Abstract
In a discharge lamp lighting circuit 1 using a common starter circuit 5A to a plurality of discharge lamps 6i (i=1, 2, . . . , n) to start the discharge lamps 6, the starter circuit 5A has a transformer 7 comprising a plurality of secondary windings 7bi (i=1, 2, . . . , n) provided for a primary winding 7a. A primary circuit 8 comprises a capacitor 9 and a switch element 10 and the generated voltage when the capacitor 9 is charged when the switch element 10 conducts is increased by the transformer 7, then is applied through each secondary winding to the corresponding discharge lamp.
