In the 12th Five-Year Plan of Civil Aviation (2011-2015), there will be 230 civil airports, 83 new airports in the central and western regions, and 101 airports will be expanded and expanded. Green lighting is an effective means to achieve green airports, and green and intelligent are also one of the future development directions of airports. From Hong Kong's Chek Lap Kok Airport, Sweden's Arlanda Airport, Manchester Airport, New Zealand's Christchurch Airport, Singapore's Changi Airport, etc., we have seen a series of famous airports undergoing lighting renovation. LED lighting helps the green airport to set off the airport is a huge energy unit. Building a green airport is an inevitable choice for the development of the times. Among the many energy-saving measures and measures, the application of green and efficient lighting has become a major breakthrough for the airport to save energy and reduce consumption. Tian Baohua, a professor at the Civil Aviation Cadre Management Institute, said. It is understood that the current incandescent filament bulbs used in most airports, the standard working life of incandescent lamps is about several hundred to several thousand hours. In contrast, well-designed LED lighting systems can last for thousands of hours. The lighting system at the airport is the second largest electricity consumer after the central air-conditioning. Therefore, select reasonable lighting schemes and suitable lamps in various areas, combine intelligent lighting control systems and use natural light for airport flights. The overall green and intelligent lighting renovation of the station building lighting is one of the future development directions of the green airport. It is understood that at the beginning of the Chengdu Airport project, it has been clear that the indoor lighting of the new terminal will use LED lamps to reduce the cost of electricity in airport operations. Construction began in 2009 and was officially put into use on July 28, 2012. The solar LED green indoor lighting system independently researched and developed by Anhui Province and officially owned by the company is officially used in the renovation and expansion project of the Luogang Airport Terminal in Hefei. The lighting system is currently the most representative environmentally-friendly and energy-saving lighting system in the world. The terminal area is 18,000 square meters, the indoor height is 6-9 meters, the ground lighting is 200lx, the color temperature is 6000K, and the light distribution is excellent. The application of the system at Luogang Airport marks Anhui's use in solar energy and semiconductor lighting technology in the forefront of the world. Investigators in the use of LED airport lighting and feedback results conducted a literature review and surveyed individual representatives who used LED airport lighting. Individuals from 22 airports and aviation agencies agreed to join the survey and complete the task in full (100 recovery rates). This report is the result of collecting the feelings and feedbacks of LED airport lighting after use. The results show that LED airport luminaires reduce energy consumption and maintenance requirements compared to traditional airport lighting technologies. LED airport lighting systems have been in use for many years, and most of the application feedback in terms of visibility and performance is positive. Through the advancement of technology and the efforts of the FAA (FAA) to promote the guiding role of LED technology in airports, the early compatibility problems have been greatly improved. In airport lighting systems, most of the power systems were originally designed for incandescent lighting technology, so LED airport lighting systems are not compatible with this infrastructure. However, by replacing part of the power infrastructure, simply replacing incandescent lamps with led lights can greatly improve energy efficiency and reliability. Compared with traditional incandescent lamps, although the current use of LED lamps requires higher initial costs, after several years, the reduction in energy consumption and the maintenance cost savings may bring returns to the initial high cost investment. The maintenance requirements for LED airport lighting systems are much lower than those for incandescent systems, and future research directions can pinpoint them to the economic impact of this. Summary: Due to the initial cost input of energy efficient renovation of airport efficient lighting, the current cost of LED lamps is much higher than that of incandescent lamps, but the increase in service life and the reduction of energy consumption and the reduction of maintenance make up for the initial high investment is a concern. By adopting the contract energy management model (EMC), the airport does not need to invest the funds in advance, and the electricity cost saved by the upgrade of the lighting system can be used to repay the transformation cost, which can alleviate the initial investment pressure of the airport and help the civil aviation entities to reduce energy more quickly and in the long run. Cost, effectively implement energy conservation and emission reduction plans.
