"The mysterious combination of light and color" is the most vivid interpretation of the night scene of the Expo. There are countless visitors to this beautiful scenery, but there are probably not many people who know the secret behind it – it is the 1.03 billion energy-saving LEDs that outline the night scene of the park. This World Expo is the first large-scale innovative application of LED lighting in the world. Therefore, it is called the centralized demonstration area and the largest show of LED technology. 80% of the night light source in the park adopts LED technology. China Pavilion, Expo Axis, Performing Arts Center... You can hardly find a place without LEDs. 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. In the “Gallery Day†event of the Shanghai Enterprise Pavilion, the Shanghai Enterprise Pavilion displayed the charm of the lights. 15,000 LED lights, 100 ç› spotlights, 100 ç› UV light combination, 75 computer moving lights, 24 ç› 7 kW searchlights, with 450 high-powered speakers, outline the visual and auditory "magic cube". The oil museum has brought the application of LED to the extreme. In the night sky, it is like an "oil cube" suspended in the air, and the surface is light blue "pipe weaving" texture criss-cross. This 4,000-square-meter electronic screen is the world's first for the large-area special-shaped PC board combination LED fine imaging. Such an LED landscape not only fully demonstrates the distinctive characteristics of the petroleum and petrochemical industry, but also has a stylish and dreamy light and shadow effect. Under the night, the oil museum is crystal clear and beautiful. The lower part of the building is a 5-meter-high glass curtain wall. It does not emit light at night. Looking at the oil gallery from a distance or in the air is like an "oil cube" suspended in the air. There are various colors of PC tube decoration around the glass curtain wall, just like a pipe leading to the ground, continuously drawing oil, providing continuous and reliable energy security for urban life and thousands of families. The “Oil Cubeâ€, which means “underground oil storage rock formationâ€, is the main source of power for a beautiful city, echoing the theme of “Oil, extending the city’s dreamâ€. LED construction is not just fashion and gorgeous, every LED light contributes to the low carbon Expo. The Expo Light Source consisting of 1.03 billion energy-saving LEDs fully reflects the concept of low-carbon Expo and Green Expo. 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. Compared with traditional lighting technology, one of the most important advantages of LEDs at present is energy saving. According to calculations, 1700 sets of LED lighting systems in the Expo Park save 60% of electricity compared to traditional lighting, and 75% of white LED lighting used in main roads and steps. In the past two years, with the support of a series of policies, the LED lighting industry has gradually developed in China. At the beginning of 2009, the pilot projects of “Ten Cities and Ten Thousand Cities†in 21 cities nationwide were launched. At the end of 2009, the state issued a notice on the development of semiconductor lighting energy-saving industries. Relevant experts said that after the World Expo, whether it is a tourist attraction, or a large-scale construction, shopping malls and hotels, the use of LEDs to replace traditional lighting fixtures will become the trend of the times. This may be the beauty we are looking for – environmental protection and energy saving make it gorgeous but not extravagant. Behind the bright lights is human thinking and exploration of the road to sustainable development.
