          Green lighting lights up the future to build LED industry chain

          Light-emitting diodes have never been as much of a concern as they are now.

          This new type of illuminating technology called "LED" was born in the 1960s. Until the 1980s and 1990s, its application was limited to signals, signs, digital displays, etc., but the price was only a few cents.

          Since the end of the last century, with the maturity of technology, LED lighting has shown great advantages in energy saving and environmental protection, improving lighting quality and efficiency, and its application has become more and more extensive.

          Today, LEDs are like people's lives. Household LED energy-saving lamps and LCD TVs for LCD TVs are changing people's living habits. Large buildings such as the Water Cube and the Oriental Pearl Tower are also more beautiful due to LEDs. The Shanghai World Expo has used a record 10.3 billion LED chips, indicating the dawn of LED efficient lighting.

          The energy conservation and environmental protection industry has been listed as a strategic emerging industry. As a sub-industry, can LED lighting seize the once-in-a-lifetime development opportunities and develop steadily and healthily? Recently, we have come to an emerging LED industry base - Guangdong Province Nanhai District, Foshan City conducted an interview survey.

          The new light source base is ready to go

          Luocun, Nanhai District, Foshan City, Guangdong Province, was one of the largest electric light source production bases in the country, with more than 400 lighting companies. Today, these companies are seeking to transform themselves into the semiconductor lighting industry. According to the "market + base" model, a new light source industry base is ready to go

          Foshan is an important electric light source production and R&D base in China, and Nanhai District is the core area of a€?a€?Foshan electric light source lighting industry chain.

          When I came to Luocun Street in Nanhai District, the reporter saw that a large area of a€?a€?land had been sorted out and developed. a€?In order to develop the new light source industry, we have carried out the a€?three old renovationsa€? of the old towns, old factories and old villages, and compiled the land for the construction of the new light source industrialization demonstration base in Guangdong.a€? Any of the leaders of the economic development office of Luocun Sub-district Office said that .

          According to Chen Jianbin, deputy director of the Nanhai District Science and Technology Information Bureau, the first phase of the Guangdong New Light Source Industrialization Demonstration Base covers an area of a€?a€?1,500 mu. It is a major science and technology project in Guangdong Province, and it is also an accelerated urban-style industry construction in the South China Sea. It fosters strategic emerging industries and promotes energy conservation and environmental protection. An important carrier of green lighting engineering.

          Why is South China's determination to develop a new light source industry so great? He Yucong explained that a€?Luo Cun was originally one of the largest electric light source production bases in the country, with more than 400 lighting companies under its jurisdiction, with a total output value of nearly 6 billion yuan last year. The rapid development of the semiconductor lighting industry has become a new trend in the development of electric light sources. The lighting enterprises in Luocun have begun to transform and develop. The new light source has become an inevitable choice."

          a€?Market + Basea€? is a unique model for the development of new light source industry in the South China Sea

          On the Luhu North Lake Road, which is only one street away from the Guangdong New Light Source Industrialization Base, the reporter saw a large group of buildings with a colorful banner hanging on it, with the words a€?LED World, Lighting Kingdoma€?. a€?This is the South China (International) electric light source lighting city that will open in August this year.a€? Yang Houhua, general manager of South China (International) Electric Light Source Lighting City, said, a€?South China (International) Electric Light Source Lighting City is known as 'Thousands of Mu Professionals The market's total investment of 1 billion yuan, involving lamps, lighting, accessories and other related products. At present, Foshan Lighting, Philips, Osram and many other well-known brands at home and abroad have been stationed."

          a€?At present, the renting of two thousand shops in the first phase of the Lighting City project is close to 90%, of which one-third of the stores are associated with LEDs. At the same time, we have also set up LED showrooms to build a communication platform for LED manufacturers. In the near future, LED must be the mainstream product in the market." Yang Houhua said.

          In June this year, Nanhai District signed a strategic cooperation agreement with the National Semiconductor Lighting Engineering R&D and Industry Alliance to jointly establish the Foshan Semiconductor Lighting Technology Promotion Center and set up the first sub-center of the alliance in the new light source industry base in Guangdong Province. .

          In order to speed up the development of the industry, Nanhai District has introduced measures to accelerate the development of the semiconductor lighting industry in October 2009, and established a special fund for industrial development with a total scale of 1 billion to 2 billion yuan to enhance the capacity for independent innovation and strengthen the construction and construction of public platforms. Demonstration projects, promotion of investment and financing, etc. give strong support to industrial development, and strive to form a scale of 30 billion to 50 billion yuan in the next three to five years, becoming a well-known semiconductor lighting industry base in China.

          Create a full industrial chain model

          In the development of the LED industry, the South China Sea focuses on the development of the entire industrial chain model, from the upstream materials, electric light source to downstream lighting, molds and applications, all links are closely combined. At present, Nanhai has the strong integration and support capabilities of the upstream and downstream of the industrial chain.

          I came to the Foshan Research Institute of Zhongshan University in Nanhai Software Park, Foshan City, Guangdong Province. The reporter found that the companies that are adjacent to the institute are engaged in LED production.

          Wang Mengyuan, executive vice president of Foshan Research Institute of Sun Yat-sen University, explained, a€?The Foshan Research Institute of Sun Yat-sen University focuses on the research and development of key technologies for semiconductor lighting systems. The technologies we develop are closely related to the company, and can be industrialized and reduced. The advanced technology of synergy, so the relationship between the company and us is inseparable."

          Said, Wang Mengyuan showed reporters a new technology that they have completed research and development and is cooperating with enterprises to realize industrialization--multi-chip integrated packaging technology. "The spot light source of one strain cannot be seen on this chip. We use The multi-chip integrated packaging technology turns it into a surface light source, which has higher light efficiency and higher color rendering than the point source, and the cost is reduced by about 10% compared with the point light source of the common one-watt chip, and the technology is easy to realize the industry. Production." Wang Mengyuan handed a 6-watt LED new product to reporters to explain the advantages of new technology. a€?At present, this technology is leading the world and we are applying for a patent.a€?

          The introduction of research and development institutions such as the Foshan Research Institute of Sun Yat-sen University is an important part of Nanhai District's model of building an LED industry chain. "At present, it seems that the development model of building a whole industry chain of semiconductor lighting is very suitable for Nanhai District." Chen Jianbin said.

          He said that the emerging industry of Nanhai Semiconductor Lighting is not developed out of thin air, but is developed on the basis of the original traditional industry and closely related to the original traditional industry in the South China Sea. In the 1990s, the electric light source industry was the traditional pillar industry of the South China Sea, forming a large number of industrial clusters matched with electric light sources, which also laid a solid foundation for the production of LED industry. At the same time, there are many small hardware production bases in the drains of the South China Sea. With the changes in lighting and lighting, the hardware is constantly changing the product types to adapt to the development of semiconductor lighting.

          It is with such a foundation that Nanhai pays attention to the development of the entire industry chain model when developing the LED industry.

          "Complete industry chain can reduce costs, reduce the cost of supporting products, and ensure sufficient supply. For example, chips and substrates are often out of stock. We will have such problems without our own manufacturers." Chen Jianbin said. At the same time, the original supporting enterprises can find suitable entry points for production, drive the coordinated development of all links in the industrial chain, and finally achieve sustainable development.

          Chen Jianbin gave an example. In the South China Sea, a company that produces electronic and electrical appliances has made the humidifier products a blue-and-white porcelain bottle and added LED lighting technology. The humidifier not only has a scene lighting function, but can also be used as a desk lamp. a€?These products are very popular in China, and they are also exported to foreign countries, which will bring huge profits to the company.a€?

          By building the entire industrial chain, Foshan has become an important production and research base for electric light sources in China. As the core area of a€?a€?Foshan's electric light source lighting industry chain, Nanhai has strong integration and support capabilities in the upstream and downstream of the industrial chain, from upstream materials and electric light sources. Downstream lighting, molds and applications are very complete, and each link is closely combined. It has a group of national and even world leading enterprises such as Foshan Lighting, Osram, and Snow Wright, and is supported by Luocun Electric Light Source Lighting in Nanhai District. The scale of the lighting electrical industry cluster. The industrial cluster and the adjacent Danzao hardware, Dali industrial aluminum, Lishui mold, Shishan's optoelectronics, Guicheng's mechanical equipment manufacturing and the entire Foshan area's largest small household appliance industry cluster together to build Foshan electric light source lighting The complete chain of industry.

          Break through technical bottlenecks

          At present, the application of LED in landscape lighting, screen display and other fields has entered a relatively mature stage, and the application of high-power LED lighting has just started. Mastering the raw materials and epitaxial growth equipment of epitaxial wafers, breaking through the key technologies of LED epitaxy and chip manufacturing, and attaching importance to the cultivation of high-end talents has become the key to industrial development.

          Hu Zhaoguang, deputy director of the State Grid Energy Research Institute, pointed out that semiconductor lighting has three major advantages: First, energy saving, under the same lighting brightness conditions, LED lights save more than 40% to 50% of the average lamp, and the maintenance and repair costs later. Very low, almost no maintenance cost within 3 to 5 years after installation and use; second, environmental protection, the lamp does not contain harmful substances such as mercury and lead, and harmful gases; third, long service life, the average service life of LED lamps can reach 5 Up to 100,000 hours, 3 to 5 times that of ordinary lamps.

          It is precisely because of these characteristics that semiconductor lighting is recognized as the most promising high-efficiency lighting industry in various countries. It is called another revolution after the illumination source of incandescent lamps and fluorescent lamps. It represents the future development direction of the world lighting industry, not only the current response. The international financial crisis and the important breakthrough to maintain stable and rapid economic development are also important ways to promote new technological revolutions, foster new industries, promote energy conservation and emission reduction, and respond to global climate change.

          However, China's LED has entered a relatively mature stage in landscape lighting, screen display and other applications, but its application in high-power LED lighting has just started.

          Wang Mengyuan analyzed that the reason why LED high-power lighting is difficult to popularize is mainly high cost and high price. At present, LED white light can reach an illumination of more than 100 lumens per watt, which can meet the functional requirements such as indoor reading, but the price is 3 to 8 times higher than that of conventional lamps.

          "The main reason for the high cost is that the raw materials, epitaxial growth equipment and core technology for the production of epitaxial wafers are in the hands of foreign companies." Wang Mengyuan analyzed that at present, most of the LED manufacturers in China are in the packaging and application fields downstream of the industry. Domestic enterprises can compete with foreign companies on the upstream core of R&D, and the cost will decrease.

          According to statistics, in 2009, the output value of the national LED industry reached 82.7 billion yuan, of which the application value in the lower end of the industry was more than 60 billion yuan, and the key components of substrate materials, epitaxial growth and chip manufacturing involving core technologies, domestic enterprises. Only created an output value of about 2.8 billion yuan.

          "In addition to LED epitaxy and key technologies for chip manufacturing and key equipment relying on imports, the lack of talent will also become a weakness that constrains the development of the industry." Wang Mengyuan said.

          At present, China's semiconductor lighting industry talents are extremely scarce, and high salaries are not hired. Without cutting-edge talent, it is impossible to break through the core technology, and even the introduction of the core production equipment will not operate.

          Fortunately, in May of this year, Guangdong Zhaoxin Enterprise Group Co., Ltd. independently developed and manufactured the first domestic semiconductor lighting chip core equipment, which means that the long-term domestic dependence on imported LED chip manufacturing equipment will be broken.

          When he came to Guangdong Zhaoxin Enterprise Group Co., Ltd., Chairman Liang Fengyi told reporters that the equipment is still in the trial operation stage. After successful production in the future, it will break the monopoly of such equipment, which has been monopolized by US, German and Japanese companies. Domestic enterprises will at least reduce production costs by 30%. In the future, there will be more middle and upper reaches companies that produce epitaxial wafers and chips.
