የ UVC መብራት ቫይረሶችን እና ባክቴሪያዎችን ይገድላል?

ሰዓት: 2020-04-21

For decades, scientists have been devoted to the research of UVC light for disinfection, especially when the UVC market is huge and the human pursuit of health is more important than ever before.


More and more reports indicate that UVC light products can kill viruses and bacteria higher than a 99.9% rate, which directly leads to the crazy purchase of UVC products.


But in fact, few people know exactly what UVC light is and whether UVC light is useful for sterilization.

ቀጥሎም በዝርዝር እንብራራለን what UVC lights are, how they work, their precautions for use and some commercial applications ግልፅ የሆነ ግንዛቤ እንዲያገኙ ለማገዝ ፡፡

Wha is UVC light?


ሁላችንም እንደምናውቀው የፀሐይ ብርሃን በተለያዩ የሞገድ ርዝመት ውስጥ የብርሃን ኃይል ድብልቅ ነው ፡፡


የሞገድ ርዝመት ከ 380 ናኖሜትሮች (ኤንኤ) እስከ 780 ናኖሜትሮች (nm ድረስ ድረስ) ብርሃን ተብሎ ይጠራል ፣ ከርቀት ወሰን ክልል ውጭ ያሉት ግን የማይታይ ብርሃን ይባላል ፡፡

Ultraviolet light is a type of invisible light ranging from 10 nm to 400 nm. And the function of UV light depends on the range of wavelength.

  • UV-A: 320nm to 400 nm

It makes up the majority of UV light reaching the Earth. And it can damage our skin.

  • UV-B: 280nm to 320nm

የቆዳ በሽታዎችን ማከም ይችላል ፡፡ ግን ከመጠን በላይ መጋለጥ የፀሐይ መከላከያ እና የቆዳ ካንሰር እንኳን ያስከትላል። እና ከ UV ofርሰንት 2% ብቻ ወደ ምድር መድረስ ይችላል።

  • UV-C: 200nm to 280nm

It is particularly good at sterilizing. But its penetration ability is very weak. Before reaching the ground, all UVC light will be absorbed by ozone in the atmosphere. That means, standing under the sun is useless for sterilization.

  • In summary: UV light Rule

አጭር ሞገድ ርዝመት ፣ ኃይሉ ጠንካራ ይሆናል ፣ ደካሙ ግን ወደ ውስጥ ስለሚገባ በፍጥነት ይጠፋል ፡፡

Related Knowledge: Which UV light is the best?

Because UVC light can be used for sterilization, coupled with the epidemic environment, the market demand for UVC products can be described as Crazy now.

የገበያው ዋጋም እንኳ ከ 140,000,000 የአሜሪካ ዶላር ወደ 500,000,000 የአሜሪካ ዶላር ያህል አድጓል ፡፡

The big question right now may be how does UVC light work and can it kill viruses & bacteria?


How does UVC light work?


Before the deep study of UVC light, I thought all sunlights have the sterilization effect. Bacteria and viruses will be killed by "sunburn" or heat.

But that's not the truth.


  • Sterilization Principle of UVC light


In fact, UVC light will destroy the DNA or RNA of the bacteria & viruses, without the use of chemicals, making them inactive and unable to reproduce.

Since the lifespan of single bacteria & viruses is very short, once they lose the reproduce ability, it means death. So the purpose of sterilization has been achieved.


In scientific research, it has been found that UVC light can use very little time to finish the disinfection process and make most microbes reduction up to 99.99%.


Research of UVC light

Based on this information, UVC light is believed to be quiet effective at killing viruses and bacteria.


However, the vitality of different viruses and bacteria are different. Some bacteria&viruses may be injured once they are exposed to UVC light, while others are not.

  • Special requirements of UVC lights

At present, there are no specific figures to show how much UV dose flu viruses needs to be killed. Maybe 1,085 mJ / cm2 or 3,640 mJ / cm2 . Anyway, a huge number.

You may be wondering if we stand under the sunlight containing UVC light, can we be disinfected by it?

Unfortunately, the answer is no. Although the sterilization ability of UVC light is extremely strong, the penetration ability to objects (including air) is extremely weak. Before reaching the ground, all UVC light will be filtered out by ozone in the atmosphere.

Please pay attention to the fact that most UV lamps on the market are only designed to meet the common standard, that is, 40mJ / cm2 UV dose required for a 99.99% inactivation rate.


Study result of UVC light

Further considering the decay of UVC light in the air, those lamps make no sense for disinfection.

ስለዚህ አንዳንድ ኩባንያዎች “ቫይረሶችን እና ባክቴሪያዎችን መግደል እንችላለን” የሚለውን አባባል በቀላሉ አያምኑ ፣ አንዳንድ ጊዜ የግብይት ቋንቋ ብቻ ነው።

Are ultraviolet lamps containing uvc light safe?


Although UVC light can indeed kill viruses and bacteria, there are various problems with household ultraviolet disinfection lamps on the market:
