Abstract:By analyzing the surrounding environment and viewing angles of Xianxin Road Yangtze River Bridge in Nanjing, the nightscape lighting area is planned in combination with the structural characteristics of the bridge. The lighting solution of the "N"-word modeling on the upper part of the main pylon is proposed. Two nightscape lighting scheme themes of the bridge are designed, which expound the theme concept and lamps arrangement respectively. The specific lighting areas are simulated and analyzed with the simulation software (DIALux) to ensure that the luminance of each surface reaches the preset target. At last, the control requirements of the nightscape lighting control system are introduced.
