High quality lighting environment in the classroom: first of all, we should do a good job in the reference of natural light, mainly natural light, supplemented by artificial lighting. The second is the color temperature. The lighting with high color temperature is uncomfortable for most people. Finally, there is the problem of blue light. We should control the content of blue light. We also need to pay attention to the spatial brightness of the classroom, the stroboscopic and dazzling problems of lighting lamps, as well as physical health and other factors.
According to statistics, the incidence of myopia among Chinese students ranks first in the world. Primary and middle school students in China spend about 8-10 hours in the classroom every day. Studies have shown that in addition to the heavy burden of schoolwork, poor classroom lighting is one of the main reasons for the decline of students' vision. Therefore, it is very important to choose high-quality lighting and light environment in the classroom!
So, what are the effects of poor classroom lighting on vision health?
The high stroboscopic lighting in the classroom leads to the continuous opening and closing of the pupil sphincter, causing students' eye fatigue and vision loss. The color rendering index of classroom lighting is low, and the spectrum of ordinary fluorescent lamps is incomplete, which will lead to color loss and color deviation, which is far from reaching the national standard RA ≥ 80. However, the color restoration ability of lighting lamps is poor, which will directly affect children's color discrimination ability.
The color temperature of classroom lighting is high and the light is white. According to the national standard, the light with 3300k-5500k color temperature should be used in the classroom. The color temperature of the light in most school classrooms is about 6500k, and the light is white, which is easy to lead to students' hyperactivity and fatigue, and cause students' myopia for a long time.
If the school wants to have high-quality lighting environment in the classroom, it is recommended to choose "Huahui lighting" brand! 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 brand of "Huahui lighting"!

It is the first batch of qualified units for classroom high-quality lighting environment 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 is specially used for classroom lighting lamps - 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!
