- 광원과,상기 광원에서 발광된 빛이 입사되는 입사면 및 상기 입사면에 입사된 빛이 조명광으로서 발광되는 사출면을 갖는 광학 부재를 포함하는 조명 장치에 있어서,상기 광학 부재는 상기 사출면과 대향되도록 배치되어 입사면에 입사된 빛의 상기 광학 부재 내에서의 진행 방향을 규제하면서 빛을 사출면으로 안내하기 위한 광방향 전환면을 더 구비하고, 상기 광방향 전환면에 전반사면 및 재입사면을 갖는 복수의 프리즘형 부위가 연속적으로 형성되고,상기 광학 부재 내를 진행하여 상기 프리즘형 부위 중 하나의 전반사면에 도달한 빛 중, 소정 각도 성분의 빛만이 상기 전반사면 상에서 상기 사출면을 향해 전반사되고, 상기 전반사면에서 전반사되지 않은 소정 각도 성분 이외의 빛은 상기 하나의 프리즘형 부위에서 굴절되어 상기 광학 부재 외측으로 일단 안내된 후에 상기 하나의 프리즘형 부위에서 이어지는 프리즘형 부위의 재입사면을 통해 상기 광학 부재로 다시 안내되는 것을 특징으로 하는 조명 장치.
- 제1항에 있어서, 상기 사출면에 대한 전반사면의 각도 Φ는π/6(rad) ≤ Φ ≤ π/4(rad)의 부등식을 만족시키도록 설정되는 것을 특징으로 하는 조명 장치.
- 제1항에 있어서, 상기 사출면에 대한 전반사면의 각도 Φ는 각각의 프리즘형 부위에 대해 일정한 값으로 설정되는 것을 특징으로 하는 조명 장치.
- 제1항에 있어서, 상기 사출면에 대한 전반사면의 각도 Φ는 입사면에서 더 먼 프리즈형 부위일수록 더 작게 되도록 설정되는 것을 특징으로 하는 조명 장치.
- 제1항에 있어서, 상기 프리즘형 부위의 전반사면과 재입사면의 교차점으로 형성된 점들을 연결하는 포락선은 상기 입사면으로부터 떨어진 위치를 향해 변화하여, 상기 광학 부재의 두께는 상기 입사면으로부터 떨어진 위치를 향해 점차 얇아지는 것을 특징으로 하는 조명 장치.
- 제1항에 있어서, 상기 프리즘형 부위의 전반사면과 재입사면의 교차점으로 형성된 점들을 연결하는 포락선은 상기 입사면으로부터 떨어진 위치를 향해 변화하여, 상기 광학 부재의 두께는 상기 입사면으로부터 떨어진 위치를 향해 점차 두꺼워지는 것을 특징으로 하는 조명 장치.
- 제1항에 있어서, 상기 프리즘형 부위는 소정의 피치 D에서 연속적으로 형성되고, 상기 피치 D는0.2(㎜) ≤ D ≤ 4.0(㎜)의 부등식을 만족시키는 것을 특징으로 하는 조명 장치.
- 제1항에 있어서, 상기 프리즘형 부위는 소정의 피치 D의 간격으로 형성되고, 상기 소정의 피치 D는0.2(㎜) ≤ D ≤ 4.0(㎜)의 부등식을 만족시키도록 설정되는 조명 장치.
