Are student-specific eye protection desk lamps good for the eyes?
In modern life, when we buy table lamps, we like to choose some multi-functional or eye-catching ones. The focus is always on whether the appearance is special, cute, or whether it is smart, and whether the light is bright enough. In fact, the editor of Shenzhen eye protection table lamp manufacturer also thought so before contacting the table lamp industry. But this is just a mentality that everyone has, it can be good-looking and practical, no problem!
However, most people don't find that the brightness of some desk lamps for students is brighter than that of ordinary lamps. Many times, when we look directly at the desk lamp, we will feel uncomfortable and dazzling in our eyes. This is a type of desk lamp (LED eye protection desk lamp). Looking directly at the LED light source will cause some damage to the eyes, because the LED light is a point light source, although the damage is there, but it is also much less than the damage caused by the ordinary light.
About the current color temperature of the LED desk lamp is too high, close to the color temperature of sunlight at noon, so it is not very comfortable to look at, and the beam angle of the LED desk lamp is too small, the light is too concentrated, if the students are not careful to look directly, it will cause eye damage It's irreparable damage, and to be honest, it's too expensive. If you have to buy it, buy one with a color temperature not higher than 4000K, otherwise students will see it and it will cause myopia.
Experts say that LEDs are not suitable for desk lamps. In recent years, the Institute of Electric Light Sources of Fudan University has done a lot of tests on the domestic reading lamp market, and found that there is a lot of blue light from LEDs, which is not good for eyesight. In addition to the blue light problem, the common problem of LED desk lamp products in the past few years is that the luminous flux is insufficient and the light is relatively dim; in addition, in terms of color rendering, the color will be distorted when looking at things under the LED desk lamp. At the same time, only a small part can be illuminated, which is called inappropriate light distribution. In addition, the light-emitting point of the LED desk lamp is relatively bright, and if you look directly at it, it will feel very dazzling, and the eyes will feel very uncomfortable. At present, the country does not have a unified standard for LED desk lamps, and some very inferior LED desk lamps are actually not beneficial to the eyes. Therefore, in addition to individual products with particularly good quality, they cannot play a very good role in eye protection.
