From September to December 2020, China carried out a comprehensive myopia survey and screened 2.477 million students. According to the report, the results of this survey show that the overall myopia rate of children and adolescents in China is 52.7%.

The problem of myopia and younger age is prominent, which seriously affects students' learning and daily life. The main causes of children's myopia are genetic factors, bad learning habits, playing computer games or mobile phones for a long time, etc. in addition, in fact, campus lighting, desks and chairs and other teaching environments are also related to the changes of children's vision during their growth.

Poor lighting and lighting in the classroom can easily lead to eye fatigue and the decline of students' eyesight. It is also excessive eye fatigue, which is an important factor leading to myopia. Therefore, the school should provide students with eye protection and healthy classroom lighting environment, select lamps that meet the classroom lighting standards, and transform the poor lighting environment.

At present, the current situation of lamps used in some schools is that most classroom lamps use simple open double ended fluorescent lamp bracket lamps, while blackboard lighting has no special lamps. Double ended fluorescent lamp bracket lamps are also installed in front of the blackboard as blackboard lamps, and even there is no blackboard lighting in some areas. The light source of the open double ended fluorescent lamp bracket lamp is directly exposed to the outside of the lamp without any anti glare measures, which will have a great glare impact on the students sitting in the back row.

The most important measure to prevent students' myopia is to improve the classroom lighting environment! 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, etc.) 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 students' 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!
