摘　　要：对比不同色温荧光灯光源作为背景光源,在视标光源统一为白炽灯的条件下受试人的视功效表现,以了解背景光源色温对受试人视功效的影响;寻找出在同等亮度、对比度条件下,可有效提高受试人识别率的背景光源,为教室照明光色选择提供实验参考。实验以"参考人"视功效曲线为基准,以受试人平均识别率高低为指标来判断光源光谱及色温的实际视功效表现。This study examines the visual performance of subjects in a classroom chalkboard illuminated by incandescent lamps and ambient classroom lighting with various T5 fluorescent lamps.By using different colour fluorescents for ambient lighting,the visual performance and recognition rate can be maintained or enhanced with the same luminance level and luminance contrast.The visual performance curve of the base ＂reference person＂and their average recognition rate establishes the evaluation criteria for determining the effect of light source＇s spectrum and colour appearance.
