Italian lighting brand Artemide has developed a way of turning lamps into room sanitisers that emit antiviral ultraviolet light when people are not around.
Called Integralis, the patented technology can be fitted to light fixtures and programmed via an app to emit normal light when rooms are occupied and ultraviolet (UV) rays when they are empty.
While invisible UV light can kill pathogens including viruses, it can be harmful to humans. However, the blue spectrum of visible light can also have an anti-microbial effect.
