Claims (7)
- 두개 이상의 집광렌즈와, 상기 집광렌즈의 초점과 집광렌즈의 사이영역에서 상기 집광렌즈를 향해 각각 배치되는 광원이 형성된 합성광원부;상기 집광렌즈에 의해 굴절된 조명을 일측을 향해 제공하는 집광부;를 포함하며,상기 집광렌즈는 초점보다 가까이 배치되는 광원에 의해 허상점(virtual image point)이 초점보다 먼 지점에 형성되며, 상기 집광렌즈들은 각각의 허상점들이 공통의 한 지점에 위치하도록 배치되는 것을 특징으로 하는 조명광학계.
- 제 1항에 있어서,상기 두개 이상의 집광렌즈들은 서로 인접 배치되는 것을 특징으로 하는 조명광학계.
- 제 2항에 있어서,상기 집광렌즈들은 초점길이가 서로 동일한 것을 특징으로 하는 조명광학계.
- 제 3항에 있어서,상기 집광렌즈들은 초점길이가 서로 다른 것을 특징으로 하는 조명광학계.
- 제 3항 또는 제 4항에 있어서,상기 집광부는 상기 합성광원부의 집광렌즈들을 통해 방사형으로 제공되는 광속을 집속시켜 일측 방향을 향해 제공하는 포물면 형태의 반사경으로 이루어지는 것을 특징으로 하는 조명광학계.
- 제 3항 또는 제 4항에 있어서,상기 집광부는 상기 합성광원부의 집광렌즈들을 통해 방사형으로 제공되는 광속을 집속시켜 일측 방향을 향해 제공하는 타원면 형태의 반사경으로 이루어지는 것을 특징으로 하는 조명광학계.
- 제 3항 또는 제 4항에 있어서,상기 집광부는 상기 합성광원부의 집광렌즈들을 통해 방사형으로 제공되는 광속을 집속시켜 일측 방향을 향해 제공하는 굴절광학렌즈로 이루어지는 것을 특징으로 하는 조명광학계.
