UVLED Since it has so many benefits in terms of function, it must be harmful to the human body. Specifically, uv led What are the harmful effects on the human body? Let's discuss it together. First of all, UVLED is a purple light source LED, so under normal circumstances, the impact of purple LED on the human body is actually negligible. The UV in UVLED means purple light. Although general UVLED has no effect on the human body, you still need to take precautions. Just like facing a computer screen, it is exposed to ultraviolet (violet light). The UVLED we often talk about is not this type of ultraviolet light.
UVLED used for uvled sterilization is harmful to our human body. The principle of sterilization is that ultraviolet rays in this band can destroy and kill genetic material, causing bacterial cell death. Some of the ultraviolet rays in sunlight also have a sterilizing effect. This is the principle. These injuries can be seen with the eyes, but there are also some hidden dangers, so you still need to take precautions. The penetrating power of ultraviolet rays is generally very small, and a layer of protective clothing can provide protection. Of course, your eyes are the most important. Even if you are well protected, don’t look directly at them. UVLED light source , to avoid irreversible damage.
The UVLED we call is for industrial use UVLED curing lamp . Some industrial UVLEDs are harmful to the human body, but just take good protection. There are many UVLED bands used in industry, generally around 250nm for sterilization and disinfection. ； 365nm, 375nm, 385nm and 395nm for curing light-curing resin UVLED curing lamp。
For the UVLED band used for curing, there is still some damage. The smaller the waveband, the greater the damage, and the longer the waveband, the smaller the damage. After the wavelength exceeds 400nm, it is the visible light that our eyes see. The harm of visible light to the human body has never been seen so far. UVLED at 395nm is basically harmless to the human body.
UVLEDs are harmful, but not all are harmful. Just like the bactericidal effect of ultraviolet light, it is beneficial when used properly, but harmful when used improperly.
