VEHICLE LAMP WHICH HAS GLARE CONTROL

摘要

PROBLEM TO BE SOLVED: To provide a lamp capsule for use in a vehicle headlamp and including a lamp envelope having a tubular part. SOLUTION: In the lamp capsule, first and second set-apart filaments are mounted in the lamp envelope for emitting light when it is 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 both 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 containing the first and the second filaments for limiting light blockage and stray reflections.
