Abstract:
1. A discharge lamp driving device for driving a plurality of discharge lamps, comprising: a control circuit board, configured with a control circuit, for converting a received power signal to a first high voltage signal and a second high voltage signal for driving the discharge lamps; a first connecting board, configured with a first balancing circuit connecting with one end of each of the discharge lamps, for balancing currents flowing through the discharge lamps; a second connecting board, configured with a second balancing circuit connecting with another end of each of the discharge lamps, for balancing currents flowing through the discharge lamps; a first set of high-voltage transmission lines, connecting the control circuit board to the first connecting board, wherein the control circuit transmits the first high voltage signal to the first balancing circuit by way of the first set of high-voltage transmission lines; and a second set of high-voltage transmission lines, connecting the control circuit board to the second connecting board, wherein the control circuit transmits the second high voltage signal to the second balancing circuit by way of the second set of high-voltage transmission lines.
