Comprehensive analysis for LED airport runway centerline lamp

In recent years, LEDs are applied in many novel illumination fields, and LED airport runway centerline lamp is a relatively new application in airfield lighting. While such lamps used in the runway of airport have strict requirements including mechanical reliability and optical illumination requirement, such as color, luminous intensity and incident angle etc [1, 2]. As we all know, there exists strong shock and vibration when the aircraft lands or taxis on the runway, which inevitably causes many adverse effects for lamps reliability. Besides, different operating situations have different lighting intensity distribution requirements, the assembly methods for prim and lens of lamp have to be carefully considered to meet illumination requirements. In this paper, a novel LED airport runway centerline lamp is designed, and then mechanical reliability and optical intensity distribution are simulated based on different operating situations. The simulation results show that the novel LED airport centerline lamp meets requirements of relevant standards of airport lamps.
