Recently, the civil aviation 2 scientific research and development centres for the ministry of science and technology research institutes of technology development special fund project "LED energy saving light system through experts acceptance. The experts agreed that the project technical scheme is advanced, the product has good energy saving effect, good completed all tasks, and suggested to further speed up the popularization and application in civil airport. The project research results, will be for our country to build green low carbon aviation, civil aviation airport provides favorable technical support for energy conservation and emissions reduction.

Under the ministry of science and technology special funds to support, the civil aviation scientific research center in LED by two energy-saving light technology fruits have been achieved. Research and development of scientific research center of energy-saving LED light system, compatible with the old and new navigational lighting system of the power supply system. System can be according to the traditional A ~ 6.6 A 2.8 5 dimmer way to work, can also be done 2 A low current power supply 5 accurate dimmer. In 2 a working mode, the system can significantly reduce the loss of circuit, realize the work with LED lights, low current characteristics of the best match, the energy saving effect is greatly superior to the single lamp replacement type LED light system.

At present, the related research has entered the stage of industrialization promotion, the civil aviation of the eight kinds of LED lamps and lanterns of navigation and the sine wave frequency constant current dimmer has issued by civil aviation administration of civil airport approval certificate of special equipment and has been in lanzhou zhongchuan airport taxiway successful application in the reconstruction project of lamps and lanterns.
