What are the requirements for classroom lighting? Education lamp manufacturers inform you

What requirements should be followed for school classroom lighting? The educational lamp manufacturer informs you that it is the same as natural lighting, preventing glare and preventing harmful light; the "Lighting and Lighting Hygiene Standard for Primary and Secondary Schools" promulgated by the Ministry of Health requires that the average illuminance of the classroom desktop should be as high as 300LX. So what are the suitable conditions for school classroom lighting? Under natural or artificial light conditions, the effects of different illuminances on visual function are significantly different.

1. In terms of natural light:

Below 20LX, visual fatigue is more serious;

Under the condition of 60LX, the degree of visual fatigue decreased significantly;

At 180LX, visual fatigue is less.

2. In terms of artificial light:

The average illuminance value should not be less than 300Lx;

The color temperature should be kept in the range of 2700K~7000K;

As a necessary source of lighting for school classroom lighting, artificial light sources/lighting fixtures must meet the following standards:

1. All classrooms should be equipped with artificial lighting.

2. The average illuminance value of the classroom desktop should not be lower than 300Lx, and the illuminance uniformity should not be lower than 0.7.

3. The classroom blackboard should have local lighting, the microscopic average illuminance should not be lower than 500Lx, and the illuminance uniformity should not be lower than 0.8.

4. School classroom lighting should use a light source with a color temperature of 2700K to 7000K, and the color rendering index should not be lower than 80.

5. School classroom lighting should use small tube lights less than 26mm.

6. Fluorescent lamps for classroom lighting should use energy-saving inductors.

7. School classroom lighting should not use bare lamps. The small hanging height of the lamps on the table should not be less than 1.7 meters. The aim is to reduce direct glare caused by lighting.

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

9. Under the condition of maintaining the average illuminance value of 300Lx, the power density of school classroom lighting should not exceed 11W/m2, and the target value should be 9W/m2.

10. When the school classroom lighting design lighting, the maintenance system effect is 0.8.
