Year of life survey: ten cities in front of the wind and waves in the wind (research paper)

Research articles

Chairman Mao taught us: no investigation no right to speak; the media do not recklessly. Therefore, we started up to six months of LED street lamp manufacturers visited, around the following issues carried out an investigation: the progress of the project? LED street lighting technology has been able to bear the "Ten City million" task? How high is the localization of the current LED street lamps? What is the status of domestic LED street lamp enterprises? Wait As long as the street lamp is not a LED street lamp, our investigation will continue.

How many lights were installed in 21 cities in 2009?

The 21 pilot city 2009 "ten city lights", LED lamps have been installed (including tunnel lamp) is about 222 thousand light. Among them, Weifang 35 thousand, Chongqing, Wuhan, 28 thousand, the city of Yangzhou, the sum of the installed capacity of the lights in the four cities was 103 thousand, accounting for nearly half of the total amount of the amount of the amount of the amount of light, such as:. Most cities in 2009 is still in the pilot phase of the project, is expected to be released next year.

How many lights will be installed in 2009-2011?

In accordance with the relevant planning of the city, is expected to 2009-2011 21 city LED street lamp installation number will reach 1 million 120 thousand. In 2011, a lot of big cities began to install lights on a large scale. The cities with more lights include Shenzhen, Weifang, Shanghai, Tianjin, Chongqing and so on. In the six cities, the number of lamps is up to 540 thousand, accounting for about half of the total. By then, Beijing, Guangzhou, Foshan, Suzhou, Huizhou and other cities outside the 21 cities will also begin large-scale installation of lights, is expected to total installed capacity is expected to reach 1 million 500 thousand.

Localization of the proportion of the status quo?

In the Ten City million light in the specific planning, the state explicitly requested to improve the proportion of localization. The details are: 1, the pilot phase, 2009 LED lamp parts localization ratio target of 60%; 2, the demonstration stage (2010~2012), LED lamp parts localization ratio target of 70% (from media reports, the official documents did not see the above statement).

LED survey found that the proportion of domestic production of some products close to 100%, such as heat, reflective cups, lenses, etc.. But there are also part of the domestic product ratio of less than 10%, such as the light source. The cost of light source accounted for more than 50% of street lamps.

1, light source

The survey found 40 companies of high LED, domestic enterprises LED street almost do not use homemade chips, a larger market share in the chip maker CREE, PHILPS Lumileds, OSRAM, Japan and South Korea and Taiwan manufacturers nichia.

Cree topped the list with about 40% of the shares, the company entered the Chinese market earlier, in the case of almost no competitors. At the same time, the company is also the only one in China with packaging and epitaxial processing of foreign LED chip giant. PHILPS Lumileds is the world's leading professional manufacturer of high-power LED, a large share in the global market. Japan and South Korea's many chip companies are focused on the backlight and display applications.

2, power driven

The survey found that many companies to create their own power supply, there are some companies outsourcing, which is part of the procurement of well-known foreign manufacturers in the domestic branch of the company's products, procurement of foreign power supply is not much. Localization ratio of 85%. A lot of self generated power companies are doing electronic products started, in this piece of electronic technology has a certain accumulation of technology. At present, accounting for the largest share of the market is a series of mosopower constant current constant voltage LED power supply, meanwell, delta ranked second and third. Some well-known manufacturers such as Huntkey power, are also interested in LED power supply.

3, other

Heat dissipation module, lens, reflector cup, shell and other products localization rate is close to 100%, and most of the self-produced or OEM. These products are relatively low technical content.

LED street lamp manufacturers

1, enterprise distribution

LED street lighting enterprises are distributed throughout the country, according to the statistics of the high tech LED network catalog shows that enterprises are mainly concentrated in the Pearl River Delta, Yangtze River Delta, Fujian Delta and other regions, the other seven LED industrial base also has a certain distribution.

2, the number of lights installed

In the number of LED street lamps have been installed (not limited to the Ten City million), is basically the market to enter the early enterprise installed more light. Lamp is more micro electronics Shenzhen deshida, Dongguan and Weifang in the ground. According to the results of the investigation of high tech LED, the number of lights installed more than ten thousand of enterprises accounted for only about 10%, less than five thousand of nearly 70%. "We only on the LED industry in the" large and medium-sized "street lamp enterprises statistics, those who are" playing "LED street light companies do not
