Editor's note: The night view of the Expo site will undoubtedly be the most beautiful and most attractive place in Shanghai during the 2010 World Expo. The entire night lighting system not only provides a guarantee for the continuation of daytime activities, but also an endorsement of the image of Shanghai during the World Expo. In the exhibition space and all the buildings and traffic spaces on the Expo site, lighting is one of the elements to coordinate the overall landscape, which plays a very important role in the overall design of the design. Scientific planning and design of the light environment of the Expo site is a scientific and orderly guarantee for the construction of the night lighting of the Expo; it is also an important technical means to achieve a safe and efficient World Expo and the promotion of Shanghai's urban image. The comprehensive establishment of an energy-efficient night scene system for the Expo site is an outstanding contribution to China's green lighting project and the global sustainable development process. At present, the night lighting of the Shanghai World Expo has not yet reached a mature supporting approach that can be directly used for planning and design. According to the current design and construction cycle, the feasibility of these technical applications must be studied as soon as possible, and the related technologies that can be used for the night lighting of the Expo will be integrated to lay the foundation for the next stage of night vision planning and design. 　　 I. Master Plan of Landscape Light Environment of Shanghai World Expo Park 1) Scientific Positioning of Night Scene Lighting in Shanghai World Expo Park The crisis of urban electricity use in Shanghai has forced us to rethink and scientifically position the nightscape lighting of the Expo site. We cannot ignore the reality of the country and do things that harm the interests of the people and future generations. The night vision lighting of the Aichi Expo in Japan attaches great importance to the issue of energy conservation and the achievements it presents. It is also the content we draw from and need to study. The economically developed countries like Japan are still doing their best, and we should give a scientific positioning to the nightscape lighting of the Shanghai World Expo Park, making the 2010 World Expo a model of energy efficiency. 2 ) Integration principle of landscape art lighting in the park The night landscape construction of the Expo Park will focus on a large number of advanced science and technology at home and abroad, and will be displayed through the comprehensive application of city and landscape, light and lighting, which involves the intersection of multiple disciplines and the cooperation of different industries. At the macro level, we will grasp the global strategic development concept of ecology, energy conservation, green lighting and sustainable development, and translate it into technical points of various planning and design, so as to propose the night illumination of the Expo Park with technology as the guide and artistic creativity. The operational principle of construction. 3 ) Constructing an efficient and energy-saving light environment system in the Expo Park The light environment system of the Expo Park aims to promote energy conservation, environmental protection and lighting quality to adapt to and serve the social progress and modernization of the Shanghai and Shanghai World Expos. The purpose is to further promote the development of efficient lighting in urban landscapes, improve the product quality of production enterprises, guide and standardize market order, and expand the market share of high-quality lighting electrical products. Through the establishment and promotion of the system, we will raise awareness of energy saving and awareness of high-efficiency lighting products, increase market consumption of products, and gradually establish a healthy and sustainable high-efficiency lighting product market and service system to promote lighting and energy saving. China's energy conservation and environmental protection cause is booming. 4 ) Regional lighting settings The total area of ​​the Red Line of the Expo site is about 5.28 square kilometers, including 1.35 square kilometers in Puxi and 3.93 square kilometers in Pudong. In such a large-scale area, how to carry out appropriate brightness distribution, highlight the nighttime landscape focus and the iconic landscape group, avoid the overall brightness is too high and lose balance or increase power consumption, from the scientific lighting, reflecting the light culture level planning and Design research is very necessary. According to the spatial landscape framework of the “first line, two axes and three rings†of the World Expo, the illuminance level of each area is determined in detail, which is also the standard and basis for formulating the light level from the technical point of view. Otherwise, there is no scientific night lighting technical standard in the Expo Park. Under the series of construction implementations to operate? This is very easy to cause their own politics, no focus, lack of system, and can not achieve energy-saving efficiency. 5 ) Humanized lighting requirements During the World Expo, a large number of people from home and abroad will gather in the Expo Park. It is conceivable that the Expo Park at night will still hold various events and a large number of visitors will be stranded. Considering human visual effects and limiting glare is the premise of realizing the "people-oriented" design thinking. For visual perception and visual psychology, light color hobbies, how to effectively limit glare in the park, how to form a visually comfortable light environment of the Expo Park is the basic premise and basis for realizing the high efficiency and energy saving of the night scene system. 6 ) Green lighting requirements To carry out research on green lighting and light pollution control, the purpose of which is to correct the unilateral pursuit of high brightness, multi-color and large-scale in the current urban lighting work; to promote lighting and energy saving, to achieve the goal of comprehensive urban power saving in Shanghai during the 2010 World Expo. . By promoting urban green lighting, reducing greenhouse gas emissions; formulating standards and standards for lighting energy conservation in the Expo site, and promoting scientific, healthy and sustainable development of urban lighting in Shanghai and even the whole country. Today, facing the global energy crisis, new energy development has become a major issue for all mankind. China's energy challenges and the destruction of the ecological environment caused by the transition consumption, there is an urgent need to vigorously promote the use of new environmentally friendly green lighting products. For the application of a new generation of energy-saving light source LEDs, the use of solar energy and solar spectrum is also in line with the “World-Pacific planning idea of ​​harmony between man and nature and zero energy consumptionâ€. During the Shanghai World Expo, not only must we fully demonstrate the achievements of high-efficiency and energy-saving artificial lighting technology, but also highlight the progress and practical experience of human beings in the 21st century. The Expo Park should fully implement green lighting, and adopt scientific lighting design to adopt high-efficiency, energy-saving, environmentally friendly, safe and stable lighting products, and become a demonstration of urban scientific lighting. This will help improve the urban living environment and improve people's quality of life, thus creating a safe, comfortable, economic and beneficial environment and fully embodying the lighting of the city's modern civilization. 7 ) Environmental color and artificial lighting color design of the Expo site The environmental color of the Expo site is directly related to the color of artificial lighting. The accurate reproduction of the full-spectrum color appearance is the key to creating a true color environment in the park; while the light-color art expression creates a colorful night landscape that is distinct from the daytime landscape and fascinating. The diversified application of color rendering and color temperature will enhance the identifiability of the functional zones of the Expo site at night. Second, support the frontier lighting technology of the Shanghai World Expo The Expo will be an important platform for demonstrating the level of national science and technology and a concentrated display of the application of scientific and technological achievements. Through the research on lighting ecological technology and the application of new lighting technology, it will give the most powerful technical support for the construction of the night landscape of the Expo. With the rapid development of ecological technology and information technology, energy and new materials technology, remote monitoring technology, multimedia technology, communication technology and network technology are becoming more and more mature, making full use of the remote transmission of lighting system signal acquisition, storage, processing and lighting control. To meet the needs of digital lighting construction in the Expo site, to achieve efficient, energy-saving, ecological green scientific lighting. 1) Lighting ecological technology 2) Lighting technology application The comprehensive utilization of modern lighting technology is an important part of the night lighting of the Expo Park. It not only provides functional lighting, but also plays the role of landscape lighting in the park, which is crucial to the overall image of the park. The Expo should have typical characteristics of the lighting image design, including lighting design, light source selection, material and protection level and artistic design. Performance lighting will be the most active visual element during the Expo. The design and control of dynamic lighting is a topic worthy of further study. Lighting design is a comprehensive art, and the method of applying sound and light heat and dynamics to the Expo is of value. The experience of previous World Expos tells us how to integrate the application and performance of landscape, art and lighting technology is a test of the comprehensive strength of the host country, and also a display of the city's charm and technology level from the visual effect. In the same period of construction of the stadium, the issues of frontier lighting technology, park light environment, modern lighting technology comprehensive utilization, energy saving means and light pollution control are all needed to be solved in the previous research, so as to be in the subsequent links. Gradually implement it. 
Third, the comprehensive use of modern lighting technology
