Experts from the national optometry Engineering Technology Research Center pointed out that 7-12 years old, that is, the whole primary school stage, is the golden period for myopia prevention and control. In the lower grade of primary school, students need to adapt to the change of environment and role. The prevention and control of myopia should focus on developing good habits, pay close attention to the development of vision and protect their vision. In the upper grade of primary school, we should pay attention to eye hygiene and scientifically prevent and control the occurrence and development of myopia.

However, the existing classroom lighting conditions are lagging behind. In the survey, it is found that many schools use ordinary fluorescent lamps for lighting, and the average illuminance of most classrooms is below 200lx. These lights have a series of unhealthy factors affecting students' vision, such as low illuminance, blue light, stroboscopic, glare, mercury pollution and so on.

With the attention of relevant national policies, the transformation of classroom lighting environment is in full swing all over the country. However, we found that even if some classrooms were replaced with special lamps for the classroom, the lighting quality was unqualified. So, what kind of classroom lighting can effectively prevent children and adolescents from myopia?

The transformation of classroom lighting should not be understood as "replacing old lamps with new lamps", but an overall solution to the lighting environment, including professional lighting design based on real space scenes and the needs of different people, photobiology theory, high-quality lamps and light sources, refinement of intelligent control and so on.

Special LED eye protection classroom lamps should be selected for classroom lighting transformation. 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 health, Huahui lighting 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 2020. It strictly controls the color temperature, glare, blue light, illumination and other problems in educational lighting to avoid the harm of bad lighting to children's 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) illuminance of the desk is greater than 300lx and the illuminance uniformity 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 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 that meets the needs of 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!
