The Beijing Olympic Games is a grand event for sports. It can also be said that it is a grand event for LEDs. At the Olympic Games, the extensive application of LED products and its beautiful effects have made people really understand her. Although the Beijing Olympic Games has brought brilliance to the LED industry, the problems in the development of the LED industry chain cannot be ignored.
To this end, we invite industry experts and major companies to express their views on the current LED industry status, market hotspots and future strategies, aiming to jointly promote the healthy and rapid development of China's LED industry.
The application of broad and comprehensive popularity will take time
â— Due to price restrictions, it will take a long time for LED white light to be fully popularized.
â— In terms of application market expansion, it is not necessary to stick to the technical shortcomings of LED in local application fields.
â— LED application product development foundation is good, but efforts are still needed in industry standardization, product reliability, and intellectual property protection.

The bottleneck restricting the widespread use of LED products in China is price. Especially for LED products used for white lighting, although the price is decreasing, it is still difficult to compete with traditional lighting sources. Due to the price limit, it will take a long time to achieve universal popularity. At present, it can only be used in some demonstration projects. As a result, most of the high-efficiency and high-reliability LED application products manufactured in China are exported overseas, so that we are LEDs. The production of big countries is a phenomenon of using small countries.

The Beijing Olympic Games uses a large number of high-performance LEDs for various landscape lighting and display. From the aspects of overall effect, color change, dynamics, large-scale, energy saving and environmental protection, it should be said to be satisfactory. It is to promote the development of LED industry. The good opportunity has played a good role in demonstrating the better application and promotion of LED products for urban landscape lighting and the 2010 Shanghai World Expo.
It should be acknowledged that there is still a considerable gap between China's LED technology level and foreign countries. I have participated in the Water Cube Project's technical experts meeting on landscape lighting for many times before and after. The experts at the meeting have studied and discussed it many times. At that time (September 2007), it was agreed that domestic power LED products were not mature enough to ensure the quality of the entire project. Had to use foreign LED products, but the entire design, installation, commissioning, testing and other work are done by domestic related enterprises. I believe that with the continuous development of domestic LED technology and the continuous improvement of the industry level, China's LED products will surely be more widely used in the near future.
The development of LED application products should be carried out in the following three aspects: First, backlight applications, especially medium-sized display applications between 10 inches and 22 inches, mainly used in laptop computers, desktop computer monitors and monitors. At present, the technology is mature, that is, energy saving and display effect are good, and its market demand is extremely large. Second, LED applications can be used for automotive applications, including all headlights and display applications. At present, the technology is mature, and it is more energy-efficient and has great market potential. It should be promoted and applied. Thirdly, in terms of lighting, from the current point of view, we should focus on the promotion and application of interior decoration lighting and special lighting, such as street lamps, fluorescent lamps, downlights, spotlights, etc. Currently, from the perspective of LED technology, it can be suitable for these products. And more energy efficient. The market demand is large in this regard.

I personally don't think that the Olympics is a review of the current development level of the LED industry. The Olympics only provide an oversized engineering application platform. Of course, the influence of this platform is also huge. However, from the fundamental point of technical application, even on the platform of the last Olympic Games four years ago, as long as it is allowed, it can fully achieve the current performance level, at least the part currently presented to the public. Of course, this does not rule out some breakthroughs in local technology in recent years, but the impact of these local technologies on the effect is not irreplaceable.
The Olympic Games' demonstration of mature LED technology is, in a sense, a negative warning to the LED industry: one has already reached such maturity on many levels and has been infinitely close in many fields. The technology of the door of the civilian market is just a step beyond that. For us, there may be more responsibility than joy. The deep-seated problem is the problem of the standard system and the certification system, and it is more suitable for the current development, or the technical segmentation and market segmentation of the application field. This is also an important reason why China is a big country in LED production but a small country. In fact, the door of the LED civilian market has not really opened up in the world, and in terms of engineering and industrial intermediate products, foreign countries are only doing better than domestic technology and market segmentation, and the application market is also Bigger. In other words, in terms of the expansion of the application market, it is not necessary to stick to the technical shortcomings of LED in the local application field.
