How to choose children's eye protection lamp
Ophthalmologists analyzed the spectra of light emitted by incandescent lamps, fluorescent lamps, halogen lamps and LED lamps, and found that their spectra were similar, but they were far from sunlight. Relatively speaking, DC eye protection lamp is less harmful to eyes, but it is also more expensive. The basic working principle of eye protection lamp is to improve the low-frequency flash to high-frequency flash, which can flash thousands or even tens of thousands of times per second, and the flash speed exceeds the nerve reaction speed of human eyes. Therefore, when people study in this light, they will feel more comfortable with their eyes in a short time.
However, the electromagnetic radiation of high-frequency electricity will also increase, that is, the electromagnetic radiation of high-frequency lamps is greater than that of ordinary desk lamps, which may cause another kind of harm.
