두 가지 렌즈 단면의 직교 결합에 의한 3차원 LED 렌즈 구현과 조명 성능 향상을 위한 최적화 과정의 복합 균제도 활용

초록

A non-imaging 3-dim. LED lens was implemented with the orthogonal coupling of two lens cross-sections optimized independently, and a complex illuminance uniformity was newly utilized for improving the performance degradation of 3-dim. lens compared to those of lens cross-sections. The optimal constituent ratio of the luminous efficiency and the illuminance uniformity for merit function was found and the performance of 3-dim. lens could be improved greatly.
