artificial illumination
The classroom must be equipped with artificial lighting to ensure the lighting quality.
The average illuminance is up to standard.
The average illuminance on the desk should be at least 300lx, and the illuminance should be uniform to ensure the students' eyesight health.
Blackboard lighting meets the standard.
The local lighting of the blackboard should reach 500lx to ensure that every student can see clearly.
Color temperature and color rendering index
The color temperature is between 3300 K and 5500 K, and the color rendering index cannot be lower than 80, which ensures the natural and comfortable lighting effect.
Glare value
The glare value (UGR) should be less than 19 to ensure the lighting quality.
lighting power density
Under the average illumination of 300lx, the current value of lighting power density shall not exceed 1 1W/m? , to ensure energy conservation and environmental protection.
Maintenance coefficient
The maintenance coefficient is 0.8 to ensure the normal operation of lighting facilities.
legal ground
Article 5 of the Education Law of the People's Republic of China clearly points out that governments at all levels and relevant departments, parents or other legal guardians of school-age children and schools have the responsibility to ensure children's right to receive and complete compulsory education. This is not only a legal requirement, but also a responsibility for every child's future.
Create a bright and comfortable learning environment
I hope every parent and school can strictly abide by these standards and create a bright and comfortable learning environment for their children!
