-11- BRIDGELESS TUNGSTEN HALOGEN LAMP ABSTRACT A single-ended, tungsten halogen lamp having a tubular hard glass envelope containing an inert gas and a halogen, preferably bromine, therein. An improved bridgeless support structure is provided in which a wire support is attached to one end of a pair of filament coils. The wire support extends in two directions from the point of attachment and includes two extension portions which are each secured in the press-sealed base portion of the envelope to provide a fixed filament support with improved shock resistant capabilities and with reduced possibility of contamination due to elimination of the bridge element. A method of making the lamp is also described.
