民用机场LED停止排灯光学设计

随着LED光效的不断提升,其作为照明光源的技术也在不断探索发展中,这使得LED应用于民用机场灯光系统中成为可能.设计了一种民用机场滑行道LED停止排灯的光学系统,在光学设计软件Tracepro中建立模型进行了追迹模拟仿真,并通过分布式光度计测试其光学输出效果.实验结果证明,该系统结构可靠,光度学性能均达到国家标准的要求.该系统相比传统的卤钨灯光源,具有功率低、寿命长、抗震度好、低污染等优点,并且在提高整灯寿命的同时降低了整灯功率,符合国家"节能减排"的政策.

Optical Design for LED Stop Lamp in the Civilian Airport

With the continuous improvement of LED luminous efficiency and development of LED’s technology,the LED can be used in the civilian airport lighting systems.An optical system is proposed for LED stop lamp.The system model is built in the optical design software Tracepro for tracing simulation,and then,the lighting distribution is measured by a goniophotometer.The experiment results show that the system is reliable,and that the photometric properties have reached the national standard.Compared to stop lamp by traditional light sources,this system has several advantages such as low power consumption,long life time,good reliability and low pollution;furthermore,the system improves the whole lamp life due to the reduction of the whole power,which meets national policy ’Energy conservation and emission reduction’.
