“This is the first time in more than a decade in Shenzhen that the LED project has been included in the list of major industrial technology issues. It is also the first time Shenzhen has promoted the development of the LED industry in this way.†This is the high-tech industrialization of Shenzhen Kexin Bureau. A statement by Director Wen Wenhui at the Interpretation Conference on LED Industry Support Policy. Just a week ago, the Shenzhen Municipal Government issued three documents in a bulletin on promoting the development of LED and semiconductor lighting industry in Shenzhen. ??
"We are very excited and very happy. The city leaders have finally attached great importance to our industry." The heads of several semiconductor lighting and LED companies all expressed the same voice. "Now I feel very energetic." ???
â—Ž Shenzhen should take the lead in leading and demonstrating role??
"Now, Shenzhen is very excited to support the development of the LED industry. From the personal feelings and from the objective situation, Shenzhen's semiconductor lighting industry should play an exemplary role in the country." This is National Semiconductor. Wu Ling, Secretary General of the Lighting Engineering R&D and Industry Alliance, commented on the LED industry in Shenzhen. “I often talk to other provinces that engage in LED institutions and enterprises. You are not a big deal. You have to go to Shenzhen to see.â€
The reporter also learned from the relevant information obtained by Shenzhen Science and Technology Bureau that the Shenzhen LED industry began in the early 1990s. After more than ten years of development, Shenzhen LED industry has developed rapidly. More than 700 companies engaged in the research, development, production and application of semiconductor lighting technology and products account for nearly half of the country. In 2007, the industry scale was about 15 billion yuan, and the number of employees exceeded 120,000. At present, Shenzhen has become the world's largest production and supply base for solar LED lamps, the world's major production and supply base for LED backlights, the largest domestic production and supply base for LED displays, and the main domestic production areas for LED packaging and special industrial lighting. ???
Shenzhen LED industry is basically formed by relying on the development of electronic information industry. It has formed a certain industrial cluster in each district, showing the characteristics of relatively concentrated in Baoan District and Nanshan District. From the perspective of enterprise agglomeration, Shenzhen LED enterprises have formed a relatively complete domestic industrial chain in the upstream substrate materials, epitaxial wafers, midstream chips, downstream packaging, applications and supporting materials, processing and testing equipment. A certain industrial agglomeration has formed in the middle and lower reaches of the industrial chain. According to incomplete statistics, among the LED enterprises in Shenzhen, the application products enterprises, packaging enterprises and supporting enterprises each accounted for about 33%, and the upstream and downstream enterprises such as epitaxial chips accounted for about 1%. ???
“In the domestic market, for example, Shenzhen occupies one-third of the entire market. From outdoor display to lighting applications, it is ranked first in the country for mid-range packaging and applications.†Jin Peng introduced, “ At the same time, Shenzhen has considerable strength in front-end chip design. At present, Shenzhen is building the world's largest front-end chip production base."
According to the data, Shenzhen LED enterprises have taken the lead in breakthroughs in applications such as backlights, displays, solar LED applications, and special work lighting, enabling LED companies in these areas to develop rapidly. Driven by the city government's encouragement of science and technology innovation policy, the technological innovation capability of Shenzhen LED industry has gradually increased. A number of independent innovation enterprises have emerged. As of June 2008, Shenzhen LED enterprises have applied for 1,121 patents, ranking the whole country. first. From the perspective of product structure, the products of Shenzhen LED industry are widely distributed, covering almost the current product categories of the LED industry.
In 2007, extensions and chips accounted for less than 1% of total sales, packaging accounted for about 30% of total sales, applications accounted for about 60% of total sales, and supporting approximately 9% of total sales.
"But most of the core patents of LED are in the hands of foreign companies, so our LED products are often subject to one or the other technical and patent barriers." Jinpeng said with some regrets, "for example, using phosphors, Phosphors plus blue light, such patents have applications. Foreign companies have a wide range of patent coverage."??
?? â—Ž LED promotion still needs to reduce costs???
As the president of the electronic information industry in Shenzhen and the president of the Shenzhen LED Industry Association, Wang Dianzhen said that although China is a big country in production, it is not a big country, especially in daily lighting. Traditional lighting tools are also used. ???
"In China, LEDs are used more in outdoor displays and car electronics, such as large displays, such as car taillights. At present, 50% of new cars use LEDs in taillight technology. Expanded to 80%. LED lighting is currently widely used in foreign countries, especially in Europe and the United States, and is not fully promoted in China.†Jin Peng believes that LED is not effectively popularized in daily general lighting, it is compared with its current Production costs and sales prices are closely related, and the price of LEDs is much higher than the price of traditional lighting tools. ???
“In an example of a 10 square meter room lighting requirement, the amount of light required is 600 lumens per watt. If an incandescent bulb is used, a 40 watt bulb is required, and with LEDs, only one watt is required, but the price of one watt of LED is 20 Block money, then 5 watts will get 100, how much do you need an ordinary incandescent bulb?" Jin Peng said. ???
At the same time, Jin Peng said that the high cost of materials in production costs is the main factor leading to high LED prices. ???
"Now an LED lamp, the cost of the chip accounts for more than 50%," Jin Peng said, "many LED chips are made of sapphire as a substrate, and even some use more expensive silicon carbide."
Although LEDs are not effectively popularized in the daily lighting of residents due to price factors, Jinpeng believes that LEDs are still advantageous in urban public transportation and road lighting. ???
"First of all, LED energy saving, ordinary street lighting power consumption is so large, LED can save a lot of energy; secondly, the durability of LED is very good, after installing one up, it will not be changed for a long time, so you can also save Maintenance costs.†Jin Peng believes that “at the same time, LEDs need less power, and the wires of the power supply lines are not as thick.â€
Wu Ling recently said at the Shenzhen LED Policy Interpretation Conference that the South Korean government has proposed that the Korean semiconductor industry should become the world's top three by 2018, so at this time China's semiconductor lighting can not have a place in the world, now it is very important. time. ??
Wu Ling also said that one of the bottlenecks hindering the development of LED is the testing standard, the energy efficiency testing standard. LED is a very immature industry in the world, and there is no standard in the world, let alone the detection method.
"Semiconductor lighting technology is still in the stage of maturity. There is no uniform testing standard in the world so far, so its market competition is relatively disorderly." Wu Ling said, "We should first encourage corporate standards and industry standards. And then gradually rise to the national standard, or the national standard is not introduced, we can only wait."?
"We are very excited and very happy. The city leaders have finally attached great importance to our industry." The heads of several semiconductor lighting and LED companies all expressed the same voice. "Now I feel very energetic." ???
