公路隧道照明控制技术综述

Overview of Lighting Control Techniques in Expressway Tunnels

为消除"黑洞效应"和"白洞效应",需对公路隧道照明进行有效控制,以使隧道内电光源照明亮度与隧道外自然光亮度之间尽可能建立一种相对稳定、较为缓和的照明亮度递减适应曲线,满足公路隧道运营安全的需要,最大限度地节约电能。从控制方式、控制方法、控制参数和控制系统等4方面全面阐述公路隧道照明控制技术的发展,并指出目前公路隧道照明控制技术应用存在的主要问题,展望公路隧道照明控制技术的发展趋势。

In order to eliminate the ＂Black-hole effect＂ and ＂white-hole effect＂, the lighting in expressway tunnels shall be effectively controlled so as to establish a relatively stable and gradual adaptive curve to degression of illuminating brightness as much as possible between the brightness of optoelectric source in tnnnels and the brightness of natural light outside the tunnels, satisfy the needs of safe operation of expressway tunnels, and maximize saving of electric energy. The paper expatiates the development of light- ing control techniques in expressway tunnels from control modes, control methods, control parameters and control systems in an all-round way, points out the major problems existing in the application of lighting control techniques in expressway tunnels at present, and puts forward the prospect for development trend of lighting control techniques in expressway tunnels.
