Misunderstanding, a warm color illumination is beneficial to learn
Unlike the general understanding, warm-light sources are not good for students to read or write because of their low color temperature. The high color temperature (cold light source) of 5000k and 6500k is more popular among students, and it is more suitable for visual tasks such as reading and writing. In the case of meeting the illuminance of the current classroom standards, the high color temperature is more conducive to delaying the visual fatigue of primary and secondary school students and improving the learning efficiency compared with the low color temperature. This is consistent with the results of foreign research, and is used in the classrooms of primary and secondary schools. The current status of fluorescent lamps with high color temperatures is also consistent.
In addition, in the environment where the illumination level is greater than 500lx, the visual work is more efficient, and the visual experience is better, which is more conducive to students' reading and writing. Therefore, experts suggest that parents should pay attention to the use of high color temperature light source (cold light source) learning table lamp instead of warm color light source when setting up the home light environment.
Misunderstanding 2, prominent table top without background light
Often we focus on concentrating lighting on the work surface while ignoring the setting of ambient lighting. Through experimental research, it is found that for the learning environment where the table lamp is used for key lighting, the ambient lighting should be fully considered and should not be too dark. When setting up the light environment for primary and secondary school students, it is unscientific to open the design of the table lamp without ambient lighting, which is more likely to lead to increased visual fatigue, thus affecting their vision health. Especially when performing visual tasks involving the movement of the eyeball back and forth, such as copying and using a computer, it is necessary to move between the screen and the keyboard, and the environment must not be too dark. Otherwise, the eyes need to be adjusted frequently to adapt to light and dark changes, which will lead to eye discomfort and reduced work efficiency, which will increase visual fatigue after a long time. In addition, experts suggest that watching TV or playing computer also requires a certain amount of background light, not in a dark environment.
