The ** eye protection table lamp on the market is from hundreds to thousands of yuan, if it is economically allowed, of course, the more expensive it may be, the better, more people still need cost-effective eye protection table lamp, this is also my original intention to write this article, and in order to avoid pitfalls for everyone, as an evaluation blogger, based on my personal purchase experience, I will give you a tutorial on how to buy eye protection table lamps, I hope to help you.
The function of the eye protection table lamp is to relieve eye fatigue and effectively protect the eyes, but it should also be noted that it can be used correctly in order to have an effect, and the eye habits have a great relationship with the environment.
1. What factors should I pay attention to when buying an eye-protecting table lamp?
1) Illuminance
The standard of measuring the lighting ability of the light source, the brightness is too dark or too bright will be harmful to the eyes, generally the illuminance is in line with the illuminance standard at 300-500lux, the country has a clear standard for reading and writing desk lamps, which are mainly divided into national A level and national AA level, the main difference is that the brightness is different.
National A-level standard:The radius from the center of the table lamp is 30cm in the 120° sector area, and its illumination is more than 300lux.
The 120° sector area with a radius of 50cm from the center of the table lamp is more than 150lux.
National AA standard:The radius from the center of the table lamp is 30cm in the 120° sector area, and its illumination is more than 500lux.
The radius from the center of the table lamp is 50cm in the 120° sector area, and its illumination is more than 300lux:
Although Class A meets the national illumination standard, from the perspective of eye health, it is recommended to choose Class AA standard table lamp.
Uniformity is simply the contrast between the center illumination and the edge illumination, the closer the uniformity of the desk lamp is to 1, the more uniform the light, the requirement in the "Reading and Writing Performance Desk Lamp Operation Requirements" is that the uniformity can be <3, but the uniformity is better to reach about 2.
2) Color rendering index
Refers to the presentation of the natural primary color of the object by the light source, that is, the ability to give people a visual feeling, the closer the color rendering index is to 100, the better the new Arthur nature of the light source, indicating the stronger the color restoration ability of the object, the standard mileage of the reading and writing desk lamp requires more than ra80, but the color rendering index is too low will affect the recognition of color, it is recommended to choose a high color rendering value of ra95 or more.
3) Color temperature
It represents the color performance of the light color of the light source, which is generally divided into three types of cold and warm colors.
Low color temperature(<3000K) warm white tone, long-term lighting is easy to get sleepy, generally used as a night light.
Neutral color temperature(3000k-5000k) daylight white tones, giving a sober but warm feeling, will not be sleepy, nor dazzling.
High color temperature(>5000K) cool white tone, giving people a calm feeling, often using it will make you feel eye fatigue, there is a risk of myopia.
Therefore, as the color temperature in 4000K is the most suitable reading, when choosing a desk lamp, you can choose the one with adjustable color temperature or the color temperature at 4000K is the best.
4) Blu-ray
Refers to the short-wave blue light at 400nm-5000nm visible light, studies have shown that long-term exposure to blue light will cause certain chronic damage to the retina, but not all blue light is harmful.
Blue light between 480-500nm is beneficial blue light, which has the effect of regulating biological rhythms, helping with sleep, memory, etc.
International lighting will retinal blue light according to the degree of danger, divided into (no hazard level) RG0, (low risk level) RG1, (medium risk) RG2, (high risk) RG3 these four levels, reading and writing the use of desk lamp retinal hazard level standards can not exceed rg0, most of the current desk lamp can do no blue light rg0
5) Strobe
That is, the luminous flux of the electric light source fluctuates at a certain frequency, and the strobe frequency is relatively low, which will cause eye fatigue, and when the strobe is high to a certain extent, the human eye can not feel the light flickering, so we are not pursuing "no strobe", it should be "no strobe", to understand that it is impossible to do truly no flicker, teach you a method that can be tested at home, use a mobile phone to turn on the camera against the light, whether there is a fluctuation.
Finally, to summarize the five factor criteria, you can start if you meet the following criteria:
Illuminance and uniformity: national AA level, the closer the uniformity is to 1, the better.
Color rendering index: Ra95 or above.
Color temperature: 4000K neutral color temperature is best.
Blue light: non-hazardous RG0
Strobe: No ** flash.
Second, it is worth starting with seven popular eye-protecting table lamp recommendations
