LED show: Shanghai, World Expo with the number of LED chips

2010 Shanghai World Expo has become the largest LED show the history of the World Expo, has become the world's largest demonstration zone LED. This large-scale demonstration also shows that China has become the largest LED output and the largest market in the country. So, in 2010 in Shanghai, World Expo, in the end how many LED chips used? Everyone's response is how Aladdin lighting network reporter by visiting experts, industry, to understand the latest developments. It is reported that the Expo site uses 1 billion 50 million LED chips; Expo venues indoor lighting light source of about 80% using the LED green light source, compared to ordinary incandescent power up to about 90%.

1 billion 50 million LED chips to create the perfect Expo

Looking back at history, every leap in human lighting technology has left footprints in World Expo's history. 1873 Vienna, World Expo, the invention of the electric motor ushered in the era of mankind. 1878 Paris, World Expo, Edison invented incandescent bulbs are installed on the Eiffel Tower, the entire park will be crystal clear. 1939, New York and Losangeles, World Expo, shows the first practical fluorescent lamp. Some people said, Shanghai World Expo may become the first year of solid state lighting".

Bright night, is one of the highlights of Shanghai, World Expo, which is mainly due to the application of large-scale LED (light-emitting diode) lighting new technology. The night is still decorated LED Expo is magnificent. And this is due to a small LED (light-emitting diode)". Not only "one axis four Pavilions" and the best practices in the city of PHILPS landscape lamps.

Although the bright lights of Expo Park, but the actual power consumption is not too large, which is largely thanks to the energy saving features of LED technology. As a new type of solid-state light source, LED has the characteristics of small size, low power consumption, long life, fast response and high reliability. It has been recognized as an important energy saving and environmental protection material. Shanghai semiconductor lighting engineering technology research center director Guo Yansheng introduction, the Expo Park such a large scale LED lighting applications, comprehensive energy efficiency can reach more than 70%. LED once again to exert its fist, with its huge visual impact once again created a shocking scene of the world, creating a perfect Shanghai World Expo.

LED large screen help Expo event

Expo LED display to illuminate the future of the city, World Expo is the highlight of the LED display, from the opening ceremony to the Saudi Arabia Pavilion fully experience the fun of the big screen LED bring us!

The opening of the Huangpu River side of the huge LED big screen memorable. This is 300 meters long, 30 meters high, a total area of over 9000 square meters of the display, the pixel size of 15 cm, is currently the world's largest outdoor LED display, it Xuandong patterns and fireworks together, to the people left a good memory. In addition, the Expo Park square, the museum wall can also be seen everywhere large and small LED display. Compared to the traditional traditional display and posting notices, LED display brings more information and convenience.

Taiwan museum lighting water table for the lantern also used LED display technology, created a wonderful scene sky lanterns slowly off. "Peace and prosperity" and "peace and love"...... An electronic blessing lamp blessing to the hearts of the people of the world.

Expo Park, one of the top 91 Saudi Arabia's curator of the meter, the width of 47 meters of the moon boat shaped building, large LED screen on the hull of the children playing around the world smile. German Pavilion climax program source of power, the big ball surface, but also filled with 400 thousand LED light-emitting diodes used to display the changing pattern. Oil Museum, general Museum, meteorological hall, etc. are also equipped with a unique LED screen, and show the theme of the museum complement each other.

In the city best practice area in Puxi, and a LED light brick paved road, when night comes, the LED system can change over time showed different patterns and colors on the ground, to provide information for visitors.

Peace of mind is committed to the development of the industry

Behind the prosperity and development, some experts have suggested that "World Expo is not to narcissism, self satisfaction, if with this mentality to do, go to World Expo, the last harvest is very small, the real harvest should be a universal enlightenment, enlightenment of civilization. "

The Olympic Games is a grand event of human being, and World Expo is the exhibition of the comprehensive ability of human beings. From the Olympic Games to the World Expo is a good start, China's real integration into the world, in the face of the world to fully demonstrate our cultural charm.

On the scale, China is already a big country in the LED industry, but in the field of technology, China still has a gap from the international advanced. It is reported that most of the Expo LED lighting to achieve localization, but the majority of LED chips imported chips. In other words, behind the fiery investment in the LED industry, is an embarrassment to have to face the fact that the domestic LED companies in the epitaxial film, chips and other key aspects of the lack of the right to speak. Data from the China Lighting Association show that in the LED industry chain, epitaxial wafers and chips accounted for 70% of the profits, while the LED packaging and application only accounted for about 30% of the profits. Epitaxial wafer production is still completely controlled in the hands of foreign companies, domestic enterprises have not been able to achieve epitaxial film production. Chip, domestic enterprises are mainly concentrated in the field of low power, in the field of high-power high-end technology, production, quality and other issues.
