Zhang Xiaofei: 2010 China LED Industry Report

Zhang Xiaofei, director of the High-tech LED Industry Research Institute, gave a report on the 2010 LED industry in China. First of all, Zhang Xiaofei took stock of the top ten hot topics in the LED industry in the first half of the year, namely, the price increase of the chip, the heat of the ten cities is no longer hot, the two LED companies are listed domestically, and the “multiple standards have become unsettled in the industry”. Industry, LED TV penetration exceeded expectations, optoelectronics industry parks are attracting investment, overseas markets accelerate the popularization of LED lighting, high-power chip light effects to achieve new breakthroughs, traditional lighting accelerates to LED lighting.

Regarding the price increase of the chip, he analyzed the price increase phenomenon and the reasons, and believed that the price increase of the chip will continue until the second quarter of next year, after which there will be a continuous decline, and the situation of continued decline in chip prices after next year will continue. . Last year, the ten cities and cities were still in full swing, but this year they were cold and the heat was no longer. The so-called "Ten Cities and Ten Thousand Miles" goal has been difficult to achieve, and the installation of LED street lights will increase steadily and slightly this year and next.

With the high-profile listing of Guoxing and Ganzhao in China, 43 LED companies have completed the share reform. Zhang Xiaofei believes that the situation of LED companies' stock price surge has ceased to exist, and the market and investors are also restoring rationality. Although there are a number of standards currently in place, the confusion in the LED industry is still not over. Coupled with the full bloom of local standards in the first half of this year, China's LED standards have been in a state of long-term management. In essence, local standards hinder the development of industries across the country.

In the first half of this year, some EMC cases were launched in various places, with the largest number in Guangdong. At present, EMC is facing many obstacles. Zhang believes that EMC will still develop in the process of exploration, and with the advancement of LED technology, price decline, and various systems, the feasibility will gradually increase. 2010 is the year of LED backlight TV explosion, LED backlight TV is regarded as the mainstream of the future TV market. GLII predicts that the market share of LED-backlit TV will increase from 7% in 2009 to 35% in 2010. It is estimated that China's domestic LED TV manufacturers plan to produce 5.5 million units in 2010.

The overseas market has accelerated the popularization of LED lighting. As the purchasing power of developed countries will be strong, the difference between traditional lamps and LED lamps in developed countries is smaller than that of developing countries. They are at the forefront in popularizing LED lighting. GLII survey data: In the first quarter of 2010, China's LED application output value was 19.9 billion yuan, a year-on-year increase of 42%. The surge in overseas demand is an important reason.

Traditional lighting accelerates the shift to LED lighting. The scale of traditional lighting has increased from 62.5 billion US dollars in 2009 to 96.8 billion US dollars in 2010, and is expected to reach 154 billion US dollars in 2012. LED lighting from $2.5 billion in 2009 to $3.2 billion in 2010 is expected to reach $5.29 billion in 2012. From 2009 to 2012, the compound annual growth rate will reach 28.5%.

Zhong Qun: 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.

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; the light distribution is reasonable, the effective illumination rate High; 6, high power efficiency; 7, intelligent control. Finally, Zhong Qun conducted a comparative analysis of LED and natural light illumination.

Gu Zongjun: Ultra-high power lighting LED packaging technology

Gu Zongjun, Marketing Director of Jiangsu Xinli Optoelectronics Co., Ltd. outlined the current status of the LED lighting application industry. As an emerging field, many lighting industry colleagues have encountered some difficulties in the process of manufacturing LED lamps. He summarized that the factors that hinder the promotion of LED lighting mainly include: 1. unstable light source and short life; 2. poor power quality and many faults; 3. difficulty in light distribution and strong glare; 4. complicated production process and high input cost. It takes a long time and the yield is low.

Through the comparison of LED products in different packaging processes, Gu Zongjun introduced the technological features of Xinli Optoelectronics LED products, including: light source, lens, collar, copper bracket, aluminum base and light decay. Finally, Gu Zongjun also introduced a principle and application of ultra-high power lighting level LED metal packaging technology, and showed Xinli Opto's road light series, flood light series and explosion-proof light series products.

Zhu Ming: Breakthrough and innovation of LED products

Zhu Ming, manager of CREE South China Lighting Business Department, pointed out that Career has invested in two production bases in Huizhou, indicating that Cree attaches great importance to the Chinese market. He also briefly introduced the LED products made of CREE chips in the Beijing Olympics, Shanghai World Expo and fast food chain stores.

Zhu Ming said that energy-saving lamps contain harmful substances such as mercury, which cause great pollution to the environment. According to China's annual energy saving lamp of one billion, it will pollute 574 billion tons of water. However, LED lighting is absolutely environmentally friendly. CREE has been committed to promoting the field of LED lighting. The price of LED lamps will be lower and lower. It will be a trend to buy an LED bulb for RMB 50.
