Currently, most domestic airports use halogen-assisted lighting fixtures. However, some insiders believe that LED lighting is the future of navigation lighting development. Because LED lamps are energy-saving, environmentally friendly, small in size, and can improve lighting visibility, long service life, and thus reduce personnel maintenance time. Xi'an Xianyang International Airport statistics show that during the nighttime lights from April 22 to May 22, 2014, the airport LED taxiway center line lights are about 19.38% more energy-efficient than halogen lamps, and the LED taxiway side line lights are about 40.77 more than halogen lamps. %. However, the actual use of LED navigation lights shows that there is still a big gap with the theoretical situation. Guan Peng, general manager of ADB China, explained that the main reason is that the traditional chopper dimmer and isolation control restrict the energy-saving advantages of LED lamps. In order to achieve the best energy-saving effect of LED lamps, it is necessary to have matching. Dimming equipment. Although many people are optimistic about the development prospects of LED lamps, there are also some different voices. For example, LED lamps have no specific use standards in China, and the one-time procurement cost is high. These factors have affected the overall promotion of LED lamps. Why is there a dispute between LED lamps and halogen lamps in the field of airport navigation lighting? This has to start with the characteristics of the navigation light. The navigational light is the “body language†of the airport. It transmits information between the airport and the pilot through language symbols such as configuration, color, light intensity and effective range. The purpose of using the navigation light is to better guide the aircraft to safely land, especially at night and low cloud, low visibility conditions, the airport lighting system has played an irreplaceable role. In general, the airport has five requirements for the navigational lighting system. First, the sign is clear, enabling the flight area to be clearly distinguished from other aeronautical lights in non-flight areas. Second, the luminous efficiency is high and the light is soft. The lamp itself is required to have high luminous efficiency, sufficient brightness, clear light color, high resolution under certain visibility, and energy saving. Third, waterproof and heat dissipation performance is good. Fourth, it has a certain mechanical strength and has certain corrosion resistance and anti-collision capability. Fifth, the structure is simple, sturdy and durable, easy to disassemble and repair, the system is stable, the fault is less, and the flight can be guaranteed all the time and all the time, the price is relatively cheaper. Halogen luminaires are used in most airports because of their simple structure, low cost, and easy control and adjustment of brightness, but with short life and high energy consumption. Therefore, whether to use halogen lamps or LED lamps is an unanswerable question for the airport.
