摘要
为对未来的VDT办公光环境设计提供合理建议,实验对比研究了具有适应性的恒定(水平照度500 lx,垂直照度300 lx,色温3800 K)、非偏好动态及偏好动态三种VDT办公光环境对被试的作业效率、注意力、记忆力、对比敏感度、色觉、远视力、近视力及自觉症状的影响。实验结果表明:被试在恒定光环境下的注意力、记忆力、对比敏感度及远、近视力的表现更好;在偏好动态光环境下,自觉症状的评价、色觉表现更好;而相比之下,在非偏好动态光环境下适应性最差。故未来的VDT办公光环境设计中应避免采用忽略个体差异的动态办公照明,并应根据VDT作业内容,在恒定与偏好动态照明间进行合理选择。
The comparative experimental study was done to provide reasonable suggestions for the future office lighting environment design for VDT work.It studied the effects of three kinds of lighting environment for VDT work on the subjects’operational efficiency,attention,memory,contrast sensitivity,color sense,far and near vision and conscious symptoms.The three light environments were constant lighting environment(horizontal illumination was 500 lx,vertical illuminance was 300 lx,color temperature was 3800 K),non-preference dynamic lighting environment and preferred dynamic lighting environment.The results showed that the subjects’attention,memory,contrast sensitivity and distant and near vision were better under the constant lighting environment;their evaluation of conscious symptoms and color vision were better under the preferred dynamic lighting environment;the adaptability was the worst under the non-preference dynamic light environment.So designers should avoid using the dynamic office lighting which ignores individual differences under the unified dimming control in the future office lighting design for VDT work.In addition,designers should make a reasonable choice between the constant office lighting environment and the preference dynamic office lighting environment according to the specific content of VDT work.
