摘要
国内外对公路隧道照明的智能控制技术进行了较为广泛的研究,但目前智能控制采用的光环境参数仍为传统设计标准。隧道照明最重要的问题是解决视觉适应问题,而各国设计标准及设计方法均仅考虑亮度适应,没有考虑色温突变对视觉适应和驾驶员生理变化的影响。同时,入口段亮度(Lth)和洞外亮度(Lth(s))直接影响驾驶员进入隧道的视觉适应过程,但目前根据洞外亮度确定入口段亮度时仅考虑了车流量和设计车速2个因素,实际上,洞外亮度和车流量是不断变化的,从洞外天然光色温到洞内光源色温的突变对驾驶员的适应过程有重要影响。因此,按传统标准进行照明参数设计的智能控制系统不符合人眼视觉特性,会出现"过度照明"或"无效照明"现象。同时,色温的变化也会造成驾驶员一些生理反应的变化。结合隧道智慧照明的发展历程和色温突变对驾驶员影响的相关研究,探讨基于色温修正的隧道智慧照明研究重点和发展方向。
The intelligent control technology of highway tunnel lighting has been extensively studied both at home and abroad.However, the light environment parameters adopted in intelligent control are still in accordance with the traditional design standards. The problem of tunnel lighting is the most important to solve visual adaptation problems throughout the design criteria and design methods are only considering all brightness adaptation, without considering the temperature mutation effect on visual adaptation and physiological changes; at the same time, the entrance of brightness(Lth) and hole brightness(Lth(s)) directly affect the driver into the tunnel vision the adaptation process, but at present according to the determined entrance hole brightness brightness only extensive consideration of traffic flow and the design speed of two factors, in fact, the hole brightness and traffic is constantly changing, from outside to inside the natural light color of the light source color temperature mutation adaptation process of drivers also have an important influence, therefore, are no intelligent control system of lighting design parameters according to the traditional standard very well with the characteristics of human vision, there will be "excessive lighting" or "invalid The phenomenon of lighting ". At the same time, the change of color temperature can also result in some physiological feedback changes of the driver. In this paper, we review the literature about the development of tunnel smart lighting and the impact of driver's influence on the driver under the color temperature mutation, summarize the research results, analyze the research methods and technical means, and explore the research focus and development direction of tunnel smart lighting based on color temperature correction.
