My child uses the compound light DC eye protection lamp you mentioned, but it is bought in the mall, which is a bit expensive. But it is definitely worth using, and the effect is much better than those so-called big factory lights. Children don't feel tired after watching for hours, and there is no stroboscopic and radiation. The lamp has the national patent number ZL03 128820.0 (stroboscopic energy-saving DC fluorescent lamp). I saw you talking today, so I went to have a look.
LED is a new generation of light source? On the Dream Tower, the LED on the right is very bad. The LED is a light-emitting diode display screen, which is a general outdoor large-scale advertising display screen. You can see those light boxes and those large monitors with or without flashing outside. The most intuitive thing is to watch these displays on TV. If it is simplified to eye protection lamp, does it flash quickly? Does it mean that if you can't see it, you won't flash? Does it mean no radiation?
To tell the truth, my friend, foreign desk lamps are simply not as good as composite DC eye protection desk lamps. I have been abroad myself, and there are no good eye protection lamps abroad. I don't know why, but I guess they are worried about something else. There are other domestic brands of garbage that are not DC, not to mention. You might as well buy it directly with fluorescent lights.
I recommend you buy a multi-beam DC eye protection lamp, which can be said to be the best eye protection lamp at present.
