Abstract

본 발명은 산업상 충분히 이용할 수 있을 만한 광강도를 가진 카드뮴램프를 염두한 발광장치에 관한 것으로써, 본 발명은 발광관(1) 내부에 양극(2)과 음극(3)이 짧은 간격(d)을 두고 배치되며, 점등시동을 용이하게 하기 위한 버퍼가스와, 발광물질로서 1×10-4ｇ/㎤ ~ 3×10-3ｇ/㎤의 금속타드뮴이 봉입된 카드뮴램프와,이 카드뮴램프의 음극(3)과 상기 양극(2) 사이에 전기입력을 공급하는 전원장치(20)를 구비하고, 전원장치(20)로부터 카드뮴램프에의 정상점등시의 전기입력을 W(kw), 상기 카드뮴램프의 발광관(1)의 최대내부반경을 r(㎜)로 했을 때, 0.5kw 내지 5.0kw의 전기입력 범위에 있어서, 6.03 + 2.79Wr
