New Xenon Compact-Arc Projection Lamps for Horizontal Operation

H. S. Strauss, W. E. Thouret, J. Leyden, H. Kee, T. W. Hunt

Xenon compact are lamps are used increasingly instead of carbon arcs in motion-picture theater projectors and studio-lighting equipment. Such lamps have to perform with great reliability and must operate in horizontal position in order to be economic and efficient in up-to-date optical systems. The properties of four new-lamp types are described that meet these requirements. Three of these lamps are in the medium wattage range between 2000 and 4500 W and have conventional radiation-cooled electrodes. The fourth type can be operated reliably with inputs from 10 to 25 kW and has liquid-cooled electrodes. It should become useful for drive-in theater projectors and other equipment with great light-output requirements.
