高速公路隧道照明系统节能技术的发展

Development of Energy-saving Technology of Highway Tunnel Lighting System

隧道照明系统不仅影响隧道通行安全,同时又是能否降低公路隧道建设成本及运营成本的关键所在。在保证隧道通行安全的前提下,有效降低照明功耗是非常必要的。本文对隧道照明节能灯具、基于参数优化的隧道照明节能研究,以及基于智能控制的隧道照明节能研究进行了总结和分析,提出一种更加节能的方案,即在隧道照明满足安全通行的前提下,隧道各段LED灯的布灯参数以节能为目的进行优化,对布灯参数优化后的照明系统,进行无极调光控制,最后,采用CAN总线对各段照明灯具的功率进行控制和管理,实现隧道照明系统的最大化节能。

The tunnel lighting system not only affects the safety of tunnel traffic, but also is the key to reducing the construction and operation cost of highway tunnel. Under the premise of ensuring the safety of the tunnel traffic, it is necessary to effectively reduce the power consumption of lighting system. Energy-saving studies based on energy-saving tunnel lighting lamps, parameters optimization of tunnel lighting system, and intelligent control were summarized and analyzed. A more energy-saving and efficient scheme was proposed, i.e. optimizing the installation parameters of LED luminaires of all sections of tunnel with the purpose of saving energy, under the condition of tunnel lighting meeting the traffic requirements, then, stepless dimming control was carried out through the installation-parameter-optimized lighting system. Finally, CAN bus was used to control and manage the power of every LED luminaire, so as to maximize the energy saving of the tunnel lighting system.
