming and treating an arc tube (14), preferably for a metal halide lamp, such that end pockets (10) or other internal tube irregularities are eliminated. In one preferred embodiment the unwanted pockets are eliminated during the manufacturing process of the arc tubes. Therefor a press seal machine with 4 presses (2 pairs) was designed to provide pressing capability in two mutually perpendicular planes. With this machine a first press is made in the conventional manner with two opposing press feet (20, 22) being driven into the hot quartz of the arc tube body. While these feet are still in contact with the hot quartz, a second pair of press feet (24, 26) enter from the sides to flatten the sides of the press, and to dimple in the quartz with the press at arc chamber junction area (16) where end pockets are normally formed.
