What are the provisions of the General Administration of Quality Supervision, Inspection and Quarantine on the strobe standard of children's desk lamps, and how to choose it?

At present, the national standard requires that the strobe frequency of desk lamps be higher than 3 125Hz. If it exceeds this frequency, it can be considered that this desk lamp will not cause harm to vision. The mainstream eye protection desk lamps on the market far exceed this standard, so when buying children's desk lamps, you basically don't have to pay too much attention to the flashing of the desk lamps.

On the other hand, buying things for children is not afraid of 10 thousand, just in case. So when I buy a desk lamp for my child, I always check the strobe. It is very simple to detect the stroboscopic of the desk lamp, that is, aim the camera function of the mobile phone at the light source of the desk lamp when opening the desk lamp. Under normal circumstances, a desk lamp with strongpoint can clearly see the flashing light on the camera screen, while a good quality desk lamp hardly flashes.

The method is simple but easy to use, so I ruled out many models and finally chose the L 1 desk lamp. After using it, I found that it has more than one advantage. Fire-eye crystal L 1 desk lamp has even illumination under Baidu, soft and not dazzling. The color rendering index Ra & gt97, in popular terms, means that the color reproduction is high, which is basically the same as that under natural light.

It has been used for a month now, and the child also said that his eyes are not as tired as before.
