Abstract

Objective: This study aims to analyze the effect of correlated color temperature from LED glare sources on driving performance. The evaluation includes assessing the effect of disability glare on visual reaction time and rating discomfort glare using a standardized scale.

Background: LED technology is widely incorporated into various lighting systems; however, the impact of glare from oncoming car headlamps on driving performance at night-time is crucial for road safety.

Method: Twenty-three healthy young subjects participated in a laboratory-based experiment simulating night driving using a two-channel Maxwellian view optical system. Two LED lamps with correlated color temperature of 2800 K and 6500 K were used to generate a glare of 52 lx. Disability glare was quantified in terms of foveal reaction time and discomfort glare was rated using the de Boer scale.

Results: The results show that glare-induced effect is mitigated by an increase in background luminance. The correlated color temperature of the LED lamp does not affect either reaction time or discomfort glare rating.

Conclusion: The greater short-wavelength emission of 6500 K lamp does not intensify the effect of disability or discomfort glare, probably due to the macular pigment absorption on foveal vision and the transparency of ocular media, coupled with the involvement of other contributing factors. The correlated color temperature of the lamp is not the best descriptive parameter to identify its effect on glare.

Application: It is important to consider the impact of LED technology on visual performance to enhance road safety in critical glare situations during night driving.

夜间行车的眩光：Led灯相关色温的影响

目的：分析LED眩光源相关色温对驾驶性能的影响。评估包括评估残疾眩光对视觉反应时间的影响，并使用标准化量表评定不适眩光。背景：LED技术被广泛应用于各种照明系统；然而，迎面而来的汽车前照灯的眩光对夜间驾驶性能的影响对道路安全至关重要。方法：23名健康青年受试者采用双通道麦克斯韦视光学系统进行夜间驾驶模拟实验。使用相关色温分别为2800 K和6500 K的两个LED灯，产生52 lx的眩光。失能眩光以中央凹反应时间量化，不适眩光以de Boer量表评定。结果：背景亮度的增加可以减轻眩光引起的效应。LED灯的相关色温既不影响反应时间，也不影响不适眩光等级。结论：6500k灯短波长较大的发射强度并不会加剧致残或不适眩光的影响，这可能与黄斑色素吸收对中央凹视力和眼介质透明度的影响有关，再加上其他因素的参与。灯的相关色温并不是确定其对眩光影响的最佳描述参数。应用：考虑LED技术对视觉性能的影响是很重要的，以提高夜间驾驶时在严重眩光情况下的道路安全。

期刊介绍： Human Factors: The Journal of the Human Factors and Ergonomics Society publishes peer-reviewed scientific studies in human factors/ergonomics that present theoretical and practical advances concerning the relationship between people and technologies, tools, environments, and systems. Papers published in Human Factors leverage fundamental knowledge of human capabilities and limitations – and the basic understanding of cognitive, physical, behavioral, physiological, social, developmental, affective, and motivational aspects of human performance – to yield design principles; enhance training, selection, and communication; and ultimately improve human-system interfaces and sociotechnical systems that lead to safer and more effective outcomes.
