ABSTRACT:
An electrodeless discharge lamp device has an envelope in which a gas that discharges to emit light upon application of a high frequency voltage is sealed, the envelope including two straight pipe parts forming a circulating discharge path, so that a high frequency electric current is caused to flow throughout the discharging gas in the entire envelope and a uniform discharge light emission can be attained.
