ULTRA-VIOLET LEDs are set to play a major role in disinfecting buildings as big-brand manufacturers announced moves into the technology.
Current, powered by GE and Hubbell Lighting both unveiled LED-based continuous disinfection technology at the LightFair International trade show, significantly expanding the number of players in what has been a relatively narrow sector.
Hubbell says it signed a licensing agreement with the University of Strathclyde for access to the Scottish school’s continuous disinfection technology. Current, powered by GE has also announced continuous disinfection technology based on emission in the ultraviolet range just below the visible spectrum, and said it developed the intellectual property in house.
The concept of continuous disinfection is a compelling one with pathogens lurking in spaces ranging from athletic locker rooms to food and beverage operations to healthcare facilities.
UV-C energy will kill most pathogens almost instantly, but that spectrum – ranging from 100–280 nm – will kill healthy cells as well and is dangerous to the human eye and other organs. Light at longer wavelengths takes much longer to kill bacteria but can be used with people present.
