The classroom is the main place for students' activities in school. Classroom lighting directly affects students' learning efficiency and visual health. But at present, the lighting environment quality of most primary and secondary schools in China has not reached the standard requirements. What are the serious hazards of unreasonable installation of classroom lights?
When the color temperature of classroom lamps does not meet the national standard, it is also harmful to the eyesight health. When the color temperature is too low and the light turns yellow, it will make people feel sleepy and difficult to concentrate; On the contrary, when the color temperature is too high (> 6000K), the light will be too white, easy to stimulate the eyes, will increase people's anxiety, damage the eyes. In addition, the relevant experiments also confirmed that the visual environment of students was the best under the color temperature of 3300K to 5500k.
Most of the primary and secondary schools in China still use lamps directly exposed to the light source. Light directly into the eyes, produce serious glare, easy to cause visual fatigue, cause myopia, distract students' attention, thus reducing learning efficiency. At present, the color index of most fluorescent lamps used in the classroom is only about 70, the color rendering is poor, and the color distortion is serious. With the passage of time, it will cause color blindness, color weakness and other vision problems, affecting the normal development of students' vision.
The stroboscopic of ordinary non stroboscopic fluorescent lamp is due to the use of alternating current in the fluorescent lamp. When switching the current, the flicker is not easy to detect for a short time. The stroboscopic effect of light causes the ciliary muscles to contract and relax to adapt to the environment. Long term strenuous exercise can cause ciliary muscle fatigue and sore eyes.
In the experiment of "Research on classroom healthy lighting based on photobiological effect", it shows that the poor classroom lighting in school directly affects the learning efficiency and visual health of children and adolescents. Lighting comes first in education. A high-quality classroom lighting environment can provide students with comfortable eye care lighting quality, reduce visual fatigue, and effectively prevent myopia!
Recommend 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.) to choose "Huahui lighting" brand!
