Expensive to change LED street lamp promotion by many questions

LED Street lamp has many advantages, the development of the boom can not ignore its shortcomings in the description of the LED industry, many people seem to have seen the future of a bright ——— "the fastest in 2015, led in China's market share of lighting will reach 20%, driving the industry scale up to 500 billion yuan,　　China will enter the global LED lighting market before the top three.　　500 billion yuan of output value is fragrant pastry? May 2009, the Ministry of Science and Technology organization by the LED in the municipal lighting application demonstration project as the carrier, selected 10 cities, each city to promote the promotion of more than 10,000 led function lighting, this plan is called "Ten City Million."　　Since then to join the plan of the city increasing, but today, the promotion of LED street lights have heard a lot of questioning.　　Yangcheng Evening News reporter Li Xiaoli 42 city participated in "Ten Cities Million" 2010, November, Guangzhou Asian Games, whether it is the opening ceremony or the closing ceremony, "Light feast" technology surprised four. Obviously, the Guangzhou Asian Games will be led to the peak.　　For a time, "green", "Energy saving", "High-tech" and other praise words, almost become synonymous with LED, everywhere are shining led light. "From the beginning of last year, the domestic led market suddenly unusually optimistic, at home and abroad investment and mergers and acquisitions integrated upstream and downstream enterprise process acceleration, state-owned capital, private capital, etc. have entered." "In the recently held Guangzhou International Lighting Exhibition Press conference, a person in the line quietly said:" Traditional lighting business is to see this is not fully developed the treasure, a time of various types of LED lighting products flooded the market. "This is the 2009 Ministry of Science and Technology promulgated" Ten Cities million "after another round of led investment trendy. According to the plan of 2 years ago, the target of "Ten cities million" semiconductor lighting Application project is: By 2011 in the pilot city for municipal engineering application 6 million LED lighting products, direct domestic demand 15 billion yuan; by 2015, led into the general lighting market 30%.　　In fact, the country now does not stop the "ten cities", according to the end of 2010, there are already 42 cities including Guangzhou included in the plan. Together to change the street lamp "unscientific" If you ask me the same question now, I still hold the same opinion ——— to promote the LED lights must be prudent, can not head fever!　　"Public to the LED street light water, is from the southern power grid of the NPC representative of Xin Waterfall, in the two sessions, he once again to the Yangcheng Evening news reporters reiterated" can not be too hasty. "At present, various cities in China to promote LED street lamp formed a trend." Everyone thought it was a new energy-saving technology, "symplectic waterfall analysis points out," in the same lighting intensity, led streetlights are not more energy-efficient than high-pressure sodium lamps. Coupled with the current various manufacturers LED lamp specifications vary greatly, once maintenance replacement will be very troublesome. Because it's not as fully standardised as a high-pressure sodium lamp, it's easy to buy replacements when the original bulb breaks. "Xin Waterfall bluntly:" In fact, as far as I know, these are foreignSome led patented technology companies in the promotion of lobbying, only they mastered the core of the LED technology, if our domestic large-scale promotion, the most profitable is their. "Xin Waterfall is not the first to stop the LED street light industry personage. Chen Yanseng, director of China Lighting Association in Guangzhou International Lighting Exhibition Press conference, repeatedly reminded the "overheating": "LED application is very wide, there is a TV monitor rear projection, there are building exterior wall landscape lights, as well as car lighting brake lights and so on." But for this piece of street lighting, we need to know it scientifically. "As an expert in industry associations, Chen Yanseng The worry:" In street lighting, it is now used mainly in high-pressure sodium and high-pressure mercury. High-pressure mercury-containing mercury is not environmentally friendly and can be replaced. But high pressure sodium itself is green, energy-efficient, high efficiency, do not need to be replaced. Now many cities in order to develop the LED industry, is always a swarm of original street lights replaced by led streetlights, which in itself is unscientific.　　"High prices are due to the standard does not unify the Chen Yanseng of the fear is not unreasonable."　　All along, led market difficult to promote the main reason is that LED lighting products are too expensive. Kunming against the installation of LED streetlights. Last September, the city used data to prove the price problem ——— in Kunming, the installation of street lamp cost is 15,000 yuan/A, including the value of about 2000 yuan of lighting equipment, as well as cable, installation, labor and other costs.　　and an LED street lamp, a single lighting equipment needs 5000-7000 yuan, all installed down about 1.8-20,000 yuan. Kunming case, just say the LED street lamp installation costs high. However, there is still a large amount of account to be calculated ——— LED street lamp cost high, maintenance of expensive is the fact that the lighting industry is recognized ——— LED lights in addition to the lamp, there are poles and chips, a set of prices also need more than 2000 yuan. "The biggest headache is maintenance because there is no uniform LED light standard." Manufacturers of their own production, self-reliance standards. "A person in the industry said," some LED lamp caps broken, to find manufacturers to change. However, manufacturers do not necessarily produce this model of the street lamp, had to replace the lamp pole together. If the heat is not good, it ' Yiguoduan '. "" The Swarm of "development worries more" everyone swarm development led, is staring at the ' incandescent elimination ' plan.　　"Chen Yanseng analysis points out that in March 2007, the European Commission proposed legislation to phase out incandescent lamps by the end of 2012, and China also plans to eliminate incandescent bulbs 2013 years ago," but eliminating incandescent lamps does not mean replacing them with LEDs. The swarm development not only attracts the enterprises without any experience of producing lighting products, but also attracts the drastic transformation of traditional lighting enterprises. "The threshold of the industry is very low, the current domestic LED lighting production enterprises more than 3,000, but 70% of them concentrated in the downstream integration of the application link." "An industry insider who declined to be named said: According to the LED production process, led lineIndustry can be divided into upstream epitaxial film production, midstream chip manufacturing, downstream chip packaging three parts, of which, upstream and midstream technical content is high, capital investment density, competitive but can account for the entire industry 70% profit, "Now, high-end chip, more than 80% from foreign or Taiwan region; Downstream package profit only 10%-20　　% or so, but most of the LED enterprises in our country are concentrated. "LED lighting currently does not have a unified national standard, the market weeding phenomenon is serious." Some shanzhai companies, rent a small factory, hire a few workers, bought accessories is an LED factory. He also pointed out that, "at present, LED lighting energy-saving subsidies are all the cities themselves, so generally biased to subsidize the local led enterprises." is already a public secret in the industry. "More importantly, led explosion-type growth, bringing the detection technology and standard-setting, and other common problems, the current product lacks a complete industry standard standards, quality and bad."
