In order to comprehensively improve the lighting environment of ordinary classrooms in primary and secondary schools and effectively reduce the incidence of myopia among students, in recent years, many regions across the country have accelerated the implementation of the project to improve the health lighting of ordinary classrooms in primary and secondary schools.

A survey shows that about 60% of primary and secondary school students in China spend time in the classroom every day. In the experiment of the National Natural Science Foundation of China's "Research on Classroom Health Lighting Based on Photobiological Effects", it is more scientific to show that school classroom lighting will directly affect students' learning efficiency and vision health.

The State Administration of Market Supervision and Administration and the National Standardization Administration approved and issued the Hygienic Requirements for the Design and Installation of Lighting in Ordinary Classrooms of Primary and Secondary Schools (GB/T36876-2018). In this new standard, the illumination of desktop and blackboard surfaces and the hygienic requirements for design and installation of ordinary classrooms of primary and secondary schools are specified in detail:

1. Hygienic requirements for illumination of classroom desktop and blackboard

Maintain the average illuminance not less than 300lx and the illuminance uniformity not less than 0.7; The average illumination of the blackboard surface shall not be less than 500lx, and the illumination uniformity shall not be less than 0.8.

2. Hygienic requirements for design and installation of blackboard lighting

1) Special blackboard lamps with asymmetrical light intensity distribution characteristics shall be used, and the lamp efficiency shall not be less than 75%; The light source is the same as the classroom lighting requirements.

2) The suspender installation method is adopted, and the lamps are installed parallel to the blackboard; The parallel distance between the lamp and the blackboard is d=700mm-1000mm, and the horizontal and vertical distance from the upper edge of the blackboard is h=100mm - 200mm. The blackboard lamp should be adjusted to avoid direct glare to teachers.

The completion of lighting transformation in the classroom in line with national standards can protect students' vision health. How can the classroom lighting be transformed to meet 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 lighting OEMs and licensors choose the "Huahui Lighting" brand!

As a health promoter of campus lighting, China Lighting has been deeply involved in the lighting industry for 27 years. It is one of the first units to reach the standard of high-quality lighting environment in classrooms in South China, and also one of the "top ten educational lighting brands" in China's lighting industry in 2021. It strictly controls the color temperature, glare, blue light, illuminance and other problems in educational lighting, so as to avoid harmful effects of poor lighting on 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 that the average (constant) illuminance of desks is more than 300lx, and the illuminance uniformity is 0.7; The average (constant) illumination of the blackboard is 500lx, and the illumination uniformity is 0.8; The color rendering index is greater than 90, and the color reversibility is high; The grid anti glare design is adopted, and the glare value is less than 16 without 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 lights and LED eye protection blackboard lights can be matched with the overall solution of Huahui Education Lighting AIoT intelligent education lighting. Through the self-developed intelligent lighting products, the self-developed smart boxes (such as intelligent distribution boxes or intelligent air switches) can be loaded, and the intelligent full touch screen scene switch, remote controller or mobile phone APP can be used to easily switch the lighting mode that meets the teaching needs, so as to achieve constant illumination, one button scene control Intelligent demands such as curtain linkage and ultraviolet sterilization!
