At present, the myopia rate of primary and secondary school students remains high. More and more people advocate paying attention to the improvement of students' eyesight and classroom health lighting, especially students' parents and classrooms. The education industry has also issued relevant standards. What lamps are generally used for classroom lighting to meet the national standards?

Classroom lamps meeting national standards shall have six standards: excellent illumination, no glare, high color rendering index, no light stroboscopic hazard, moderate color temperature and no blue light hazard; The acceptance of educational lighting is also to detect these six standards.

The State Administration of market supervision and the State 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 specific parameters of classroom lighting lamps, the overall illuminance of classrooms and the hygienic requirements for design and installation of primary and secondary schools are specified in detail:

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

2. The uniform light value (UGR) of lamps shall not be greater than 19, and the calculation method of uniform glare value (UGR) shall be implemented according to cie117.

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

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

5. The lamps are installed by suspenders and evenly arranged according to the longitudinal direction of the classroom (the long axis of the lamps is perpendicular to the blackboard). The lighting power density of the classroom shall not be higher than 11W / ㎡, and it should be lower than 9W / ㎡ in conditional areas. The vertical distance (g) from the lamp to the desk shall not be less than 1700mm.

6. When calculating illuminance in lighting design, its maintenance coefficient shall be 0.8.

Therefore, educational lighting lamps should be carefully selected for classroom lighting. 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 the brand of "Huahui lighting" to effectively prevent myopia!

As a promoter of campus lighting light health, Huahui lighting is the first batch of qualified units for high-quality lighting environment in classrooms in South China. It strictly controls the color temperature, glare, blue light, illumination and other problems in educational lighting to avoid the harm of bad lighting to teenagers' visual health!

Relying on the unremitting innovation of hardware and software in the education lighting industry, Huahui lighting has won the "top ten education lighting brands" and "top ten intelligent application brands" in 2019, and once again won the "top ten education lighting brands" in China's lighting industry in 2020!

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!
