工作面混合照明对书面阅读工效的影响

Study on the Influence of Work Surface Mixed Illumination on literal Reading Efficiency

目的寻找最优的工作面混合照明,使得书面阅读工效最高。方法以12名在校大学生为被试,采用4(环境照度:0 lx、100 lx、150 lx、300 lx)×4(局部照度:200 lx、300 lx、500 lx、750 lx)双因素设计,研究不同环境照度和局部照度组合对书面阅读工效的影响,并对被试进行混合照度的主观评价。结果局部照度对阅读工效有显著性影响,环境照度对阅读工效无显著性影响。结论当环境照度相对较低,局部照度相对较高时,视觉感受、主观感受等方面均较好;当环境照度为150 lx,局部照度为300 lx时,书面阅读工效最佳。

Objective In order to improve the literal reading efficiency, the mixed illumination of working surface was investigated. Methods 12 college students were asked as subjects to investigate the effect of the mixed illumination of working face on the literal reading efficiency in detail by two factor designs of 4 ambient light illuminations （ 0lx, 100lx, 150lx, 300lx） with 4 local illumination （200lx, 300lx, 500lx, 750lx）. Subjective assessment of mixed illumination has been made on the subjects. Results The experimental results indicated that the local illumination had a significant effect on literal reading efficiency, whereas, the environmental illuminations had no obvious effect on reading efficiency. Conclusion As a result, when the environmental illumination was relatively low, the local illumination was relatively high, the visual perception and subjective feeling were better. And when the environmental illumination was about 150lx, the local illumination 300lx, the mixed illumination of working face was the best and achieved a highest literal reading efficiency.
