In May 2020, the joint defense joint control mechanism of the State Council held a press conference on scientifically using eye and preventing myopia. Guo Xin, director of the school health center of Beijing City Center for Disease Control and prevention, invited the reporter's question, "guidelines for the prevention of myopia in children and adolescents during the COVID-19", to mention: how should the school maintain the daylighting conditions of the classroom to protect students' eyesight? An explanation is given.

Director Guo pointed out that at the beginning of the building, the daylighting of the school should be designed according to the daylighting and lighting standards of primary and secondary school classrooms, and the school should do a good job in maintenance, not once and for all. The maintenance coefficient of lamps should be more than 0.8, the windows and lamps should be cleaned regularly, and the classroom wall should be kept clean. We often just installed in the classroom lighting, illumination, all aspects are qualified, after a period of time will not be qualified. This involves the maintenance factor, including the need to wipe the lamp regularly and once a month.

At present, most schools use fluorescent tubes or ordinary LED tubes as lighting lamps. Lighting glare, stroboscopic serious, color difference, illumination and illumination uniformity can not meet the requirements of the national standard, and the color temperature is too high, it is easy to induce myopia, high energy consumption, long-term maintenance and other problems, but also cost the school a lot of effort, mainly as an important place in students' daily study and life, the classroom lighting environment directly affects the students' visual health and learning efficiency.

Studies have shown that poor lighting environment is an important factor leading to myopia. Reading, writing and learning should be carried out in a well lit environment. In the substandard classroom lighting environment, students will have eye fatigue, resulting in myopia.

Therefore, 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, etc.) are recommended to choose "Huahui lighting" to effectively prevent myopia!

As a school lighting health promoter, Huahui lighting is one of the first batch of high-quality classroom lighting units in South China. It is also one of the "top ten education lighting brands" in China's lighting industry in 2020. It strictly controls the color temperature, glare, blue light, illumination and other problems in education lighting, so as to avoid harmful lighting to students' eyesight health!

Huahui lighting has designed led eye protection classroom lamp and led eye protection blackboard lamp, which are specially used for classroom lighting. They meet the national standard. The average (constant) illumination of desks is greater than 300lx, and the illumination uniformity is 0.7; The blackboard maintains an average (constant) illumination of 500lx, and the uniformity of illumination is 0.8; The color rendering index is more than 90 and the color reduction is high; Grid anti glare design, glare value is less than 16, no glare; Color temperature is 5000K, comfortable and soft; The illumination of the whole classroom is uniform, without stroboscopic and blue light hazards.

Huahui led eye protection classroom lamp and led eye protection blackboard lamp can be used together with Huahui lighting aiot intelligent education lighting overall solution. Through self-developed intelligent lighting products, equipped with self-developed intelligent box (such as intelligent power distribution box or intelligent air switch), intelligent full touch screen scene switch, remote control or mobile app can be used to easily switch the lighting mode that meets the needs of teaching, Realize the constant illumination of the whole classroom, one button scene control, curtain linkage, UV sterilization and other intelligent needs!
