摘　　要：为了研究驾驶舱不同灯光色温对视觉疲劳的影响,在A320仿真驾驶舱内进行色温灯光试验,使被试处于3000~3500 K、4000~4500 K及6000~6500 K色温灯光环境下,采用主观视觉疲劳量表(VFSES)、视觉舒适度量表(VCS)和闪光融合临界频率仪(CFFD)对被试的视觉舒适度和疲劳程度进行连续测量。采用单因素方差分析和描述性统计的数据分析方法,对被试处于不同灯光环境下的主观疲劳程度、视觉舒适度和闪光临界频率值的差异和变化趋势进行分析和评价。结果表明:随环境灯光色温增加,被试的主观疲劳程度逐渐降低、视觉舒适度逐渐升高;在中色温灯光环境下(接近自然光)被试的客观视觉疲程度最低,提高灯光色温(接近自然光)可有效提高视觉舒适度、降低视觉疲劳。To study the influence of different light color temperatures in the cockpit on visual fatigue,the experiment of color temperature lighting was carried out in the A320 simulation machine,and participants were exposed to 3000-3500 K,4000-4500 K,and 6000-6500 K color temperature lights.Every half an hour,we used the Visual Fatigue Subjective Evaluation Scale(VFSES),the Visual Comfortable Scale(VCS),and the Critical Flicker Frequency(CFF)to continuously measure data on subjective fatigue degree,visual comfort,and critical flicker frequency values of participants in different lighting environments.The difference and variation trend of subjective fatigue degree,visual comfort,and critical flicker frequency of participants under different lighting environments were evaluated and analyzed by using one-way analysis of variance and descriptive statistics.One-way analysis of variance was performed by SPSS,and it was found that there were significant differences among the three evaluation indexes of the participants under different lighting conditions(p<0.05).The results show that the subjective fatigue score and visual comfort score of participants show an overall trend of increase with the increase of time.The trend line of both of them is that the low color temperature is at the top,the medium color temperature is at the middle,and the high color temperature is at the bottom.While the critical flicker frequency value of participants shows an overall trend of decrease and the decline rate of the critical flicker frequency value of low color and high color temperature is higher than that of the medium color temperature.With the increase of the ambient light color temperature,the subjective fatigue degree of the participants decreased gradually and the visual comfort degree increased gradually.The participants had the lowest degree of objective visual fatigue under the lighting environment of medium color temperature(similar to natural light)and both low color and high color temperature lighting environments increase the obj
