太阳光光纤照明在公路隧道中的应用研究

摘要

The lighting system collecting sunshine has become a hptspot of research in all countries. This paper introduces development of research on sun fiber optic lighting system and analyzes feasibility of application of sun fiber optic lighting system in tunnel lighting in combination with features of sun fiber optic lighting and tunnel lighting. The paper points out that it is feasible to combine sun fiber optic lighting and tunnel lighting and reduce energy consumption of; intensified lighting at inlet/outlet sections of tunnels, and the visual problem at tunnel portals can be solved so as to realize synchronous change of brightness at tunnel portals with ambient brightness outside the portals.%采集太阳光照明系统已是各国竞相研究的热点.介绍太阳光光纤照明系统研究进展,结合太阳光光纤照明与隧道照明的特点,分析太阳光光纤照明系统应用于隧道照明的可行性.指出将太阳光光纤照明与隧道照明相结合,降低隧道出、入口段加强照明能耗是可行的,并可解决隧道洞口视觉问题,实现隧道洞口亮度与洞外环境亮度同步变化.
