Vibration resistant mount structure for double ended tungsten-halogen lamp.

摘要

A mount structure for a double ended type tungsten - halogen lamp (30) is disclosed employing a vibration damping element (32) to reduce the effects of mechanical shock and vibration. The vibration damping element has a planar body portion (56) which is physically joined (as by tabs (42)) to the lamp envelope (38), and electrically connected (as by tab (58)) to a lamp inlead (48). A thin layer of ceramic cement is preferably interposed between the mount structure and lamp to improve the sealing arrangement related to a quartz lamp. sealed beam headlamp unit employing the improved lamp mount construction is also disclosed.
