In August 2018, according to the decision-making and deployment of the Party Central Committee and the State Council, the Ministry of education took the lead in implementing the implementation plan for comprehensive prevention and control of myopia among children and adolescents, and has been actively promoting the comprehensive prevention and control of myopia among children and adolescents.
On the decision-making and deployment of myopia prevention and control, at the third meeting of the national joint conference mechanism on comprehensive prevention and control of children and adolescents' myopia, the myopia prevention and control linkage pattern of "government led, department coordinated, school and medical institutions implemented, and social participation" was established. Outdoor activities and physical exercise were increased, students' academic burden was gradually reduced, and the publicity and education of vision health knowledge was deepened Effective measures such as improving the lighting conditions of schools and families, and insisting on standardized eye exercises were gradually implemented.
Studies have shown that learning environment is closely related to children's visual health. Reading, writing and learning should be carried out in a well lit environment. Long time in the substandard classroom lighting environment, will make them produce eye fatigue, resulting in myopia.
The State Administration of market supervision and administration and the National Standardization Administration approved and issued the hygienic requirements for lighting design and installation of ordinary classrooms in primary and secondary schools (GB / t36876-2018). In this new standard, the illumination of tabletop and blackboard surface and hygienic requirements for design and installation of ordinary classrooms in primary and secondary schools are specified in detail
1) Hygienic requirements for illumination of classroom tabletop and blackboard. Maintain the average illumination not less than 300lx and the uniformity of illumination not less than 0.7; The average illuminance of the blackboard surface shall not be less than 500lx, and the illuminance uniformity shall not be less than 0.8.
2) The design and installation of classroom lighting should meet the hygienic requirements. Hanging grid lamps should be used, and the efficiency of lamps should not be less than 60%; UGR should not be more than 19; The color temperature should be 3300k-5500k and the color rendering index should not be less than 80.
3) The suspender installation method should be adopted, and the classroom should be evenly arranged in the longitudinal direction (the long axis of the lamps is perpendicular to the blackboard). The power density of classroom lighting should not be higher than 11W / m2, and it should be lower than 9W / m2 in conditional areas. The vertical distance (g) between the lamp and the desk shall not be less than 1700mm.
Classroom lighting eye protection lamps should not only be carefully selected, but also meet the national standards! 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" brand!

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!
