目的了解北京市中小学教室照明状况及存在的问题,为卫生、教育部门指导学校改善照明环境提供参考,促进教学环境改善。方法 2006-2011年北京市各级疾病预防控制中心对全市1 500余所中小学校教室照明状况进行了3次监测。结果 2010-2011年北京市中小学校教室课桌面照度达标率仅为65.10%,黑板面照度达标的仅为23.76%;与2006-2007年度比较,课桌面平均照度增加了9.85个百分点,但距离国家标准的要求差距很大,改善效果不理想。此外,依据旧国家标准进行评价照明功率合格率为76.60%,黑板灯安装合格率为87.12%,提示国家标准已不能满足新形势的要求。结论北京市中小学校教室照明环境需要进一步改善。卫生部门应尽快修订照明的相关标准与方案,指导学校改善照明环境。
Objective To understand the lighting conditions and existing problems of classrooms in primary and secondary schools in Beijing and to provide reference for health and education departments to guide schools in improving lighting environment and to promote the improvement of teaching environment. Methods From 2006 to 2011, Centers for Disease Control and Prevention at all levels in Beijing conducted 3 monitoring of classroom lighting in more than 1,500 primary and secondary schools in the city. Results In 2010-2011, the standard of illumination of desk in classroom of primary and middle school in Beijing was only 65.10% and that of blackboard was only 23.76%. Compared with 2006-2007, the average illuminance of desk in classroom increased by 9.85% The difference between the standard requirements is great, and the improvement effect is not satisfactory. In addition, according to the old national standards for evaluation of lighting power pass rate was 76.60%, blackboard lamp installation pass rate was 87.12%, suggesting that national standards can no longer meet the requirements of the new situation. Conclusion The lighting environment of primary and secondary school classrooms in Beijing need to be further improved. Health authorities should amend lighting standards and programs as soon as possible to guide the school to improve the lighting environment.
