摘要： A lamp capsule for use in a vehicle headlamp includes a lamp envelope having a tubular portion. First and second spaced-apart filaments are mounted in the lamp envelope for emitting light when energized by electrical energy. The lamp capsule further includes one or more light-attenuating axial stripes on the lamp envelope. The axial stripes are positioned on the lamp envelope for blocking light emitted by the first filament and reflected by the second filament. The lamp capsule may further include light-attenuating rings at or near opposite ends of the lamp envelope for defining upper and lower boundaries of a clear region of the lamp envelope. A filament support structure may include support leads located in the plane of the filaments for limiting light blockage and stray reflections.

摘要： In first to third support wires (12, 13, 14) connected to a low beam filament L and a high beam filament H, which are arranged in the light source bulb 9, a bent portion 13a is formed by bending the second support wire 13 from a curved portion 13c towards the first support wire at an obtuse angle &thgr;2, and each rear lead Lb, Hb of the low beam filament L and the high beam filament H is connected to the bent portion 13a. Moreover, a bent portion 14a is provided by bending the third support wire 14 from a curved portion 14c towards the second support wire at an obtuse angle &thgr;3, and a front lead Ha of the high beam filament H is connected to the bent portion 14a. The extended portions 13b and 14b of the second support wire 13 and the third support wire 14 are inclined at an obtuse angle &thgr;4, &thgr;5, respectively.
