August 11, 2021 (Newswire.com) –
Ushio America, Inc. (“Ushio”; http://www.ushio.com) introduced in the present day that its strategic associate Acuity Manufacturers Lighting, Inc. (NYSE: AYI) (“Acuity Manufacturers”) has efficiently secured a certification by UL LLC for the mixture of Ushio Care222® filtered Far UV-C expertise with Acuity Model’s newly developed (patent-pending) UV dosing controls. That is the primary germicidal UV (GUV) supply within the wavelength vary 200-230 nm (i.e., “far-UVC”) to be UL LLC Licensed to fulfill U.S. and Canadian requirements for germicidal gear to be used in occupied areas. When correctly put in and administered, the module is within the Exempt threat group for photobiological hazards, as described within the IEC 62471:2006, Photobiological security of lamps and lamp programs.
The UL Acknowledged Element certification paves the way in which for incorporating Ushio’s Care222 expertise into quite a lot of Acuity Manufacturers LED lighting merchandise, which will probably be absolutely UL Licensed to ship a measured 222nm UVC dosage with folks current. These lighting merchandise present a 222nm UVC dosage that may successfully goal pathogens1 all through the day in occupied areas akin to faculties, hospitals, manufacturing, hospitality and retail whereas sustaining a natural-looking mild emittance.
Shinji Kameda, COO of Ushio America, Inc., said, “The event of the world’s first UL listed Far UV-C included lights is a significant achievement for each Acuity Manufacturers and Ushio and is a large step ahead for the lighting business in recognizing the adoption of filtered Far UV-C mild for disinfection* in occupied areas. Ushio is honored to be part of this improvement mission and can try to repeatedly enhance and evolve our Care222 expertise in collaboration with our companions to assist in the struggle in opposition to present and future pandemics.”
Ushio’s Care222 expertise makes use of filtered excimer lamps to generate 222nm Far UV-C mild. The mercury-free excimer lamps characteristic a specifically designed brief go filter, primarily based on groundbreaking analysis and expertise developed by Columbia College, which filters out longer UV wavelengths which might be probably dangerous to people. The result’s a slim band 222nm wavelength of UV mild that may inactivate viruses and micro organism, successfully stopping them from replicating. With out this filter, excimer lamps would want to ship a lot decrease doses of UV to work inside established publicity pointers, which suggests they’d not work as rapidly.
“The certification of the Care222 module to be used in lighting merchandise in occupied areas is the results of rigorous testing and analysis carried out by UL scientists working along with analysis and improvement groups from Acuity Manufacturers and Ushio America, Inc. in what has develop into a breakthrough class in GUV product improvement. The certification course of adopted by UL included an evaluation in opposition to IEC 62471 for the GUV module when put in and used based on directions,” stated Ron Schimmelpfenning, Vice President-Design Options, Acuity Manufacturers Lighting, Inc.
Outcomes from laboratory testing and medical research recommend that the filtered Far UV-C mild emitted from the Care222 lamp can cut back recognized viruses and different pathogens, together with the SARS-CoV-22 on surfaces and in air. When used inside applicable parameters, the 222nm wavelength emitted from the Care222 lamp inactivates viruses and micro organism at power ranges that don’t penetrate dwelling tissue in pores and skin or past the tear layer in eyes, permitting areas through which the lamps are used to stay occupied throughout use. In distinction, doable acute and persistent injury to eyes and pores and skin could end result from the extra typically employed 254nm UV wavelength utilized in many germicidal lamps except they’re used underneath circumstances that sharply restrict human publicity.
An essential a part of the combination of Care222 expertise into Acuity Manufacturers lights was the creation of patent-pending UV dosing controls by Acuity Manufacturers. These digital controls permit for extremely exact administration of UVC doses to focus on pathogens1 in occupied or unoccupied areas. The finished module is an outgrowth of the 2020 strategic alliance settlement between Acuity Manufacturers and Ushio that granted Acuity Manufacturers unique rights in North America to include Ushio’s Care222 Far UV-C disinfection expertise into Acuity Manufacturers luminaires.
Acuity Manufacturers is now within the means of seamlessly incorporating the Care222 Far UV-C disinfection modules in acquainted luminaires and stand-alone merchandise from its a number of lighting manufacturers, making a full lineup of UL Licensed far-UVC-enabled luminaires that includes Care222 merchandise from Ushio.

2 In a 2020 research, Hiroshima College confirmed that underneath laboratory circumstances, a dose of three mJ/cm2 of 222nmUVC irradiation, with an publicity time of 30 seconds inactivated 99.7% of SARS-CoV-2 on a floor. Ushio’s Care222 UV-C disinfection module was positioned 24 cm above the floor of the plates through which the viral samples had been positioned.
