The wide application of LED in urban landscape lighting, display screen, road traffic and white light lighting has enabled the production capacity of LED industry bases in Shenzhen, Xiamen, Dalian, Shanghai, Nanchang and Shijiazhuang to improve. As another important base for the industrialization of national semiconductor lighting projects, Tianjin has become a must for foreign and domestic LED companies to enter the Bohai Rim region. The "5th LED Industry Theme Summit Forum" hosted by Gaogong LED and Tianjin Dongli District People's Government was held in Tianjin recently. It is undeniable that the Tianjin LED industry seems to be slower than other parts of the country. The forum will greatly promote the development of the LED industry in the Beijing-Tianjin region and even in North China.
Tianjin expects LED to come on
Tianjin is vigorously developing new materials and new energy industries, and LED is their key development direction. Zhang Youhui, secretary of the Dongli District Party Committee of Tianjin, said in an interview that the district is preparing to set up venture capital to develop high-tech industries. Zhang Youhui believes that it should start from cultivating and introducing leading talents. The forum was held in the district to help promote the investment of LED projects in Tianjin Dongli District.
Guan Baiyu, deputy inspector of the Electronic Information Department of the Ministry of Industry and Information Technology, said in the forum that the Ministry of Industry and Information Technology will further strengthen the cooperation and interaction with local governments, pay attention to the development of Tianjin's electronic information industry, and promote the cooperation with industry colleagues. Advances in the semiconductor lighting industry.
Dr. Zhang Xiaofei, CEO of Gaogong LED, believes 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 also China's first LED city demonstration zone. At the same time, Tianjin Polytechnic University opened China's first light source and lighting professional, in order to strengthen LED enterprises in China, especially in the north. Communication and cooperation, we deliberately set the venue of the 5th China LED Industry Theme Summit Forum in Tianjin." Zhang Xiaofei said.
During the forum, the signing ceremony of Tianjin Dongli National Semiconductor Lighting Engineering High-tech Industrialization Base was held. Nine enterprises signed a letter of intent for investment cooperation, and 56 enterprises signed the “Development of Low-carbon Economy†to jointly promote Tianjin Binhai. "Proposal for the construction of semiconductor lighting high-tech industrial base". Whether Tianjin LED development can be followed is worth looking forward to.
Launch China CALiPER 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, the High-tech LED Industry Research Institute decided to jointly launch China's CALiPER project with China Testing and Testing.
Gaogong LED Dr. Zhang Xiaofei 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 eyes of consumers. “We hope to guide the healthy development of the LED industry through a series of testing activities. In addition, many of the current product specifications in the company list some exaggerated information, which makes the companies that provide real information suffer and even have to follow suit. We hope to curb this behavior through the project." Zhang Xiaofei said.
Li Sheng, director of China Measurement and Testing, pointed out that this project is not for profit. "We will do this as a social responsibility. The sample purchase cost and testing cost will be borne by China Testing and will be included in the cost of corporate social responsibility, and will also seek corporate sponsorship and government funding support." Li Sheng said.
EMC brings opportunities and challenges
With the deepening of the “Ten Cities and Ten Thousand†semiconductor lighting project, a brand new term “contract energy management (EMC)†is gradually becoming familiar. Sun Jianhua of Destar Optoelectronics Lighting Technology (Shenzhen) Co., Ltd. believes that it should be government-led and gradually explore the EMC model in line with China's national conditions, so that private capital has the opportunity to 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.
Academician of the Chinese Academy of Sciences Yao Jianwei: High-speed and stable development of China's LED industry
The third climax of the information industry's entry into development, the first is the computer, the second is the Internet, and the third is the Internet of Things. We have fallen behind in the first two stages of development, and we must be ahead in the third stage of development. In the third stage of development, there are several new industries and technology areas worthy of attention, such as: new energy, new optoelectronics industry. LED should be said to be a jewel in the field of information industry. LED is mainly used in lighting, display and other fields. The LED industry is a sunrise industry in the information industry. Although there are still many technical problems to be solved, its development prospects are obvious. Internationally, both academic and business circles are optimistic about LED development. The LED industry is highly valued by government departments, business circles and academic circles.
In the optoelectronics industry, there are two stars, one is solar cells and the other is LEDs. These two industries have attracted a lot of attention at home and abroad. There are still many problems to be solved in the development of the LED industry, technical problems, industrial problems, and so on. The LED industry should have high, fast and stable development characteristics. “High†means high starting point, including technical aspects and industrial structure; “fast†means speeding up the pace, speeding up the pace and accelerating integration; “stable†means steadily moving forward. Orderly development, can not develop blindly.
Chen Yansheng, Chairman of China Lighting Industry Association: LED lighting "heat" has advantages and disadvantages
In recent years, the use of LEDs in lighting has been described as "hot" in one word. "Hot" is reflected in a few "more". First, the government at all levels pays more attention to it. Second, there are many enterprises entering this field. Third, the media pays more attention. The fourth is the involvement of venture capital funds. These are summarized as "hot." ".
In recent years, from the central to the local, the development of LED heat is not diminished. I think this kind of heat is not completely bad. From the perspective of enterprises, whether it is a traditional lighting enterprise or a semiconductor enterprise, it has nothing to do with LED. Enterprises are paying attention to LEDs, and they are all entering the industry. This also reflects "heat" from one side. From the perspective of venture capital, many venture capital companies are considering how to further invest in the LED field. Both domestic and foreign venture capitalists believe that the field of LED lighting is a very good investment area. There are advantages and disadvantages to "heat". There are so many people paying attention to the LED lighting industry is not a bad thing but a good thing. However, the practitioners in the LED industry should be calm, consider the problem should be rational, reduce blindness, and increase scientific and rational. We know that the application of LED street lamps in China is surging, and the number of enterprises exceeds that of traditional street lamps. Why is this phenomenon? Because street lamps are government subsidies, companies are not facing the market but the mayor. From the long-term development of the entire industry, such development is not very beneficial to the LED industry. The government should formulate more policies to create a good environment for research and development and attract investment. How companies are involved in the LED lighting market deserves serious consideration.
Zong Mingcheng, Director of Solid State Lighting Standardization, Philips Lighting Asia Pacific: LED lighting system is still cost-effective
With the development of the economy, light is not only limited to illuminating, but also to be well-lit and comfortable, which is also a basic requirement in the field of lighting. Green lighting is the driving force for innovation. In the past 10 years, LED lighting technology has emerged and LED lighting is facing opportunities for development. The industrialization of high-power and high-brightness white LEDs has brought a wave of innovation to the lighting industry. Industrialization here is very important. In addition, products must be stable and reliable. The LED light source (light bulb) market is expected to reach 50 billion yuan by 2015, which is also due to the rapid development of LED technology. In the past 20 years, the light output of LEDs has increased nearly 20 times and continues to grow. At the same time, LED costs have been reduced 10 times in 10 years. LED cost performance is constantly improving, so LED lighting technology is very promising.
The LED industry is also facing challenges while it is developing rapidly. The performance price ratio of LED lighting systems is still high, and mass production is critical. In addition, LED competitors include energy-saving lamps, high-pressure sodium lamps, ceramic metal halide lamps, electrodeless lamps, etc. These lamps are also very efficient, especially at a low price. Therefore, when developing LED street lamps, it is necessary to objectively analyze and find a way out. This is an important point. In addition, the reliability and stability of the LED lighting system are very important. At the same time, the LED lighting industry chain needs to be optimized. At present, the LED related standardization system is still not perfect. It is necessary to give full play to the technical advantages of LED and break through the limitations of traditional lighting, such as intelligent control. , embedded, etc.
Yang Lan, senior sales manager of OSRAM Opto Semiconductors North/Southwest Region: Pay attention to light pollution when using LED
At present, the luminous efficiency of LEDs has been 5-8 times higher than that of incandescent lamps. The efficiency of LEDs in the future will be about 10 times higher than that of incandescent lamps. Our prospects for LED as a light source are very promising, and its market application prospects are also very extensive.
In terms of ecological, economic and social aspects, LED can achieve a triple win. Ecologically, LEDs reduce carbon emissions. From an economic perspective, LEDs are the main force driving profit growth. From a social perspective, quality of life is improved and energy costs are reduced. At present, the Chinese market needs to pay attention to the fact that LEDs cannot be used in order to use LEDs, and attention should be paid to the problem of light pollution.
In the future, the LED market is expected to grow from US$337 million in 2007 to US$1.647 billion in 2012, with an average compound annual growth rate of 37%. Among them, architectural lighting will be the dominant application area during the forecast period, accounting for 2012. 42% of the market, in addition, commercial lighting is also worthy of attention.
Applications and performance improvements continue to drive the LED market, and LEDs have focused on improving performance over the past few years. As LED performance increases and prices drop, LEDs will have a wider range of applications. Also, be aware that improving efficiency cannot be at the expense of life.
Chips, phosphors, packages, etc. all affect LED performance. Every year, OSRAM invests heavily in research and development in chips and phosphors. LEDs need to accumulate and require subsequent investment. China needs to pay attention to the accumulation and breakthrough of technology.
Tang Guoqing, general manager of Cree China Market: Pay attention to the problem of LED lamp power supply
Now we are talking about LED lighting has been completely different from the previous one. At present, the number of enterprises that make LED street lamps is increasing from the number of traditional lighting companies, not reducing, indicating that everyone is optimistic about the development of LED street lighting applications. Choosing lights and making lights is still a very difficult task in the industry. Successfully making LED lamps is not only a problem of light sources, power supply, high temperature resistance, waterproofing, etc., especially power supply problems have a great impact on LED lamps, and special attention is required. At the same time, LED applications are becoming more widespread, and new applications will continue to emerge. LEDs are changing China, and this change includes government orientation, market demand, and awareness. Concept awareness is very important, and the deepening of low-carbon, energy-saving and environmental protection concepts is the biggest advantage of LED development.
Cree attaches great importance to the Chinese market. In November last year, Cree's chip factory invested in Huizhou was under construction. In July this year, white LED chips will be supplied. Cree Lab's latest research and development results, high-power white LED light efficiency has reached 208lm / W, 350mA, only 20,000lm / W two months ago, the technology progress is very fast, although the laboratory data, but also very surprised. Currently, Cree's chip production level is 132lm/W, 350mA (single chip high power XPG).
