Abstract

A discharge lamp lighting circuit comprises an inverter (3) for converting a DC voltage into a high-frequency voltage, a plurality of discharge lamps (11 to 15) to be lighted with the high-frequency voltage of the inverter (3), and a plurality of current transformers (CT1 to CT5) disposed to correspond to those discharge lamps (11 to 15). The current transformers (CT1 to CT5) have their secondary windings (21b to 25b) connected in series with the respective discharge lamps (11 to 15). Between the two adjoining ones of the current transformers (CT1 to CT5), the secondary winding of one current transformer is connected in series with the primary winding of the other current transformer, and the discharge lamps and the series circuits of the secondary windings of one current transformer and the primary windings of the other current transformer are individually connected in parallel with the two output terminals of the inverter (3).
