Shanghai World Expo will open "the first year of semiconductor lighting"

LED chips appear in the Shanghai World Expo Park indoor and outdoor lighting, landscape decoration, signs, information display, etc., the entire park has become the world's most concentrated semiconductor lighting technology demonstration application area. If we say that the 1878 Paris World Expo will showcase the incandescent lamps made of tungsten wire invented by Edison, ushered in the era of incandescent lamps, the Shanghai World Expo is likely to open a "first year of semiconductor lighting."

At 7 o'clock every night, 1.03 billion LED chips were ignited together, making the Shanghai Expo Park shine. The Chinese pavilion, the Sunshine Valley with the “evening dress”, and the cultural center that seems to be ready to sail at any time, the more beautiful the night in the Expo. Experts suggest that you don’t forget the lights at night.

Each has a different "small nocturne"

From the entrance and exit of the No. 6 gate of the Expo Park to the Expo site, the first thing that catches the eye is the Chinese pavilion with the shape of the arch. The pavilion wearing the "China Red" coat adds a bit of solemnity to the daytime. Hey. The Expo Cultural Center on the banks of the Huangpu River is like a "space flying saucer" with blue stars, echoing the Chinese pavilion on the south side.

Experts suggest that elevated walkways throughout the Expo are a good place to watch the lights. Visitors can board the elevated walkway from the east side of the China Pavilion and go westward. The line of sight will hardly be blocked. They can enjoy the "Wan Guo Deng Qing". Approaching the A area, the Saudi Pavilion "moon boat" is very eye-catching in the night. The date palm on the "boat" leaves a string of black silhouettes, not far from the Japanese pavilion "Purple Silk Island" reveals a mysterious light purple light.

Li Manping, chairman of the Shanghai Semiconductor Lighting Industry Incubator, said that the Huangpu River is another good place to watch the lights. “Each venue has its own style. On the banks of the Huangpu River, visitors can bring the lights of the two parks in Pudong and Puxi together.”

The brighter it does not mean the better

How to taste the gorgeous costumes of the venue? Li Manping said that the lighting of the stadium landscape lights is not as bright as possible, but combined with architectural style. For example, the Chinese pavilion should reflect its red color, the theme pavilion should reflect its elegance, and the cultural center combines its flying saucer shape to reflect the feeling of flying outside. “The Pudong National Pavilion is rich in light and color, and it is more tasteful from the perspective of art and culture. The indoor and outdoor lighting in the Puxi City Case Area is experimental, and it is certainly a lot from a professional perspective.”

In order to avoid the light pollution caused by the landscape lights in the park, the lighting designers also considered the regional distribution and the light and dark layout of the landscape lights. “Because the over-brightness or flashing frequency is too high, it is easy to affect the vehicles on the Lupu Bridge. Therefore, the flashing frequency, angle and brightness of the stadium lighting near it are specially designed.”

Reduce energy consumption by 60%

According to statistics, 80% of the night scene lighting sources in the Expo Park have adopted LED technology, which has reduced energy consumption by about 60% to 70%. Li Manping said that Shanghai World Expo is the world's first large-scale LED integration application case. The world demonstrates the possibilities of LED lighting for future applications. “'Shanghai·Ecological Home' is the only venue in the park where all lighting uses LED lighting technology, and is also a case of future energy-efficient buildings. The Expo provides a lot of materials and data for LED light color research. These are expected to promote LED lighting enters the field of home lighting." (Editor: Green Light Xiang)
