Abstract
A system for driving a plurality of lamps is disclosed to balance currents flowing through the lamps by means of impedance matching. According to the multi-lamp driving system of the present invention, a balancing controller is employed to match the impedance of each lamp path so as to regulate currents flowing through the lamps to be substantially the same.
