本实验在三种照明条件下进行智力生产力评估：（a）常规环境照明，（B）正常色温（5000 K）的任务环境照明和（c）高色温（6200 K）的任务环境照明。在实验中，24名参与者被赋予认知任务。测定了集中程度的定量客观评价指标--集中时间比。结果表明，高色温任务环境照明下的平均集中时间比为72.5%，比常规环境照明下的平均集中时间比提高了5.0个百分点。人们相信，当集中时间比率高时，智力工作能更好地完成。
An experiment was conducted to evaluate intellectual productivity in three lighting conditions: (a) conventional ambient lighting, (b) task ambient lighting with normal colour temperature (5000K) and (c) task ambient lighting with high colour temperature (6200K). In the experiment, cognitive tasks were given to 24 participants. The concentration time ratio, which is a quantitative and objective evaluation index of the degree of concentration, was measured. The results showed that the average concentration time ratio under the task ambient lighting with high colour temperature was 72.5%, which was 5.0% points higher than that under the conventional ambient lighting. It is believed that intellectual work can be performed better when the concentration time ratio is high.
