摘要
分析了不同颜色半导体发光二段管(Light Emitting Diode,简称LED)光源在雾中的穿透性能,研究了淡水雾和海雾天气对LED信号灯的影响.结果表明,各种颜色LED在雾中与距离的关系随指数下降,淡水雾以及海水雾对黄光的透过率最大,为LED信号灯、探照灯等功能照明设计时的LED波长以及白光LED色温的选择提供了依据.
The penetration performance in mist of LED light source with different colors was experimentally analyzed.The influence of misty rain and sea mist to LED signal lights was studied.The result showed that the penetration distance of LED lights decreased exponentially in mist.Among different colors of LED light,yellow LED had the best transmittance both in misty rain and in sea mist.The result is useful for the design of functional lighting such as semaphores or searchlights.
