Abstract

In this paper, an aircraft warning light's optical system was designed using an LED light-source module and a collimating Fresnel lens. As for the optical system, a collimator Fresnel lens was designed for each module to satisfy a vertical-elevation center luminous intensity of 20,000 cd and the divergence-angle luminous-intensity standard conditions of the Ministry of Land for Infrastructure and Transport for aircraft warning lights. In addition, the optical system was optimized by adjusting the position and tilt of the LED light-source module and Fresnel lens. By analyzing and comparing the light-distribution characteristics of the optical system, an aircraft-warning-light optical system with optimal performance was obtained.

본 논문에서는 LED 광원 모듈과 시준용 프레넬 렌즈를 이용하여 항공기 장애등 광학 시스템을 설계하였다. 설계된 광학계는 국토 교통부 항공기 경고등의 수직 양각 중심 광도 20,000 cd와 발산각 광도 규격 조건을 만족시키기 위해 프레넬 렌즈를 모듈별로 설계하였다. 또한 LED 광원 모듈과 프레넬 렌즈의 위치와 기울기를 조정하여 광학 시스템을 최적화하였으며, 이렇게 설계된 광학계의 배광 특성을 분석하고 비교하여 최적의 성능을 가진 항공기 경고등 광학계를 설계하였다.
