It is understood that the Ministry of education conducted a survey on the myopia rate of 14532 primary and secondary school students in 9 provinces. Compared with the general test at the end of 2019, the myopia rate increased by 11.7% in this half year, including 15.2% for primary school students, 8.2% for junior middle school students and 3.8% for senior high school students.Students spend 60% or more of their time in the classroom every day. Fluorescent tubes and ordinary lamps are used in many schools. The illumination is low, substandard, dazzling, stroboscopic and color rendering index is less than 80. If you study in this environment for a long time, the human body is prone to fatigue, decreased attention, reduced learning efficiency, and eventually lead to myopia.Good or bad classroom lighting environment plays an important role in students' visual health. 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.The transformation of classroom lighting is an innovative measure under the current situation. 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"!As a promoter of campus lighting light health, Huahui lighting is the first batch of qualified units for classroom high-quality lighting environment in South China.

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!

With the high myopia rate of students, all sectors of society and government departments have paid more attention to classroom lighting in recent years. A survey shows that primary and middle school students spend about 60% of their time in the classroom every day. The experiment of NSFC project "Research on classroom health lighting based on photobiological effect" shows that school classroom lighting directly affects students' learning efficiency and visual health.Classroom lighting, as the name suggests, is used for the lighting environment in the classroom, including kindergartens, primary and secondary schools and all kinds of classrooms for teaching. The main scope of classroom lighting includes desk lighting and blackboard lighting, as well as the natural lighting and artificial lighting environment of the overall space.With the attention of relevant national policies, the transformation of classroom light environment is in full swing all over the country. However, we found that even if some classrooms were replaced with special lamps for the classroom, the lighting quality was unqualified.The transformation of classroom lighting should not be understood as "replacing old lamps with new lamps", but an overall solution to the lighting environment, including professional lighting design based on real space scenes and the needs of different people, photobiology theory, high-quality lamps and light sources, refinement of intelligent control and so on.Classroom lighting transformation should not only carefully select eye protection lamps, but also the lighting environment should meet the requirements of national standards!
