Claims (3)
- 제1 및 제2전극 사이의 방전에 의해 광을 조사하는 램프와;상기 램프의 일측에 설치되며, 상기 램프 쪽에서 입사된 광을 집속반사시키는 제1반사부재와;상기 램프를 사이에 두고 상기 제1반사부재에 대향되게 배치되는 것으로, 상 기 램프에서 직접 조명된 광과 상기 제1반사부재에서 반사되어 진행하는 광을 집속반사시키는 오목반사면과, 이 오목반사면의 광축 주변에 관통 형성되어 입사광을 투과시키는 투과공을 가지는 제2반사부재와;상기 램프 주변에 상기 제2반사부재에 대향되게 배치되며, 상기 오목반사면에서 반사되어 입사된 광이 상기 투과공 쪽으로 향하도록 재차 반사시키는 제3반사부재와;상기 제3반사부재에서 반사된 광이 일 점에 맺히도록 하는 광 집속수단;을 포함하는 것을 특징으로 하는 조명장치.
- 제1항에 있어서, 상기 제1반사부재는,입사광을 굴절 투과시키는 오목한 굴절투과면과, 상기 램프쪽으로부터 조사되고 상기 굴절투과면을 통해 입사된 광을 집속반사시키는 반사면을 구비하는 것을 특징으로 하는 조명장치.
- 제1항 또는 제2항에 있어서, 상기 광 집속수단은,상기 투과공에 배치되며, 상기 제3반사부재 쪽에서 입사된 집속광을 발산투과시키는 발산렌즈와;출사공이 입사공 보다 상대적을 작은 직경을 갖도록 배치되며, 상기 발산렌즈를 투과한 광을 집속하는 깔때기형 반사집속관을 포함하는 것을 특징으로 하는 조명장치.
