The opening ceremony of the Beijing Olympic Games is not only a grand event for sports, but also a super light show with the largest amount of LED technology ever. At the opening ceremony, LED technology was used in every festival, and countless LEDs made the Bird's Nest shine.
LED is a kind of luminescent semiconductor component and is recognized as one of the most promising high-tech products in the 21st century. While it has triggered the lighting revolution, it has also made significant contributions to promoting energy conservation, emission reduction and environmental protection. With the government's vigorous promotion and global industrial ladder transfer, China's LED will face tremendous development opportunities in the future.
Brilliant: LEDs used in the opening ceremony of the Olympic Games
Through the use of LED technology, the Beijing Olympics opening performance, successfully let the world see the dazzling and add artistic value of LED application display, also prompted the future of LED environmental protection and energy-saving lighting.
At the beginning of the opening ceremony, the 2008 people’s performances were illuminated by LED light-emitting diodes placed around the cymbal of the cymbal. The performers were able to control through the switch. The LED lighting on the raft and the background light on the scene work together to create a reciprocal effect of the opening ceremony.
The Olympic five-ring logo, which is rising in the air, is also a masterpiece of LEDs. It has shared more than 40,000 advanced diodes to form a giant five-ring of 36 meters and 12.5 meters. This LED five-ring is spectacular under the audience's camera flash and the flying actor with LED tube on it.
The center stage paper (reel) of the performance is a large screen consisting of 44,000 LED modules with a length of 147 meters and a width of 27 meters.
The large number of LEDs used in the opening ceremony has greatly promoted the future development of the industry. At present, the LED industry chain has been basically mature, and local manufacturers have formed an industrial chain that can provide epitaxial wafers, LED chips, driver chips, lamps and engineering.
Industrial start-ups are concentrated in the downstream of the LED industry chain
There are more than 600 LED companies in China, mainly in the downstream packaging and application fields. There are more than 10 companies engaged in LED upstream epitaxial wafers and midstream chips.
In 2007, China's LED market application products exceeded 30 billion yuan, and it has become the world's largest producer and exporter of LED full-color display screens, solar LEDs, landscape lighting and other applications. The emerging semiconductor lighting industry is taking shape.
China's LED market has formed certain characteristics in the field of lighting, among which outdoor lighting is the fastest growing. There are hundreds of LED street lighting companies and dozens of demonstration roads are built, but the Chinese market is in large-size LCD backlights and car headlights. Still lags behind. In China, LED display screens have been widely used, and LED automotive lights have also been widely used. Among them, the most demanding large headlights may have new breakthroughs this year. The LED backlights used in LCDs have also reached the practical application stage this year. LED street lights 2008 It is possible to invest heavily in road lighting in the year, and the concept of LED general lighting will be clearer.
The government will face huge development opportunities in promoting China's LED
The government attaches great importance to promoting LEDs. At the beginning of this year, the Ministry of Finance and the National Development and Reform Commission jointly issued the Interim Measures for the Administration of Financial Subsidy Funds for Efficient Lighting Products Promotion. This is another important measure taken by the Chinese government to increase efforts to promote efficient lighting products and promote energy conservation and emission reduction targets. The Zhejiang Provincial Government has also vigorously promoted green lighting.
At present, China's energy-saving lamp market accounts for a large share of the entire lighting market, so it still has a lot of room for development. Some institutions predict that the annual average compound growth rate of the domestic energy-saving lighting industry will reach 27% in the next five years, and With the support of national policies, development may be faster.
In the field of lighting, China is the world's largest producer and the second largest exporter of lighting appliances. The semiconductor lighting industry has a strong industrial base. Therefore, China's LED will face tremendous development opportunities in the future.
With the rise of global economic integration, the international LED lighting industry is shifting industrial ladders to China, which makes China's LED lighting industry possible to achieve leapfrog development.
