According to the survey of 14532 people in 9 provinces conducted by the Ministry of education, compared with the end of 2019, the myopia rate of students has increased by 11.7% in the first half of 2020, including 15.2% for primary school students, 8.2% for junior middle school students and 3.8% for senior high school students. Experts believe that the impact of classroom lighting environment on children's vision can not be ignored.
Important departments of the Ministry of Education issued the notice on the implementation plan for comprehensive prevention and control of myopia among children and adolescents. With the attention of the state and schools, we continue to invest in the classroom lighting market to create a high-quality lighting environment for students.
What is the high-quality lighting environment in the classroom? The high-quality lighting environment in the classroom is first natural lighting, supplemented by eye protection lamps in the classroom, so as to protect visual health and other elements. The parameters of the high-quality lighting environment in the classroom include: the average illuminance maintained on the desk and blackboard, illuminance uniformity, color rendering index (RA), special color rendering index (R9), light source color temperature, unified glare value (UGR), blue light hazard, etc.
How can classroom lights meet the lighting environment of the classroom? First of all, we must pass the "rules for the implementation of compulsory product certification" of "CCC" and the "rules for energy saving certification of lighting products in primary and secondary schools and kindergartens" of "CQC". Secondly, it is necessary to meet the hygienic standards for lighting and lighting in primary and secondary school classrooms and the hygienic requirements for myopia prevention and control of school supplies for children and adolescents currently being formulated by the National Health Commission and other relevant departments.
Eye protection classroom lamps should be selected for classroom lamps. 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 "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 students' 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!
