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. The principle of integrated realization 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 setting
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 and implementation, it is easy to cause their own politics, no focus, lack of system, and can not achieve energy and efficiency.

5. Humanized lighting
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
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.
