The high-tech LED industry research center spent half a year on the domestic “Ten Cities and Ten Thousand Miles†project, and the results were published in the high-tech observation column of the “High-tech LED†magazine in January 2010. The report is divided into concept articles, response articles, question articles, research articles, problem articles, demonstration articles, financial articles, deadlock articles, dissident articles, and conclusions. This website will publish the contents of the report one by one, so stay tuned. The following is the research article.
Fourth, research articles
Chairman Mao taught us that there is no right to speak without an investigation; Therefore, the high-tech LED industry research center began to visit the LED street lamp manufacturers for half a year, and conducted a survey around the following issues: What is the progress of the project? Is LED street lighting technology able to shoulder the heavy responsibility of “Ten Cities and Ten Thousand Cities� How high is the current localization of LED street lights? What is the current status of domestic LED street light companies? and many more. As long as the street light is not an LED street light, our investigation will continue.
How many lights were installed in the 21st city in 2009?
Among the 21 pilot cities in the “Ten Cities and Ten Thousand Cities†in 2009, the installed LED street lights (including tunnel lights) were approximately 222,000 baht. Among them, 35,000 in Weifang, 25,000 in Chongqing, 28,000 in Wuhan, and 15,000 in Yangzhou, the sum of the installed lights in the four cities is 103,000, accounting for nearly half of the total. Most cities in 2009 are still in the pilot phase of the project and are expected to be rolled out in large numbers in the next year.
How many lights will be installed in 2009-2011?
According to the relevant plans of each city, it is estimated that the number of LED street lights installed in 21 cities will reach 1.12 million 2009 in 2009-2011. At that time, many large cities began to install lights on a large scale. The cities with more lights were Shenzhen, Weifang, Shanghai, Tianjin, Chongqing, and Xi'an. The lights in these six cities reached 540,000, accounting for about half of the total. Cities such as Beijing, Guangzhou, Foshan, Suzhou, and Huizhou will also begin to install lights on a large scale. It is expected that the total installed capacity will reach 1.5 million.
What is the current status of localization?
In the specific plan of “Ten Cities and Ten Thousand Milesâ€, the state explicitly requested to increase the proportion of localization. The specific details are as follows: 1. In the pilot phase, the target ratio of localization of LED streetlight parts in 2009 is 60%; 2. In the demonstration stage (2010~2012), the target ratio of localization of LED streetlight parts is 70% (from media reports, official documents) Did not see the above statement).
The high-tech LED survey found that the localization rate of some products is close to 100%, such as heat dissipation, reflectors, lenses, etc. However, some products are less than 10% localized, such as light sources. The cost of light source accounts for more than 50% of the cost of street lamps.
1, the light source
Gaogong LED's survey of 40 companies found that domestic LED street lighting companies use almost no domestic chips, and chip makers with large market share include Cree, Philips Lumileds, Osram, Nichia and Japan and South Korea.
Cree tops the list with a 40% share. The company entered the Chinese market earlier and pre-emptively with few competitors. At the same time, the company is also the only foreign LED chip giant with packaging and epitaxial processing workshops in China. Philips Lumileds is a world-renowned professional high-power LED manufacturer with a large share of the global market. Many chip companies in Japan and South Korea focus on backlighting and display applications.
2, power drive
The survey found that many companies manufacture their own power drives, and some of them are outsourced. Some of them are products that are purchased from well-known foreign manufacturers in domestic branches. There are not many power sources purchased abroad. The localization ratio is 85%. Many self-produced power companies started out as electronic products, and there is a certain amount of technology accumulation in electronic technology. At present, the largest market share is Maoshuo's series of constant current and constant voltage LED high-power power supplies. Mingwei and Delta rank second and third. Some well-known power supply manufacturers such as Huntkey are also interested in LED power supplies.
3, other
The localization ratio of heat dissipation modules, lenses, reflectors, and casings is close to 100%, and most of them are self-produced or OEM. These products are relatively low in technical content.
LED street lamp manufacturers
1. Enterprise distribution
LED street light enterprises are distributed throughout the country. According to statistics from the high-tech LED network catalogue, enterprises are mainly concentrated in the Pearl River Delta, Yangtze River Delta, and Delta Triangle. The other seven LED industry bases also have a certain distribution.
2, the number of lights installed
In terms of the number of installed LED street lights (not limited to “Ten Cities and Ten Thousand Milesâ€), it is basically that enterprises that enter the market earlier have more lights installed. More lamps are installed in Shenzhen Deshida, Dongguan Qinshang and Weifang Zhongweiguang Electronics. According to the survey results of Gaogong LED, only 10% of enterprises with more than 10,000 lamps and nearly 70% of them under 5,000. (We only count the "large and medium-sized" street lighting companies in the LED industry, those who are "playing" LED street lights do not count)
