ABSTRACT:
A discharge tube lighting apparatus is used to drive a plurality of discharge tubes. The apparatus includes a balance coil having a winding input end and a plurality of winding output ends to which the discharge tubes are connected individually; a power section for supplying ac current to the winding input end of the balance coil; and a control section for detecting a peak value of detection voltages corresponding to voltages at the winding output ends of the balance coil and for stopping the supply of the ac current from the power section when the peak value of the detection voltages is higher than a predetermined value.
