摘要
国际照明委员会(CIE)推荐的大学教室照明标准是照度大于5001x,平均显色指数(Ra)大于80.对东南大学新校区教室照明的实测结果表明,使用T8型日光色(色温6 500K)的卤粉荧光灯管,照度符合要求,显色指数为65,符合国家标准但未达到国际标准;在同等条件下改用中性白色(色温5 000K)的三基色节能荧光灯,照度提高30％～40％,显色指数为82,完全符合国际标准,同时得到了舒适的视觉环境,提高了视觉辨认能力和学习效率.
The CIE recommended average illuminance and color rendering index(CRI) for university classroom are greater than 500lx and 80 respectively.A test conducted in a classroom in the Southeast University showed that using halophosphate phosphor T8 fl uorescent lamps(6 500K),the illuminance met the CIE requirements and the CRI was 65,in line with the national standard but did not meet the international standard,and that under the same condition,using neutral white(5 000K) tricolor powder fl uorescent lamps,the illuminance increased by 30 to 40 percent and the CRI was 82,in full compliance with the international standard,at the same time,the comfortable visual environment improved the visual identifi cation ability and the learning effi ciency.
