LED lighting and lighting to create a night scene

The hustle and bustle of the night scene is one of the highlights of the Shanghai World Expo, and this is mainly due to the application of new technologies for large-scale LED (light-emitting diode) lighting. According to estimates, the LED chip usage of the entire park is over 1 billion, and more than 80% of the nightscape lighting sources in the park use LED technology. The low-carbon characteristics of LED coincide with the concept of Shanghai World Expo, which will inject new vitality into the future urban development.

The permanent venue of the World Expo “One Axis and Four Pavilions” is the most concentrated place for LED applications. The unpredictable night view of the Expo Valley Sunshine Valley is one of the attractions of the Expo Park. There are more than 80,000 LEDs on the top. The Chinese red, which is distinctive in the China Pavilion, is also reflected by the LED white light. The theme pavilion, the Expo Center, and the Cultural Center also have their own colors. At the opening ceremony of the Expo, the world's largest outdoor LED display with a length of 300 meters and a height of 30 meters also created an unforgettable visual feast together with the rotating fireworks.

In addition to the “One Axis and Four Pavilions”, the Plaza Landscape Lighting, the Riverside Landscape Belt, the Logo and Intelligent Guidance System, and various national pavilions in the Expo Park have mostly adopted new LED lighting technologies.

LED display digital controllable lighting idea

The biggest highlight of the Taiwan Pavilion - the blessing sky lantern on the water table is the application of LED display technology, which transforms the wonderful scene of the sky lanterns. "Guotai Min'an", "Love and Peace"... An e-blessing light sends the blessings to the hearts of the people of the world.

One of the most popular places in the Expo, the Saudi Pavilion is 91 meters long and 47 meters wide. It is a "moon boat" building. The large circular LED screen on the ship plays the smiles of children around the world. The large ball surface of the German Pavilion's climax program "Power Source" is also covered with 400,000 LED light-emitting diodes to display the changing pattern. The oil museum, general museum, and meteorological museum are also equipped with distinctive LED screens, which complement the theme displayed in the museum.

In the Urban Best Practices area of ​​Puxi, there is also a pavement with LED lighting and floor tiles. When the night falls, the LED system can display different colors and patterns on the ground as time goes by, providing information for tourists. .

LED market energy saving over 70% of the application market

Although the Expo Garden is awkward, the actual electricity consumption is not too large, thanks in large part 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 environmentally-friendly lighting material in the world. Guo Yansheng, director of the Shanghai Semiconductor Lighting Engineering Technology Research Center, said that the comprehensive energy-saving efficiency of such a large-scale LED lighting application in the Expo Park can reach more than 70%.

Since 2005, Shanghai has started to develop LED lighting for the World Expo, and has accumulated a large number of technical foundations, such as semiconductor lighting and architectural nightscape art design technology, semiconductor technology and intelligent control, networked system integration technology, domestic high-power white light. LED device scale application technology.

China is now the world's largest LED application market, and the semiconductor LED lighting is included in the medium and long-term science and technology development plan. There are 7 national semiconductor lighting industrialization bases in the country, and Shanghai is one of them. In addition to display and lighting, LED technology has also begun to be applied in the fields of optical medical, seedling cultivation, and household goods.
