More and more primary and middle school students wear myopia glasses in schools, and they are younger. Myopia not only affects normal study, but also affects further education and employment in the future. As we all know, the main causes of students' myopia are genetic factors and bad habits, such as close reading, touching electronic products for a long time, playing computer games or playing mobile phones... In fact, it is often easy to be ignored: classroom lighting.
Chinese students spend 60% of their time in the classroom every day, so the good or bad classroom lighting directly affects students' visual acuity. In the hygienic code for daylighting and lighting of classrooms in primary and secondary schools (gb7793-2010), the hygienic requirements for daylighting and lighting of classrooms are clearly specified:
1) Daylighting. The classroom should use north-south two-sided daylighting. For the classroom with one-sided daylighting, the light should enter from the left side of the student seat to avoid the shadow of the hand hindering the line of sight when writing. When the south is the corridor and the north is the classroom, the North window should be the primary daylighting surface; In order to prevent direct glare from windows, the classroom shall be equipped with window cloth to prevent sunlight from directly entering the classroom.
2) Lighting. The classroom should be equipped with LED eye protection classroom lights, which have six characteristics: uniform brightness, no stroboscopic, anti glare, no blue light harm, high color rendering index and suitable color temperature; The classroom blackboard shall be equipped with LED eye protection blackboard lamps with uniform illumination of no less than 500lx. Generally, 2-3 classroom blackboard lamps shall be arranged parallel to the blackboard. The uniform illumination value on the classroom table should not be less than 300lx. Generally, 9 eye protection lamps are required in the classroom; In order to reduce the direct glare caused by the lighting source, the classroom should not use naked lamps for lighting. All lamps should be equipped with eye protection lamps with lampshades and grids.
Classroom lighting has become a new battlefield for 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, etc.) choose the "Huahui lighting" brand!

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!
