Thinking about the application of water cube LED to the production enterprises

These days, the National Swimming Center "Water Cube" has become the focus of world attention. The Olympic Games were master Zhaijinduoyin here at the same time, it has raised a world record breaking climax.

However, you may not know, the "Water Cube" in the construction already broke a world record -- the landscape lighting using LED (semiconductor lighting products), the brightness, color and pattern of the outer surface of the water cube meets certain requirements, and the formation of certain scenes and mode. The combination of the cavity and LED lighting lighting application has created a precedent in the world.

Through the "Water Cube", more people know LED. At the moment, LED is taking steps to get out of the landscape into the ordinary family. However, due to the lack of national standards, LED had to slow down the pace. In the face of the broad market in the future, many of the LED production enterprises are extremely anxious: "we started late, but can run with it?"

Product promotion is very difficult

These days, the general manager of Zhejiang Pujiang Star Co., Xue Wenyan is mixed: joy is the Ministry of finance this year to implement the "efficient lighting products to promote financial subsidies to fund management Interim Measures" have been included in the directory LED, LED and her main road lamp production has also just been elected to the Zhejiang provincial government of Zhejiang province "energy-saving technologies and products promotion oriented directory"; the worry is that LED lighting products have yet to complete the national standard, it is difficult to promote the good stuff.

LED is the abbreviation of semiconductor lighting. It is based on semiconductor chips, relying on electron hole recombination luminescence, the conversion efficiency of electric energy into light energy up to 80%. It is understood that the LED energy consumption is only 10% of incandescent lamp, fluorescent lamp 50%; it uses solid package, service life can reach 100 thousand hours, is 10 times of the fluorescent lamp, incandescent lamp 100 times; it does not require the use of glass vacuum packaging, no toxic gas and mercury pollution.

"LED lighting technology will change our world once again. Xue Wenyan said. It is understood that in recent years, the world's three largest lighting industry giant - Ge, PHILPS and Rahm, have set up the semiconductor lighting company, developed countries have started LED national projects, hoping to seize the commanding heights of new industries.

In China, the LED industry has formed a relatively complete industrial chain. LED industry has gone through the purchase of devices, buy chips, buy epitaxial film stage, has been initially achieved the independent production of epitaxial wafers and chips. At this stage, the number of workers in the industry reached 50 Yuwanduo, more than and 20 research institutions and more than 4 thousand enterprises. 2006, China's LED industry output value reached 10 billion 550 million yuan, of which the output value of packaging industry reached $8 billion 750 million.

It is reported that the Shanghai Oriental Pearl TV Tower was originally LED lighting transformation, spent nearly 4 million yuan, but it turned out that the money is not white. According to the Oriental Engineering Department personnel, after the transformation of each month about Wanduoqian saving 5 kwh, a year to save the cost of about 500000 yuan. Today, the light is to save on the cost of electricity basically recovered the cost of modification. It is reported that tasted the sweetness, the Oriental Pearl is planning to replace all the lights inside the enterprise into a LED lamp.

As the world's largest producer of lighting appliances, the second largest exporter of China, in 2003 the establishment of the national LED lighting project coordination leading group, officially launched the national LED lighting project. But the reality is not optimistic. China's economically developed areas of the city about 70% users to enable energy-saving lamps, rural and underdeveloped areas still use incandescent lamp 80%, LED many people have never seen, heard not heard. Hangzhou Dianzi University senior engineer Luo said.

Why is it so energy-efficient LED promotion is difficult to have some experts believe that, with the LED lamp, many energy-saving products or energy-saving technology in the early stages of its promotion, are in the market cold. Promote the use of energy-saving products, of course, need to change the concept of the public, but it is more necessary to promote and support the government. But Luo friends think, LED promotion also need time. Although the Ministry of finance has been included in the promotion of LED products directory, but LED has not yet been a complete national standards, will greatly hinder its rapid access to millions of households. Foreign leading domestic non-standard

"One time, we went to a traffic management department to investigate the application of LED in traffic lights, when we received the researchers pointed to the traffic lights on the roof, said the company sent a sample of traffic lights. Less than a year, the indistinct flashing RGB color has been unable to make a resolution. "The thing that China Semiconductor Industry Association vice president of discrete devices branch length, deputy general manager of Beijing Changjiang electronics optoelectronics Co. Ltd. Ding Chenglong memories istana. He said: "a lot of Companies in their own product descriptions clearly printed on the life of 100 thousand hours, really do not know what is the experimental basis for the 100 thousand hour? So, we hope that the reliability of standard system can establish our LED as soon as possible. "

Due to the lack of reliability engineering standards, both sides often have differences on LED product performance and quality, also led to many engineering products, acceptance of dissent or even court cases.

According to Chinese laser optics and Optoelectronics Industry Association of optoelectronic devices branch secretary Peng Wanhua introduction, the main technology and industrial development in recent years, LED very rapidly, its application is expanding from the semiconductor lighting of the earliest and most widely used in LED display to the increasingly hot, the product variety, the urgent need to have the relevant technical standards and product standards. Especially in the field of semiconductor lighting, domestic and international organizations are actively organizing
