ABSTRACT:
An infra-red lamp consists of a quartz tubular envelope sealed at each end with a respective pinch seal. A tungsten filament supported within the envelope is electrically connected, via a molybdenum foil strip and lead wires within the pinch seal to a connector for connection to a power supply. Each pinch seal is substantially wholly enclosed within a ceramic housing, which is preferably provided with a locating flange, to protect the pinch seal in part from heat emitted by the filament and to assist in location of the lamp in an operating environment.
