专利汇可以提供Tungsten halogen lamp having improved filament support专利检索，专利查询，专利分析的服务。并且A tungsten halogen lamp has a coiled coil filament tensionally mounted and axially disposed within a fused silica tubular envelope. A support rod extends substantially parallel to the filament for at least the entire length thereof. The filament is supported at one or more points throughout its length by means of suitable arms connected to the support rod or by loops in the rod itself. The ends of the support rod can be fixedly attached to rigid lamp members or one end may be slidably supported to permit longitudinal thermal expansion of the rod.，下面是Tungsten halogen lamp having improved filament support专利的具体信息内容。

权利要求

1. A tungsten halogen lamp comprising: an elongated fused silica envelop having press seals at each end thereof and a fill including a halogen; ribbon connectors hermetically sealed within said press seals; an elongated coiled-coil tungsten filament axially disposed and tensionally mounted within said envelope; internal lead-in wires connecting each end of said filament to a respective ribbon connector; external lead-in wires connected to said ribbon connectors; two silica bridges disposed within said envelope, one bridge near each end of said envelope, said bridges being supported by said respective internal lead-in wires; an elongated halogen-resistant means extending longitudinally within said envelope beyond both ends of said filament, said means supporting said filament and substantially preventing transverse displacement thereof, one end of said means being rigidly supported in one of said bridges and the other end of said means being slidably supported in the other of said bridges.

2. The lamp of claim 1 wherein the slidably supported end of said means is disposed within a tubular member embedded in a fused silica bridge.

3. The lamp of claim 1 wherein the slidably supported end of said means is disposed within a hole through a fused silica bridge.

4. The lamp of claim 2 wherein said tubular member comprises a tungsten coil wound at between about 100 to 200 percent pitch.
