“In 2009, industry development exceeded expectations. In March last year, corporate investment and capacity expansion accelerated.†At the 5th China LED Industry Summit Forum, Tang Guoqing, general manager of CREE China, said. Xu Liancheng of Guangdong Zhaoxin Group expressed the same view. "The LED industry is expanding at an unprecedented speed. In 2010, it was defined as the first year of LED industry development." The hot scene of the forum also supported their views.
The forum was jointly organized by Gaogong LED and Tianjin Dongli District Government. Nearly 300 industry leaders from all over the country attended the forum. Speakers include Zhang Youhui, Secretary of Tianjin Dongli District, Chen Yansheng, Chairman of China Lighting Association, and Guan Baiyu, Deputy Inspector of Electronic Information Department of Ministry of Industry and Information Technology, and other senior officials of the government. And CREE China Market General Manager Tang Guoqing, Philips Global Technology Development Center Zong Mingcheng, Osram Senior Sales Manager Yang Wei, GE Systems Engineering Manager Sun Hui and other international giants.
During the meeting, senior executives of the company were also invited to visit Huaming New Town, Huaming Industrial Park and Dongli District Planning Exhibition Hall. At the welcome dinner on the 19th, the signing ceremony for the establishment of the Tianjin Dongli National Semiconductor Lighting Engineering High-tech Industrialization Base was held. Nine companies signed a letter of intent for investment cooperation, and 56 companies signed the “Developing Low-Carbon Economyâ€. Jointly promote the “Proposal for the Construction of Tianjin Binhai National Semiconductor Lighting High-tech Industrial Baseâ€.
Dr. Zhang Xiaofei, director of the High-tech LED Industry Research Center, said that Tianjin is an important LED industry base in northern China. Sanan recently invested billions of yuan in Tianjin. Tianjin Economic and Technological Development Zone is China's first LED city demonstration zone. Tianjin University of Technology opened. In order to strengthen the communication and cooperation between China and especially the LED enterprises in the northern region, we specially set the venue of the 5th China LED Industry Theme Summit Forum in Tianjin.
Zhang Youhui, secretary of the Dongli District of Tianjin, told reporters that Tianjin is vigorously developing new materials and new energy industries. LED is their key development direction. The district is preparing to set up venture capital to develop high-tech industries. Zhang Shuji believes that it should start from cultivating and introducing leading talents. The purpose of this forum is to promote the investment promotion activities of LED projects.
The forum's topics cover the hot topics of the current LED industry, such as market opportunities, technology trends, and ten cities. The experts at the meeting expressed their opinions and made a thorough and in-depth discussion on all aspects of the LED industry.
LED is changing China
What changes will LED bring to China? Tang Guoqing believes that LED will change China from three aspects: the government changes China through government projects and guidance documents such as the Olympic Games and the World Expo; market demand drives LED penetration into China's home lighting, backlight and landscape; in the process of LED popularization, A low-carbon society and environmental awareness will penetrate the hearts of Chinese people.
Tang Guoqing pointed out that in 2009, there were more than 40 companies engaged in the production of LED chips in China. The company has more than 150 MOCVDs, of which more than 135 production GaN MOCVDs have been installed, and about 18 production MOCVDs. The research equipment of the institute has also increased, and the epitaxial chip investment plans of various enterprises have been further accelerated, and its development has greatly exceeded the forecast in early 2009.
Dr. Najing Liang Bingwen of Suzhou pointed out the direction of China's LED industry, accelerated the establishment, testing and supervision of standards; established a professional talent training and training system; established a professional job evaluation system and procedures; established a patent pool and market demand information platform.
Where are the current market opportunities?
The hot scene of LED industry investment in 2009 is unforgettable. The stocks of related listed companies have also been put on the ceiling. In the case that the industry may be overheated, many investment opportunities are questioned. Yang Wei said that high-efficiency, low-cost and long-life white, red, green and blue, infrared high-power LEDs and laser diodes will be the focus of Osram's future research and development. Various technical standards will raise the industry threshold, and some enterprises will be forced to withdraw because they are not up to standard. "Osram Opto Semiconductors is ready to fill the light source gap caused by the standard technology ban."
Tang Guoqing stressed that CREE will continue to focus on two major areas of lighting and display | display devices, supplying millions of LED devices of more than 100 lm / W per week. In response to future market demand, CREE will continue to expand its production capacity.
Xie Guanbin, a Beijing-based law firm, believes that in the face of attractive market opportunities, companies should pay attention to LED patent issues. The current status of domestic LED patents is: the industry is far from mature, and there are a wide range of technical fields yet to be developed. Some basic patent protection periods are about to expire, and licensing, cross-licensing, and authorized commissioning production are increasing. Xie Guanbin believes that enterprises should learn to legally use advanced technology, track patents that are about to expire, sign patent licensing contracts, anti-monopoly licenses, cross-licensing, and authorized production, and open up markets to countries where patents are not covered.
As a venture capitalist, Tongchuang Weiye partner Ding Baoyu said his investment strategy. He believes that the high uncertainty of the upstream industry is more suitable for venture capital, while the middle and lower reaches are more suitable for PE investment or industrial capital. Ding Baoyu predicts that in the next three to five years, whether it is upstream or downstream of LED, there will be a number of enterprises listed, and the total number of newly listed enterprises will reach 5 to 10. Tongchuang Weiye successfully invested in Dalian Luming and Maoshuo Power Supply | voltage regulator.
Gaogong LED Dr. Zhang Xiaofei believes that LED backlight will be the biggest contributor to the expansion of LED market this year. Although the LED lighting field is expanding rapidly, the overall market is still small. However, looking forward to the next three to five years, lighting and backlighting will become the main driving force for the development of the LED market.
Opportunities and challenges brought by EMC
With the deepening of the ten-city project, a brand new term “contract energy management (EMC)†is gradually becoming familiar. Sun Jianhua of Destada Optoelectronics believes that it is necessary to take the government as the leading factor and gradually explore the EMC model in line with China's national conditions. Private capital has the opportunity to make a profit from EMC. EMC has broken through the bottleneck of investment in LED streetlight demonstration projects with high investment and high risks, ensuring maximum benefits and minimization of risks in production, consumption and finance.
However, Sun Jianhua also believes that there are certain risks in the promotion of EMC in China. The LED street lamp standards and application standards are not perfect or missing. At present, some problems have appeared in the application, and it should not be ignored as soon as possible; EMC is not a perfect one. The model needs to be further explored for improvement; product quality and reliability will directly determine success or failure.
How do investors choose LED companies?
The LED industry is booming, and related companies have become the target of risk investors. Many LED companies have financing needs. How should investors choose potential companies? Mei Fu, a partner of Oriental Fuhai, is optimistic about companies with the following characteristics: a learning-oriented team, good at cooperating with others, strong market development ability, diligent and trusting, not to be comfortable with the status quo, not to give up.
Mei Jian believes that the technology that can sell products is good technology, patents, technology, market profit, "I prefer a first-class entrepreneurial team to have a second-rate idea, rather than a second-rate entrepreneur team with first-class idea".
At the same time, Mei Jian also told entrepreneurs how to choose investors, choose financial strength to provide continuous financial support, choose successful cases, choose excellent management team to provide good services, and choose the mechanism to be flexible and efficient.
What are the challenges facing the LED industry today?
Professor Luo Xiaobing of Huazhong University of Science and Technology pointed out that China's LED packaging industry has large capacity, but it is all small-scale trade. China's LED street lamps "have the largest production capacity, but there are no well-known brands."
Dr. Liang Bingwen pointed out that the challenges faced by China's LED lighting industry are mainly lack of talents, serious delays in product standard testing and supervision, lack of market transparency, lack of independent intellectual property rights, lack of high-quality capital and investors, and foreign companies investing in the mainland.
Philips Zong Mingcheng believes that the challenges faced by LED lighting are cost performance issues, improvement of light efficiency, quality of lighting systems, establishment of standard systems, and development of new applications by leveraging LED advantages. Zong Mingcheng pointed out that the standard should minimize the performance requirements, because solid-state lighting technology is developing rapidly.
Dr. Zhang Xiaofei, a high-tech LED, pointed out that the ten cities have made China a testing ground for global LED street lights. The success of “Ten Cities and Ten Thousand Cities†will affect the future direction of China's LED industry. According to a survey by the High-tech LED Industry Research Center, there are still many problems with the current LED street light technology. It is not recommended to launch a large-scale LED street light project.
Where will the future LED technology go?
Chen Daqing, director of the Tianjin Cityscape and Garden Management Committee, believes that promoting the improvement of light efficiency is the key to technological development. The light effect of LED light source is the starting point and driving force of LED industry development, which directly affects the energy saving rate, and also affects the government's determination, and affects the investor's recycling cycle and operating profit. He shouted, "As anyone in the LED industry, you must be aware of: light efficiency, light efficiency, light efficiency."
Professor Fang Zhilie from Fudan University told the audience to optimize the existing structure, optimize the materials, optimize the process, and then optimize the combination to achieve 161lm/W, and the 2mm2 chip 350mA reaches 208lm/W. The commercialization problem is not big, but the efficiency is no longer Improvement requires new technological breakthroughs.
Fang Zhilie pointed out that the current main development trend of power LED package structure is size miniaturization, optical lens casting, thermal power path separation, thermal resistance minimization, planar patching, maximum junction temperature tolerance, and maximum luminous flux.
Fang Zhilie quoted the statement of the Journal of the American Physical Society as saying, "In principle, the LED is the final form of the lamp, and its development can and will continue until all power and color are achieved."
Dr. Wang Wei from the Semiconductor Lighting Engineering R&D Center of Tianjin Polytechnic University is optimistic about the future of intelligent lighting control technology. The intelligent lighting control system has the advantages of automatic and intelligent lighting through software technology without changing the hardware and wiring. At the same time, it can better ensure the uniformity of the lighting effect and prolong the service life of the lamp.
However, Wang Wei also believes that manual control also has certain advantages. "The contradiction between the certainty of lighting design and the variability of lighting demand can be solved by manual control. The manual control device is simple, reliable and flexible. It plays a role in energy saving. Manual control has a unique advantage in private space."
LED street light technology challenges
Since the launch of “Ten Cities and Ten Thousand Miles†in 2009, LED street lighting technology has become a hot topic. In this forum, senior street lighting design expert Guangdong Zhaoxin Xu Liancheng said that at this year's Guangzhou Lighting Exhibition, some companies are working hard on product development. The products produced are very gratifying.
For street lighting design, Xu Liancheng reminds the industry to consider the wind resistance problem, "Let your street lights really stand in the wind and rain." Nowadays, the heat dissipation design of many street lamps does not take into account the problem of air convection, which causes the heat to be not actually exported, reducing the life of the LED.
Xu Liancheng advocates modular design. He believes that modularization not only avoids the risk of high-power power, IP protection is easy to do, maintenance is as convenient as conventional street lights, greatly reducing the maintenance burden of enterprises.
Chen Haijun, chief engineer of Ningbo Liaoyuan, believes that white LED street lights can help improve road lighting safety. He believes that road lighting should not only consider central vision, but also consider the ability to detect surrounding targets. White light led street lights containing short-wavelength blue light are more conducive to human eyes to detect surrounding objects.
He also believes that "in terms of street lamps, it is the key to reduce the interface thermal resistance and reduce the air gap." "There are actually fine air pockets due to the inherent flatness of the material surface. Because of the large thermal resistance of the air interface, It is not conducive to heat diffusion, so it greatly increases the overall interface thermal resistance."
Chen Daqing does not recommend the use of high-power LEDs above 3W as the light source for road lighting. The reason is that high-power LEDs are inevitably accompanied by the formation of large currents, which cause large heat and increase light decay. He told the participants that “the high-power integrated modules produced by several companies in China have achieved a luminous efficiency of more than 130Lm/W, the highest is close to 150Lm/W, and the temperature is controlled at around 50°C. In the second half, it reaches 160Lm/W. The above is indisputable."
Luo Xiaobing pointed out that the heat dissipation problem of LED devices is a systematic problem. There are LED chip thermal resistance, interface material thermal resistance, diffusion thermal resistance, environmental thermal resistance, etc. "We should reduce all thermal resistance at the same time is the key to solving heat dissipation."
Luo Xiaobing believes that by developing multi-layer ceramic technology and achieving integration and multi-function of LED packaging, reducing the size of LED packaging system and reducing packaging cost are the main trends of CoB technology.
Launch China CALiPER test report project
In this forum, the China CALiPER project was officially launched. CALIPER is an LED luminaire test project conducted by the US Department of Energy to provide objective data on SSL luminaires for the society and to guide related research and development activities. At present, there is no test project for LED lighting system in China. In order to promote the healthy development of the industry, Gaogong LED Industry Research Center decided to jointly launch China's CALiPER project with China Testing and Testing.
Dr. Zhang Xiaofei, director of the High-tech LED Industry Research Center, said that the current quality of LED lamps in China is uneven, which makes the public unable to correctly understand LEDs. Some of the inferior products of enterprises have tarnished the image of LED light sources in the minds of consumers. We hope to guide the healthy development of the LED industry through a series of testing activities. In addition, many companies currently have exaggerated information in their product specifications, which makes companies that provide real information suffer and even have to follow suit. We hope to curb this behavior through the project.
Hua Sheng test director Li Sheng pointed out that this project is not for profit, we will do it as a social responsibility. The cost of sample purchase and the cost of testing are borne by China Testing, which is included in the cost of corporate social responsibility, and also seeks corporate sponsorship and government funding.
