Care must be taken however, when servicing these components, as the exposure to ultraviolet light can be hard to avoid, due to no natural avoidance. UVC lamps can be an ideal solution to ensure decontaminated air by cleaning HVAC components for environments such as hospitals or schools. Therefore, the lamps can sterilise workplaces and tools. UV-C radiation is known for the disinfection of air, water, and some surfaces to reduce any risk infections from bacteria or viruses and protozoa. Such systems are safe to use with people in the room as the UV-C disinfection takes place in a contained and sealed chamber.UVC lamps can also be called germicidal lamps they produce short-wave ultraviolet light. At the press of a button, items placed inside the chamber are disinfected in just five minutes. The latter looks like an industrial microwave oven and was conceived for biosecurity in the agri-business sector. These draw on our experience with the Once BioShift germicidal chamber. Surface disinfection lends itself to high contact areas such as offices, schools, restrooms and gyms.įor surface disinfection of small objects, such as mobile phones, laptops and wallets, a new range of chambers will be introduced. Where UV-C scores highly is that it saves on time, requires few to no people and no chemicals. So, for areas requiring deep disinfection it is recommended that UV-C forms part of a multi-barrier approach, alongside traditional scrubbing and cleaning with chemical disinfectants. Of course, the light won’t be able to reach areas in shadow. Typical surface disinfection lamps are 55W and depending on the dose, disinfection can be done in seconds or a matter of minutes. An extra level of safety may be provided by remote on-off switches and sensors which can shutdown systems if people or animals are detected. They can be brought into a workplace or bus or train when people have left. Let’s take a look at the different forms of disinfection,ĭisinfection of surfaces is performed through direct exposure to the UV-C radiation from lamps, luminaires or disinfection carts that are activated when people are not present. Signify’s new UV-C product range include battens, luminaries and carts for surface disinfection, air disinfection systems and a series of chambers for the speedy disinfection of objects and instruments. Based on the data, it was determined that a dose of 22mJ/cm2 will result in a reduction of 99.9999% in 25 seconds. The team applied a dose of 5mJ/cm2, resulting in a reduction in the virus of 99% in 6 seconds. Last June, Boston University validated our UV-C lighting as effective in inactivating SARS-CoV-2, the virus causing COVID-19. In fact, it has rendered inactive all bacteria and viruses tested to date (many hundreds over the years including coronaviruses). Their peak wavelength of 254 nm is close to the 260-265 nm germicidal peak and proven to be extremely effective in breaking down the DNA (and RNA) of bacteria, viruses, fungi and mold spores, rendering them inactive and harmless.įor years, UV-C has been used to disinfect drinking water, wastewater, air, pharmaceutical products, and surfaces against a whole suite of pathogens. Our conventional Philips UV-C lamps have the same familiar shape as our well-known fluorescent tubes. Signify has been involved in UV-C lighting for more than 35 years.
