1. Project Overview
The Olympic Axis Landscape Boulevard is located in the Olympic Central District at the northern end of Beijing's central axis. It is about 2.4 km from the Nanyi Road to Xindiancun Road. The 29 pillars of the landscape lamppost symbolize the Beijing 2008 Olympic Games. The central axis landscape avenue in the Olympic Park's leading position, according to functional needs to form a clear spatial sequence, lighting area of ​​about 15 × 104 m2. On the east side there is the National Stadium (Bird's Nest), a TV broadcast tower, and a sunken plaza for leisure and entertainment. On the west side are the National Aquatics Center (Water Cube), the National Stadium, the National Convention and Exhibition Center, and the China Science and Technology Museum. Lighting Positioning and Design Ideas The lighting design of Beijing Olympic Park mainly focuses on the lighting experience of people in different spaces, people's psychological and physiological feelings, and builds a beautiful and vibrant night scene image to enhance the Olympic Park landscape. The attraction and reputation.
1.1 Lighting positioning
â— Park: for the general public to visit;
â— Night lighting: comfortable, peaceful and pleasing;
â—2008 Olympic meeting area: The night scene is bright, there is a festive atmosphere, and there are conditions for celebrating the celebration.
1.2 Design Ideas 1.2.1 Highlight the nighttime landscape and create a comfortable nighttime lighting environment. 1 Night lighting uses artificial light sources, which are more flexible than natural light sources and easy to highlight key points, enabling people to better see the city's markings, contours and axes.
2 Lighting enhances the visual framework of the natural and artificial environments, creating a bright, orderly, and comfortable nightscape.
3 Lighting should be consistent with the theme of the entire park landscape, expressing visual sense of order, direction and urban personality.
4 Lighting should respond to lighting such as roads, landscape elements, buildings and advertising signs, forming a combination of points, lines and surfaces, and a clear and dynamic public lighting system that clearly reflects the integrity of the lighting system.
1.2.2 Highlight the night axis, showing the glory of the Bird's Nest, the Water Cube, the National Stadium, the Linglong Tower, and the Celebration Square. The environment that fits down the sunken plaza shows the charm of the “Dragon Pulse†in the panorama. Outstanding optical axis oriented at night, square, commercial, water, and other natural and cultural landscape lighting for the whole auxiliary lighting.
2, lighting design basis
The planning of the central axis avenue lighting sub-region is based on the overall planning design of the Beijing Architectural Design and Research Institute:
2.1 High-brightness area South 1st to Zhongyi Road, the horizontal average illumination is 33 lx.
2.2 One-way to North Second Road in the middle brightness area, the horizontal average illumination is 25 lx.
2.3 Low-brightness area North 2nd Road to Xindiancun Road, the average horizontal illumination is 10 lx.
2.4 Brightness distribution of each building â— National Stadium 8~10 cd/m2
â— National Swimming Center 8~10 cd/m2
â— National Stadium 5~8 cd/m2
â— National Convention and Exhibition Center 5~8 cd/m2
3. Lighting demand and quality
The purpose of the night lighting design is to provide the right lighting for the required space for a practical and comfortable night life environment.
There are two purposes for lighting design:
1 functional lighting (illuminating the environment, allowing people to get the surrounding information to make accurate judgments);
2 Ambient lighting (to satisfy people's sense of the landscape).
3.1 The user's needs meet the user's physiological requirements, security needs, communication needs, and the need to achieve self-worth.
3.2 Lighting quality 3.2.1 Perceived ground obstacles: Generally, the horizontal illumination on the ground is used as a measure. National Standard "Design Standard for Civil Building Lighting"
(GBJ133-90) The recommended value for the horizontal illuminance of the square in front of the station is 5-10-15 lx.
3.2.2 Visual Orientation: The lighting area should be able to meet the people who are not familiar with the surrounding environment of the area, so that when they enter the area, they can roughly perceive the entire area. Lighting should not only illuminate the ground, but also meet the space such as signs and signs. Vertical surface illumination. Can set the direction for those who are not familiar with the environment.
3.2.3 Personal identities: The area used by pedestrians, the most important role of night lighting is to enable people to identify other people who are approaching a certain distance. In order to give people the necessary sense of security, it must be possible to distinguish whether a person may be friendly, abnormal or intent to infringe in order to have sufficient time to respond appropriately.
3.2.4, Comfort and Pleasure: Lighting in public areas should be comfortable and enjoyable, as well as a three-dimensional sense of light, as well as glare, lighting effects, color temperature and color rendering, brightness ratio and other elements.
