Abstract

본 연구에서는 기존 LED 보안등의 LED 광원 직진성에 의한 눈부심 현상을 개선하고, 조도 균제도를 높게 유지하며, 회전 대칭이 아닌 편축으로 긴 배광 분포를 가지도록 하여 LED 보안등 간에 생기는 광 공핍현상을 해결할 수 있는 보안등용 LED 2차 렌즈를 개발하였다. 개발 광학계는 보안등용 조명 기준에 만족하도록 설계하였으며, 렌즈의 형태는 단일 렌즈로 조명 설계 및 해석 프로그램을 이용한 설계와 분석을 통해 최적화를 하였다. Mock-up을 제작하여 실제 측정을 통해 조도 측정 데이터와 조도 균제도 데이터를 확보하였다. In this paper, we develop about glare phenomenon at security light caused by light source's straight characteristic, maintaining uniformity ratio of illuminance as high, have long light distribution not by symmetry of rotation but a single axis. we develop second lens for security light that lack of light distribution phenomenon at each of security light can be solved. Our developed light system design satisfies lighting standard of security light's and shape of lens is single lens. so our lens optimizes designing or analysis by using lighting design and interpretation program. Making a Mock-up to do real measure, we have intensity of illumination and maintaining uniformity ratio of illuminance measurement data.
