ABSTRACT:
A lamp control system driving at least two discharge lamps according to at least two control instructions includes a control circuit, a switch circuit, a transformer resonance circuit, and a source transformer circuit. The control circuit generates a control signal to which the source transformer circuit is electrically connected, transforming the control signal to at least one alternating current (AC) signal, and the transformer resonance circuit is electrically connected to the source transformer circuit and the discharge lamps, transforming the at least one AC signal to one or more electrical signals to respectively drive one or more discharge lamps, the switch circuit, electrically connected to the source transformer circuit and the transformer resonance circuit, drives source transformer circuit output of the at least one AC signals to the transformer resonance circuit.
