ABSTRACT:
A discharge lamp lighting device driven by an internal combustion engine is disclosed which is capable of lighting a discharge lamp without using a ballast constituted by a leakage transformer. The device includes a generator which is driven by the internal combustion engine and of which output characteristics exhibit drooping characteristics, so that an output voltage of the generator may be applied to a discharge lamp without using any ballast. Output characteristics of the generator are so set that an output voltage of the generator at a non-load state thereof may be higher than a break-down voltage of the discharge lamp, a short-circuit current of the generator may have a level sufficient to restrict a discharge current of the discharge lamp just after starting of discharge thereof to an allowable level or below, and a voltage across the discharge lamp and a discharge current thereof at a steady state thereof each are kept within a rated range.
