"Our local government recently also want to install one or two street lights in the streets of the LED, the brightness in the end how ah? "March 2nd Guangzhou Pazhou Exhibition Hall, from Hunan Hengyang lo a sweat water station in Shenzhen unilumin booth, the receptionist asked some technical problems to the field of LED street lamp.

Full of expectations, Mr. Luo may not know, the domestic LED lighting is not as mature as his expectations. Last year, the Ministry of science and technology to start the Ten City million project triggered a frenzy of LED lighting, but this does not solve the problem of technology.

The first two days, the Guangzhou Municipal Science and Technology Bureau revealed that before the Guangzhou Asian Games, Guangzhou road LED Street coverage will reach 40%, an increase of 140 thousand LED street lights. China has become the world's LED street test site. High LED CEO Zhang Xiaofei March 1st on the first financial daily reporters.

But in fact, Zhang Xiaofei stressed that due to last year's Ten City million pilot cities to reflect the problem, it can be said that there is no one LED street lamp companies have really clearance, a comprehensive solution to all the problems of LED street lamps. Because LED lighting technology is not mature enough, in Europe and other developed countries, the LED is only used for street community, or in the trunk road small pilot, "not so recently added new demonstration city, a large-scale promotion of LED street lamp".

LED street lamp maturity

"TCL's LED street lamps have pilot projects in Wuhan and Huizhou. A TCL lighting engineer pointed out that the current high power LED lighting TCL lighting strategy is only tracking and technical reserves, the main reason is because the LED lamp technology maturity is not enough, the heat dissipation of LED street lamp, packaging and other technical problems have not been completely broken.

A lot of LED road lighting decay reached 30%, which means that the use of LED street lights after 18 months, only about the new brightness of about 60%. The heat problem directly leads to a life expectancy of 100 thousand hours from the theoretical value, shortened to 30 thousand hours. "

However, LED street lamp product technology maturity and quality problems and local government investment in LED lighting boom has formed a strong contrast.

According to the national Ministry of science and technology, ten city million at the end of the year by the end of the idea, that is, select the 10 cities, each city to promote the application of LED lighting 10 thousand. In April last year, the Ministry of science and technology clearly 21 cities to participate in the pilot project of the "ten cities".

LED lighting boom set off. Zhang Xiaofei pointed out that last year to apply for a number of cities to do demonstration cities, regardless of whether or not the local LED companies have the basic conditions. High engineering LED statistics show that last year, a total of 21 pilot cities installed a total of 222 thousand LED street lights.

This year is expected to add at least 400 thousand. "Zhang Xiaofei pointed out that due to the lack of standards, government procurement to local enterprises, make a lot of immature LED lamp products into the market," We conducted a survey of 40 domestic LED lamp enterprises, showed that nearly 1/3 of the companies began producing LED lamp in a year. "

LED street light is too dark, a section of lights out. This time to become a secret LED lighting industry. LED street leading enterprises KingSun chairman Li Xuliang also revealed that some small manufacturers in Zhuhai, Dongguan and Shenzhen pilot did have the lights.

From March to July last year, the city of Shenzhen organized the most complete LED street lamp test, 27 street lamps involved in the test. There is no standard who is qualified products, but the proportion of good products is not high. Wu Chunhai, director of the planning and Design Office of Shenzhen environmental management center, said, compared to the traditional street lights, LED street lamps in the small streets of the obvious advantages, but there is no advantage in the urban trunk road. Therefore, this year, Shenzhen new LED street lamp is still locked in 2000 to 3000.

Zhang Xiaofei made a study of Shenzhen test results that the test on a total of 1200 hours, but most of the products of the decay reaches more than 10 percent, obviously can not meet the 50 thousand hour time less than 30% of the target, indicating that the technology is not mature, at least not for the main road.

LED enterprise embarrassment

In addition to the embarrassment of immature technology, LED Street business this year will also face how to get new orders, as well as the way to get new orders.

Based on the conclusions of the pilot, some local governments have slowed down the pace. This year, Weifang will add 7000 LED street lamp, has been installed before the 27 thousand and 600. "Weifang City streetlights Management Office official pointed out that the Weifang pre pilot reflects two aspects, one is the traditional lighting LED lighting power supply facilities lags behind the pace, two is the lack of standards, to judge whether the qualified LED street.

The Baoding Street Management Department official also said that due to the LED street lamp is not up to standard, the main street lamps in Baoding will be mainly based on sodium lamps, small streets and neighborhoods will use LED street lamp.

"We're groping, too. Li Xuliang said in a telephone interview yesterday, said, this year's situation is not clear, there is no new orders. "

As of the end of 2009, KingSun has installed 150 thousand LED road lamps, covering 35 city nationwide. LED street lamp as a new thing, will inevitably lead to a lot of controversy. Though not say LED lamps have been perfect, but in order to eliminate local government concerns, KingSun the project will generally request the insurance company guarantee, guarantee a lifespan of 5 years, of course, not every LED lamp products are willing to guarantee insurance company. Li Xuliang said.

In fact, this year the biggest embarrassment LED Street companies should be no rice pot".
