LED: the rational call behind the hot

LED industry: behind the big call rational

With the continuous upgrading and improvement of LED lighting technology, LED has been widely used in the display, backlight, building landscape lighting, interior decoration, such as the deterioration of automotive lights. Especially with the national energy conservation and emission reduction policy formulation and promotion, from central to local governments, from lighting designers to terminal owners, in the field of engineering lighting set off a "LED hot".

Data show that in 2008, the global LED market application increased from $12 billion 500 million in 2004 to $50 billion, the world is waging a battle to seize the LED market share, especially in China's huge market has yet to be developed, it is the main battlefield of the domestic and foreign lighting giant "".

According to authoritative forecasts, under the strong impetus of the 2008 Beijing Olympic Games, China's LED lighting market size from 2007's rapid growth of $4 billion 850 million to $9 billion 810 million in 2010, LED will gradually enter the mainstream lighting system. At present, China's lighting industry output value reached about 80000000000 yuan.

LED lighting great prospects, led to the domestic LED lighting investment boom, many companies have launched LED lighting production line, put a lot of money, and actively seize market share.

However, despite the prospect of high fever induced by domestic enterprises wave after wave of LED gold frenzy, can not be ignored is that behind the hot, LED industry is also hidden a lot of hidden dangers.

Many industry insiders believe that, LED lighting industry is a capital intensive industries, investment intensity, high technical difficulty. Long industrial chain, technical difficulties, high investment, long cycle, these are the gold LED domestic enterprises need to face up to the problem. While the domestic LED industry are facing shortages of basic research, development, and the current world is in the shadow of the financial crisis, eager to processing and sales of LED products in this kind of situation, it will inevitably lead to vicious competition caused by repeated investment. More and more experts began to call for reason: Although the development potential of LED lighting is huge, but in the current level of technology, the cost has not been significantly reduced, investors should choose a good time and investment.

One side is fanatical enterprise chase, while experts criticize cold.

The future development direction of the application of LED in the market? What kind of LED lighting products? Application engineering of LED products purchasing needs and opportunities and where? The widely used LED product quality and technical transformation of space where? LED applications industry norms and standards of how to develop? This is every LED lighting manufacturing enterprises, the focus of attention of designers. Based on this, Aladdin lighting network organized by the 2009LED application product status and Trend Analysis Seminar, but also has a profound practical significance.

Seminar guests: keynote speech colorful

At -18 in the domestic LED industry gathered in Shenzhen this seminar on the afternoon of April 25th 13, a total of two hundred people. According to the meeting the theme of subdivision in two branch field began at the same time.

The former Southeast University professor of electronic engineering, Jiangsu Institute of lighting, honorary chairman of the State Council special allowance winner Yang Zhengming, a professor at the Fudan University (Bo Dao), deputy director of the Shanghai Institute of lighting and lighting Chinese association deputy secretary general, members of the international visual working committee Chen Da Chinese "explore" white LED applications launched a deep research on speech; Tsinghua University Shenzhen Graduate School of Physical Electronics and laser devices professional, associate professor, deputy director of Tsinghua University Shenzhen Graduate Institute of semiconductor lighting laboratory Qian Keyuan, the international standard OLED project leader, LED backlight, light radiation safety international standard expert group members, Zhejiang University of optoelectronic information engineering department associate professor Mou Tongsheng as a guest speaker on LED development prospects and opportunities, China international standards "conducted a comprehensive analysis.

Two venue, the same wonderful, for the industry to contribute a high, refined, deep professional and technical seminars.

Yang Zhengming: do LED street to seek truth from facts

Mr. Yang Zhengming bluntly directed the 6 big reasons cannot resolve LED road lighting: 1.LED performance indicators is difficult to meet the requirements; the optical system of 2.LED is not mature; supporting the control circuit reliability of 3.LED is too low; the cooling system of 4.LED is too expensive, the efficiency is not high; 5 of the entire LED lighting system cost is too high 6, can not be extended; there is no uniform standard, the products are not the same without interchangeability, difficult maintenance and high cost.

He then describes a realistic evaluation for white LED3: 1.LED is a promising light source; 2 monochrome LED and small power white LED in the display lighting and local lighting decorative lighting, small power has shown its superiority, and will play a strong role, but many aspects remain to be perfect 3; on the high power white LED exaggerated publicity carefully.

He called for: experts, professors, suspend your own costs nothing to focus on the light efficiency of road lighting system and improve the reliability, reduce the cost, do a bit of real LED is the research and development work.

Chen Dahua: rational call for the healthy development of LED

Mr Chen Dahua thinks, want to call, rational in white LED application must first, rational learning and understanding of the LED luminous principle, in the full advantages and disadvantages, based on the price and use requirements, establish regulations and standards gradually extended. Secondly, the development of China's LED industry with high-tech chip technology and independent intellectual property rights as the core. Finally, a comprehensive focus on the dynamics of SSL, especially the rise of OLED.

Talking about the application of LED as street lights and tunnel lights, Professor Chen mentioned: first, the advantages of LED
