电介质势垒放电灯点亮装置
摘要：
本发明的电介质势垒放电灯(14)，在紫外线透过性的呈细长管状的气密容器(141)内在管轴方向上配置有内部电极(142)，而气密容器(141)外密接半圆周形状的外部电极(143)配置。此外，气密容器(141)内封入受激准分子生成气体。电源(11)所供给的交流电压通过变换器(12)变换为直流电压来输出。根据变换器(12)供给的直流电压由逆变器(13)生成高频，在电介质势垒放电灯(14)中激发电介质势垒放电以放射紫外线。变换器(12)通过直流电源(121、122)的输出串联连接来构成。通过调整直流电源的数目，来针对规格不同的电介质势垒放电灯也实现最佳发光效率。
摘要（英）：

A dielectric barrier discharge lamp 14 has an inside electrode 142 in a tube axis direction within the airtight container 141, which has ultraviolet transmission properties and a long tube shape, and an outside electrode 143 having a semicircular shape arranged outside of the airtight container 141 in close contact with it. Besides, an excimer-forming gas is sealed in the airtight container 141. AC voltage supplied from the power source 11 is converted into DC voltage through a converter 12 and outputted. A high-frequency wave is generated by an inverter 13 based on the DC voltage supplied from the converter 12, and a dielectric barrier discharge is induced in the dielectric barrier discharge lamp 14 to irradiate ultraviolet rays. The converter 12 is configured by connecting in series the outputs of DC power sources 121, 122. Optimum luminous efficiency of a dielectric barrier discharge lamp having different specifications is also realized by adjusting the number of DC power sources.
