Under the night, the Light and Shadow Elves danced in the Shanghai World Expo Park, transforming into a splendid and beautiful time and space. The sparkling lights, the dreamy colors, and the changing patterns of Vientiane make the Expo night fascinating, allowing night visitors to enjoy the beauty of light and shadow.
"Playing" leaping light and shadow
At 7 o'clock every night, 1.03 billion LED chips flash together, and the dazzling buildings are smart.
Light and Shadow Wizard is actually a small LED semiconductor lighting technology. At 7 o'clock every night, at the beginning of the Hua Deng, 1.03 billion LED chips in the Shanghai World Expo Park flashed together, like hundreds of millions of fireflies flying and circling under the mobilization of human wisdom, which merged into a beautiful light and shadow pattern.
23,000 LED lights put the "Oriental Crown" in a crystal clear, light and shadow, "Forbidden City Red" is extraordinarily enchanting, the Chinese Pavilion is awkward. The Expo Axis has become a dream light and shadow belt. Sunshine Valley changes colors and patterns from time to time. The large stretched film echoes with the same color light. The light steel structure crosses 80,000 LED light points in the light dance, which is both dazzling and dazzling, and complement each other. A festive atmosphere of joy and celebration. The theme hall has a star-studded face and a flash of color, which leads to people's infinite imagination. The Expo Cultural Center is like a "space flying saucer" on the banks of the Huangpu River. With the mysterious blue starlight, it is ready to sail. The large LED screen on the outer wall of the Expo Center constantly changes the waves and is elegant and chic. Crystal, beautiful, mysterious, and chic, the "One Axis and Four Pavilions" has become the most magnificent and dazzling light and shadow in the Expo.
On the elevated walkway, thousands of "lights" are at a glance. The "Moon Boat" of the Saudi Pavilion is very eye-catching. The black silhouette of the "boat side" is a string of palm trees. The gold band inlaid on the central dome of the Indian Pavilion reveals a mysterious light. The light purple curved dome of the Japanese pavilion is like a huge silkworm cocoon, as if the story of Zhu is still being played; more than 60,000 slender roots of the British pavilion must be shining at the same time, and the "Seed Temple" is covered with a bright coat. Realistic, future plants continue to release their magical potential...
Standing in the music center of the Expo Cultural Center, the Puxi Urban Best Practice Area has a panoramic view. The oil museum is like a semi-suspended "oil cube", emitting colorful light. On the LED screen of nearly 4,000 square meters, the oil production operation alternates with the urban scene, expressing the close relationship between oil and people and the city. Next to it, the violet telecommunications hall, the light blue ship hall, the green car museum... plus 33 drapes of tulip lanterns around the city square, merge into a moving light and shadow.
Show the big stage of technology
In the 5.28 square kilometer park, 80% of the night lighting uses LED, which is the world's largest LED demonstration area.
The dance of the Light and Shadow Elf is a visual enjoyment and a feast of technology.
Zhou Minhao, deputy director of Shanghai Economic and Information Committee, said that LED is a shorthand for semiconductor lighting technology, belonging to the fourth generation of lighting technology, with five major advantages: First, long working life, usually up to 60,000 to 100,000 hours, is 10 times of fluorescent lamps and 100 times of incandescent lamps; second, low energy consumption, only 6% of incandescent lamps, 30% to 50% of energy-saving lamps; third, fast response time, usually in tens of nanoseconds The fourth is easy to dim, color, can control the brightness through the change of current, different wavelength configuration change color; five is green, environmental protection, does not contain harmful substances such as mercury, no environmental pollution. Because of this, LED lighting technology and ultra-large-scale applications have become the focus of competition for energy-saving new technologies in various countries.
“1.03 billion LED chips were put into use, marking the Shanghai World Expo Park as the largest LED demonstration area in the world.†According to reports, 80% of the night scene lighting in the Expo Park uses LEDs, “One Axis and Four Pavilions†and the Urban Best Practice Area. Using LEDs, about 80% of the indoor lighting in the stadium uses LED green light sources.
An important reason why LED lighting systems can be applied on such a large scale is that China, especially Shanghai, already has a strong industrial base and technical support. As one of the national semiconductor lighting engineering industrialization bases, Shanghai has basically established a relatively complete LED industrial chain, especially in the upstream of the industrial chain, namely LED upstream extension, chip and downstream application links have certain advantages. The front end has extensions and chip companies such as Sapphire and Blu-ray, and the technology level is domestically leading; in the back-end application, Sansi LED display, Yaming landscape lighting and other products occupy a leading position in China. At the same time, many of the world's leading LED manufacturers such as Philips, GE, Daktronics, etc. will set up their headquarters and R&D centers in Shanghai. Shanghai's LED applications have expanded from indicator lights, signal lights, displays, and landscape lighting to white lighting. These have laid a solid foundation for science and technology for the Expo night sky.
Broaden application areas
Under the effect of the World Expo, China will usher in the overall development of the LED industry chain, and the application field will continue to expand.
“Shanghai World Expo is the best stage for LED lighting technology display. After the Expo, Shanghai should also become the best city platform for LED applications.†Guo Yansheng, director of Shanghai Semiconductor Lighting Engineering Technology Research Center, said that white LEDs are widely used in Shanghai World Expo Park. For the future LED lighting has accumulated experience in municipal engineering, landscape lighting and home lighting.
In order to do a good job in LED lighting application after the Expo, Shanghai has long been carefully planning and actively accumulating the focus of the LED industry development on the upstream extension of the industry chain, chips and equipment, as well as downstream high-end applications, through the introduction of digestion and absorption of innovation, Increase R&D investment, continuously improve the industrial energy level, and focus on the development of backlight products such as backlight, display, lamp, and lighting, thus driving the overall development of the LED industry chain.
Zhou Minhao said that after the World Expo, Shanghai will increase policy guidance for the LED industry, increase support and investment, accelerate the industrialization process of enterprises, and expand the scale of the industry as soon as possible; accelerate the introduction of major projects to attract well-known enterprises and talents to settle down. Shanghai, forming LED technology and talented highland; concentrating superior resources, carrying out cooperation research on production, education and research in LED materials, chips, packaging, application design technology and equipment, strengthening common technology and key technology research and development; expanding the venue and scale of LED demonstration, Promote the development of the industrial chain through demonstration applications; research and explore innovative mechanisms such as energy-saving lamp subsidies and energy efficiency management to create a good industrial development environment.
According to industry experts, the large-scale application and demonstration of LED lighting systems in 2010 Shanghai World Expo will definitely affect people's future life and production activities. It can be foreseen that after the World Expo, China will set off a wave of LED industry development.
Almost all of the outdoor led light use of large areas of lighting can be seen as led flood light. The led flood light is a fixture that specifies that the illuminance is higher than the surrounding environment. Also known as spotlight. Often it can target any direction and have a structure that is not affected by climatic conditions. Mainly used for large-scale workplace mine, building contours, stadiums, overpasses, monuments, parks and flower beds, etc. The angle of the exit light beam is wide and narrow, ranging from 0 ° to 180 °, Narrow called the searchlight.
Outdoor LED Flood Light features:
1, the use of internal and external anti-seismic structure design, effectively solve the strong vibration caused by falling off the lamp, lamp life shortened, stent fracture and other issues. This is important for outdoor led flood light.
2, Outdoor flood light with high efficiency gas discharge lamp as light source, lamp life of 10,000 hours or more, especially for large outdoor unattended lighting.
3, the use of lightweight alloy materials and high-tech spray technology, the shell will never rust, never corrosion.
4, Outdoor flood light using piping and other new technology to ensure that the shell is good, sealed and reliable, waterproof and dustproof.
5, with good electromagnetic compatibility, will not cause electromagnetic interference to the surrounding environment.
6, the overall cooling of the lamp is good, can reduce the probability of failure.
