According to a study, Ultraviolet (UV) light-emitting diodes (UV-LEDs) can kill the novel coronavirus efficiently, quickly, and cheaply. This new innovation could be installed in air conditioning and water systems.
The research, published in the Journal of Photochemistry and Photobiology B: Biology, assessed the disinfection efficiency of UV-LED irradiation at different wavelengths on a virus from the family of coronaviruses, which includes COVID-19-causing SARS-CoV-2.
“Disinfection systems based on LED bulbs, however, can be installed in the ventilation system and air conditioner, for example, and sterilise the air sucked in and then emitted into the room,” Ms Mamane said.
Hadas Mamane, co-author of the study from the American Friends of Tel Aviv University in the US, said “disinfection systems based on LED bulbs, however, can be installed in the ventilation system and air conditioner, for example, and sterilize the air sucked in and then emitted into the room,”
According to her, they discovered that it is quite simple to kill the coronavirus using LED bulbs that radiate ultraviolet light. They killed the viruses using cheaper and more readily available LED bulbs, which consume little energy and do not contain mercury like regular bulbs.
The bulbs can be installed in air conditioning, vacuum, and water systems, with necessary adjustments and thereby be able to efficiently disinfect large surfaces and spaces.
The system must be designed so that a person is not directly exposed to the light, adding that it is very dangerous to use the UV-LED to disinfect surfaces inside homes, researchers said.
