The secret behind the seemingly good LED lamp teaches you the method of quickly identifying the bad LED lamp
Most parents think that using LED lamps is more energy-saving and environmentally friendly. More importantly, the lighting effect is much higher than that of ordinary incandescent lamps, which is conducive to protecting children’s eyes.
In fact, some LED lights are so stroboscopic that studying under them for a long time can lead to visual fatigue, headache and even photosensitive epilepsy, resulting in decreased vision and inattention problems. All the harm to children’s health is of no benefit!
There is a big difference between different LED flash lamps
Simply put, stroboflash means that when you look at the screen of one device and at the same time look at the screen of another device, the screen of another device will have a bright line from the bottom of the screen to the top and then back from the bottom. It continues, giving us the impression that the image is flashing.
The lower the flash, the less damage to the eyes. However, absolute stroboflash is practically impossible. The strobe of qualified products required by Chinese industry standards is 3,125 Hz.
