At present, the myopia rate of primary and secondary school students remains high. In the experiment of the National Natural Science Foundation Project "Research on classroom health lighting based on photobiological effect", it is more scientifically shown that school classroom lighting will directly affect students' learning efficiency and vision health.
At the same time, the education industry has also issued relevant standards, such as hygienic standards for lighting and lighting in primary and secondary school classrooms, work plan for myopia prevention and control of primary and secondary school students, hygienic standards for lighting and lighting in primary and secondary school classrooms, and so on.
So what are the standards of classroom lighting?
1. Excellent illumination
The illuminance of classrooms and classrooms should not be lower than the average illuminance of l7.0 in the standard of hygiene, and the illuminance of classrooms and classrooms should not be lower than that of the standard of hygiene; The blackboard in the classroom shall be equipped with local lighting, the average illumination value shall not be less than 500lx, and the illumination uniformity shall not be less than 0.8.
2. Anti glare
The hygienic standard for daylighting and lighting in primary and secondary school classrooms points out that the unified glare value (urg) of the classroom should not be greater than 19. The glare value of traditional T8 bracket fluorescent lamp and led ordinary lamp without glare treatment is greater than 20, which is dazzling. Learning in this environment for a long time will cause students to feel dizzy.
3. High color rendering index
The hygienic standard for daylighting and lighting in primary and secondary school classrooms points out that the color rendering index of classroom lighting light source should not be less than 80, and if the color rendering index is less than 80, the picture will be distorted.
4. No stroboscopic hazard
Stroboscopic has a great impact on vision, which is easy to distract students' attention and reduce the efficiency of learning. Learning in a stroboscopic environment for a long time is also easy to cause visual fatigue.
5. Moderate color and temperature
It is pointed out in the hygienic standard for daylighting and lighting in primary and secondary school classrooms that 3300k-5500k color temperature light sources should be used in classrooms.
6. No blue light hazard
"Blue light" mostly exists in ordinary LED lamps. If it is not treated against blue light, it is harmful.
Whether it is new or old classroom reconstruction, the classroom lighting should meet the national standards. It is recommended that all primary and secondary schools and institutions (including public school classroom lighting, private school classroom lighting, private school classroom lighting, experimental school classroom lighting, educational institutions), classroom lamp OEM and OEM choose the "Huahui lighting" brand!
As a promoter of Campus Lighting health, Huahui lighting has been deeply engaged in the lighting industry for 27 years. It is the first batch of qualified units for high-quality lighting environment in classrooms in South China. It is also the "top ten educational lighting brands" in China's lighting industry in 2021. It strictly controls the color temperature, glare, blue light, illumination and other problems in educational lighting to avoid the harm of bad lighting to students' visual health!
Huahui lighting has designed special lighting fixtures for classroom - led eye protection classroom lamp and led eye protection blackboard lamp, which meet the national standard. The average (constant) illumination of the desk is greater than 300lx and the uniformity of illumination is 0.7; The blackboard maintains an average (constant) illumination of 500lx, and the illumination uniformity is 0.8; The color rendering index is greater than 90, and the color reduction is high; The grid anti glare design is adopted, and the glare value is less than 16, which is not dazzling; The color temperature is 5000K, comfortable and soft; The illumination of the whole classroom is uniform, without stroboscopic and blue light hazards.
The use of Huahui led eye protection classroom lamp and led eye protection blackboard lamp can be combined with Huahui education lighting aiot intelligent education lighting overall solution. Through the self-developed intelligent lighting products, equipped with self-developed intelligent boxes (such as intelligent distribution box or intelligent air switch), the lighting mode suitable for teaching can be easily switched by using intelligent full touch screen scene switch, remote control or mobile phone app, Realize the intelligent requirements of constant illumination, one key scene control, curtain linkage, ultraviolet sterilization and so on!
