Night illumination design of No.1 Tianqiao in Zhongguancun, Haidian District
The third prize of the evaluation result of the Zhongzhao Lighting Award Lighting Engineering Design Award (outdoor/bridge, road)
Project Name: Night Lighting Design for Tianguancun No.1 Zhongguancun, Haidian District
Reporting unit: Beijing Municipal Engineering Design and Research Institute
Beijing Yihe Yongzhen Environmental Art Design Co., Ltd.
Project Description
　 The project is located at the intersection of Zhongguancun Street and Sihuan in Haidian District, Beijing, and is located in the core area of ​​Zhongguancun.
The bridge as a whole is a cross-shaped shaped bridge. The maximum span of the overpass is about 48 meters, the minimum is about 35 meters, the total length is 327 meters; the ladder is 4.5 meters for each step; the escalator is 6 meters high; the vertical lifting platform for disabled people is 6 meters. The flyover is also the most significant and important transportation node in the region.
“Zhongguancun†is China’s “Silicon Valley†and one of the most representative business cards in Beijing, and its status and reputation in the field of high-tech in China is unique. The design team and the bridge architects of the design institute conducted in-depth discussions and research. Finally, the design method of integrating the lighting equipment with the bridge structure and integrating design was determined. On the basis of fully expressing the effect of the bridge building landscape, the technical means of lighting at night, so that the bridge can meet the lighting function, and can become a carrier of the modern, humanistic and fashionable overall temperament of the Zhongguancun area, showing a distinct Its iconic and unique character has become a new landmark in the region.
The external illumination of the bridge mainly adopts the warm yellow color as the main tone, and the white light touches the illumination method. While fully embodying the structural beauty of the bridge building itself, the bridge given to the night is both brilliant and elegant.
In addition, in the space of the near-person scale on the bridge, the interior lighting method is used for reference, and the bridge deck is illuminated by the soft diffuse reflection light of the ceiling to create a relaxed and pleasant atmosphere. For the pillars and railings, while maintaining uniformity with the outside of the bridge body, it pays more attention to the comfort of people passing through and reflects the care of humanities.
In order to control the effect, a large number of custom lamps are used in the design, and the light source is a high-efficiency, low-energy LED. These customized lamps not only create the effect of integrating with the environment of Zhongguancun, but also meet the visual needs of different groups of people in various small environments, and fully meet the design principle of “people-orientedâ€.
Innovations in lighting design concepts, methods, etc.:
1) Design concept:
Through the organic combination of modern design techniques and lighting technology applications, the building and the luminaires are blended. On the basis of ensuring the daytime landscape effect of the bridge building, the building was carefully engraved with light at night, making it a landmark building in the Zhongguancun area under the new lighting technology, and finally achieving the perfect unity of light and environment.
2) Integration of non-standard special lamps and architectural forms
In order to ensure that the deeper humanistic connotation of the project can be fully reflected in the night light, the design team participated in the design of the bridge shape from the beginning, and carried out a lot of research and experimentation, fully making each lamp, every detail , all meet the needs of the environment. Moreover, at the time of design and installation, the structure and the luminaire were uniformly arranged, and finally the thermal integration of the luminaire and the building structure was completely achieved.
3) Beautiful and colorful cadenza
Taking into account the characteristics of the traffic building, the color of the bridge is divided into two spaces outside the bridge and inside the bridge.
The space outside the bridge is set to a yellow color with a color temperature of 3000K, which makes it have a good penetration with the elements of the surrounding light environment, forming a striking but fitting landscape lighting effect.
The color of the space inside the bridge forms a contrasting color with the color outside the bridge. The space height forms a color gradient from cold to warm from top to bottom. The color matching of various types of custom lamps is rich, and it is presented according to the skeleton level of the building structure, and the environment is sufficient. Fusion.
