ABSTRACT:
Apparatus for use in a lighthouse station for automatically maintaining the output of the light source at a predetermined level comprises a chamber for supporting a cathode ray tube face panel and a source of actinic energy located in the chamber. An adjustable controller is employed for energizing the source. A light translator in the form of a quartz rod is disposed adjacent the energy source for monitoring its output. A light responsive device, coupled to the light translator, derives a control signal representative of the instantaneous energy level of the light source. Finally, means responsive to the control signal serves to actuate the controller to maintain the output of the source at a predetermined level.
