Claims (3)
- 엘이디(LED) 조명장치용 광학렌즈에 있어서,유리나 아크릴계 플라스틱 또는 PMMA 중에서 선택된 어느 하나로 이루어지되 내부 전체가 채워지는 몸체를 갖는 렌즈구조체이며;상기 렌즈구조체는 광원인 LED의 발산광이 입사되는 법선방향에 형성되어 렌즈구조체의 내측 표면을 이루게 되고 산과 골의 형태를 갖되 중심부분에 고드름과 같은 광조정돌부를 형성시킨 좌우 대칭구조이며 비구면으로 형성되는 아이시클 비구면 내면과,상기 렌즈구조체의 외측 표면을 이루게 되는 구면 또는 비구면에 의한 외면을 포함하는 구성인 것을 특징으로 하는 엘이디 조명장치용 아이시클형 광학렌즈.
- 제 1항에 있어서,상기 렌즈구조체는 아이시클 비구면 내면 중심에 형성시킨 광조정돌부의 끝단이 렌즈구조체에 장착되는 LED의 상면에 직접적으로 닿게 하거나 최대한 근접되게 돌출 형성시키는 것을 특징으로 하는 엘이디 조명장치용 아이시클형 광학렌즈.
- 제 1항에 있어서,상기 렌즈구조체는 LED의 발산광에 대해 직교좌표계에서 모자형 방사패턴을 형성하도록 광분포를 조정하게 되고, 구좌표계에서 방패형 방사패턴을 형성하도록 광분포를 조정하게 되는 것을 특징으로 하는 엘이디 조명장치용 아이시클형 광학렌즈.
