China's LED (semiconductor lighting) industry is very fortunate, and when the industry takes off, you can meet a rare Olympic opportunity. Wu Ling, secretary-general of the National Semiconductor Lighting Engineering R&D and Industry Alliance (hereinafter referred to as the Alliance), expressed the voice of the Chinese LED people. Against the backdrop of global energy shortages and rising environmental protection, the world-renowned 2008 Beijing Olympic Games and the 2010 Shanghai World Expo have all taken energy conservation and environmental protection as an important undertaking concept. The implementation of this concept is also reflected in the construction of each project. In the details. The new high-efficiency solid-state light source semiconductor LED, which is famous for its energy saving, environmental protection, long life and rich colors, is duty-bound to undertake the product mission of supporting the Green Olympics and the Science and Technology Olympics. The Olympic Games held on the land of China has brought huge historical opportunities to China's LED lighting industry. It will also become the first large-scale use of LED lighting technology in Olympic history. According to incomplete statistics, 36 games of the Beijing Olympic Games. The total value of LED products used in the venue is close to 500 million yuan, which does not include other public lighting facilities such as the Olympic Village and Olympic Park.
LED dress up for the Olympics
LED products used in the Beijing Olympics project include: landscape lighting, digital traffic information display, grooming logo, solar semiconductor lighting, outdoor full color display, emergency lighting in many Olympic applications, National Aquatics Center - Water Cube Building Landscape lighting is undoubtedly the most proud of domestic LED people. At the international LED forum held in Japan, South Korea and the United States, the speaker who made the theme report will display the picture of the water cube when describing the future development of LED. After participating in many international LED forums, Wu Ling was deeply touched by the significant impact of the Water Cube project in the international LED industry.
The water 50,000 square meters LED landscape lighting system and the 2000 square meters LED full color display system have invested a total of 51 million yuan, creating a space with water as the life and theme, showing the overall image of the bubble is crystal clear and transparent. In all LED application examples in China and the world, Water Cube is the largest LED architectural landscape lighting project. It adopts a unique transparent lighting method in the cavity, and the lamps are projected outwards in the middle and outer air pillows.
The Water Cube building represents a collection of water molecules that can represent 16 million colors. The designer of the water cube landscape lighting said that the water cube landscape lighting system has three basic colors of red, green and blue, 100,000 control points and millions of devices. For example, the opening ceremony of the Olympic Games, in conjunction with the fireworks on the square, will be changed back to the bubble wall of the Water Cube through the camera, showing the corresponding color of the real fireworks, showing a passionate and splendid fireworks. Of course, this is not the use of reflection, but the light and shadow that appear through computer control.
At present, the Water Cube has only shown the blue side to the world, which has already surprised everyone. It can also imitate the far-reaching sea, the quiet freshwater lake in the spring, and the flaming scene of water boiling in the sunset, transforming a variety of beautiful expressions. What is the energy saving and environmental protection effect of the water cube with such tension? The director of the Union Office, Zibo, has calculated an economic account for the reporter. The 50,000 square meters of landscape lighting projects all use LEDs. Compared with the traditional fluorescent lamps, the whole year is expected. Saving electricity by 745,000 kWh, saving more than 70%. Due to the wide range of semiconductor lighting applications, the energy-saving effect is becoming more and more obvious. According to the estimation of the alliance, the annual energy consumption of LED lighting products already used in China has exceeded 500 million kWh. Among them, only traffic lights (instead of incandescent lamps) can save 200 million kWh per year; LED landscape lighting (replacement of neon lights and incandescent lamps) can save more than 300 million kWh per year. For urban road public lighting, which accounts for 30% of the total lighting power consumption, such as the use of LED street light products to replace traditional light source street lamps, energy saving is more than 50%. Only a large number of demand research work is currently being carried out in China for Urban Road Alliance. Cooperated with the 2008 Engineering Construction Headquarters, Olympic venue owners and other related units to organize more than 10 matching meetings, recommending mature LED products with display and conforming to the three Olympic concepts to the owners of the Olympic venues. The products that have arrived in the Olympics have reached several hundred million yuan. It is reported that only one of the LED companies in Beijing has received more than 100 million Olympic orders. In the face of attractive market cakes, many companies are gearing up.
In the fierce competition of the Olympic Games, the industry alliance has been cooperating with the 08 project headquarters and the venue owners to guide and standardize the whole process. With the completion and delivery of the Olympic project, the construction standards, technical guidelines and specifications, and the considerations and evaluation indicators for the application of large-scale landscape lighting projects in the LED industry have gradually formed and improved in practice. Zibo told reporters that the domestic LED industry has developed rapidly, but it has always lacked relevant standards and effective testing methods. The industry standards and testing methods adopted in the process of organizing the Olympic Games benefit the entire industry. From this perspective, the application results and experience in the Olympic project will benefit every company. Especially in the industry's influential biennial National Semiconductor Lighting Engineering Innovation Grand Prix, the Olympic project is also a major subject, launching the industry-wide innovation and improvement of LED Olympic application engineering. Under the launch of the alliance, many companies in the industry are involved. In order to achieve the best operational results, the Alliance organized domestic device manufacturers to conduct field exercises on the water molecular model erected beside the Water Cube site 2 or 3 years ago. After 20 months of rain and lightning, lightning and other harsh environments were tested. , summed up a large amount of data, accumulated valuable experience for the later indoor installation. Through the participation of the competition, on the one hand, the Olympic owners and the suppliers have connected to the supply and demand information. On the other hand, the enterprises that did not participate in the Olympic supply have also mastered the experience of participating in large-scale architectural landscape lighting bidding and design. In the process of communication and communication with experts, the company has been inspired by many product designs and innovations. Although many design solutions have not been applied in the Olympics, they have obtained local architectural landscape lighting projects and important domestic buildings. Recognition of the unit.
With the advancement of the Olympic project, the performance of LED products is constantly improving. At the beginning of the Olympic project, the efficiency of domestic LED white light devices is around 30lm/W, and there is still a big gap compared with traditional lamps. We try our best to avoid shortcomings and fully exploit the advantages and features of the product. Although the quality, batch and life of different products are not uniform, the LED's important role in energy saving is undoubted. Plus LED color can be changed, controllable and color expression is very suitable for special. Landscape lighting for the environment. According to Zibo, the luminous efficiency of LED devices has improved rapidly. It has grown from less than 10lm/W in 2003 to 70-80lm/W, which is close to the level of fluorescent lamps. This development speed is other existing light source products. Unreachable. When the National Semiconductor Lighting Project was just launched, domestic high-power white-light chips could not be produced independently. However, with the development of the Ministry of Science and Technology's 15 scientific and technological projects, a new situation has emerged from scratch, and the yield of chip countries is gradually increasing. In the year, the yield of chip countries has risen to 43% to 44%.
Although the self-sufficiency rate of domestic chips is constantly improving, the domestic chip technology is still weak, and the self-sufficiency rate of power chips is still low. It takes a long period of time to achieve full localization. It is reported that most of the LED devices and lamps used in the Olympic Games are manufactured and produced by mainland companies. However, chips for some products still need to be imported from abroad. In the Olympic procurement process, we are also constantly engaged in international cooperation. Power chips are introduced from one of the top five in the world, and their supply prices are very favorable. Wu Ling told reporters that exchanges and learning with these international giants will be effective in the continuous improvement of domestic industries. The technology industry should develop with global vision and international cooperation. Only with the giants can it be improved or even Beyond.
