目的了解北京市中小学教室照明现状及存在的问题,为卫生、教育部门指导学校改善教学环境提供参考。方法 2007年3月1日-4月15日采用典型抽样的方法,从北京市4个区县抽取80所中小学校160间教室进行夜间照明检测,评价学校照明现况及不同类型灯管照明效果。选取一间教室进行现场试验,探索应用GB 50034-2004《建筑照明设计标准》的操作建议。结果中小学教室课桌面平均照度为(264.9±118.9)lx,合格率(≥300 lx)为33.7%,照明功率密度P50为7.3 W/m2,黑板面照度P50为268.7 lx,合格率(≥500lx)为16.7%。结论目前中小学教室照明情况较之以前有整体提高,同时也存在一些问题,需要进一步改善。
Objective To understand the present situation and existing problems of classroom lighting in primary and secondary schools in Beijing and to provide reference for health and education departments to guide schools to improve their teaching environment. Methods From March 1, 2007 to April 15, 2007, 160 classrooms of 80 primary and secondary schools were sampled from 4 districts and counties of Beijing for the nighttime illumination detection using the typical sampling method to evaluate the status of school lighting and the lighting effects of different types of lamps . Select a classroom for field experiments to explore the application of GB 50034-2004 “architectural lighting design standards” operating recommendations. Results The average illuminance of desktop in primary and secondary schools was (264.9 ± 118.9) lx, the pass rate (≥300 lx) was 33.7%, the illumination power density P50 was 7.3 W / m2, the blackboard illumination P50 was 268.7 lx, the pass rate ) Is 16.7%. Conclusion At present, the lighting in classrooms in primary and secondary schools is generally higher than before. At the same time, there are still some problems that need to be further improved.
