What are the huge hazards of "fluorescent lamps" used in classroom lamps?
1. The "stroboscopic effect" of classroom lamps seriously endangers students' eyes
The lamps used in classrooms in most schools in China are directly installed with exposed fluorescent tubes, and the light of these fluorescent lamps will directly stimulate the eyes of students, causing glare, which greatly distracts students from studying in the classroom and makes students' eyes The learning efficiency is seriously reduced.
더욱이, 이러한 보호되지 않은 형광등에 장시간 교실에 노출되면 교실에 있는 사람들의 비디오 피로를 유발하고, 근시와 같은 안과 질환을 유발하기 매우 쉽습니다.
Magnetic ballast is a component installed in most fluorescent lamps, which will cause serious light stroboscopic effect of fluorescent lamps. In order to adapt to the change of the frequency of the light, the human eye will continuously adjust itself. The long-term self-regulation of the optic nerve is equivalent to the eyes "doing exercise" all the time. After a period of time, the eyes will feel extremely tired. .
학생들은 학교 교실에서 칠판과 교과서를 마주하며 대부분의 시간을 보냅니다. 눈을 오랫동안 사용하면 확실히 눈이 손상됩니다.
2. The "color rendering index is too low" of classroom lamps
일반 교실 램프의 또 다른 단점은 연색 지수가 너무 낮다는 것입니다!
The color rendering index of fluorescent lamps in most school classrooms is generally around 70 (national standard: the color rendering index of the light source should not be less than 80). Such a low color rendering index will cause visual color distortion and affect students' learning. Especially in the professional classrooms that are sensitive to color requirements such as art, chemistry, and handicraft, a too low color rendering index will affect the students' eyes to recognize the color of the object, so that the object cannot show its true color. If this situation continues , it is easy to cause serious vision problems and eye diseases such as color blindness and color weakness.
3. The terrible "blue light hazard" of classroom lamps:
China's domestic classrooms basically use high color temperature (6500K) fluorescent tubes, and the national standard requires classrooms to use a light source with a color temperature of 3300-5500K. The high color temperature is because the light color is too white, it is easy to cause students to be excited and easily fatigued.
At the same time, domestic classroom lighting basically has very terrible "blue light hazard" and "ultraviolet radiation". Blue light can cause irreversible and irreparable damage to the retina of students' eyes.
교실 램프의 위험 요소가 너무 많기 때문에 근시가 있는 중국 학생의 비율이 끔찍하게 높은 것은 놀라운 일이 아닙니다.
지금 캠퍼스에 안경을 쓰지 않는 학생이 거의 없다는 사실이 매우 안타깝습니다.
