In order to prevent students' myopia, the prevention and control of myopia has gradually been put on the important agenda. From the optical point of view, improving the lighting environment is an effective method to prevent and control juvenile myopia. In this regard, Huahui education lighting believes that the key to preventing myopia lies in classroom lighting.
Classroom is the place where students spend the longest time in a day. The importance of high-quality classroom light environment for teenagers' growth and learning is self-evident. However, the lighting environment of most classrooms now seriously does not meet the standards. There are many problems, such as low illumination, uniformity, color rendering index, stroboscopic, glare and so on, which are lower than the national standards.
For the existing problems, Huahui education lighting puts forward the "9 + 3" professional classroom lighting solution. This means that the standard classroom is equipped with 9 eye protection classroom lights and 3 eye protection blackboard lights, which can meet the national requirements for classroom lighting. Because classroom lighting is related to the physical and mental health of children and adolescents, especially reducing the myopia rate of adolescents, classroom lighting needs to pay more attention to light quality and adopt comfortable classroom eye protection lamps.
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.
3. The color temperature 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.
Select the classroom eye protection lamp that meets the national cellar standard. 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"!
As a promoter of Campus Lighting health, Huahui lighting is the first batch of qualified units for high-quality lighting environment in classrooms in South China. It is also the "top ten educational lighting brands" in China's lighting industry in 2020. It strictly controls the color temperature, glare, blue light, illumination and other problems in educational lighting to avoid the harm of bad lighting to children's 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. 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!
