At present, there are some problems in classroom lighting: the illumination, color temperature and stroboscopic of most classrooms have not reached the national standard.
1. The illumination is seriously insufficient.
The illumination of the desks and blackboards in many schools in China is uneven. In particular, the average illumination of the blackboard is generally lower than that of the classroom desks, which can not meet the national standard. Children studying in this low illumination environment for a long time are easy to cause eye fatigue and affect their eyesight over time.
2. Severe glare.
The light source of many school classroom lamps is directly exposed, and the light directly enters people's eyes, which is very dazzling and has serious glare.
3. The color temperature is too high.
The color temperature standard specified in the national standard is 3300-5300k. According to a large number of investigations, many classrooms have reached 6000K, and the color temperature is too high, which will eventually affect the children's melatonin secretion, and then affect the learning efficiency.
4. The color rendering index is low.
After measurement, the color rendering index of most classrooms is about 70, which can not meet the national standard RA ≥ 80. In particular, the art room has high requirements for color rendering index.
5. Stroboscopic serious. Classroom lighting has serious stroboscopic, which has a great impact on vision.
6. Blue light hazard.
Studies have shown that learning environment light source is closely related to children's visual health. Reading, writing and learning should be carried out in an environment with good daylighting and sufficient lighting. For a long time in the substandard classroom lighting environment, they will have eye fatigue, resulting in myopia.
There are relevant national policies on classroom lighting, such as hygienic standards for lighting and lighting in primary and secondary school classrooms. In order to protect students' visual health, schools must pay attention to the layout of classroom lighting, improve the teaching visual environment, and create a high-quality lighting environment for eye protection classrooms in line with 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 "Huahui lighting"!
As a promoter of campus lighting light health, Huahui education lighting has been deeply engaged in the lighting industry for 26 years. It is the first batch of qualified units for classroom high-quality lighting environment in South China. It is also the "top ten education lighting brands" in China's lighting industry in 2021. It strictly controls the color temperature, glare, blue light, illumination and other problems in lighting to avoid the harm of bad lighting to students' visual health!
Huahui education 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 independently developed intelligent lighting products, equipped with the independently developed intelligent box (such as intelligent distribution box or intelligent air switch), the lighting mode meeting the needs of teaching can be easily switched by using the 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!
