What is the impact of classroom lamps that do not meet the lighting standards on students' eyesight?

2021-07-20

With the change of life style, the myopia rate of students is higher and higher. Classroom is the longest place for students to stay. If the lighting environment is not well done, it will seriously affect the students' vision. Therefore, it is very important to use LED eye protection lamp to improve the lighting of classroom.

If the classroom lighting environment is not up to standard, what effect will the lamp have on the eyes?

1. The illumination and illumination uniformity of the desk are generally lower than the national standard (national standard: the illumination of the desk is not less than 300lx, and the illumination uniformity is not less than 0.7). If students are in low illumination for a long time, the illumination received by different desks in the same classroom is uneven, some students are hard to read, read and write, which may cause visual fatigue.

2. The blackboard lighting is not used, even the blackboard lighting is not arranged, which results in the average illuminance of blackboard far lower than the national standard (national standard: blackboard illumination is not less than 500lx, uniformity is not less than 0.8), and some students can not see the words on the blackboard easily visual fatigue and lead to myopia.

3. Most of the fluorescent tubes directly installed in the classroom, the light directly direct to the students' eyes, resulting in glare, distract the students' attention, thus affecting the learning efficiency, causing visual fatigue and myopia. And fluorescent lamps are generally equipped with inductive ballast, there is a serious stroboscopic effect. In order to adapt to the frequency change, the students' visual system will also adjust automatically frequently, which causes visual fatigue.

4. The color index is too low. Most classrooms adopt fluorescent lamp color index of about 70 (national standard: the color index of light source should not be less than 80), which causes color distortion and makes the object unable to present the color in real.

5. Most classrooms generally use high color temperature (6500k) fluorescent lamp (national standard: 3300-5500k color temperature light source should be used in classrooms), which has blue light hazards. High color temperature because the light color is too white, eyes are easy to fatigue.

Therefore, to create a high-quality lighting environment for students, all primary and secondary schools and institutions (including: public school classroom lighting, private school classroom lighting, private school classroom lighting, experimental school classroom lighting, education institutions, etc.) are recommended to choose the "Huahui lighting" brand!
