Beijing green lighting energy conservation action plan

According to the Ministry of housing "" 12th Five-Year "city green lighting plan notice" requirements, to the end of 2010 as the base, to the "12th Five-Year" period, city lighting saving rate reached 15%, evaluation of energy-saving lighting the road up to the standard rate of less than 70%, the rate of city lighting application of high light efficiency, long-life light source of not less than 90%. Beijing City upgrade 6 energy-saving projects according to city lighting lamp, the single lamp control, transformer, power distribution room, tunnel lights, background.

November 1st, Beijing, Fengtai District, the four district of the park street lamp room into the new tenants - the first dynamic energy-saving lighting device located here. The same day, according to the green lighting energy conservation action plan launched in Beijing, the national network of urban lighting management center in the implementation of the distribution room energy saving installation work in full swing. According to the Ministry of housing "" 12th Five-Year "city green lighting plan notice" requirements, to the end of 2010 as the base, to the "12th Five-Year" period, city lighting saving rate reached 15%, evaluation of energy-saving lighting the road up to the standard rate of less than 70%, the rate of city lighting application of high light efficiency, long-life light source of not less than 90%. Beijing City upgrade 6 energy-saving projects according to city lighting lamp, the single lamp control, transformer, power distribution room, tunnel lights, background, with high efficiency and advanced technology concepts as a guide for the overall advancement.

Urban lighting management center to strengthen the introduction of green energy projects, through the test results, economic analysis, potential difficulties, such as the promotion of a comprehensive program to ensure that the application of new technology to achieve the desired results. From the analysis of the feedback data of Beijing City, Fangguyuan District, Chaoyang Bridge, Jinsong bridge three distribution room pilot energy-saving device, under normal operating conditions, lighting voltage should be maintained at the rated voltage of 90% to 105%, which is 198 volts to 231 volts. It is estimated that when the lamp voltage is decreased by 9%, the luminous flux is reduced by 25%, and the luminous efficiency is reduced by 5%. To work with a 400 Watt high-pressure sodium lamp 4200 hours a year as an example, multiplied by the power saving rate of 15%, a year can save 252 kwh of electricity. According to the electricity price of 0.71 yuan per kilowatt hour calculation, a year can save $180.

The installation of dynamic lighting energy saving device compared to the previous silicon controlled (SCR) and electromagnetic balance of electrical equipment in the technical principle of more advanced. "Dynamic energy-saving lighting device using power electronic technology, the electric direct conversion, high frequency chopper and intelligent control, the voltage can be accurately controlled, strong stability and no pollution, so as to achieve the purpose of saving electricity. The project leader fan Xing said. "Taking the commonly used high pressure sodium lamp as an example, when the working voltage exceeds the rated value, the life of the lamp is shortened quickly. When the working voltage is slightly lower than the rated voltage, the lamp life will be prolonged. However, when the lamp voltage is lower than the rated value of 85%, the lamp life will decline. Dynamic energy-saving lighting device, the installation is taking these circumstances, through reasonable working voltage control the lights, and in the process of adjustment to ensure the continuously stable, determined in the bulb arc stability, prolong the service life of a lamp.
