【摘要】：光源因为其光谱分布不同而具有不同的色温,人眼对于不同的光谱和色温会产生不同的视觉响应。亮度水平是评价隧道照明质量的重要标准之一,而常常忽略光源色温对隧道照明效果的影响。因此,本文的研究重点为"在隧道照明的光环境中,定量分析光源色温对驾车人员视觉功能的影响"。由于高速公路隧道各段照明亮度水平涵盖了中间视觉范畴和明视觉范畴,所以本文分为低背景亮度和高背景亮度两种情况进行实验。在介绍人眼视觉形成过程后,总结出隧道照明环境下驾驶员的视觉反应特性。重点讨论了反应时间与交通事故的关系,为了保证隧道的出行安全,将"反应时间"作为评价光源光效的参数是非常重要而且必需的。在参考国内外有关资料的基础上,结合研究隧道照明的实际需要,设计并研制一套"反应时间测量系统"。通过该系统模拟隧道各段照明环境,测量人眼在不同实验条件下观测视标的反应时间。通过对实验数据进行回归分析,分别得到低背景亮度下和高背景亮度下,反应时间与光源色温的函数关系式,分析归纳出反应时间与背景亮度、视标对比度和视标偏心角的变化关系。通过对比发现,在低背景亮度下,光源色温对反应时间的影响程度要比在高背景亮度下的明显。最后,在中间视觉条件下,本文分析了人眼视亮度与光源色温之间的关系。在背景亮度一定的情况下,人眼视亮度随色温的升高而增加,增加的幅度和速度随着色温的增加而变小;随着背景亮度的增加,色温对人眼视亮度影响的规律不变,但影响程度变小。
[Abstract]:Because of its light source spectral distribution is different with different color, the human eye will produce different visual responses to different spectral brightness and color temperature. The level is one of the important standards to evaluate the quality of tunnel lighting, and often ignore the effects of light color temperature on tunnel lighting effect. Therefore, the focus of this article is "in the light of the tunnel lighting in the quantitative analysis of the influence of" the color temperature of the light source to drivers' visual function. Because each highway tunnel lighting brightness level covers the intermediate visual category and Ming visual category, so this paper is divided into the low background brightness and high background brightness of two kinds of experiments. In the formation process of visual references, summed up the visual response properties of lighting the driver under the tunnel environment. It focuses on the relationship between reaction time and traffic accident, in order to ensure the tunnel travel safety, "response time" as a commentary The price of efficient light source parameters is very important and necessary. Based on relevant data at home and abroad, combined with the actual needs of the tunnel lighting, designed and developed a set of "reaction time measurement system. Through the system simulation of tunnel segment lighting environment, measurement of human eye observation and reaction time as the standard in different experimental conditions. Through the regression analysis of experimental data, low background brightness and high background brightness were obtained under the function relation of the reaction time and the light source color temperature, analyzed and summarized the reaction time and the background brightness, visual target contrast and visual target changes in the relationship between the eccentric angle. By contrast, in low background brightness. Influence of color temperature on reaction time than in the high background brightness is obvious. Finally, under mesopic conditions, this paper analyzes the relationship between human visual brightness and color temperature of the light source in the background. Under the condition of certain brightness, the brightness of human eye increases with the increase of color temperature. The amplitude and speed increase with the increase of color temperature. With the increase of background brightness, the influence of color temperature on human eye brightness is unchanged, but the degree of influence is smaller.
