Since its inception 150 years ago, the World Expo has become a worldwide comprehensive exhibition that brings together science and technology, industrial technology and human civilization. The theme of the 2010 Shanghai Expo is “Better City, Better Lifeâ€. This Expo will focus on the urban life of the new century. Due to the acceleration of the urbanization process in various countries, mankind is currently facing various challenges in the “urban eraâ€, such as urban development and the growing tension of the earth's resources. Therefore, one of the main goals of the Shanghai World Expo is to promote sustainable urban development concepts and to seek sustainable urban development models in developing countries.
Taking into account the theme and main objectives of the Shanghai World Expo, during the preparation and construction of the World Expo, the organizers integrated the important concept of green environmental protection, and adopted the green energy technologies such as new energy and new light sources to the maximum extent, among which solar photovoltaic power generation and LED ( LEDs are representative of semiconductor lighting. Solar photovoltaic power generation has been the focus of renewable energy technology in recent years, and it will become the main energy supply provider in the future. LED semiconductor lighting technology is a new technology developed at the end of the last century, with energy saving, environmental protection, long life and high reliability. The Shanghai World Expo fully applies these two new technologies to show the world how human beings can achieve sustainable development and how to realize the vision of a better life in the city.
For example, the Shanghai World Expo Theme Pavilion and the China Pavilion 3.12 MW solar photovoltaic power generation system have been successfully connected to the grid and began to provide Shanghai with a steady stream of green energy. For example, the Expo Axis and Underground Complex Engineering Art Lighting Landscape Project, as well as the Expo Axis 10m platform, South Square, Zhang La membrane, Sunshine Valley and green belts on both sides, use a large number of LED light sources, and The creation of various themed art lighting scenes fully reflects the innovative spirit of the Expo while saving energy. Among them, the tension film is arranged with full-color full-color temperature LED intelligent floodlight, and the middle of the film is a distributed control network composed of 3420 sets of LED intelligent floodlights. With the static white light outside the film, the whole tension film will become extremely elegant. Art canopy.
Through the Shanghai World Expo, a number of solar grid-connected power generation projects and multiple LED semiconductor lighting projects have been implemented, which not only conforms to the green design concept of the Expo, but also shows the world how humans and cities can achieve sustainable development. However, as new energy and new light source technologies are promoted in various fields, they have encountered problems such as high cost and technical needs to be improved. At present, their market acceptance is not high. We hope that after the end of the World Expo, this concept of sustainable development can be integrated into the dual areas of industrial policy formulation and people's daily life, and expand a broader development path for these technologies.
