"Dynamic energy-saving lighting device will power directly'AC-AC transform with power electronic technology, 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 energy. "Lighting Center project manager. A new generation of dynamic energy-saving lighting device from the design concept, operation mode, operating procedures and other aspects of more intelligent and convenient.

In November 1st, the street distribution room is located in the four district of Fengtai District Xiluoyuan moved into the "new residents", the first dynamic energy-saving lighting device installed, marking the distribution room energy-saving device for City Lighting Management Center organized by the implementation of the installation work in full swing. It is reported that the installation of dynamic lighting energy saving device compared to the previous SCR (SCR) and electromagnetic balance of electrical appliances in the technical principles of advanced. "Dynamic energy-saving lighting device will power directly'AC-AC transform with power electronic technology, 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 energy. "Lighting Center project manager. A new generation of dynamic energy-saving lighting device from the design concept, operation mode, operating procedures and other aspects of more intelligent and convenient. Dynamic energy saving device installed in the configuration of the embedded intelligent microprocessor and advanced powerful, it can according to the demand for energy-saving lighting and lighting system to achieve zero power to full power within the scope of dynamic adjustment, at the same time it has flexible field programmable design, can adjust the working state of equipment, according to the abnormal situation in the scene, and make their own judgments, truly intelligent control, maximum energy saving. "We used high-pressure sodium lamp as an example, when its operating voltage exceeds the rated value, shorten lamp life soon, when its operating voltage is slightly lower than the rated voltage, the lamp life will be extended, but when the lamp voltage is lower than the rated value of 85%, and will decrease the life of lamps. Dynamic energy-saving lighting device, the installation is just to make up for these cases, effectively prolong the service life of the lamp through the working voltage will be reasonably control the lights, the key is to ensure the smooth process of regulating voltage continuously, to determine the stability of arc lamp. Transformer repair squad leader told reporters.

The new dynamic energy saving lighting device takes the lead of "green safety" as the idea, and in the aspect of safe operation, the equipment is added with the function of lighting protection. Energy saving equipment in the normal state, the main loop is closed; the assumption that lines for an unknown reason in the current situation, in the first time closed loop two, and equipment to detect the current moment; as in a short period of time to restore normal current loop two, disconnect the equipment operation, still according to the original plan; such as the current anomaly and the main open loop, the loop two over the line, in order to ensure the normal lighting. Through the feedback data of three power distribution room pilot energy-saving device Fangguyuan District, Chaoyang Bridge and the Chaoyang Bridge, can realize the normal operation, lighting voltage should be maintained at the rated voltage of 90% ~ 105%, which is 198V - 231V. According to the relevant research shows that high pressure sodium lamp stability, power supply voltage suddenly dropped to 190V or even 180V, high pressure sodium lamp will not go out. If you take a slow smooth voltage regulation can be reduced to a lower voltage. In the process of high voltage sodium lamp voltage adjustment, the power consumption of the light source changes accordingly. In the process of reducing pressure, the light flux of the light source decreases slightly faster than the power consumption, so the light efficiency of the light source is reduced. It can be seen that when the lamp voltage drops 9%, the luminous flux is reduced by 25%, and the luminous efficiency is reduced by 5%.

According to the Ministry of housing "" 12th Five-Year "city green lighting plan notice" city [2011]178 documentation requirements, to the end of 2010 as the base, to the "12th Five-Year" period, city lighting energy saving rate of 15%; evaluation of road lighting energy saving rate of not less than 70%; the application rate of City Lighting of high light efficiency, long life light source not less than 90%. The mission of the center of lighting, lamp, single lamp control, transformer, power distribution room, tunnel lights, the upgrade six energy-saving projects as a whole, with high efficiency, advanced science and technology philosophy as a guide, strengthen the green energy-saving project product introduction, test results of economic analysis, potential difficulties, promotion plan etc. to conduct a comprehensive analysis, in order to ensure the application of new technology in the ideal effect. Next, install lamps distribution room dynamic energy-saving lighting will be in full swing, the lighting center will make regular data records and compared the energy saving device in operation, to ensure the safety, reliability and energy efficiency "to meet the requirements, in order to create a green city lighting and lay a solid foundation.
