Tungsten halogen lamp for headlights

摘要

A tungsten-halogen lamp for use in motor vehicle headlights comprises a tubular sealed glass capsule containing two coiled tungsten filaments, parallel to each other and disposed substantially orthogonally to the axis of the capsule. The two filaments are offset laterally from each other and one of the filaments is a coiled coil, in order to reduce the lateral traverse of both filaments.
