Abstract
An electric-discharge-lamp lighting apparatus including: an inverter that converts a DC voltage to a high-frequency voltage; an insulating transformer for low voltage with a primary winding connected to an output end of the inverter; and a plurality of step-up transformers. In the electric-discharge-lamp lighting apparatus, a first series circuit formed by connecting primary windings of the plurality of step-up transformers in series to one another is connected to a secondary winding of the insulating transformer. In addition, one or more electric discharge lamps are connected respectively to secondary windings of the step-up transformers.
