- Abstract
The main bridge of extra-long bridge over Guanting Reservoir for Beijing-Zhangjiakou High-speed Railway is a multi-span curved steel truss which is located at the section with design speed 350 km/h. A series of difficulties such as the lighting effect performance, lamps installation and light interference during the operation should be solved in the bridge landscape lighting design. In order to achieve the ideal lighting effect, the designer started from the general conception of lighting design, used linear light source to illuminate the outline of bridge, supplemented by the floodlights to illuminate other structural parts. The linear wall lamps were set on the upper chord to show the arched structure; the wide beam floodlights were set under the top lateral bracing to illuminate web member with internal transmission lighting; the wide beam floodlights were set on the pier to light the external facade. The changeable multicolor lighting was used to present several interconnected dynamic lighting themes with rich cultural connotation, which can be controlled by using intelligent lighting control system based on DMX512 protocol to achieve the area control, mode control and timing control. Research shows that the energy saving efficiency can reach more than 50% by application of LED light source and setting different scene modes. Furthermore, the installation components and fixing methods of lamps were innovatively designed to fully guarantee the reliability of lamp installation.
