Lockdown is now behind us, but residual effects of the “Covid-19” emergency are still here. Restarting, with all precautions, cannot be separated from workplace safety: social distancing, masks and healthy environments, the basis for limiting risks and not having to return to “house arrest”.
In this perspective C-Led worked. C-Led is a Cefla company specialized in the design and production of personalized lighting solutions that respond to customer requirements and this company created a solutions based on ultraviolet light produced by LED lamps can be used to stop the spread of bacteria, spores and viruses without using any chemicals and can module to help make rooms, machinery and production facilities safer.
“Our UV-C LED modules are extremely versatile. They can be integrated into a great many applications being developed by our customers, especially now, in every sector”, said Managing Director Alessandro Pasini. “Because of the health emergency, in fact, we’re receiving a huge number of requests and are working hard to respond to every single one so we can, as soon as possible, design the countless customized solutions requested of us”.
A study published in ASC Photonics, a scientific journal published by the American Chemical Society) confirmed effectiveness of ultraviolet light. In Italy this field of study has involved INAF (the National Institute of Astrophysics). In fact, together with the University of Milan, the National Cancer Institute of Milan and the IRCCS Don Gnocchi Foundation, INAF experimentally assessed the effects of UV-C irradiation on the Sars-Cov-2 virus by testing the lighting levels that neutralize the virus or inhibit its replication.
“UV technology applied to LED lamps can be effective in reducing the amount of bacteria, the virulence of harmful organisms and the presence of pathogens while breaking down volatile organic compounds, resulting in a reduction of foul odours in general. Germicidal irradiation with ultraviolet rays appears to be an effective method for sanitising and disinfecting air and the surfaces of materials”, explained C-LED’s researchers. “By using shorter-wavelength ultraviolet light, around 260 nanometers, it might be possible to destroy the DNA or RNA of bacteria and viruses, leaving them unable to perform some of their vital cellular functions, thus resulting in the complete sterilisation of water and surfaces”
C-Led: lights on emergency. Literally.
