“Energy conservation must start with 'on-demand lighting', especially in public buildings such as underground garages, corridors, stairwells, etc. There are significant differences between effective lighting time and actual lighting time in these places, using intelligent LED lights equipped with radar microwave technology. It can play the dimming function of 'people come to light, people go dark,' can provide lighting, but also achieve good energy-saving effect." In the recent "public buildings efficient lighting energy-saving technology application promotion meeting", Yan Shukui, vice chairman of the China Lighting Society, said.
The “Application Promotion Conference for Efficient Lighting and Power Saving Technology for Public Buildings†was hosted by the Beijing Energy Conservation and Environmental Protection Center. It is a sub-project of “China's phasing out incandescent lamps and accelerating the promotion of energy-saving lamps†developed by the National Development and Reform Commission and the United Nations Development Program.
According to reports, in addition to the advantages of low energy consumption, no pollution, no mercury, no screen flash, long life, strong controllability is the distinctive feature that LED light source is different from traditional light source. Therefore, it can be closely integrated with the “on-demand lighting†environmental protection concept, and it has excellent power saving effect in the promotion and application of public building areas, and has strong competitiveness. The Hebei Provincial Department of Education carried out energy-saving renovation of the lighting in the public areas of its office buildings, replacing the original straight-tube fluorescent lamps and grille lamps with 661ç›LED intelligent lamps. Through the whole process of Hebei Energy Conservation Monitoring and Monitoring Center, the power saving rate can reach 90.3%, the annual energy saving is 127,600 kWh, the annual electricity saving fee is 108,500 yuan, equivalent to saving 42.5 tons of standard coal, reducing carbon dioxide emissions by 127.3 tons, project investment recovery. The period is 2 years.
