Abstract
A non-electrode discharge lamp apparatus comprises a discharge tube, exciting coils wound on an outer periphery of the discharge tube, a vessel, having liquid-tightness, containing the discharge tube and the exciting coil means, and lead line guiding means for guiding lead lines connected to the exciting coils to the outside of the vessel, thereby supplying high frequency electric power to the exciting coils through the lead lines. Liquid is prevented from directly contacting the discharge tube and the exciting coils, temperature of the discharge tube can be suitably maintained, and an irradiation efficiency of ultraviolet rays can be prevented from being reduced.
