Ultraviolet (UV) light is a type of radiation. It has more energy than radio waves or visible light, but less than X-rays or gamma rays. You can be exposed to ultraviolet light through natural sunlight or artificial light sources (such as tanning beds). Ultraviolet rays have been used to kill bacteria and viruses. You may have heard novel coronavirus, which is used to kill SARS-CoV-2, a COVID-19 causing disease.

In this article, we will explore how ultraviolet light is used to kill bacteria, how it effectively eliminates new coronaviruses.

UVC light can be used to kill the new coronavirus, let's see the research and test about UVC light killing new coronavirus.

Seoul Viosys and Sensor Electronics Technology Co., Ltd. ("SETi"), announced that they have successfully adopted Violeds (UVC LED) technology to kill 99.9% of the new coronavirus within 30 seconds.


In the research conducted by SETi and Seoul Viosys, Violeds (UVC LED) technology was used to demonstrate how effective it is to kill COVID-19 under 30 seconds of ultraviolet radiation. The study also found that when the coronavirus is placed closer to the light source, the longer the exposure time, the better the sterilization effect. In addition to the coronavirus, Violeds (UVC LED) technology has also been proven to successfully kill 99.9% of other harmful bacteria, such as Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, Klebsiella pneumoniae and Salmonella typhimurium, etc. Strains.


Researches on applications of uvc light for coronavirus disinfection

UVC lamp for liquid disinfection

A new study in the American Journal of Infection Control (AJIC) studied the use of UVC light to kill large numbers of new coronaviruses in wet cultures.

The study found that UVC radiation completely neutralized virus in 9 minutes.

UVC light for surface disinfection

Another study, also published in AJIC, looked at the use of a specific type of UVC light that would kill SARS-CoV-2 on the surface of the laboratory. Studies have found that UVC radiation can reduce live viruses by 99.7% within 30 seconds.

The type of UVC light used in this study is called far UVC light, which is a reliable source of UVC light with a wavelength between 207 and 222 nanometers.

Far ultraviolet lamps can still harm bacteria, but they are less harmful to the skin and eyes than other types of ultraviolet lamps.

UVC light for air disinfection

Belief Source, published in the journal Scientific Reports, used UVC-based light to study two human coronaviruses in the air. Both coronaviruses 229E and OC43 can cause the common cold in humans.

Based on their findings of these viruses, the researchers estimated that applying UVC remote control light to existing standard standards can kill 99.9% of airborne coronaviruses within 25 seconds. They believe this discovery will be extended to SARS-CoV-2.
