LED lamp PK halogen lamp who can lead the field of navigation lights?

Recently, Xi'an Xianyang International Airport and has 67 years of experience in the production of airfield lighting products will be Eddie grams Airport Navigation Technology Co. Ltd. (ADB), became the first domestic on the taxiway with large LED airfield lighting lamps airport.

At present, most of the domestic airport use halogen navigation lights. But some people in the industry believe that LED lighting is the future of the development of navigation lights. Because the LED lamp has the advantages of energy saving, environmental protection, small size, and can improve the visibility of light, long service life, thereby reducing the maintenance time and other advantages. Xi'an Xianyang International Airport statistics show that in April 22, 2014 -5 month 22 days with lights during the night, the airport LED taxiway centerline lights are about 19.38% energy-saving halogen lamps, LED taxiway edge lights with halogen lamp about 40.77% energy saving.

However, the actual use of LED to help light lamps and lanterns data show that there is still a gap between the theoretical situation. The general manager of ADB Chinese Guan Peng explains, is mainly because the traditional chopper dimmer and isolation transformer restricts the LED lamps energy saving advantages, to achieve the best energy saving effect of LED lamp dimming equipment, also need to have matching.

Although many people optimistic about the prospects for the development of LED lamps, but there are some different voices. For example, LED lamps in the country there is no specific standard of use, one-time purchase cost is high, these factors have affected the comprehensive promotion of LED lamps.

Why in the field of airport navigation lighting will have LED lamps and halogen lamps dispute? This also has to speak from the characteristics of the navigation light. The navigation light is the "body language" of the airport, which transmits information between the airport and the pilot through the language symbols, such as configuration, color, light intensity, effective range and so on. The use of light to better guide the safety of aircraft landing flight, especially at night and low clouds, low visibility conditions, airport lighting system is playing an irreplaceable role.

In general, there are five aspects of the airport's requirements for the lighting system. First, the mark is obvious, can make the flight area is obviously different from other non flight area of aviation lights. Second, high luminous efficiency, soft light. Requirements of the lamp itself has a high luminous efficiency, sufficient brightness, light color, can have a higher visibility in a certain visibility, and save energy. Third, waterproof and good heat dissipation. Fourth, there is a certain degree of mechanical strength, corrosion resistance and a certain ability to resist. Fifth, the structure is simple, durable, easy disassembly and maintenance, the system is stable, less trouble, all-weather all time and space to protect the flight, the price is relatively cheap.

Most of the airport use halogen lamps, because of its simple structure, low cost, and easy to control and adjust the brightness, but short life, large energy consumption. Therefore, in the end the use of halogen lamps or LED lamps, for the airport, it is a difficult question to answer.
