Beijing launches green lighting energy saving action plan

Beijing launches a green lighting energy-saving action plan. Beijing has upgraded an energy-saving project based on the determined urban lighting high-pole lights, single-lamp single-control, transformers, power distribution rooms, tunnel lights, and back-offices, and is guided by efficient and advanced scientific and technological concepts. . The urban lighting management center strengthens the introduction of green energy-saving project products, through the ** analysis of test results, economic analysis, potential difficulties, promotion plans, etc., to ensure that the application of new technologies achieves the desired effect. Based on the feedback data analysis of pilot energy-saving devices in the three power distribution rooms of Beijing’s Fangguyuan District, Chaoyangmen Bridge, and Jinsong Bridge, under normal operation, the voltage at the terminal of the lighting fixture should be maintained at% to% of the rated voltage, which is volts to volts. Volt. According to calculations, when the lamp voltage drops by %, the luminous flux decreases by% and the luminous efficiency decreases by %. Taking a one-watt high-pressure sodium lamp as an example, multiplying by the annual power saving rate %, one year can save kilowatt hours of electricity. Calculated at the average electricity price per kilowatt hour. Yuan, one year can save Yuan.　　 The dynamic lighting energy-saving device installed this time is more advanced in terms of technical principles than the previous SCR power saver and electromagnetic balance power saver. 'The dynamic energy-saving lighting device adopts power electronic technology to directly convert the mains power, realize high-frequency chopping voltage regulation and intelligent regulation, so that the voltage can be controlled accurately, with strong stability and no pollution, so as to achieve the purpose of saving electricity.' Fan Xing, the person in charge of the project, said. 'Take the commonly used high-pressure sodium lamp as an example. When its working voltage exceeds the rated value, the lamp life will be shortened quickly. When the working voltage is slightly lower than the rated voltage, the lamp life will be extended accordingly. But when the lamp voltage is less than% of the rated value The life of the lamp will decrease again. The dynamic energy-saving lighting device installed this time just combines these conditions, by reasonably controlling the working voltage of the street lamp, and ensuring the stepless stability during the adjustment process, confirming the stability of the inner arc of the bulb, and effectively extending the use of the lamp life.
