Radiation emitting system with pulse width and frequency control

摘要

The system includes a radiation emitter which is pulse driven by high current, low voltage full wave rectified direct current electrical power. Pulse frequency and width are controlled to provide periods of non-emissive operation sufficiently longer than the periods of emissive operation to maintain a desired emitter temperature. An electrically conductive case mounts the emitter in electrically conductive relation therewith and provides one current path to the emitter.
