LED lighting will help 'green airport' take off

Civil aviation Twelfth Five-Year Plan (2011-2015) Among them, the number of civil airports will reach 230, 83 new airports will be built in the central and western regions, and 101 airports will be rebuilt and expanded. Green lighting is an effective means to realize green airports, and green and intelligence are also one of the development directions of airports in the future. From Hong Kong Chek Lap Kok airport, Arlanda airport in Sweden, Manchester Airport in the United Kingdom, Christchurch Airport in New Zealand, Singapore Changi Airport, etc. , we can see that a series of airports are undergoing lighting renovation. LED lighting helps the green airport set sail. The airport is a huge energy consumption unit. Building a green airport is an inevitable choice for the development of the times. Among many energy-saving means and measures, the application of green and efficient lighting has become a major breakthrough for airports to save energy and reduce consumption and exert great effects. Tian Baohua, a professor at the Civil Aviation cadre management College, said. It is understood that the main incandescent filament bulbs currently used in most airports have a standard working life of several hundred to several thousand hours. In contrast, a well-designed LED lighting system can last for thousands of hours. The lighting system is the second largest consumer of electricity in the airport after the central air conditioning. Therefore, choose reasonable lighting schemes and suitable lamps in various regions, combining the intelligent lighting control system and making more use of natural light, it is one of the future development directions of green airports to carry out overall green and intelligent lighting transformation for airport terminal lighting. It is understood that at the beginning of the Chengdu airport project, it has been clarified that the indoor lighting of the new terminal will use LED lamps to reduce the cost of electricity in the airport operation. Construction and expansion began on 2009 and was officially put into use on July 28, 2012. The solar LED Green indoor lighting system, which is independently researched and developed by Anhui province and has independent intellectual property rights, is currently officially applied to the renovation and expansion project of Hefei Luogang airport waiting hall, the lighting system is currently a representative environmental protection and energy-saving lighting system in the world, with a terminal building area of 18000 square meters and an indoor height of 6- 9 M, ground lighting 200lx, color temperature 6000 K, excellent light distribution uniformity. The application of this system in Luogang Airport marks that Anhui province is at the forefront of the world in the field of solar energy and semiconductor lighting technology. The investigators made a literature review and investigated personal representatives who used LED airport lighting. Individuals from 22 airports and aviation agencies agreed to join the survey and complete all tasks (100 recovery rate). This report is the result of collecting the feeling and feedback information of LED airport lighting after use. The research results show that compared with traditional airport lighting technology, LED Airport lamps reduce energy consumption and maintenance requirements. LED airport lighting system has been applied for many years, and most of its application feedback in visibility and performance is positive. Through the improvement of technology, and FAA (Federal Aviation Administration) Efforts to promote the guiding role of led technology in airports have greatly improved its early compatibility problems. In the airport lighting system, most of the power systems were originally designed for incandescent lighting technology, so the LED airport lighting system is not compatible with this infrastructure. However, by replacing part of the power infrastructure and simply replacing incandescent lamps with LED lamps, the energy utilization rate and reliability can be greatly improved. Compared with traditional incandescent lamps, although the initial cost of using LED lamps is higher at present, the reduction of energy consumption and the saving of maintenance cost may bring returns to the initial high cost investment after several years. The maintenance requirements of LED airport lighting system are far lower than that of incandescent system, and the future research direction can be located on the economic impact in this area. Summary: due to the initial cost input of airport efficient lighting energy-saving renovation, the current cost of LED lamps is much higher than that of incandescent lamps, however, whether its increased service life, reduced energy consumption and reduced maintenance make up for the initial high investment is of great concern. By adopting a contract energy management model (EMC) The airport does not need to invest funds in the early stage. By saving electricity charges after upgrading the lighting system to pay for the renovation costs, it can alleviate the pressure of the airport's early investment, and at the same time help the civil aviation entities to reduce energy costs faster and in the long run, effectively implement energy conservation and emission reduction plans.
