No doubt: LEDs are causing lighting**

LED will have no doubt about lighting revolution. Although there are many products on the market, it is imperative that the key technologies have yet to be broken through. The “resulting in blossoming” is the status quo in the industry. There is still a long way to go before LED lighting products actually enter the market. Whether it is the National Semiconductor Lighting Project, or the “Ten Thousand Cities” demonstration project, and the Industrial Technology Innovation Strategic Alliance, the purpose is to promote the development of this new industry and win the competition in the preemptive position—

The prospects are not just a lamp to replace another lamp. The LED has much room for development in China. The answer can be found in the following three groups cited by Qiu Baoxing, Deputy Minister of Housing and Urban-Rural Development: First, there are 657 cities in China. In the municipal lighting, there are only 17.74 million miles of municipal road lamps, which will increase by about 1.5 million tons per year. Secondly, China will build 2.1 billion square meters of new buildings each year, and there will be at least 20 lamps in each building unit. During the period, 36 million sets of affordable housing will have the potential to use 500 million to 600 million lamps, and these two architectural lightings alone can save more than 10 billion kilowatts of electricity if 30% use LED lighting. Nearly 20 million households lack electricity and electricity. If these households use solar energy and LED integration to replace the power supply of the large grid, they can save more than 50 billion kWh.

"Only from these three aspects, LED has an extremely broad market. LED is a main battlefield for energy-saving." Qiu Baoxing said. The layout of our country in this industry has already begun. The Ministry of Science and Technology launched the "National Semiconductor Lighting Project" in 2003. Over the past 10 years, through continuous investment in science and technology projects such as the 863 Program and support plans, the level of semiconductor lighting technology has significantly improved, forming upstream material and chip preparation, midstream device packaging, and downstream Integrated application of a more complete innovation chain and industry chain. The complete industrial chain has also become China's LED industry advantage.

"Semiconductor lighting has brought us not only a single lamp to replace another lamp," said Wan Gang, vice chairman of the National Committee of the Chinese People's Political Consultative Conference and Minister of Science and Technology. "LEDs have a wide range of applications and will bring a lot to our lives and cities. influences."

China's current incandescent lamps exceed 1 billion baht, and lighting energy consumption accounts for about 1/6 of the total power consumption. With the publication of the “phasing out incandescent light roadmap”, the state will issue a subsidy policy to promote the development of LED lighting applications. It is estimated that in 2015, China's LED lighting market will reach nearly 100 billion US dollars. Although the current development of the LED industry is not easy, but a huge lighting business opportunities, it has attracted capital from all walks of life with unprecedented speed.

The demonstration is not only for 37 cities and 400 million kWh electricity. By 2010, over 500,000 LED street lamps have been installed in 81 cities across the country. Although it still accounts for only 9% of the total number of street lamps in these cities, it is for a new industry. This is indeed a remarkable progress. This cannot be separated from the promotion of "ten cities and ten thousand people."

In September 2011, surveys of 37 pilot cities showed that: Currently, the pilot cities have concentrated nearly 4,500 semiconductor lighting companies, with a total output value of about 140 billion yuan.

With the continuous increase of scientific and technological investment in semiconductor lighting, the research and development of system integration technology has been continuously strengthened and the speed of technological progress has been significantly accelerated. Some of the early problems were integrated through optical design, heat dissipation, and other technologies, and some of the key technologies were solved. Domestic power-type LED chips have been applied to the branch Road Lighting and indoor lighting.

The upstream chip has always been the weakness of China's LED industry and is also the core of R&D. After the promotion of demonstration projects, the localization rate of China's chips has increased from 29% in 2008 to 68% in 2011; the efficiency of high-power chip industrialization has reached 120. Lumen/Watt; silicon substrate power chip with independent intellectual property rights; industrial light efficiency reaches 100 lumens/watt; power type white light semiconductor lighting package is close to the international advanced level; downstream application and international technical level are basically synchronized, indoor and outdoor functional lighting The luminous efficacy of lamps and lanterns has exceeded 80 lumens/watt; these indicators have reached the international advanced level. The integration of domestically produced chips, devices and control systems was applied to the Tiananmen Square screen on the 60th anniversary of the National Day and the big screen performance of the National Theater of the "Revival Road," and achieved good results. After the market operation, the reliability, longevity, lighting design and integrated application of the product have made great progress.

The international financial crisis has affected China’s foreign trade exports. Some traditional industries have experienced a certain degree of decline. However, driven by “Ten Cities and Ten Thousand People”, the domestic semiconductor lighting application market has developed, industrial technology has been improved, costs have decreased, and there is a relative competitive advantage compared with foreign products. According to preliminary statistics, currently 37 pilot cities have implemented more than 2,000 demonstration projects, with over 4.2 million LED lamps and more than 400 million kWh of electricity. Not only that, but according to local planning, there will be more than 7,000 demonstration projects planned for implementation during the 12th Five-Year Plan period.

The Ministry of Housing and Urban-Rural Development issued the outline of the “Twelfth Five-Year” urban green lighting program. The outline stated that during the “Twelfth Five-Year Plan” period, there should be a substantial leap forward in urban green lighting and LED promotion. Industry insiders predict that the "Twelfth Five-Year Plan" is the five-year transition of urban lighting.

The Alliance not only solves the problem of weak innovation capacity. There are more than 5,000 LED companies in China. However, the concentration of enterprises is low, and they are all small-scale private enterprises. There is no LED company with sales of RMB 1 billion at the domestic level. Enterprises only accounted for 16.5% of the market share. On the other hand, R&D strength was insufficient. During the “Eleventh Five-Year Plan” period, China’s LED investment in the entire S&T program was 350 million yuan, which was equivalent to only one year's investment from a Philips company, and we There are more than 100 responsible units.

Faced with the small, scattered and weak industrial status and scattered research and development resources, in order to gain industrial competitiveness and seize the strategic commanding heights of emerging industries, the semiconductor lighting industry must unite to carry out research and development. “In the field of traditional lighting, we are a big producer. In the LED industry, our market has become bigger, our opponents have become stronger, our competition has become internationalized, our past development model is difficult to establish,” and we have established a position in the traditional lighting field. Zhuang Zhigang, president of Xiamen Tungsten Industry Co., Ltd., who is advancing into LED lighting, believes.

Hu Shihui, deputy director of the High-tech Division of the Ministry of Science and Technology, introduced that in 2003, the Ministry of Science and Technology promoted the establishment of a national semiconductor lighting engineering R&D and industrial alliance. Through the strategic alliance of industrial technology innovation, a combination of production, study and research, joint innovation, and platform construction were formed. There are 176 member institutions, including enterprises, universities, and scientific research institutions.

"The establishment of the alliance is not solely to solve the problem of weak corporate innovation capability. The most important thing is to solve the combination of production, education and research, to allow industrialization of scientific and technological achievements, and to allow the industry to grow as quickly as possible." Union Secretary-General Wu Ling introduced, "The alliance Each company does not have to fight for each other, and in terms of research and development, each company's investment is also small, and it solves problems that everyone has, so the results can be shared."

The alliance has played an important role in the development of the LED industry. At present, there are 10 listed companies with LED as the main business. The value of the companies joining the alliance accounts for 90% of the entire industry in the country and 5 recommended technical standards have been formed. In the LED industry, which lacks standards, the league has undoubtedly gained more say.

On November 9, 2011, the International Semiconductor Lighting Alliance (ISA), which was established with China as the lead, held its first member conference in Guangzhou. The alliance members include giants of international lighting companies such as Philips, Osram, and GE. "It can be said that in the strategic emerging industries, this is China's first international organization to initiate and play a leading role, which means that the status of China's LED industry is being recognized by the world." said Yue Ruisheng, Secretary General of the International Semiconductor Lighting Alliance.

At present, the alliance's enterprises are self-financing the construction of "State Key Laboratory of Semiconductor Co-Innovation" and build it into an open and international industrial industrial technology research and development platform. For this platform, companies have shown great enthusiasm. At present, 17 member units have raised more than 15 million yuan.
