基于瞳孔变化的隧道内饰材料辅助照明研究

在公路隧道运营中,照明系统是与行车安全、舒适度关系最为密切也是最为直接的部分,照明系统也是隧道运营中能耗最大的部分。隧道照明系统是为隧道内驾驶人员提供良好的照明环境以满足其视觉需求。目前国内隧道照明研究方向多集中于隧道光源本身,而对于隧道侧壁内饰材料反射光的辅助照明作用却鲜有研究。笔者通过对国内外隧道照明技术和方法的大量调研,利用眼动仪、光谱仪等仪器开展了基于驾驶员瞳孔变化的隧道内饰材料辅助照明的室内模型模拟试验和实体隧道试验的隧道照明试验,对隧道内饰材料在隧道照明中的辅助作用及规律进行了探讨,旨在为内饰材料在隧道照明系统中辅助性运营的进一步推广应用提供一定的参考价值。

Study on the Tunnel Lighting of Tunnel Interior Material Based on the Pupil Changes

In the tunnel operation,the tunnel lighting system is the key component about the road safety and comfort,it is also the biggest energy consumption.The tunnel lighting system must meet drivers' visual demands.At present,domestic research on the tunnel lighting is most concentrated in the light source itself,while the reflected light from tunnel side wall's auxiliary function is ignored.Through massive investigation and research on tunnel lighting technology and method at home and abroad,the eye tracker and spectrometer etc was used,a series of models and real vehicle experiments based on drivers pupil reaction was carried out.At last we discussed and summed up tunnel interior material lighting booster action mechanism,which provided design ideas and reference for tunnel interior material auxiliary popularization and application in tunnel lighting system.
