ABSTRACT:
The present invention relates to an apparatus and method for receiving a modulating signal, splitting up its various frequency components into separate channels using a plurality of filters, and applying the outputs of the filters to gas discharge lamp modulating circuits to analogously vary the light output of each lamp. The present invention processes the modulation signal through a control circuit, a peak voltage detector, a current source, an ionization voltage supply, a filter circuit, a voltage multiplier and a modulating circuit to the gas discharge lamps. Optocoupling elements are implement in the present invention to control the circuitry. The gas discharge lamps have a rectifying element connected between each gas discharge lamp to prevent the gas discharge lamps from being connected to neutral by the filament of an adjacent gas discharge lamp.
