Xiao Congqing, technical director of Graymont Technology, said that technology can not be accumulated in a day or two, so it is necessary to do a lot of work on technology. Otherwise, there will be no more money in the LED industry.

Participants highlighted the current state of the art in the LED industry, including phosphors, LED drivers, innovative COB light source technology, new SMD LED packaging and new test technologies, and future design trends for LED lighting. The leaders of many LED companies participating in the conference answered the questions about the new LED technology.
Dr. Zhang Xiaofei, CEO of Gaogong LED, pointed out that in the winter of the LED industry, corporate competitiveness is particularly important. Competitiveness includes team management but the most important is technology. “If there is no technology for LEDs, what is the difference between you and traditional lighting? How do you compete with traditional lighting?â€. 
Gaogong LED CEO Dr. Zhang Xiaofei 
“In 2012, Shanxi Guangyu did the most in terms of technology development, including the design of the light source, including the design of the tunnel light, including the application of modular application. It is modularized and assembled into various modules. It is very effective for cost. The way.†Xu Min, deputy general manager of Shanxi Guangyu Lighting R&D, said that modularity has many advantages, and the cost advantage for producers is self-evident. Different modules can design different products. Because the size of the light source module is small, many products with different shapes can be made. On this basis, different light distribution designs are made, thereby improving the design efficiency of the lamps. At the same time, modularization is also very convenient for enterprises to organize production management. 
Xu Min, Deputy General Manager of Shanxi Guangyu Lighting Research and Development
When answering the questions from the participants, Xu Min said that the standardization of lamps and lanterns is a relatively long process. At present, local standards are being made in many places, and national unified standards are being formulated. Standardization is also pushing the standard while pushing luminaires and modularity.
Xiao Congqing believes that the modular concept is a good direction. There are also many modular concepts in other industries. Modularization should be a mass-oriented approach, but it is difficult to do without standards, so this is also a long one. path of.
New technologies are emerging
Professor Jing Chongguang from Shanghai Jingfeng Mingyuan Semiconductor said that indoor LED lighting should be affordable and affordable LED lamps. The indoor lighting market is a huge market, and the world needs LED lamps with better cost performance. 
Prof. Yan Chongguang, Shanghai Jingfeng Mingyuan Semiconductor
"Currently, the common schemes for indoor LED lighting drive power supply are resistance-capacitor buck or stabilized diode, PSR isolation switch constant current drive, non-isolated switch constant current drive. Recently, the new technology is high-voltage linear constant current drive.
Researching rare earth high-tech summers when talking about the trend of LED phosphor technology in 2012, phosphors as a segment of the field, at least 30 companies are currently doing, in the case of poor LED development, companies are promoting Cost-effective, the current domestic market share of more than 35%, next year should have the opportunity to reach about 50%, breaking the relative monopoly of foreign products. 
Have research rare earth high-tech summer
"The new technology of remote phosphors in 2012 is not particularly good, including Intermec also spends a lot of effort to promote. The same is true for rare earths, and the future is worth looking forward to." Summer believes that with aluminate fluorescence With the rapid development of powder, silicate phosphors are likely to continue to decline in the future. Nitride phosphors have great potential in the future, but there is still much room for improvement in terms of technology and cost. 
Dr. Gao Jiwei, Technical Director of Hangke Optoelectronics
Dr. Gao Jiwei, Technical Director of Hangke Optoelectronics, said that with the development of LED applications, there are many requirements for packaging. COB LED packaging technology is the mainstream technical solution for LED general lighting that is recognized by domestic and foreign industry. COB packages have many advantages in terms of heat dissipation, overall illumination, and cost. The key to the future development of COB depends on the market, and it needs to continue to mature in technology and technology, while reducing costs and improving cost performance. 
Li Pengfei, deputy general manager of Tongfang Semiconductor of Nantong, introduced the current development technology of LED epitaxial wafers and chip technology. When talking about the development of Tongfang Semiconductor's LED chips, Li Pengfei said that Tongfang has two major factories in Beijing and Nantong, mainly engaged in LED epitaxial chips, and also involves backlight modules and the entire application. The monthly production capacity of LED epitaxial chips is 180,000.
