LED street light: accelerate the promotion of technology promotion

According to statistics, in 2011, the total output of China's LED street lamps (excluding tunnel lights) was approximately 680,000 baht, an increase of 58% year-on-year, of which domestic LED street lamps installed 530,000 baht, an increase of 51% year-on-year. It is estimated that the total output of LED street lamps in China will reach 1.22 million baht in 2012, an increase of 79% over the same period of last year, and domestic installations will reach 850,000 baht, an increase of 60% year-on-year.

The level of technology has improved. In 2011, the installed capacity of LED street lamps in China was 530,000. Compared with the previous two years, there has been a significant increase in technology and performance. In the past few years, due to problems such as unreasonable drive power supply and luminaire design, LED street lamps have suffered from poor light, color drift, and even dead lights. Some newly installed lights were replaced in less than half a month, seriously affecting public trust in LED street lights. Since last year, the acceptance of LED street lamps has been greatly improved by the public. LED street lamp driving power has greatly improved its performance. Domestic LED power supply manufacturers have increased the research and development of LED outdoor drive power. After two years of development, LED outdoor drive power technology has made a major breakthrough. High-reliability, ultra-high efficiency, long life, superior features, intelligent control and other new products continue to emerge. The problem of LED driver power supply is no longer the bottleneck for the promotion of LED street lamps. However, at present, some technical indicators still have deficiencies, and prices are still at a relatively high level relative to traditional light sources.

Expansion of the scope of expansion In May 2011, the second batch of 16 “Ten Cities and Ten Thousand Cities” pilot cities were approved, demonstrating the government’s determination in LED promotion. The promotion model has gradually evolved from demonstration promotion to universal promotion. The survey found that not only is the pilot city of “Ten Cities and Ten Thousand Cities”, but other non-pilot cities have already started trials of LED street lights, or they have formulated LED street lighting promotion plans, but they are still very cautious about the speed of promotion. After all, LED street light standards are still missing so far, the market is chaotic, and the risk of blind promotion is too high.

In the LED street lighting promotion model, the EMC model is considered to be the most ideal model. However, there are still difficulties in the application of the EMC model in China, and many companies still do not recognize it. The difficulty in the application of the EMC model is mainly due to the fact that the payment period is too long. From the perspective of the enterprise, the maintenance cost in the later period is too high. EMC's input costs are too high and the risks are too high. Another popularization model is the BOT model, which is still in its infancy in China.

From the perspective of enterprises, the major LED street lighting companies in the country include Jiangsu Shifu, Dajin Dongfang, Dongguan Qinqin, Zhongwei Optoelectronics, Xiamen Xinda, and Zhejiang Jingri. From the project point of view, the major projects of LED street lamps in 2011 include Dongguan Qinshang Shenzhen Jihe Expressway, Nanguang Expressway, Longda Expressway, Yanba Expressway Project, Philips Guizhou Huaxi Avenue Project, and Dazhou East Zhengzhou Shenzhou Road Project. Dongguan Qinshang Shenzhen Expressway LED street lamp project is one of the large LED street lamp projects in 2011. The entire project has more than 8,800 LED street lamps installed.

From the point of view of urban promotion, Weifang, Guangzhou, Shenzhen, and Chongqing are fast-growing cities for LED street lamps.

This year, the output is expected to reach 1.22 million. In 2012, the acceptance of LED street lights was further enhanced. Local governments all accelerated the promotion of LED street lamps. Chongqing plans to install 50,000 LED street lights within two years; Henan Zhengzhou plans to promote the installation of 78,000 LED street lights before 2015; Jiangsu Yangzhou plans to use 100% of secondary road lighting and residential lighting using LED lighting products by 2015; 30% of cities The main road lighting uses LED lighting products, and the demand for LED street lamps reaches 50,000 baht; Hainan province plans to replace 210,000 street lamps in the province with LED street lamps by the end of 2012; Guangdong Zhongshan has installed 1.6 LED street lamps in 2011 in all towns. Wan Duoyu plans to have a total of 50,000 LED street lamps by the end of 2012; Foshan also strives to reach 120,000 LED street lamps by 2012. Not only in China, but also in many foreign countries, energy saving and emission reduction plans have been started in 2012. The promotion of LED street lamps has become one of the major measures for energy-saving and emission reduction plans.

It is estimated that in 2012, the total output of LED street lamps in China will reach 1.22 million baht, a year-on-year increase of 79%. As the most critical component of LED street lamps, LED street lamp driving power will also develop rapidly in 2012 with the rapid promotion of LED street lamps. It will be an opportunity for LED street lamp driving power companies that have the support of technology and financial strength. .
