In view of the phenomenon of myopia among primary and secondary school students, the Ministry of education investigated the visual changes of primary, middle and high school students in 9 provinces (autonomous regions and cities) during the epidemic, and the results were "very optimistic". Compared with the data at the end of 2019, the survey conducted in June 2020 showed that the myopia rate of primary and secondary school students increased by 11.7% in this half year.

Relevant personnel conducted data analysis on the increasingly prominent problem of students' myopia. Among them, classroom lighting is one of the causes of myopia. Therefore, it is suggested that special eye protection lamps should be used in primary and secondary school classrooms.

The necessity of using special eye protection lamps for classroom lighting. (1) The problem of myopia among primary and middle school students is becoming more and more serious. According to the survey of the Ministry of education and the health and Family Planning Commission, among the nearly 600 million myopia patients in China, teenagers are the "hardest hit area" of myopia, and the myopia rate is on the rise. (2) Lighting conditions lag. In the investigation, it is found that ordinary fluorescent lamps are still used in some classroom lighting, resulting in the average illuminance of the classroom below 200lx. These lights have a series of unhealthy factors affecting students' vision, such as low illuminance, blue light, stroboscopic, blue light hazards and so on.

Whether it is new or old classroom reconstruction, the classroom lighting should meet the requirements of 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!

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 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!
