Career China Tang Guoqing: Ten Reasons for LEDs to Change Lighting
Tang Guoqing, general manager of Career China Market, believes that LED is a meaningful thing. He cited ten reasons to fully demonstrate LED lighting changes and share with the industry how to do LEDs.
Tang Guoqing said that compact fluorescent lamps are beautiful mistakes and energy saving is not environmentally friendly. As the decision-making level changes, the opinions of experts begin to change, the public's ideas change quietly, the influence of major projects increases, the space for the promotion of traditional lamps is narrow, the level of LED technology advances leaps and bounds, the price of LED lighting products declines, and the trend of market competition tends to Standards and standards have been accelerated and established, and the era of green lighting has arrived. LED is changing lighting, and the green industrial revolution is coming.

Najing Optoelectronics Beam Bingwen: Discussion on Low-cost Solution for Semiconductor Lighting
Liang Bingwen, chairman of Suzhou Najing Optoelectronics Co., Ltd. analyzed the development of the semiconductor lighting industry and shared solutions on how to reduce costs. He believes that semiconductor lighting can be widely used in real life in promotion, and the most important issue is cost. China is one of the largest LED downstream product manufacturing bases, with huge market potential, but facing the shortage of LED talents, rising raw materials prices, patent troubles, and serious lags in standards. China's LED epitaxial chips are mainly low-end and high-quality epitaxy. The key technology of the chip has not yet been fully grasped. At present, large companies have begun to enter LED, and high-quality capital has begun to intervene in the LED market.
Liang Bingwen pointed out that the key to the development of the semiconductor lighting industry is market, technology and cost. He believes that the light effect has not yet reached the top and can theoretically exceed 300. LEDs should be used in general lighting, and costs still need to be reduced by a factor of three to five. In terms of talents, if 80 companies in China can control MOCVD, and each chief engineer can only control 5 MOCVD calculations, the total number of engineers required for hundreds of MOCVD in China is obviously insufficient.

Zhongjing Kechuang Zhongqun: How to design LEDs suitable for lighting
Dr. Zhong Qun, general manager of Shenzhen Zhongjing Kechuang Optoelectronics Technology Co., Ltd. pointed out that with the continuous improvement of LED lighting technology, people's requirements for LED lights are getting higher and higher. From the very beginning, it can light up (salvation problem)-->Power saving, saving money, environmental protection, no stroboscopic (health problems)-->Meet the physiological and psychological requirements of people, and achieve a harmonious state of light and environment (enjoy problem). LED lighting is constantly evolving, facing the war of traditional and LED lighting. At the same time, Zhongqun summarized the energy saving: 1. The energy conversion efficiency of the LED device is high; 2. The lower forward voltage; 3. The high light efficiency of the package; 4. The junction temperature is low under the working condition; 5. The light distribution is reasonable and effective. High illumination rate; 6, high power efficiency; 7, intelligent control. Finally, Zhong Qun conducted a comparative analysis of LED and natural light illumination.

Nanjing North Huihua Sangxia: Open the veil of the LED driver
Sang Xia, Marketing Manager of Nanjing North Huihua Optoelectronics Co., Ltd., mainly opened the veil of LED driver from the following four aspects: First, the distribution of the industry chain; Second, the terminal application requirements; Third, the current situation of the drive analysis; Fourth, the driver manufacturer's recommendations.
Sang Xia pointed out that the driver is in the downstream packaging and application products in the upstream, midstream and downstream industry chain, and shows the cost proportion and maintenance cost of the driver in the outdoor lighting products. Terminal application requirements are described in terms of safety regulations, radio frequency interference, electromagnetic interference, and the operating ambient temperature of the product. The current status of LED drivers is mainly analyzed from the aspects of temperature rise control, voltage range, drive efficiency and design quality.
Finally, she presented four main recommendations for LED driver manufacturers:
1. Consider the overall design and material selection quality (chip, drive, heat dissipation);
2. Before designing the structure of the lamp, consider the rationality of the power supply cavity;
3. When the LED is arranged, pay attention to whether the electrical requirements are feasible;
4. Pay attention to wiring and grounding when installing the project.

Liu Leishi, Nanjing Street Light Management Office: Planning for LED Demonstration Application Project in Nanjing
Liu Lei, chief engineer of Nanjing Street Light Management Office, introduced the research and use of LED test energy-saving and emission reduction technology in Nanjing Street Lights. He pointed out the bottleneck of LED street lamps: At present, compared with high-pressure sodium lamps, high-power LED lamps have no obvious energy-saving effect in road lighting. LED street light application standards are lacking, no generality; LED street lights are electronic products, life fluctuations are large, maintenance is difficult; technical bottlenecks are difficult to break; economic returns are poor.
Liu Lei actually put forward some suggestions to continue to promote the application of state-subsidized high-efficiency lighting products in urban functional lighting - high-pressure sodium lamps; to promote the use of LED features in landscape lighting; to expand the industrial chain to the upstream of LED street lights; to track the latest development technology of LED Try it within a certain range.
Liu Lei actually raised his own doubts, how to realize the social benefits and economic benefits of LED street lamps; why LED can quickly occupy the market in landscape lighting; where is the bottleneck of large-scale application of LED street lamps; can you do LEDs with funds; road lighting needs How LEDs develop.

Philips Lumileds Wu Peng: LUXEON Rebel - setting a new benchmark for LEDs quality
Wu Peng, technical plan manager of Philips Lumileds China, pointed out that Lumileds will have more than 100 million US dollars of research and development investment this year. The company's largest customer is Apple. He believes that the future 1W LED module is the development trend of backlight. In 2008, the penetration rate of LEDs to lighting was 7%, and in 2020 it will reach 75%. At present, the industry chain mainly faces the following challenges: the public has little understanding of LEDs, and there is still no good solution for color consistency. There is still a certain gap in quality compared with traditional light sources, and reliability is difficult to guarantee. How to simplify the design, how to improve the heat resistance of LEDs, and how to eliminate chromatic aberration. Lumileds is optimistic about the prospects of AC LEDs and will introduce AC LED products. The company's chips passed the ENERGY STAR certification and passed the LM-80 test.

Cai Ming pointed out that environmental requirements, government requirements, user demand for lighting products, the status quo of traditional lighting industry, the broad market prospects of LED lighting, and the feasibility of semiconductor lighting technology indicate why the traditional lighting industry should be transformed into the semiconductor industry. At the same time, he also reported on the future of the "Ten Cities and Ten Thousand Miles" LED lighting project in Yangzhou City, the completed part of the project and the LED street lamp intelligent dimming system, the indoor LED lighting intelligent integrated system and the indoor intelligent dimming system. Related situation.
Then he said that the problems and explorations of the transformation of traditional industries into the semiconductor industry are explained in the following four aspects: 1. The change of the sales mode of traditional lighting products; 2. The quality of LED lighting products in the market is uneven and lacks effective supervision; 3. Subject to the technical development and cost factors of the core chip; 4. Protection of the product patent of the creative enterprise.
Finally, it is believed that the development enterprises of the semiconductor lighting industry hope that the country should increase its support in the application of semiconductor lighting; further improve the EMC energy management model policy; and increase the support for the training and support of semiconductor lighting-related talents.
