Since 2018, comprehensive prevention and control of myopia in children and adolescents has become a concern of the whole society. Various provinces and regions have fully implemented policies such as the "Comprehensive Prevention and Control of Myopia in Children and Adolescents Implementation Plan" and the "Bright Action Plan for Myopia Prevention and Control in Children and Adolescents (2021-2025)" to promote new progress in comprehensive prevention and control of myopia in children and adolescents. Among them, as an important place for students to learn, the quality of the lighting environment in the classroom cannot be ignored.

The State Administration for Market Regulation and the National Standardization Administration Commission 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 specific parameters of classroom lighting fixtures in primary and secondary schools, the overall illuminance of classrooms and the hygienic requirements for design and installation are specified in detail:

1. Suspended grille lamps should be used, and the efficiency of the lamps should not be less than 60%.

2. The unified light value (UGR) of lamps should not exceed 19.

3. The color temperature of lamps should be 3300K~5500K, and the Color index should not be less than 80.

4. The average illumination of the classroom desktop should not be less than 300lx, and the uniformity of illumination should not be less than 0.7; The average illumination on the blackboard surface shall not be less than 500lx, and the uniformity of illumination shall not be less than 0.8.

5. The lighting fixtures are installed using suspension rods and evenly arranged in the longitudinal direction of the classroom (the long axis of the lighting fixtures is perpendicular to the blackboard). The lighting power density in the classroom should not exceed 11W/㎡, and in areas with conditions, it should be lower than 9W/㎡. The vertical distance (g) between the lamp and the desk shall not be less than 1700mm.

6. When calculating illuminance in lighting design, the maintenance coefficient should be taken as 0.8.

Primary and secondary schools should create lighting environments that meet national standards for students. 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 lighting OEMs, and OEMs choose the "Huahui Lighting" brand!

Huahui Lighting has been deeply involved in the lighting industry for 28 years. It is one of the first units in South China to reach the standard of high-quality lighting environment for classrooms. For four consecutive years, China's lighting industry has been known as the "Top Ten Educational Lighting Brands". It strictly controls the color temperature, glare, blue light, illuminance and other problems in educational lighting to avoid harmful effects of poor lighting on students' vision and health!

Huahui Lighting has designed specialized lighting fixtures for classroom lighting - LED eye protection classroom lights and LED eye protection blackboard lights, which comply with national standards and maintain an average (constant) illumination of more than 300lx for desks, with an illumination uniformity of 0.7; The blackboard maintains an average (constant) illumination of 500lx and an illumination uniformity of 0.8; The Color index is greater than 90, and the color reversibility is high; Adopting grille anti glare design, with a glare value less than 16, not dazzling; The color temperature is 5000K, comfortable and soft; The entire classroom has uniform illumination, no flickering, and no harm from blue light.

Using Huahui LED eye protection classroom lights and LED eye protection blackboard lights, it can be paired with Huahui Education Lighting AIoT intelligent education lighting overall solution. Through self-developed intelligent lighting products equipped with self-developed intelligent boxes (such as intelligent distribution boxes or intelligent air switches), intelligent full touch screen scene switches, remote control
