UV IRRADIATION APPARATUS

Disclosed is an UV irradiation apparatus with improved startability which is equipped with excimer lamps. The UV irradiation apparatus includes a plurality of excimer lamps each having a light-emitting tube filled with a discharge gas containing a noble gas. The plurality of excimer lamps includes a first excimer lamp filled with the discharge gas at a first enclosed gas pressure and a second excimer lamp filled with the discharge gas at a second enclosed gas pressure lower than the first enclosed gas pressure. The first excimer lamp is placed in a position such that at least part of light emitted from the second excimer lamp is allowed to enter the first excimer lamp. 本发明提供一种提高起动性的搭载有准分子灯的紫外线照射装置。紫外线照射装置具备多个准分子灯，该多个准分子灯具有封入有包含稀有气体的放电用气体的发光管。多个准分子灯包含以第一封入气体压力封入有放电用气体的第一准分子灯和以低于第一封入气体压力的第二封入气体压力封入有放电用气体的第二准分子灯。第一准分子灯被配置于来自第二准分子灯的出射光的至少一部分能够入射的位置。
