If the six standards of educational lighting are not up to standard, what harm will it bring?
1. What harm will the low illuminance of education lighting bring?
The "Hygienic Standard for Daylighting and Illumination of Classrooms in Primary and Secondary Schools" pointed out that all classrooms should be equipped with artificial lighting, and the average illuminance value on the classroom desktop should not be less than 300lx, and the uniformity of illuminance should not be less than 0.7; classroom blackboards should be Set up local lighting, which maintains the average illuminance value not less than 500lx, and the uniformity of illuminance should not be less than 0.8. If the classroom lighting is far below the standard value, the pupils of the eyes will be opened to the maximum, and in order to take in enough light, the student's head will be under the head unconsciously, causing the eyes to be too close to the book. If you often read the book at such close distance , Writing, it will make the adjustment of the eyes abnormally tight, thus forming myopia.
2. What harm will the glare of education lighting bring?
The "Hygienic Standards for Daylighting and Lighting of Classrooms in Primary and Secondary Schools" pointed out that the uniform glare value (URG) of the classroom should not be greater than 19, and the eyes will be blinded by strong light for a long time.
3. What harm will the low color rendering index of educational lighting bring?
The "Hygienic Standard for Daylighting and Lighting of Classrooms in Primary and Secondary Schools" points out that the color rendering index of the classroom light source should not be less than 80. Too low color rendering index affects students' eyesight to recognize the color of objects, so that the objects cannot show their true colors. If this situation continues, it is very easy to cause students' color blindness or color weakness.
4. What kind of harm will the education lighting strobe bring?
Light strobe can easily distract students and reduce the efficiency of learning. In order to adapt to the frequency changes of the lights, students’ eyes need to be continuously adjusted independently. If they continue for a long time, the eyes will be extremely fatigued.
5. What kind of harm will the high and low color temperature of education lighting bring?
The "Hygienic Standard for Daylighting and Lighting of Classrooms in Primary and Secondary Schools" points out that classrooms should use light sources with a color temperature of 3300K-5500K. When the color temperature is high, the light color is too white, which will easily lead to excitement of the students. Once the excitement is over, it will cause visual fatigue, reduce concentration and reduce learning efficiency.
6. What kind of harm will education lighting bring if there is no blue light hazard?
The blue light referred to in educational lighting is a kind of high-energy visible light, among which short-wave blue light has a relatively high energy light. Blue light within this wavelength will increase the amount of toxins in the macular area of the eye and seriously threaten the health of the fundus. Due to the short wavelength of blue light, the focus point does not fall on the center of the retina, but a little bit forward from the retina. To see clearly, the eyeballs will be in a state of tension for a long time, causing eyesight fatigue.
Therefore, classroom lighting needs to carefully choose educational lighting fixtures. Huahui smart educational lighting fixtures are recommended. They are not only anti-blue, but also intelligent anti-blue LED classroom lights. The lighting can be controlled by panel switches, remote controls, and mobile phones. Smart campus, energy-saving and environmentally friendly, while also providing a healthy lighting environment for teachers and students, it really serves multiple purposes!
