Automations systems and services are a key investment and growth area for the lighting market leaders as they look to take advantage of connected and smart lighting and associated wireless internet and sensor integration. One of the clear benefits is the safe implementation of UV-C systems.
One option is the use of UV-C with the automation systems of a building, such as its security system, so that it’s scheduled to operate when people aren’t around, and – with the use of motion sensors – immediately shuts down when they are.
An example of this is Puro Disinfection Lighting, who create full ceiling and mobile spectrum UV disinfection fixtures. Their devices have already been installed in hospitals, schools and more, plus are currently being trialled on buses and subways in NYC.
Air purification systems
Air handling systems also provide an opportunity to indirectly beam UV-C away from people. Take electronic firm Dynamics recently launched Nanowave Air. A portable contraption, they claim it’s “the first device to inactivate the Covid-19 in fast moving air” by “sucking up germs and blasting them with high-intensity ultra-violet light”. According to Signify and Dr. Anthony Griffiths, an associate professor at Boston University School of MedicineUV, UV-C radiation can potentially reduce the SARS-CoV-2 virus on surfaces by over 99 % within less than a minute by applying a dose of 22mJ/c.
Handheld or mobile devices
A number of manually controlled handheld and mobile UV-C emitting devices have also come to market, such as the Xenex’s Lightstrike “germ-zapping” robots. Claiming to “deactivate 99.9% of coronavirus germs in two minutes”, they’re operated with a simple start button, and have already been snapped up by a number of Hollywood Studios desperate to resume film and TV production.
A filtered UV-C that operates at a frequency of 222nm, far-UVC isn’t considered harmful to humans, yet still powerful enough to kill Covid-19 pathogens. This means it can be deployed in areas with an increased risk of Covid-19 that are rarely empty, such as hospitals. Japanese light-maker Ushio Inc have already developed the far-UVC projecting, Care 222 UV lamp, “the first indoor cleaner in the world against Covid-19” (yours for a nifty $2,870).
