Abstract
A high-voltage transformer for lighting a plurality of discharge lamps has a primary coil for inputting an AC voltage and a secondary coil for outputting a predetermined AC voltage higher than the AC voltage inputted. The primary coil has a starter primary winding for initially lighting the discharge lamps, and a normal lighting primary winding for normally lighting the discharge lamps.
