Tang Guoqing: Rational Thinking LED Hot Wisdom Choice LED Light
LED is everywhere! How to treat heat? Tang Guoqing pointed out that the current four hot spots of LED include: 1, listing heat; 2, fund heat; 3, investment fever; 4, market fever.
At present, the LED industry is booming. Although it has been cold since the beginning of this year, indoor lighting has become a hot spot in the development of the LED industry. Tang Guoqing believes that the four major areas of LED success include: landscape lighting, backlighting, automotive lighting and low pole lighting. In terms of landscape lighting, Tang Guoqing showed the audience the products of the CREE chip used in the Beijing Olympics and Shanghai World Expo. In the field of backlighting, LED backlights, mobile phones, mini-notebooks, monitors, and televisions will increasingly use LED backlights. Although LED lights were used in automotive lighting in 2008, with the continuous maturity and improvement of LED technology, Tang Guoqing believes that more models will adopt LED lighting in the future.
At the meeting, Tang Guoqing analyzed four common problems of LED lights: 1, brightness attenuation; 2, color area drift; 3, glare halo; 4, gradually see dead lights. He pointed out that LED's main attack high ground is still in the field of functional lighting, mainly including garden lighting, commercial lighting, tunnel lighting and road lighting. He believes that green lighting products must have high comparability, otherwise there is no way to promote energy saving without environmental protection. Finally, he concluded that LED must become the four basics of lighting mainstream: 1, LED is efficient, energy-saving, environmentally friendly; 2, LED's performance is very imaginative, lighting will be all-round, 360 degrees; The existing ones are mercury-containing and toxic; 4, the needs of the Earth, the green industrial revolution will certainly start from green lighting.

Xiao Chengfeng: Inspur Huaguang--Building LED to illuminate the core of China
At the meeting, Xiao Chengfeng proposed the development of domestic LED chip companies. Under the global low-carbon economic tide, the development of LED conforms to the trend of energy conservation and consumption reduction. China's competent authorities at all levels have also introduced corresponding support policies to promote China's semiconductor industry to become bigger and stronger, and the scale of investment continues to expand in the industrial chain. In all aspects, the scale of investment in epitaxy and chips is larger, which is due to the development and expansion of LED application fields. However, how can domestic LED chip companies further develop and grow in this tide? Xiao Chengfeng analyzed the status quo of LED in the four application fields and the advantages and disadvantages of domestic chip companies, and believed that the technical strength of domestic LED chip companies is the most practical. The development idea is: landscape lighting - commercial lighting - general lighting - (outdoor road lighting, backlight).
Then, he introduced the positioning and development ideas of Inspur Huaguang's LED industry. Inspur Huaguang is the only company in China that has independent research and development capabilities, masters LED epitaxial core technology, and has a complete industrial chain. Currently, there are good results in the four major application areas. In the future, Huaguang will continue to improve the cost performance of lighting and display products, expand the advantages achieved in the field of lighting and display, and make breakthroughs in indoor lighting to create LEDs to light the core of China!

Gaogong LED Zhang Xiaofei: LED industry inventory in the first half of 2010
First of all, Zhang Xiaofei took stock of the top ten hot topics in the LED industry in the first half of the year, that is, "the price of the chip has risen against the historical trend?", the ten cities are no longer hot, the two LED companies are listed domestically, and "multiple standards are introduced to the industry." The chaos is still not over," EMC spoiled the LED industry, LED TV penetration exceeded expectations, optoelectronic industry parks were tight, overseas markets accelerated the popularization of LED lighting, high-power chip light effects to achieve new breakthroughs, traditional lighting accelerated 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. When 3D TV is being promoted with great fanfare, LED TV has quickly completed its preemption of the 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. At present, the optoelectronic industrial park has fierce competition for investment, and the “war for investment†in various industrial parks is extremely fierce. The government introduces “hidden rules†and various localities are competing to introduce attractive policies.
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.
A new breakthrough in high-power chip light efficiency, CREE announced that its high-power chip achieved 208lm / W @ 350mA. In the past few years, the efficiency of LED production chips has increased at a rate of 15 lm/W per year. The efficiency of high-power chips in 2010 is expected to reach 30 lm/W. Since most chip manufacturers use sapphire substrate technology, the light efficiency of this technology route is growing slowly.
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: LED and natural lighting
At first, humans only needed to be able to illuminate the lighting. Later, humans began to consider health issues. Whether to save electricity, save money, protect the environment, and strobe-free have become human requirements for lighting. Nowadays, people have a higher level of pursuit for lighting. People have begun to pay attention to whether lighting meets the physiological and psychological requirements of human beings, and pursues the realm of harmony between light and environment--natural lighting.
Zhong Qun believes that with the LED system's high luminous efficiency, intelligent system control of energy-saving methods and environmental protection, in this lighting war, as the cost of LED lamps continues to decrease, LEDs will eventually replace incandescent lamps, fluorescent lamps, and high voltage. Traditional lighting fixtures such as sodium lamps.
Zhong Qun analyzed several basic elements of natural light illumination. Through the LED's advantages and disadvantages for health lighting, he believes that LEDs need to be improved in glare, uniformity, color temperature and color rendering. In terms of energy saving, life, glare, light distribution, color development and color temperature, the requirements for healthy lighting are higher, which is a greater challenge for LED devices.
At the meeting, Zhong Qun also introduced the SMD TOP LED products of Zhongjing Kechuang, with higher luminous efficiency, full range of power, long life, whiter white light, full range of color temperature, high display value, low thermal resistance and spot color. Uniform and other characteristics.

Chen Xu: Ultra-high power lighting grade LED metal packaging technology
First, Chen Xu analyzed the current status of the LED lighting application industry. At present, more and more lighting industry and technology industry elites have invested in the field of LED lighting, which has greatly promoted the development of the LED lighting industry. At the meeting, he pointed out the reasons for the current difficulties in LED lighting applications: 1. The light source is unstable and the life is short; 2. The power quality is poor and the fault is many; 3. The light distribution is difficult and the exposure is strong; 4. The production process is complicated. The input cost is high, the time is long, and the yield is low.
Through the comparative analysis of light efficiency, thermal conductivity, illumination distance, light distribution, structural characteristics and lighting applications of LED products with different packaging processes, Chen Xu believes that the all-metal embedded integrated package is more integrated than the thin substrate integrated package and single crystal package. Do it better.
Chen Xu briefly described the light source type, light source characteristics, light source heat conduction diagram, lens, collar, copper bracket, aluminum base and light decay of Xinli Optoelectronics LED products. Finally, Chen Xu 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.

Wang Tao: Indoor Lighting - Crown of the LED Industry
Any technology can only make sense if it is combined with social life. In 2009, the number of domestic lamps reached 18 billion, including 2.7 billion incandescent lamps and 3.5 billion fluorescent lamps. The market space is huge. The development of indoor lighting can make semiconductor lighting better serve the social life. At present, CREE's LED laboratory light efficiency has reached 208Lm/W, and the LED products on the market have a luminous efficiency of 140Lm/W and a luminous efficiency of 45%. From a technical point of view, indoor lighting is more suitable, more mature and economically more rational for semiconductor lighting technology. In addition, LED lighting fixtures do not contain mercury, lead and other pollution elements, no pollution to the environment, can truly achieve low carbon environmental protection. Moreover, it has no ultraviolet radiation, infrared radiation, color temperature, color rendering index controllable, and is very suitable for human visual requirements. Wang Tao believes that indoor lighting will be the crown jewel of the LED industry.
Next, Wang Tao introduced the research and development achievements in the LED industry in recent years. In terms of LED bulbs, they have developed 10 products in two sequences of AC and DC, forming a series of products for indoor lighting. The luminous flux of DC and AC products from 50Lm to 700Lm will completely replace incandescent lamps to meet the daily lighting needs, especially the large-volume, wide-angle 40W, 60W bulbs show good vitality. It can be widely used not only in large, medium and small lighting environments, but also in semiconductor indoor lighting, which basically meets the needs of the market.
"In terms of indoor lighting, we have a good industrial base." Wang Tao said. He analyzed that based on the industrialization of underground lighting, the industrial production conditions of energy-saving lamps, and the performance of LED bulbs superior to international famous brands, and through the cultivation of talents and extensive cooperation with CREE, a good industrialization foundation has been established.
At the meeting, Wang Tao summed up their research on the high point of energy-saving lamp technology, which can be summarized as research on optical path design, heat dissipation technology, drive circuit technology and production process.
Finally, Wang Tao briefly analyzed the cost of LED indoor lighting, and believed that the industrial environment determines the speed of development, and the development environment must be optimized. To be the "Lenovo" of semiconductor indoor lighting, to promote the industrialization of LED indoor lighting, energy saving and emission reduction, benefit the country and the people!
