中文摘要： 在国际上新的隧道照明理论和道路照明可见度研究基础上，从中间视觉、光生物效应等视觉科学新理论研究了隧道照明节能方法：利用自制的反应时间实验装置和眼动仪，研究了不同光源对高压钠灯的视觉效果相同时的等价亮度；研究了隧道照明条件下不同光源的反应时间差别，选择合适的照明光源和灯具；从光气候等理论出发，以重庆地区为例，研究了符合当地实际情况的洞外景物亮度；从模拟实验中研究最小察觉对比，通过实验分析与实测验证，获得了适宜的最小察觉对比，提出了基于等效光幕亮度理论的最小察觉对比度理念，全面应用在隧道照明设计中，提出了基于驾驶员的瞳孔变化确定隧道入口段亮度的方法，编制出隧道照明辅助设计软件"基于等效光幕亮度与察觉对比法的隧道照明计算"程序；研究了隧道不同照明段适宜的照明方式；研究了隧道照明功率密度的影响因素及基于反应时间确定道路照明功率密度的方法；基于上述研究成果，提出了更为新颖的以可见度为基础的隧道照明察觉对比设计方法。相比现有隧道照明能耗，该方法不但可以达到节能的目的，而且能够与交通安全完美结合。该研究成果可对现有隧道照明规范的修订提出新的理论和具体技术方案。

英文摘要： Based on the international newest tunnel lighting theory and the visibility research on road lighting, tunnel lighting energy saving method has been studied from the point of view of new vision science of mesopic and cirtopic. The research includes below contents: the equivalent luminance under diferent lighting sources with the identical visual effects of high-pressure sodium lamp with self-made reaction time experiment system and eye tracking systems. human's reaction time of different lighting sources under tunnel lighting condition has been studied, then appropriate lighting source and lanterns have been selected. Based on light climate theory,scenery luminance outside tunnel according to local conditions have been studied taking Chongqing for instance. Minimum perceived contrast has been studied with simulating experiments, minimum perceived contrast has been acquired through experiment,analyse and verification, then proposed the conception of minimum perceived contrast ratio based on the equivalent veiling luminance, and totally applied in the tunnel lighting design.Proposed the method of determining the access zone luminance based on the changes in the driver's pupils,and then devise the tunnel lighting aid design software-the process'Lighting Design Method based on the equivalent veiling luminance and the method of tunnel lighting perceived contrast'.Researched on proper lighting pattern in different lighting sections .Research on the factor of tunnel lighting power density and its determining method based on reacting time. Based on above studies,a novel design method of tunnel lighting perceived contrast will be proposed based on the visibility.Compared with existing method, this method will not only achieve the intention of energy saving, but also realize traffic safty. This research can provide new theoretical base and technical scheme for the revision of the existing tunnel lighting specifications.
