Myopia prevention and control! Classroom lighting is very important!


From kindergarten to high school graduation, the classroom has been one of the main places to accompany children's growth for 15 years. The good or bad lighting environment in classrooms directly affects children's eye health and learning efficiency.

Classroom lighting often affects students' learning. The lighting problems in the classroom, such as prominent glare, poor uniformity of desk illumination during the day, low color rendering of lighting fixtures, and unsatisfactory shading and utilization of sunlight, not only damage students' visual health, but also affect their learning efficiency.


Huahui Lighting has designed specialized lighting fixtures for classroom lighting. The Huahui LED eye protection classroom lights and LED eye protection blackboard lights comply with and are superior to the "Hygienic Standards for Daylighting and Lighting in Primary and Secondary School Classrooms". The lighting technology is mature and meets national certification requirements such as CCC and CE. The entire lamp uses RG0 classroom dedicated anti blue light beads, with a glare value of less than 16, a color temperature of 5000K, and Ra>95, to ensure uniform classroom illumination, effectively protect vision, and prevent myopia.


Good classroom lighting and lighting must comply with national standards. What are the requirements for classroom lighting and lighting?

1. Classroom lighting

The orientation of the school classroom should adopt north-south dual lighting. When the classroom adopts one-sided lighting, the light should come from the left side of the student seat. The minimum value of lighting coefficient on the class desk should not be less than 2%. The ratio of classroom window to floor area should not be less than 1:5.

2. Anti glare measures

To prevent direct glare from windows, classrooms should have curtains to prevent direct sunlight from entering the classroom. To prevent the reflection glare of the blackboard, its surface should be made of wear-resistant and matte materials.

3. Classroom blackboard light

The classroom blackboard should be equipped with locally controlled lighting fixtures, which should maintain an average illumination value of not less than 500LX and an illumination uniformity of not less than 0.8. The blackboard should be made of wear-resistant and matte materials.

4. Classroom lighting fixtures

Naked lighting should not be used in classrooms. The lamp should be equipped with a lampshade, and the hanging height of the lamp from the desktop should not be less than 1.7m. The arrangement of lamp tubes should be arranged with their long axis perpendicular to the blackboard surface. The average illumination value maintained on the class desk should not be less than 300lx, and the uniformity of illumination should not be less than 0.7.


As a promoter of campus lighting and health, Huahui Lighting has been deeply involved in the lighting industry for 28 years. It is one of the first units to meet the standards for high-quality lighting environment in classrooms in South China and also one of the "Top Ten Education Lighting Brands" in the lighting industry in China in 2022. It strictly controls color temperature, glare, blue light, illuminance, and other issues in educational lighting to avoid harmful lighting to students' visual health.
