ABSTRACT:
A lighting circuit for a discharge lamp has input terminals to which a DC power supply is to be connected, a DC power supply circuit for converting a DC input voltage to a predetermined voltage, and a DC-AC converter for converting the output voltage of the DC power supply circuit to an AC voltage and then supplying the AC voltage to the discharge lamp. A transformer is incorporated in the DC power supply circuit as insulator means for insulating the circuit portion at its input stage from the circuit portion at its output stage. The transformer has its high-voltage output terminal connected to a ground-side one of the input terminals to supply a negative rectangular-wave voltage to the discharge lamp.
