New Xenon Compact-Arc Projection Lamps for Horizontal Operation
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.
