  • Tungsten halogen incandescent lamp having an improved mounting structure
    Patent number: 4578616
    Abstract: A single-ended tungsten halogen incandescent lamp having an improved mounting assembly for a planar multi-filament is disclosed. The improved mounting assembly comprises, in part, means rigidly located in the pinch seal end of the lamp for coupling the outer lead-in wires to support rod members of the mounting assembly. The means for coupling comprises a first foil member and a first tab member, and a second foil member and a second tab member. The foil members and tab members are arranged with the outer lead-in wires and support rods to form a torsion bar-like configuration which holds the planar multi-filament in the central region within the lamp itself. The torsion bar-like configuration also finds application to lamps other than this tungsten halogen incandescent lamp.
