As the LED that was born "cold door", it can be said that it is a trek and hardship. Nowadays, with the jump in technology, it has been called the fourth-generation lighting source or green light source. It has the characteristics of energy saving, environmental protection, long life and small size, and can be widely used in various fields such as indication, display, decoration, backlight, general illumination and urban night scene. Therefore, in the current economic situation and the energy crisis, it has become a highly acclaimed new form of lighting.
In recent years, various countries around the world have launched a fierce technical competition around the research and application of LED. The United States has invested $500 million since 2000 to implement the National Semiconductor Lighting Program. The European Union also announced a similar plan in July 2000. With the support of the "863" program, China first proposed the development of semiconductor lighting plans in June 2003.
863 plan lays the foundation of China's LED industry
Before 2002, domestic LED chips were completely dependent on imports. After the launch of the National Semiconductor Lighting Project in 2003, GaN power chips were built from scratch and led to the development of low-power chips, gradually replacing imports. In 2006, the domestic demand for LED chips was 66 billion, and the import volume was 37 billion. The localization rate has reached 44%. It is estimated that in 2007, the number of low-power GaN chips for domestic white light lighting will reach 8 billion, the localization rate will exceed 30%, and the localization rate of power GaN chips will reach 20%.
In 2003, the “Eleventh Five-Year Plan†863 major project of semiconductor lighting has represented the highest level of domestic R&D since its implementation. Nowadays, China's LED epitaxial materials, chip manufacturing, device packaging, phosphors, etc. have all shown unit technology with independent technology property rights. Some core technologies are original, and initially formed from upstream materials, midstream chip preparation, downstream device packaging and A relatively complete R&D and industrial system, such as integrated applications, has laid a foundation for the expansion of China's LED industry to a certain extent.
As of the end of 2008, the National Semiconductor Lighting Project has made significant progress: some original technologies have emerged in exploratory, cutting-edge material growth and device research. 280 nm UV LED device has been developed in China, and the output power of 20 mA reaches the milliwatt level, which is at the international advanced level. The epitaxial growth of non-polar GaN is reduced from the original 780 arc seconds to 780 arc seconds. 559 arc seconds, this value is one of the best results reported internationally; for the first time to achieve large-area nano and thin film photonic lattice LED, 20mA room temperature continuous driving small chip output power from 4.3mW to 8mW; full phosphor type The luminous efficiency of the laminated white OLED has reached 45 lm/W; the 6-piece and 7-piece MOCVD prototypes have been successfully developed and process validation is underway.
China's LED industry has also made major breakthroughs in key technologies for industrialization. The proportion of domestic chip replacement imports has increased year by year, and has been close to 50% so far. The power type white LED package is close to the international advanced level and has become an important LED packaging base in the world. The company's 100 lumens/watt LED manufacturing technology is progressing rapidly. Through the graphic substrate technology and the improved epitaxial layer structure, the power chip package completed on the industrialized line reaches 75 lm/W. The efficiency of the power-type silicon substrate LED chip with independent intellectual property rights is close to 60 lm/W, which is at the international advanced level.
At the same time, the research and major applications of large-scale system integration technology are progressing smoothly. The product range and scale of application products are at the forefront of the world, and it has become the largest producer and exporter of LED full-color display, solar LED, landscape lighting and other application products. Tianjin FAW Xiali and Changzhou Xingyu have developed LED car headlights. In July 2008, Hisense’s first 42-inch ultra-thin LED-backlit LCD TV was launched. It has sold nearly 10,000 units, indicating 40% of world production. Chinese consumer electronics began to use LED technology on a large scale.
The implementation of large-scale system integration technology represented by the Olympic demonstration project has promoted product integration innovation and demonstration applications, showing that it has achieved energy-saving and environmental protection effects and improved the recognition of the international community. In August last year, the opening ceremony of the Beijing Olympic Games and the LED landscape lighting and full-color display used by the venues set a precedent for the large-scale use of LED lighting technology in the history of the Olympic Games. LED has become an important force supporting the Green Olympics and the Olympic Games. According to estimates, only 50,000 square meters of LED landscape lighting in water cubes can save 745,000 kWh and save more than 70% of energy throughout the year. Power LEDs (up to 80?90 lumens/watt with foreign chip packages) have begun to be used in lighting applications such as secondary road lights, parking and gas stations, saving 30% to 50%, and purchasing and operating comprehensive costs for about 3 years. The left and right are level with the traditional light source, and the light efficiency is increased by about 30% every year, and the price is reduced by 40%. About 50,000 LED street lights have been demonstrated in more than 20 cities, and it has become possible to use LEDs for energy-saving renovation of municipal lighting.
Significant achievements have been made in the promotion of standard coordination, and 12 national standards and 7 industry standards are being approved. In particular, members of the organization spontaneously raised funds to deal with the US “337 investigation†patent litigation. The alliance also actively uses the two cities to taste two kinds of resources and promote international cooperation. It has successfully organized the 5th International Forum and Exhibition of Semiconductor Lighting, with a total of 3,000 participants. Participate in the American Solid State Lighting Systems and Technology Alliance (ASSIST), and participate in international conferences as an opportunity to coordinate and promote international standardization.
Through the implementation of major projects in semiconductor lighting engineering, it is expected that in 2010, China is expected to break through the core technologies of materials and devices, so that the luminous efficiency of white light reaches 130lm/W, the industrialization level reaches 100lm/W, and more than 200 invention patents are applied to further reduce costs. In the main links of the industrial chain, 2 to 3 leading brand enterprises have been formed, and the application has begun to enter the field of general lighting. The scale of related industries has reached 100 billion yuan, and the annual energy saving has reached 50 billion degrees, eventually forming independent intellectual property rights and international competitiveness. China's semiconductor lighting emerging industry.
Ten Cities and Wanlings Blowing China LED Industry Assembly Number
It is understood that in 2008 China's semiconductor lighting industry output value of nearly 70 billion, the chip localization rate of nearly 50%. At present, there are more than 3,000 semiconductor lighting related enterprises in China, and there have been downward extensions of upstream and midstream enterprises. The signs of mergers and acquisitions have emerged. In the first quarter of this year, orders for packaging and application companies rebounded rapidly. In the context of the financial crisis, China's semiconductor lighting industry presented The trend of rising against the trend. In 2009, the “Ten Cities and Ten Thousand Miles†application demonstration project will bring a historical opportunity for rapid development of the semiconductor lighting industry.
On May 21, 2009, the Ministry of Science and Technology organized a seminar on the Pilot Work Program for the Pilot City of “Ten Cities and Ten Thousands†Semiconductor Lighting Application Engineering. In 2009, on June 19th, the “Ten City Wanhao†semiconductor lighting application project of the Ministry of Science and Technology was launched in Dalian. 21 cities including Dalian, Shenzhen, Shanghai, Tianjin and Hangzhou have become pilot cities for “Ten Cities and Ten Thousands†semiconductor lighting application projects. On August 31, the launching ceremony of the pilot project of the “Ten Cities and Ten Thousands†semiconductor lighting application project was held in Weifang, Shandong Province, and the national campaign of the “Ten Cities and Ten Thousand Miles†project was announced.
The goal of “Ten Cities and Wanhao†semiconductor lighting application project is to apply 6 million semiconductor lighting products to municipal projects in the pilot cities in 2011, directly driving domestic demand by 15 billion yuan; by 2015, semiconductor lighting will enter 30% of general lighting market. Constant semiconductor lighting (LED) is considered to be the most promising high-tech green industry in the 21st century due to its environmental protection, energy saving and long life. The development of LED lighting has become the focus of the global lighting industry.
2009 is known as the first year of white LED entering universal lighting, and the financial crisis has highlighted its importance. The implementation of the “Ten Cities and Ten Thousand Miles†project marks the main battle of the semiconductor lighting industry to gradually enter the industrial economy. Today, the implementation of semiconductor lighting projects led by 21 cities is booming. In this interview, we have taken a look at the implementation status of the “Ten Cities and Ten Thousand Cities†project in several typical cities for your reference.
In 2005, this magazine has carried out detailed follow-up reports on the LED industry, and has published a series of reports to prospectively reveal the development of the upcoming LED industry.
Ten years of grinding a sword, four years is not short. Today, LED is entering the people's attention with great fanfare. Enter "LED" and the results from the search engine may be 80-90% about LED backlight TV. Although LED lighting seems to be hiding in the "deep", but it can not hide the fact that it is hot.
Dongguan: “Thousands of Miles†and “Ten Cities and Ten Thousands†are in parallel with the new problems facing the LED lighting application pilot project. Recently, the “Photovoltaic Industry Development†forum was held in Dongguan Science and Technology Museum, and invited to the Ministry of Industry and Information Technology Electronics Research Institute. Experts and professors from Tsinghua University will focus on the future development of the LED industry and how to enhance the competitiveness of the LED industry cluster in the international market.
According to the reporter, He Jianzhong, a high-tech industry branch of the Dongguan Science and Technology Bureau, learned that the LED demonstration project is one of the tasks in the major special guidelines of Guangdong Province. In specific operations, it is encouraged to first go up the road or carry out relevant road sections. Rectification project. The target for 2008 is 5,000 LED lights, but only 3,000 布 has been completed due to reality, and the remaining tasks continue to roll as the next round of plans. The target for 2009 is 9000 baht, implemented in 6-7 towns. As a special project of energy saving and emission reduction in Guangdong Province, the LED street lamp demonstration project of “Gianli 100,000†project.
At the beginning of this year, the Guangdong Province High-power LED Street Light Demonstration Promotion Conference was held in Dongguan City, and the “Tianli 100,000†high-power LED street lamp industrialization demonstration and promotion project was launched. This project refers to the construction and demonstration of LED street lights with a total mileage of 1,500 km and a scale of about 100,000 in Guangzhou, Dongguan, Foshan, Zhongshan, Zhaoqing and Shantou. It is announced to the world that LED lighting has moved from traditional landscape lighting to road lighting and has been successfully scaled up.
Promoting the popularization of LED street lamps and developing and expanding the LED industry are of great significance to the adjustment of industrial structure and energy conservation and emission reduction in Guangdong Province. In order to enlarge and strengthen the LED industry in Guangdong Province, Guangdong first formulated the LED industry technology roadmap to clarify the technology needs, priority themes, time nodes and development paths of the LED industry in the next five years and beyond. Secondly, the organization and implementation of the "green lighting project": First, continue to implement the "energy-saving emission reduction and renewable energy" major science and technology projects, focusing on high-power chip manufacturing, lighting structure optimization design and chip cooling and other key technologies. The second is to plan and implement the “Tianli 100,000†high-power LED street lamp industrialization demonstration and promotion project. The third is to build an LED industrialization base, focus on optimizing the regional layout of the LED industry, improve the industrial supporting capacity, and guide the transformation and upgrading of the traditional lighting industry. Then further optimize the policy environment, improve the financial service system, and promote the organic integration of technology capital, industrial capital and financial capital. Fully promote the "enterprise + user + bank" model, and introduce more strategic investment partners for the large-scale application of LED street lighting products.
Fuzhou: External guidance inline progress steadily
As a pilot city in the country's “Ten Cities and Ten Thousand Cities†pilot city, it can be said that it is concentrated in the strength of its forces.
On the afternoon of September 8, the information industry counterpart meeting of the 13th China International Investment and Trade Fair hosted by the Fujian Provincial Information Technology Bureau was held at the National Accounting Institute. For the “Investing in Haixi†information industry counterparty held by the Provincial Information Technology Bureau this year, the Taiwan Lighting and Lighting Export Industry Association is a new guest. Its presence is iconic. Because this association is responsible for the downstream of the information industry, it shows that the information industry cooperation between Fujian and Taiwan is extending to the upstream and downstream of the industrial chain.
Taiwan's lighting industry has been popular all over the world. With the deepening of cross-strait economic and trade exchanges and cooperation, many Taiwanese lighting industries have moved to the mainland and gained new development. In recent years, the LED industry has grown stronger. Many traditional lighting companies are looking for a combination with LEDs, but they have no technology. At the same time, emerging LED companies also hope to find new growth points in lighting, but lighting is an art. It is to serve people's lives. Although LED companies have technological advantages, they lack experience in the lighting industry. Taiwan's lighting and lighting output industry association is the "matchmaker" of the traditional lighting industry and modern LED technology cooperation.
Nowadays, Fujian's LED industry development has a very solid foundation. Many places have built parks with optoelectronic main industries, and have formed a complete industry from raw materials, production, processing to sales. According to the relevant person in charge of the Fuzhou Science and Technology Bureau, the LED in Fuzhou is currently in the exploratory stage, but because of the lack of relevant policy guidance on technology and standards, it can only be explored. For example, the installation experiment is carried out on certain sections of the road for half a year, and the relevant parameters are determined to provide judgment for scientific analysis. As a specific plan related to the ten cities and cities, no basis has been introduced.
Shijiazhuang: The plan is introduced with a total investment of 300 million yuan
The pilot project of the “Ten City Wanhao†semiconductor lighting application project in Shijiazhuang City, Hebei Province has been established, and the program will promote the health and rapid development of the semiconductor lighting industry in Shijiazhuang.
Shijiazhuang City's "Ten Cities and Ten Thousand Miles" LED application project promotion mode adopts the government's driving, demonstration promotion and market-driven approach. The total investment of the project is 300 million yuan. The city's LED street lights and tunnel lights are gradually promoted and used in the city. 20,000 ç›, LED screw light, LED tube 130,000 ç›, LED ceiling lamp 0.8 million ç›. The project is invested in 20 million yuan for gas station lighting, 140 million yuan for LED street lamps and tunnel lights, 70 million yuan for LED indoor lighting projects, 20 million yuan for LED lighting integrated application projects in Shijiazhuang International Airport, and 50 million yuan for garden LED lighting. It is estimated that the accumulated power saving will be more than 20 million degrees in 2011. In 2011, the scale of LED municipal lighting industry in Shijiazhuang reached 3 billion yuan, driving the output value of semiconductor lighting related industries to more than 10 billion yuan. The project can save more than 12 million kWh of electricity.
Shijiazhuang City will adopt a series of policy measures to promote project implementation and industrial development. First, encourage enterprises to undertake key projects of the “Semiconductor Lighting Project†of the Ministry of Science and Technology and the Science and Technology Department of Hebei Province. Support enterprises with independent intellectual property rights and core competitiveness to develop new products, strengthen research on product reliability and test and inspection, improve product competitiveness, and cultivate and support leading enterprises with influence and radiation capabilities in the national LED industry.

The third is to encourage enterprises and institutions to use LED lighting products, and the Shijiazhuang Municipal Government grants 10% subsidies to approved lamps. Fourth, LED lighting products are preferred in urban roads, streets, communities, gardens, and government office buildings. The fifth is to ensure the quality of LED lighting products. Make full use of the National Semiconductor Device Quality Supervision and Inspection Center (Hebei Semiconductor Lighting Inspection Center) to inspect and evaluate the products provided by the company, and provide quality assurance for the semiconductor lighting application engineering in Shijiazhuang.
Chengdu: 3 years 15000 ç› play a clustering effect
In May of this year, Chengdu became the first batch of “Ten Cities and Ten Thousand Cities†pilot cities in the country.
According to Wang Fangquan of the High-tech Department of Chengdu Science and Technology Bureau, on June 24, Chengdu officially issued the “Chengdu “Ten Cities and Ten Thousand Cities†Semiconductor Lighting Application Engineering Pilot Implementation Plan (2009? 2011)â€, which is the next three years. The city's LED lighting technology innovation and industrialization and the application of regulatory documents. At the same time, the city's LED industry development plan, application engineering awards and other documents will also be introduced. These normative documents cover demonstration projects, model policies, industrial development goals and key directions, organizational safeguards, etc., and will create a good policy environment for the development of LED industry and market applications. It is planned to carry out demonstration projects in stages and in stages within 3 years to promote LED street lights, tunnel lights and landscape lighting over 15,000 miles. Drive the market through application, guide enterprise technology innovation, accelerate industrial development, and raise public awareness and acceptance.
According to reports, in recent years, Chengdu has accelerated the cultivation of the LED industry and created a favorable environment for promoting industrial development. The scale, technology level and application promotion of the LED industry have achieved positive results and become one of the major gathering areas of the domestic LED industry. On the basis of the support policy, the first is to further plan the development goals and key directions of the LED industry on the basis of the existing photovoltaic photovoltaic industry cluster development plan. The second is to actively expand the field of LED applications, adopt measures to promote municipal public lighting applications, supporting the development of backlight projects, and encouraging commercial organizations to use LEDs. The third is to introduce the “Ten Cities and Ten Thousand Miles†demonstration policy, including incentives for government procurement and application engineering awards. The fourth is to strengthen the maintenance of market order, and have carried out actions such as technical standards demand research and product quality inspection, and standardized LED products.
At present, the pilot work of the “Ten Cities and Ten Thousand Miles†pilot project in Chengdu has been carried out in an orderly manner. The first batch of LED lighting demonstration projects such as Gaoxin West New Road and Xinjin Hope Avenue have entered the implementation stage.
According to the characteristics of LED products and the application requirements of relevant places, Chengdu selected roads, subways and landscape buildings to carry out demonstration projects in batches, which reflected the outstanding key areas, the gradual deepening of the pilots, the application to drive the market, and the post-disaster reconstruction. In the development of the LED industry, we will actively explore the development path of the industry to encourage the market to cultivate the industry, make full use of the potential LED lighting market resources, guide technological innovation, and support and introduce a group of LED enterprises with independent property rights and core competitiveness. Promote good and fast development of the industry.
At present, there are many domestic LED manufacturers, and the products are mixed. Wang Fangquan said that there is no national standard for LED street lamps, which brings certain difficulties to the promotion and application of LED street lamps. In addition, it is necessary to further reduce LED costs and improve product quality through technological upgrading and scale production.
Wuhan: Planning guidelines boost industry independent innovation
According to the "Tianjin Ten Cities Wanhao Semiconductor Lighting Application Engineering Pilot Work Plan" (hereinafter referred to as the "Program") issued by the Wuhan Municipal Government on July 1, the solar energy and semiconductor lighting LEDs will be combined according to the mature technology. Promote the application of long-lasting energy-saving and environmentally friendly LED functional lighting application products in key areas (areas) suitable for the development of LED lighting in streets, stations, development zones, residential quarters, tourist attractions and indoor lighting. We will strive to install 36,000 LEDs in the newly launched and new demonstration projects in three years, including 26,000 室外 outdoor lamps and 10,000 室内 indoor lamps, to fully promote the construction of Wuhan Semiconductor Lighting Application Demonstration City.
At the same time, "Plan" clearly states in the conditions of LED lighting product supply enterprises: the registered capital in this city is not less than 20 million yuan, or the registered capital is more than 10 million yuan and the annual product sales are more than 50 million yuan, with legal personality.
