Expert analysis LED industry hot topic

June 10, 2010, sponsored by the high led "sixth China LED Summit Forum in Guangzhou, China import and Export Commodities Fair held a grand hall. The report covers topics such as talent, market, investment, technology, EMC model and other current LED industry hot topic.

CREE China market general manager Tang Guoqing, in the photoelectric technology Co., Ltd. chairman and general manager Zhang Jiuliu, general manager of the company Gong Weibin REFOND optoelectronics Co., Fujian zhongkewanbang Au Optronics Co chairman He Wenming, Le Lei photoelectric technology (Shanghai) general manager, deputy general manager of limited company chairman and general manager Xiong Kecang, Zhang Hui TCL, topunive science and Technology Co Ltd electrical lighting division general manager Li Yimin, Professor of Fujian optoelectronics industry association senior engineer Ye Rongnan, cubic lawyer Deng Yao, Zhang Ziqi, general manager of Songda Gabriel Zhonglong Communications Technology Co. Chen Bin, LED Engineering Research Institute (GLII) Dr. Zhang Xiaofei and other experts have done a wonderful theme of the report on the forum.

The sixth summit forum attracted more than 600 participants, mainly from foreign LED and lighting companies senior management, technical experts, investment institutions, investment managers and government related functional departments.

Five elements of LED driven lighting revolution

What changes will LED bring to China? Tang Guoqing believes that the transition from traditional lighting to LED lighting, has spread in the world. LED efficiency has reached 131 lm/W, the second half of this year is expected to reach up to 161 lm/W, LED drive lighting change has become a reality, we should think about how to promote the development of the LED industry, do a good job with LED, LED. March 2010, a well-known Japanese companies to stop the production of ordinary incandescent bulb business, the full expansion of LED lighting business is also a strong evidence.

The organic combination of traditional light source is weak, usually from the outside of the building and building lighting or due to scattering, light will hit the unnecessary waste caused by local sources. The direction of the LED is relatively strong, and the two optical design can be light to the desired place to reduce unnecessary light pollution. In addition, another indispensable high color saturation is also LED advantages, LED through the red green and blue three primary colors into a bright and colorful picture of the modulation chip, become a part of the beautification of the city indispensable.

Tang Guoqing believes that LED can drive the lighting successful change in the following five factors: 1, environmental advantages, the use of green light real, to eliminate environmental hazards from the source; 2, high light efficiency, as the sustainable development of energy efficient lighting, imperative change; 3, good color, for people to create a more comfortable and more safe the high quality of life in the evening. 4, color Hyun, high color saturation of the screen is an indispensable part of city beautification; 5, strong flexibility, with more human design, comfort and lighting and lighting to enjoy beauty has become the new focus.

Traditional lighting and LED lighting war

High tech LED CEO Zhang Xiaofei in his speech, a profound analysis of the LED lighting and traditional lighting in the market and the status quo of the traditional lighting companies involved in the LED industry. Zhang Xiaofei pointed out that, LED lighting and traditional lighting of the war has just started, the next ten years will be a protracted war, or entirely in the hands of each enterprise, with the rapid expansion of the scale of LED lighting, LED lighting gradually replace traditional lighting is irreversible, time will always stand in the side of LED lighting.

Zhang Xiaofei believes that the traditional lighting companies with strong capital accumulation, strong production capacity, strong sales channels, LED lighting lighting enterprises can not ignore the traditional advantage of these LED lighting companies need to obtain capital, grasp the core technology, seeking to open cooperation strategy development.

Break through the bottleneck to accelerate the popularity of LED backlight

In the LED package, there are some bottlenecks in the field of lighting and backlight. REFOND general manager Gong Weibin pointed out that the high power LED lighting, high requirements for heat and light; and the backlight, mainly for consistency. But LED TV color rendering and reliability is the focus of consumer choice LED TV is mainly optimistic about its color performance. At the same time, for LED TV, a LED broken, the entire TV on the dark, which is a lot of domestic enterprises is difficult to climb the past hom. He believes that the solution is mainly to enhance the efficiency of light, heat dissipation, the distribution of phosphors and the development of high reliability materials.

Gong Weibin, general manager

Gong Weibin said that the thinner the phosphor coating, the higher the efficiency. From the packaging materials, we can see that the thermal resistance of the chip substrate material and solid crystal material has become the bottleneck of the whole LED thermal resistance. He also cited the advantages of eutectic flip chip technology, he believes that the eutectic process for high power LED, due to the reduction of the overall thermal resistance, the power of the LED will have a substantial increase in the reliability of the entire assembly. For the 40mil chip, the thermal resistance can be controlled in the 1W/mk, through the use of eutectic process and other supporting, the overall thermal resistance can be controlled within 6W/mk. He said that in the country is not satisfied with the conditions of the equipment, the use of solder paste to the operation can only be said to be a temporary measure, and the same period of the supporting substrate materials also need to do a good job. The advantage of this technology is that it can improve the luminous efficiency of the chip and improve the cooling way.

However, Gong Weibin finally stressed that LED backlight with low power consumption, thin, high color saturation advantage. At present, there are a lot of LED applications in the TV needs to be improved, such as heat, color difference
