摘要
隧道照明应为驾驶员提供足够的视觉信息。隧道内亮度应与实时车流量、实时洞外亮度的变化相适应。因此,隧道运营中照明调光极为重要。DIALux软件可以实现空间环境下的灯具选择、布设以及照明模拟。介绍隧道照明的视觉特点,阐述隧道内的照明强度分配,并利用DIALux软件对隧道照明进行仿真模拟。建立隧道模型,按设计要求布置灯具并设置各种场景模式,模拟分级调光隧道内亮度情况。通过报表输出,得出隧道照明所需的一些重要信息,为最优隧道照明设计方案选择提供依据。
Tunnel lighting shall provide enough visual information for drivers. Brightness inside the tunnels shall adapt to changes of real- time traffic flow and real- time brightness outside tunnels. Therefore, lighting dimming in tunnel operation is extremely important. DIAlux software can realize selection and layout of lamps and lighting simulation in spatial environment. This paper introduces visual features of tunnel lighting, expatiates distribution of illumination intensity, and simulates tunnel lighting by means of DIALux software. The paper establishes tunnel models, arranges lamps and sets various scene modes according to the design requirements, and simulates brightness in hierarchical dimming tunnels. Based on report outputs, some important information required for tunnel lighting is obtained to provide basis for selection of the optimal tunnel lighting design scheme.
