  • Automatic relamping system
    Patent number: 4862038
    Abstract: An automatic relamping system that provides for operation of a single one of multiple illumination lamps with automatic illumination of a next lamp upon failure of an illuminated lamp. A drive circuit is provided for the multiple lamps including an oscillator and means for connecting the multiple lamps in a parallel circuit with the drive circuit. The connections between lamps include direct conductive conductors so that upon starting of any one of the multiple lamps and ignition thereof, the other lamps are inhibited from ignition due to the reduced "on" voltage, in comparison to the "starting" voltage, of the ignited lamp.
