摘 要 自然光是取之不尽用之不竭的可再生资源，它具有储量无限性，存在普遍性，使用清洁性的特点。充分利用自然光照明既节约大量传统照明用电, 又保护了环境, 已经成为现在绿色照明的一种重要能源。光导照明系统( Day lighting system ), 是继光热、光电模式后诞生的太阳能的新方式。公路隧道具有缩短公路里程、提高交通运输效率、节省用地等优越性。随着公路建设的蓬勃发展，隧道照明设施的规模和数量越来越大，隧道照明能耗及安全问题日渐突出针对目前我国中短距公路隧道存在的高耗能及不安全照明缺点，基于全自然光的智能照明根据隧道照明规范，将全自然光LED节能灯LXD3526检测光强来启动自然光照明系统和LED节能灯照明，利用单片机实现智能控制的新型照明技术应用到隧道照明系统中，满足公路隧道安全及节能照明要求，实现目的。Abstract： Natural light is inexhaustible renewable resources, it has many characteristics, such as unlimited reserves, universal existence, the use of clean. Full use of natural lighting not only save a lot of traditional electricity for lighting, but also to protect the environment, it has become an important energy source of the green lighting. Day lighting system is becoming a new way of using solar energy after light and heat, photoelectric mode. Highway tunnel can shorten the length of highways, improve the efficiency of transportation, saving land and other advantages. With the vigorous development of highway construction, growing the size and number of tunnel lighting, tunnel lighting energy consumption and security issues have become increasingly prominent. In order to solve lighting shortcomings of the high energy consumption and unsafe for short-range highway tunnel in China, this paper designed a program of highway tunnel full of natural light-based intelligent lighting system. According to the Tunnel Lighting Specification, combined with the natural light and LED energy-saving lamps, by photoelectric switch the GL30 detecting traffic flow and the photoresistor LXD3526 detecteing light intensity to start the natural lighting systems and LED energy-saving lighting, By using AT89S51 microcontroller to achieve intelligent control applied to the tunnel lighting system for the new lighting technology, to meet the requirements of road tunnel safety and energy-efficient lighting, energy saving and green lighting purpose.
