Abstract

A lighting device which lights a high intensity discharge lamp (7) adds together a high-frequency component from high-frequency generating means (3) and a low-frequency component from low-frequency generating means (4) in adding means (6) and supplies a superimposed wave current containing the high-frequency component and low-frequency component to the high intensity discharge lamp (7) to light the same.
