The rejuvenation of myopia is not as simple as "wearing more glasses". The generation and damage of myopia are irreversible. Deep myopia is very easy to cause various retinopathy, resulting in serious visual effects.
Most of the reasons for the decline of students' eyesight are caused by the poor lighting natural environment of the school, especially the teenagers whose eyesight is in the period of growth and development. They are in the light natural environment that does not meet the regulations for a long time, study anxiously and bear the extreme lighting environment, and their eyesight will be affected.
The social science foundation project "scientific research on classroom physical and mental health lighting based on the utility of light microorganisms" shows that poor classroom lighting in schools directly affects the learning efficiency and visual health of children and adolescents.
In order to better prevent myopia, relevant specifications such as "implementation plan for myopia prevention and treatment of primary and secondary school students", "classroom lighting and lighting quality standards of primary and secondary schools", "design standards of primary and secondary schools" were issued. Include the following specifications:
1. The average illumination intensity on the surface of desks and chairs in the classroom shall not be less than 300lx, and the uniformity of illumination intensity shall not be less than 0.7;
2. The blackboard shall be equipped with some lighting lamps, the average illumination intensity value shall not be less than 500lx, and the uniformity of illumination intensity shall not be less than 0.8;
3. 3300k-5500k LED color temperature light source should be selected in the classroom, and the color rendering of the light source is not suitable for less than 80;
4. The uniform glare value (urg) of the classroom is not suitable to exceed 19;
5. Under the standard of maintaining the average illumination intensity value of 300lx, the current standard value of classroom lighting power shall not exceed 11W / m2, and the target shall be 9W / m2;
6. When calculating the light intensity in the lighting design scheme, the maintenance coefficient shall be 0.8.
The high-quality lighting environment in the classroom can reduce students' visual fatigue and effectively prevent myopia! 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!
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!
