High-power xenon lamps or opening a new future for energy-efficient lighting

According to reports, compared with the widely used LED lighting in the market, xenon lamps have their own advantages. At present, LED lighting, especially the high-power LED lighting technology used in road lighting, is still in the stage of technological innovation and development, and it is still not perfect in application. Xenon lamps have advantages in terms of high power, not only have their own independent intellectual property rights, but also have better cost control. At present, most people will think of the LED industry when it comes to energy saving and emission reduction in the lighting industry. However, there is still a group of people who have taken a different approach to make high-power xenon lamps an alternative to energy saving in the lighting industry. The nighttime lighting of the South Third Ring Road in Fuzhou City, Fujian Province has changed this year: the light has changed from reddish to brighter white, and the energy consumption has been greatly reduced. This is because the street lamp has been upgraded from a high-pressure sodium lamp to a xenon lamp. Caused by. Recently, the author learned from the high-power xenon lighting energy-saving technology conference that China's new high-power xenon lamp lighting source with independent intellectual property rights has been located in the whole city of Zhangping City, Fujian Province, Xushui County, Hebei Province, Chaoyang West Street and Fuzhou, Zhangjiakou City. The city's South Third Ring Road and other places have achieved good results in the demonstration of street lighting renovation. Taking the renovation of Zhangping City as an example, after replacing the high-pressure sodium lamp with high-power xenon street lamps, the energy saving rate is as high as 61.19%. In the past four years, it has saved 109.06 tons of standard coal and reduced 2721.14 tons of carbon dioxide emissions. In China, most of the lighting used in roads, factories, docks, airports and other places is dominated by old-fashioned high-pressure sodium lamps. This traditional lighting source has the disadvantages of high energy consumption, low luminous efficiency and short effective life. According to the statistics of the Urban Lighting Professional Committee of the China Municipal Engineering Association, as of 2015, there are more than 30 million street lamps in 1,065 cities nationwide, and traditional high-pressure sodium lamps with high power consumption and low brightness account for a high proportion. According to reports, compared with the widely used LED lighting in the market, xenon lamps have their own advantages. At present, LED lighting, especially the high-power LED lighting technology used in road lighting, is still in the stage of technological innovation and development, and it is still not perfect in application. Xenon lamps have advantages in terms of high power, not only have their own independent intellectual property rights, but also have better cost control, which provides new possibilities for energy conservation and environmental protection in urban and rural areas. According to Ning Qinsheng, vice president of Foshan Electrical Appliance Industry Association, the xenon lamp is actually a high-pressure gas discharge lamp. Its working principle is to fill the anti-ultraviolet crystal quartz glass tube with inert gas such as helium and iodide, and then pass through the stabilizer. The commercial power is instantaneously boosted to a pulse oscillating electric energy of about 23000 volts by frequency conversion, and the helium electrons in the quartz tube are excited by the high voltage oscillation to generate a jumping arc light between the two electrodes to complete the lighting process, and then the adaptive light tube is provided. The square wave voltage of the tube voltage with a pulse width period of 2.38 msec maintains the normal illumination of the xenon lamp. In the past, xenon lamps were mainly used in the transportation industry. Most of the xenon lamps on the market were used for low-power lighting such as automobiles and motorcycles. Today, the high-power xenon lamp developed by Ning Qinsheng and others can be used not only for outdoor and municipal road lighting, but also for industrial and mining enterprise lighting, tunnel lighting, commercial lighting, large stadium lighting, airport lighting, etc. According to the statistics of the National Bureau of Statistics, as of the end of 2014, the total number of street lamps included in government administration in China was 23019144盏, and the number of street lamps was much larger than the amount of street lamps added each year. The current market for the energy management model of Xenon lamp lighting technology supporting contract is mainly the current market for street lamps. Lin Bin, chairman of Guangdong Changsheng Lighting Technology Co., Ltd. said that in the current street lamp inventory market, 67% are high-pressure sodium lamps or high-energy products to be modified. If these high-energy road lighting street lamps are all modified with xenon lamps, It can save 81.7 billion KWh of electricity per year, save 33 million tons of standard coal per year, and reduce CO2 emissions by 85.8 million tons, which is equivalent to saving one year's power generation of the Three Gorges Dam. It is understood that the government also encourages the development of xenon lamps. The Beijing Municipal Development and Reform Commission has included the Xenon streetlights in the “Recommended Catalogue of Energy-saving and Low-carbon Technology Products in Beijing in 2013” ​​and the “Recommended Catalogue of Beijing 2012 Low-carbon Energy-saving Technology Application Cases”. In December 2015, the National Development and Reform Commission issued the “Key Catalogue of Key Energy-Saving and Low-Carbon Technologies” (2015), of which the 180th item included high-power xenon lighting technology in the promotion of key energy-saving and low-carbon technologies.
