【 摘 要 】

The aim of this study is improving the effect of tunnel lighting intelligent control system on tunnel lighting energy-saving. Firstly, there are threshold zone, transition zone, interior zone and exit zone in a tunnel basing on the JTG-2014 in China. Then the structure and workings of tunnel lighting intelligent control system are given. The control system uses the method of "vehicle in, light brightens; vehicle out, light darkens" to save energy, and it is worthy for energy-saving. Further, in order to achieve energy-saving more on the basis of the system equipment, segmented lighting is proposed. The working-steps of segmented lighting are listed. The adjustment of LED lamps' luminance is not synchronous in a tunnel. The LED lamps of threshold zone and transition zone are adjusted to their minimum luminance earlier than interior zone and exit zone for more energy-saving. Finally, the effects of tunnel lighting intelligent control system with and without segmented lighting are compared in energy-saving. Segmented lighting has obvious effect on energy-saving, especially for longer tunnel.
