Although eye-friendly table lamps have become a popular product in the field of table lamps, they are also a must-buy for many parents when choosing school supplies. However, there are still many people around us who don't know what an eye-protecting desk lamp is. As a practitioner in the field of lamps and lanterns, I have always been asked by friends: what is an eye-protecting table lamp? What is the difference between it and the eye protection device on the Internet? How to choose a table lamp for children? These problems also show that there are still many people who do not know much about eye protection desk lamps. Therefore, as a practitioner, I think it is necessary to give you some knowledge about eye protection table lamps.
1. What is an eye-protecting table lamp? What's the use?
1. What is an eye protection table lamp?
Judging from the name alone, the eye-protecting table lamp is a table lamp. Strictly speaking, the eye-protecting table lamp is a "propaganda concept", and there is no separate standard for "eye-protecting table lamp" in the relevant national product standards. In the national relevant product identification, the eye-protecting desk lamp is classified into the category of "reading and writing desk lamp". From this classification, it can be seen that the main customer group for the eye protection table lamp is students. Therefore, we can understand the eye-protecting desk lamp as a lighting desk lamp that is more suitable for students to read and write homework.
It is also a desk lamp, why is the eye-protecting table lamp more suitable for students' reading and writing homework? Nowadays, with the development of health medicine, people have gradually found that the quality of light is an important factor affecting the health of human eyes, so more and more parents have begun to pay attention to the quality of light when their children read and write. It is precisely this demand that many lighting manufacturers have begun to develop eye-protecting table lamps.
Compared with the traditional LED lighting desk lamp, the biggest advantage of the eye-protecting desk lamp is that its various index parameters are in line with the national standard, that is, the provisions in the "GB/T9473-2022 Performance Requirements for Reading and Writing Work Desk Lamp". This document specifies the main technical indicators of the reading and writing desk lamp. For example, illuminance and illuminance uniformity. The "Requirements" stipulate that the minimum horizontal illumination of the central area (30cm*50cm rectangular area) should not be less than 500lx; The illumination uniformity should not be greater than 3. It is precisely because of such specific and strict standards that eye-protecting table lamps can play a role in protecting eye health.
2. What is the function of the eye protection table lamp?
According to my personal observation and understanding, the biggest use of the eye-protecting table lamp is "not hurting the eyes" and "eye-catching".
Let's start with "don't hurt your eyes". As we all know, there are two common hazards in LED lighting fixtures: blue light and strobe. At the same time, for teenagers and children, if they study in an environment with poor light quality for a long time, such as too bright light and too high color temperature, their eyes are easily fatigued and then develop myopia. The emergence of the eye-protecting table lamp can be said to solve this problem to a certain extent.
First of all, at present, all eye-protecting table lamps that meet national standards can control their blue light hazards at the level of RG0, that is, there is no blue light hazard. The strobe can be controlled at a level that is free of the hazards of video flicker. Therefore, by studying under the eye protection lamp, the eye health of young students is more guaranteed.
Secondly, the technical parameters of the eye-protecting table lamp are in line with national standards. For example, the "Requirements" recommends that reading and writing activities should be carried out at a color temperature of 4000K. At present, many eye-friendly table lamps are designed with a constant 4000K color temperature to avoid the adverse effects of too high or too low color temperature on young students. Of course, in terms of illumination and uniformity, color rendering level, etc., the eye-protecting table lamp can also be better than the national standard.
Finally, some eye-protecting table lamps truly achieve the eye-protection function by applying red light eye protection technology. When it comes to eye protection, the first thing that comes to mind for many consumers is the red light eye protection device. The realization of the eye protection function of the eye protection desk lamp is similar to the principle of the eye care device, which is to emit beneficial red light through the product to stimulate the mitochondria of the retinal cells of the eye, so as to release energy to promote the metabolic repair of retinal cells and relieve eye fatigue. In addition, some medical studies have found that irradiating the eyes with red light for 3 minutes a day can effectively prevent the occurrence of myopia.
