UVC LED yorug'ligi (254/365nm) inson tanasiga qanday zarar etkazadi va uni qanday himoya qilish kerak?
Ultrabinafsha nurlarning inson tanasiga zararini yanada intuitiv tushunish uchun, avvalo, ultrabinafsha nurlar (UV) haqidagi asosiy bilimlarni tanishtirishga ijozat bering. Ultraviyole (UV) uchta aka-ukadan iborat: UVA/UVB/UVC.
Har bir guruh o'ziga xos xususiyatga ega. Bu erda faqat UVA va UVC amalga oshiriladi; 254nm UVC diapazoniga, 365nm esa UVA diapazoniga tegishli. Ultraviyole nurlar qisqa to'lqin uzunligiga ega, ammo yuqori energiyaga ega. Inson tanasining zarari ikkalasidan farq qiladi, shuning uchun men ular haqida alohida gapiraman.
The comparison chart of ultraviolet sterilization ability of different wavelength bands First, 254nm: 254nm is the band with the best sterilization effect, which belongs to the deep ultraviolet band, which is what we usually call UVC. This band is mainly used for sterilization. By destroying the genetic material such as DNA of bacteria and viruses, UVC changes the genetic transcription characteristics of cells, so that the organism loses the ability to synthesize and reproduce proteins, and can kill more than 99 percent of bacteria in a very short period of time. You need to be extra careful when you are in contact with this frequency band in daily operations, and the human body is very harmful. In the eye in particular, after UVC is absorbed by the cornea, the DNA of the corneal epithelial cells is damaged, the cells die, and the underlying nerve plexus is exposed. After the nerve is exposed, pain is transmitted directly to the brain until new corneal epithelial cells grow and re-cover the nerve plexus. However, although the UVC force value is very strong, it also has weaknesses. Its biggest disadvantage is its weak penetration ability, which can be blocked by ordinary plastic and glass. If you are accidentally exposed to ultraviolet rays in this band, it is best to go to the hospital and ask your doctor for advice. After talking about 254nm, let's talk about 365nm: 365nm is UVA, which belongs to shallow ultraviolet. UVA can directly pass through the clouds and reach the earth, so the sun we are in daily contact with contains a lot of UVA. This band is mainly used for curing in daily life, and the main application fields are printing, nail art, textile and so on. When we look at the teeth, this light uses UVA.
UVC bilan solishtirganda, UVA nisbatan yumshoq va ko'zning o'tkir shikastlanishiga olib kelmaydi. Ammo bu, shuningdek, sarg'aygan, quyoshdan ajinlar paydo bo'lgan teriga ham zararli, katarakta va yoshga bog'liq makula nasli- rivojlanishini tezlashtiradi. Shuning uchun, 365 nm ultrabinafsha chiroq uchun quyoshdan himoyalangan kremni qo'llang va to'g'ridan-to'g'ri ko'zingizga qaramang!
