Nowadays, there are more and more myopia in primary school, junior middle school and senior high school, for many reasons. On the one hand, students have to spend more time reading and doing homework because of the high school learning pressure and many tasks; On the other hand, it is easy to be ignored: classroom lighting!
According to statistics, about 60% of each student's time is spent in the classroom. Some studies have found that excessive use of electronic products and poor classroom lighting environment are the main reasons for the decline of students' vision. As a necessary lighting source for school classrooms, what national standards should classroom lighting meet?
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, overall illumination and hygienic requirements for design and installation of lamps in 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 shall be installed with 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 lamps to the desk shall not be less than 1700mm.
6. When calculating illuminance in lighting design, its maintenance coefficient shall be 0.8.
Classroom lighting transformation is an innovative measure under the current myopia prevention and control. 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 lamp OEM and OEM choose "Huahui lighting" eye protection classroom lamps!
As a promoter of Campus Lighting health, Huahui lighting has been deeply engaged in the lighting industry for 26 years. It is the first batch of qualified units for classroom high-quality lighting environment in South China. It is also the "top ten educational lighting brands" in China's lighting industry in 2021. 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 led eye protection classroom lamp and led eye protection blackboard lamp, which are specially used for classroom lighting, In line with the national standard, the desk maintains an average (constant) illuminance of more than 300lx, and the illuminance uniformity is 0.7; the blackboard maintains an average (constant) illuminance of 500lx, and the illuminance 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 illuminance 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 combined with Huahui education lighting aiot intelligent education lighting overall solution, Through the self-developed intelligent lighting products, equipped with the self-developed intelligent box (such as intelligent distribution box or intelligent air switch), the intelligent full touch screen scene switch, remote controller or mobile phone app can easily switch the lighting mode required for teaching, so as to realize the intelligent needs of the whole classroom, such as constant illumination, one button scene control, curtain linkage, ultraviolet sterilization and so on!
