When the night of Shencheng comes, a beautiful "LED landscape lighting show" will be staged at the Shanghai World Expo: the east and west facades of the Expo theme pavilion will shine with the stars and the outer walls of the Expo Center will give a quiet and elegant appearance. The white light and the Expo Sunshine Valley incarnation movie screens project brilliant and dazzling patterns. The Chinese pavilion, cultural center and oil pavilion are dazzling in the shadow of the LED light source.
This "light show" is not only a visual feast, but also a feast of science and technology. As a globally recognized fourth-generation lighting technology, semiconductor lighting technology using light-emitting diodes (LEDs) has been fully demonstrated at the Shanghai World Expo Park. The total amount of LED chips used in the Shanghai World Expo Park is more than 1.003 billion. Among them, 80% of the night scene lighting in the park uses LED technology, and the Expo Park has become the world's largest LED demonstration area.
The large-scale and innovative application of semiconductor lighting technology is one of the highlights of this Shanghai World Expo. The most representative application areas include:
1. Outdoor landscape lighting
China Pavilion: Illuminating the red main structure with high color rendering LED floodlights, making the “China Red†outerwear extraordinarily stealing, using more than 23,000 LED lamps, compared to traditional exterior lighting In the floodlight mode, the LED lights of the China Pavilion can save more than 70%. At the same time, due to the long service life of 50,000 hours, the replacement cost of the bulb is greatly reduced.
Expo Cultural Center: The cultural center of the shape of the flying saucer illuminates the side walls and inner walls of the circular window through the LED linear floodlights to create the inner light transmission effect, creating a sense of the future of "space visitors", emitting a vibrant light of the times. .
Expo Center: The exterior lighting adopts yellow and blue LEDs of two color temperatures, which are arranged in a straight line of two lines, simple and well-proportioned; on several open spaces around the Expo Center, blue small ground lights are randomly embedded in the floor tiles. Going up like a random landing of the stars, adding a little liveliness to the building. The façade LED floodlighting fixture adopts a concealed structure to realize “seeing the light without seeing the lightâ€; the façade lighting adopts innovative system control and light distribution mode, and the white light color temperature and brightness of the luminaire can be continuously adjusted, in peacetime, festival, Different occasions, such as major events, can create different light and color environments, and achieve the visual effect of “normal and solemn, festive gloryâ€.
Theme pavilion: The north and south facade curtain wall aluminum panels are opened with a square hollow hole that gradually decreases in size, forming a façade texture. The lighting design uses an aluminum plate opening, and a full-color LED linear floodlight is projected below to form a space for the facade light. The sense of rhythm; the ecological green wall uses randomly arranged full-color LED decorative lamps inlaid in the swaying plants, the combination of night plants and full-color LED lights, respectively, reflects the interaction between the Expo and nature.
Expo Axis: More than 2 million LEDs and more than 90,000 sets of various types of full-color lamps and strips have been used on the 1 km long Expo Axis. At the same time, the large tension film at the top of the Expo Axis is also made of LEDs. The floodlighting lighting makes the entire Expo Axis use the dynamic characteristics of the full spectrum of LEDs to create a festive and festive atmosphere.
Expo Axis Sun Valley: At each intersection of the light steel structure, direct-view LED light-emitting points are installed. There are about 80,000 light-emitting points. The digital control system can display images and text with low resolution. Constructed the unpredictable night lights of the Sun Valley.
Urban Best Practice Area: Landscape lighting is fully LED.
Danish National Pavilion: The Danish pavilion is shaped like a giant ship made of steel. The hull is filled with holes. These holes help to ventilate and transmit light. Each hole is equipped with an LED light source to adjust the light in the hall. It is also possible to illuminate the façade at night, which is extraordinarily beautiful.
The British Pavilion: The "Seed Temple" is the highlight of the British Pavilion. During the day, the sun shines through more than 60,000 transparent acrylic rods to illuminate the interior of the "Seed Temple." At night, the LED light source contained in each acrylic rod lights up the entire "Seed Temple", making the British Pavilion dazzling on the Huangpu River.
Irish Pavilion: The exterior decoration material uses a sun panel. This polymer organic material has great advantages in light penetration and bearing. One end of the solar panel is equipped with a small-sized linear LED lamp, by controlling the combination of LED colors and Change to achieve the diversity of the “city space†of the Irish Pavilion.
The Netherlands Pavilion: “Happy Street†is directly decorated on the surface by LED point light source. The bright and flashing visual effect expresses the joyful atmosphere of the Dutch Pavilion “lighting upâ€.
French Pavilion: The use of lighting to create a sense of floating in the water, the "candle light" simulated by the lamp expresses the romantic sentiment of "sensible city".
