The third prize of the evaluation result of the Zhongzhao Lighting Award Lighting Engineering Design Award (outdoor/bridge, road)
Project Name: Subway Xihongmen Viaduct Night Scene Lighting
Reporting unit: Beijing Haoersai Lighting Technology Co., Ltd.
Project Description
Beijing Metro Line 4 is one of the Beijing subway lines. The total length of the line is 28 kilometers. There are 24 stations in total, starting from the public welfare Xiqiao Station in Fengtai District, ending at Anheqiao North Station in Haidian District, connecting Beijing South. Stations, Xidan, Zoo, Zhongguancun and other important transportation hubs and commercial districts are one of the main aortics of Beijing's north-south traffic. The entire line was officially opened to traffic on September 28, 2009. On December 30, 2010, the Beijing Subway Daxing Line, which was opened on the same day, will be operated. The No. 4 train can be directly operated to the Tiangongyuan Station of the Daxing Line Terminal.
The design scope of this project starts from the middle section of the viaduct of Xingong Station, after passing through Xihongmen Station, until the subway enters the ground, the total length is 2380 meters. The initial section is also the boundary point between Fengtai and Daxing. This is also the Daxing Line subway entering Daxing. The first scenery of the district. When the night comes, when the speeding train passes, the LED full-color contour lights change synchronously with the train. The LED floodlights on the column show the steel aesthetic of the light rail structure. All the colorful changes illustrate the rapid development of Daxing District construction. Daxing people are struggling to get up.
Innovations in lighting design concepts, methods, etc.:
The lighting design concept of this project is: the train in the speed, the development of the big. In the lighting treatment, the LED full-color contour light is used to outline the two sides of the viaduct to highlight the overall sense of the bridge structure. At the same time, with the dynamic control mode of the light, it blends with the spirit of the train to fully express the design theme. The sides of the bridge are illuminated by T5 linear floodlights, and the color temperature is 3000K, which enhances the volume of the viaduct; the LEDs are staggered by the LED floodlights to highlight the strength and beauty of the bridge structure.
In view of the fact that the project is a subway bridge project, it is also a rare long-distance bridge lighting project in Beijing. It has made sufficient argumentation and research on the impact of the installation method of the lamp on the bridge structure and the stability of the later operation. The meeting decided to pass the resolution.
Energy saving measures in lighting design:
The light source used in this project is LED products and T5 fluorescent lamps, which are currently actively promoted in China; LED lamp chips adopt US CREE, T5 fluorescent lamps adopt OSRAM products; at the same time, T5 line type spotlight ballasts are selected. The electronic ballast is used, and its power factor can reach above 0.95. The control method adopts hierarchical control, and different opening control modes such as weekdays and holidays are set according to the usage conditions, which also plays a role in energy saving effect in the later operation. Decisive role.
