教室照明改造可降低学生的近视率!

1.保持平均照度(lx)
1. Maintain average illuminance (LX)
普通教室、科学教室、语文教室、书法教室、音乐教室、劳动教室、史地教室、联合班教室、图书室、学生活动室、体质测试室、心理咨询室、德育展览室、舞蹈教室、实验室等15间教室的平均照度应大于等于300lx。美术教室、计算机教室、电子阅览室、教室黑板的平均照度应大于等于500lx。如果平均照度低于规定标准,长期 学习容易引起学生的视疲劳。
The average illuminance of 15 classrooms such as ordinary classroom, science classroom, Chinese classroom, calligraphy classroom, music classroom, labor classroom, history and geography classroom, joint class classroom, library, student activity room, physical fitness test room, psychological counseling room, moral education exhibition room, dance classroom and laboratory shall be greater than or equal to 300lx. The average illuminance of art classroom, computer classroom, electronic reading room and classroom blackboard shall be greater than or equal to 500lx. If the average illuminance is lower than the specified standard, long-term study is easy to cause students' visual fatigue.
2.统一眩光值UGR
2. Uniform glare value UGR
直射光线照在学生的眼睛上产生眩光。如果统一眩光值过高,会分散学生注意力,诱发近视。因此,,学校所有照明场所的统一眩光值应小于等于16。
Direct light glares on students' eyes. If the uniform glare value is too high, it will distract students' attention and induce myopia. Therefore, the uniform glare value of all lighting places in the school shall be less than or equal to 16.
3.显色指数Ra
3. Color rendering index ra
如果显色指数过低,会产生颜色失真,影响眼睛对物体颜色的正确辨别,长此以往会影响学生的辨色能力。因此,学校教室照明的标准显色指数值应大于等于80,美术教室应大于等于90。
黑板灯
If the color rendering index is too low, it will produce color distortion and affect the correct identification of object color by eyes. In the long run, it will affect students' color identification ability. Therefore, the standard color rendering index value of school classroom lighting should be greater than or equal to 80, and that of art classroom should be greater than or equal to 90.
4.均匀度U0
4. Uniformity U0
调查显示,我国学校教育照明环境存在照度均匀度低的问题,导致学生看不清东西,容易因视疲劳导致近视。因此,均匀性在教室照明中也是一个非常重要的指标。
The survey shows that the illumination uniformity of school education lighting environment in China is low, which leads to students' inability to see clearly and myopia due to visual fatigue. Therefore, uniformity is also a very important index in classroom lighting.
教室照明均匀度标准值应大于等于0.7,教师黑板应大于等于0.8。
The standard value of classroom lighting uniformity shall be greater than or equal to 0.7, and the teacher's blackboard shall be greater than or equal to 0.8.
5.照明功率密度
5. Lighting power density
照明功率密度决定着教室照明的节能性能,美术教室、计算机教室、电子阅览室的照明功率密度标准值应小于等于15。普通教室、科学教室、语文教室、书法教室、音乐教室、劳动教室、史地教室、联合教室、图书馆、学生活动室、体质测试室、心理咨询室、德育展览室、舞蹈教室、实验室照明功率密度标准值应小于等于9。
The lighting power density determines the energy-saving performance of classroom lighting. The standard value of lighting power density of art classroom, computer classroom and electronic reading room should be less than or equal to 15. The standard value of lighting power density of ordinary classroom, science classroom, Chinese classroom, calligraphy classroom, music classroom, labor classroom, history and geography classroom, joint classroom, library, student activity room, physique test room, psychological counseling room, moral education exhibition room, dance classroom and laboratory shall be less than or equal to 9.
