A discharge lamp driving device for driving a lamp module ( 23 ) including a plurality of lamps includes a switch circuit ( 21 ), a transformer and filter circuit ( 22 ), and a microcontroller ( 20 ). The switch circuit converts a received signal to an alternating current signal. The transformer and filter circuit is connected between the switch circuit and the lamp module, for amplifying and shaping the alternating current signal. The microcontroller connected to the switch circuit for outputting a control signal to control the switch circuit to output the alternating current signal to the lamp module. In the invention, correlative parameters and specifications of the circuit are predetermined via the microcontroller. Therefore, the structure of the whole circuit is simple.
