Abstract:
A discharge lamp lighting device driven by an internal combustion engine, comprising:a generator without a ballast, said generator being driven by the internal combustion engine;said generator outputting a voltage which is applied to at least one discharge lamp;said generator being so constructed that output-voltage to output-current characteristics thereof exhibit drooping characteristics;said output-voltage to output-current characteristics of said generator being so set that an output voltage of said generator at a non-load state thereof is higher than a breakdown voltage of said discharge lamp, a short-circuit current of said generator has a level sufficient to restrict a discharge current of said discharge lamp just after starting of discharge thereof to an allowable level or below, and a voltage across said discharge lamp and a discharge current thereof at a steady state thereof each are kept within a rated range.
