摘　　要：目的探究夜间照明环境对电纸书阅读工效及视疲劳的影响,探索更有益于用户生理与心理的照明方式及相对应的照明参数。方法采用内外置照明方式对比实验,以视觉搜索绩效和瞳孔直径变异系数分别作为阅读工效与视疲劳症状的评价指标,结合主观生理评价指标作为对照。结论在两种照明方式下,照度为350 lux时阅读绩效最高,且视疲劳程度更大。从主观生理感受评价可知,内置照明方式下采用最低照度150 lux时被试感到麻木,使用外置照明方式被试整体感受较好,头晕与眼部疲劳症状不明显。综合可得,外置照明方式在阅读工效以及视疲劳症状上优于内置照明方式。The paper aims to explore the effects of night lighting on the reading efficiency of e-book and the visual fatigue of subjects,and to explore the ways of lighting and corresponding lighting parameters which are more beneficial to the users'physiological and psychological conditions.Internal and external illumination contrast experiments were compared.The visual search performance and pupil diameter variation coefficient were used as evaluation indicators for reading ergonomics and visual fatigue symptoms respectively,and subjective physiological evaluation indexes were taken as the control.Under two lighting modes,the reading performance is the highest at an illumination of 350 lux and the visual fatigue is more serious.From the subjective physiological experience evaluation,the subjects will feel numbness at the minimum illumination of 150 lux under the built-in lighting method,and the overall feeling of the subjects using the external lighting method is good,and the symptoms of dizziness and eye fatigue are not obvious.In conclusion,external lighting is superior to built-in lighting in reading ergonomics and visual fatigue symptoms.
