This article "Children's LED eye protection table lamp standards are officially announced and how to buy eye protection table lamps? 》It is compiled and published by BCTC. Please indicate the source for reprinting.

Before starting the text, let's first understand the principle and structure of the lower eye protection lamp:

The working principle of the eye protection desk lamp is to increase the low frequency flicker to the high frequency flicker. This kind of eye protection lamp uses a frequency conversion electronic ballast to increase the current frequency from 50Hz to 30-50kHz so that the human eye does not feel the flicker. The three primary color phosphors make the light soft, so as to reduce eyesight fatigue. Product test report

The eye protection desk lamp is mainly composed of two parts: a luminous source and a lamp. The light source is usually energy-saving fluorescent lamps (ie, energy-saving lamps), halogen lamps or LED lamp beads; lamps include lampshades that can prevent or reduce glare, lamp poles, bases, and drive circuits composed of electrical components. The eye protection lamp has the characteristics of instantaneous bright spot, quiet and no noise.

LED desk lamps must have entered thousands of households. Especially for teenagers who often need to read when they are growing up, the performance of the LED eye protection desk lamp and the protection of the eyes are particularly important. Data show that the myopia rate of young people in my country is increasing year by year. Among them, in addition to bad and incorrect habit of using lamps and eyes, the choice of correct lamps that can really care for the eyes is also an important factor. Tripartite Testing Laboratory

Looking at the entire LED eye protection desk lamp market, almost everyone claims that their products have eye protection functions, but in fact? Manufacturers are overly chasing profits, and I am afraid that most of them are over-charging. In addition, my country has no relevant standards for LED eye protection desk lamps in this industry before, which makes it impossible for inspection agencies and manufacturers to form industry standards.

At this time, my country's LED eye protection desk lamp group standard was released. Although it is a group standard, the group standard is also recognized in my country, and it also has the basis for specifications and testing.

Therefore, this LED eye protection table lamp standard specifies the terms and definitions, requirements, test methods, test reports, packaging, transportation, and storage of LED eye protection table lamps. It is suitable for table lamps that use LED as the light source to claim "eye protection".

The following is a standard screenshot:

Now that the relevant standards for eye protection desk lamps have come out, there will be a standard basis for enterprise manufacturing and pre/post-market spot inspections. However, many of the standard standards of testing content are not available to ordinary people, because you do not have a professional Testing equipment and tools, so even so, is it impossible to choose a good and real eye-protecting LED desk lamp? It is not true, 90% of the following methods can still choose a real eye-protecting LED desk lamp. Next, BCTC will teach you how to buy a good LED eye-protecting desk lamp. Waterproof detection of lamps and lanterns

1. Preferentially choose products with CCC certification marks that have been certified by testing and certification agencies

2. Has it passed the international IEEE PAR 1789 non-stroboscopic hazard eye protection certification?

3. Choose the eye protection desk lamp tested for blue light hazard as RG0, you can pay attention to the blue light hazard level of the retina on the desk lamp, and you can also see whether it has passed the EU blue light hazard-free IEC/EN 62778 certification and IEC/EN 62471 certification

4. Choose a table lamp with national AA level (brightness>600LM) nominal illuminance. Especially if you need to work under a desk lamp for a long time, it is recommended to choose a desk lamp with a high illuminance level to protect your eyesight.

5. Choose a table lamp with a high color rendering index. When parents buy a table lamp for their children, the color rendering index should generally be greater than 90. If you want to paint under the table lamp, which requires high color, it is recommended to buy color rendering. Products with an index greater than 90. Authoritative testing

6. When using the eye protection desk lamp, adjust the brightness to 300 lux, but the 300 lux brightness cannot be directly judged by the eyes. It is necessary to choose the LED eye protection desk lamp with automatic dimming function

7. When using the eye protection desk lamp, turn on other lamps in the room at the same time to create a comfortable lighting space environment and avoid an environment with too strong contrast between light and dark.
