| 摘 要： | 为研究道路常亮型LED补光灯对安全驾驶的影响，通过实测道路现场光照数据构建室内眼动实验，分析不同照度下被试者瞳孔大小的变化和视觉感受变化特征，为道路常亮型LED补光灯的照度设置提供依据。结果表明:道路常亮型LED补光灯光照强度变化对驾驶人员视觉有影响，光照强度从100×10-1 lx变化到700×10-1 lx时，被试者瞳孔逐渐缩小，但能看得清目标；光照强度从700×10-1 lx变化到1 700×10-1 lx时，被试者瞳孔进一步缩小，瞳孔缩小至约3.5 mm时开始看不清楚目标。为减小道路常亮型LED补光灯对驾驶人员的视觉影响，道路常亮型LED补光灯的照度应该设置在700×10-1 lx以下。

| Abstract: | In order to study the influence of road always-on LED supplementary lamp on the safe driving,the indoor eye movement experiment was constructed based on the measured illumination data of road field,and the changes in pupil size and visual perception characteristics of the subjects under different illumination levels were analyzed to provide the basis for the illuminance setting of the road always-on LED supplementary lamp.The results showed that the change of illumination intensity of road always-on LED supplementary lamp had an impact on the drivers’ vision.When the illumination intensity changed from 100×10-1 lx to 700×10-1 lx,the pupils of the subjects gradually shrunk,but the target could be seen clearly.When the illumination intensity changed from 700×10-1 lx to 1 700×10-1 lx,the pupils of the subjects shrunk further,and when the pupil shrunk to about 3.5 mm,the target could not be seen clearly.In order to reduce the visual impact of road always-on LED supplementary lamp on the drivers,the illumination of road always-on LED supplementary lamp should be set below 700×10-1 lx. |
