LED远距离可见导标灯设计
Long-range LED Pilot Lamp Design
摘要
本文根据光的大气传输理论、光度学和几何应用光学理论,设计了6 n mile(1 n mile=1.852 km)可见的LED海上导标灯。通过分析LED 的发光特性,设计并优化适当的集光、准直与匀光系统,将LED 线阵排列,使本设计实现6 n mile 处垂直方向10°发散角与水平方向3°发散角的出光要求。本设计方案可为不同吃水深度的航船选择正确的航道,具有一定的实际应用价值。
Abstract
The 6 n mile visible pilot lamp system is designed based on the theory of atmospheric transmission, photometry and application of geometry optics. LEDs are arranged in linear order and through analyzing the luminescence characteristics of LED, the appropriate system of light collecting, collimating and dodging are designed and optimized so that the design can distribute the light in vertical direction within 10 degrees and in horizontal direction within 3 degrees in a uniform manner in 6 n mile away. The design can be applied to help ships with different drafts to choose the right channel.
