摘要：A dimming ballast system wherein the light output of the lamp is controlled bya remote source. The ballast output voltage is regulated by a voltage control feedback

loop, the dimming function being achieved by varying the set point of the control loop.The remote control signal, coded by interrupting the current flow to the ballast for ashort period, is processed digitally by a microcomputer which generates information tovary the control set point. Circuit means are provided to control the filament voltage ofthe fluorescent lamps such that as the lamps are dimmed down, the filament voltage ismaintained or slightly increased, thus prolonging lamp life and stabilizing the lamp lightoutput.
