An Automatic High-Pressure Mercury Arc Lamp Control Circuit

Lester F. Bird

A description is presented of a new high-pressure mercury arc lamp with associated control circuits in which optical inverse feedback is employed to produce an adjustable lamp capable of high stability and uniformity of output suitable for use in printers. Curves illustrating performance are included and discussed with possibilities for use of this lamp in variable-density recording.
