为了展示LED在航空领域的应用优势和前景, 介绍了LED光源应用于飞机航行灯时, 具有体积小、质量轻以及便于设计和维护等优点, 阐述了LED用于飞机航行灯时的高安全性、高可靠性和高光学质量的要求。通过分析航行灯的光学分布要求, 针对选取的LED设计了由TIR系统和棱镜系统组成的光学透镜, 飞机航行灯光学模拟的结果显示, 在光源功率不超过1 W的情况下, 中心光强已经高于40 cd。

To show the advantages and prospects of LED applicated in the field of aviation , we introduced the LED light source used in aircraft navigation lights, which has the merit of small volume, light weight, easy design and maintenance, etc, and elaborated on the requirements of high security, high reliability and high optical quality for applying LED in aircraft navigation lights . Through the analysis on the optical distribution demands of navigation lights, we designed an optical lens which was consisting of total internal reflect (TIR) system and prism system according to the selected LED source. The optical simulation result shows that, the center optical intensity is more than 40 cd when the power consuming is less than 1W , indicating the LED navigation lamp has good optical performance.
