Abstract

본 발명은 여기상태의 이온으로 부터 방출되는 공명선을 이용한 단파장 자외선의 출력이 높은 방전램프에 관한 것으로서, 전극간 거리가 12mm 이하인 1쌍의 전극을 가진, 전극안정화형 램프이며, 주발광물질로서 동작시의 분압력이 3×103pa∼1.3×105pa가 되는 양의 카므듐이 봉입되고, 램프전류(JL)가 하기 조건(i)을 만족하는 상태에서 점등되는 것을 특징으로 한다.
조건(i) 0.7＜JL＜Pl/4＜15.0
또, 주발광물질로서 동작시의 분압력이 1×103pa∼0.3×105pa가 되는 양의 아연이 봉입되며, 당해 주발광물질의 동작시의 분압력을 P, 램프전류(JL)가 하기의 조건(ii) 만족하는 상태에서 점등되는 것을 특징으로 한다.
조건(ii) 0.7＜JL＜Pl/4＜16.9
