What kind of lights are used for classroom lighting to meet the national standards?
At present, the myopia rate of primary and middle school students is still high. More and more people are advocating to pay attention to the improvement of eyesight of students and the healthy lighting of classrooms. Parents of students and classrooms pay special attention to them. The education industry has also issued relevant standards. So what kind of lights are generally used for classroom lighting in line with the country standard?
According to professionals, classroom lights that meet national standards must have six standards: excellent illuminance, no glare, high color rendering index, no light strobe hazard, moderate color temperature, and no blue light hazard; when the educational lighting is accepted, it is also Test these six standards.
So, if the six standards of educational lighting are not up to standard, what harm will it bring?
1. What harm will the low illumination of educational lighting bring?
The "Hygienic Standards 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 underneath unconsciously, causing the eyes to be too close to the books. If you often read books at such close distances , Writing, it will make the adjustment of the eyes abnormally tight, thus forming myopia.
Benwei Lighting's smart LED classroom lamps (classroom lights and blackboard lights) have a uniform illuminance greater than 0.95. The average illuminance value on the classroom desktop is 300lx, and the classroom blackboard maintains an average illuminance value of 500lx. The entire classroom environment is bright and effectively prevents myopia.
2. What harm will the glare of education lighting bring?
The "Hygienic Standard 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.
The color rendering index of the eye protection classroom lamp produced by Benwei Lighting reaches Ra>90, which meets the classroom lighting standard Ra>80, which is closer to natural light. In addition, Benwei Lighting's classroom eye protection lamp has no flicker, uniform illumination, bright and soft light, energy saving and environmental protection, which can help schools reduce maintenance costs.
3. What harm will the low color rendering index of educational lighting bring?
The "Hygienic Standards for Daylighting and Lighting of Classrooms in Primary and Secondary Schools" pointed out that the color rendering index of the classroom light source should not be less than 80. Too low color rendering index affects the students' eyesight to recognize the color of the object, so that the object cannot show its true color. If this situation continues, it will easily cause students' color blindness or color weakness.
Benwei Lighting’s smart LED classroom lamps use RG0’s special anti-blue light brand lamp beads for classrooms. Ra>90 has high color reproducibility and can clearly identify colors without causing color blindness or color weakness in students.
4. What kind of harm will the education lighting strobe bring?
Light strobe is easy to distract students and reduce the efficiency of learning. In order to adapt to the frequency changes of the lights, students’ eyes need to be constantly adjusted independently. If they continue for a long time, the eyes will be extremely fatigued.
The smart LED classroom lamps of Benwei Lighting can realize stepless dimming and color adjustment, without causing eyesight fatigue, and effectively improving the efficiency of learning.
5. What kind of harm will the high and low color temperature of educational lighting bring?
The "Hygienic Standard for Daylighting and Illumination 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 easily leads to excitement of the students. Once the excitement is over, it will cause visual fatigue, reduce concentration and reduce learning efficiency.
The color temperature of the smart LED classroom lamps of Benwei Lighting is controlled at 4000K-5500K stepless dimming, which is close to the sun, which will not cause visual fatigue and effectively improve the learning efficiency.
6. What kind of harm will the education lighting bring about without the 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.
