With the increasingly serious myopia of teenagers in China, China pays more and more attention to the transformation of classroom lighting. As a necessary lighting source for school classrooms, artificial light sources / lamps need to meet the following standards:

1. All classrooms shall be equipped with artificial lighting.

2. The average illuminance on the surface of classroom desks shall not be less than 300lx, and the illuminance uniformity shall not be less than 0.7.

3. Local blackboard lamps shall be set in the blackboard area of the classroom, and the average illuminance of its micro scale shall not be less than 500lx, and the illuminance uniformity shall not be less than 0.8.

4. The school classroom lighting should use the light source with the color temperature in the range of 3300K ~ 5500k, and the color rendering index should not be less than 80.

5. Fluorescent lamps for classroom lighting should adopt energy-saving inductive ballasts.

6. Naked lamps should not be used for school classroom lighting, and the minimum hanging height from the lamps to the class table should not be less than 1.7m, in order to reduce the direct glare caused by lighting.

7. The uniform glare value (UGR) of school classroom lighting should not be greater than 19.

8. When designing the illuminance of school classroom lighting, the maintenance coefficient shall be 0.8.

Therefore, in order to effectively avoid the impact of school lighting on students' vision, the school should adopt professional eye protection classroom lamps, and professional technicians should be responsible for the installation, so as to ensure that all indicators of classroom lamps and blackboard lamps can meet the qualified requirements, ensure that the light environment of each classroom is not only sufficient and excellent uniformity, but also minimize glare, To achieve no direct light into the student's eyes.
