DEVICE FOR EMITTING ULTRAVIOLET LIGHT

The present invention is to provide an ultraviolet irradiation device equipped with one or more excimer lamps that emit light with a center wavelength in the range from 200 nm to 230 nm. A device (100) for emitting ultraviolet light includes: at least one excimer lamp (12) having a discharge vessel (13) filled with light-emitting gases; a pair of first and second electrodes (14, 15) that are placed in contact with the discharge vessel (13) and produce a dielectric barrier discharge inside the discharge vessel (13); a housing (11) configured to house the excimer lamp(s) (12), and have a light-emitting window that allows light with a center wavelength in a range from 200 nm to 230 nm emitted from the excimer lamp(s) (12) to emit, wherein the housing is made of an insulating and heat-resistant resin material, and the housing forms a closed space for accommodating the excimer lamp (s). 提供一种紫外线照射装置，搭载有放射在波长200nm～230nm具有中心波长的光的准分子灯，具备通用性更高的装置构造。紫外线照射装置(100)具备：准分子灯(12)，具有被封入发光气体的放电容器(13)、和与放电容器(13)抵接而配置且使放电容器(13)的内部
