According to the Centers for Disease Control & Prevention (CDC), one in every 25 hospital patients in the U.S. will contract a hospital-acquired infection (HAI) during their visit. Often expensive and sometimes fatal, HAIs are adding billions to the country’s already bourgeoning healthcare costs.
For decades, hospitals and other healthcare facilities have employed ultraviolet germicidal irradiation systems (more recently referred to as germicidal UV or GUV), equipped with low-pressure mercury vapor lamps as an added layer of disinfection for a variety of applications ranging from operating rooms to the air circulating in the building’s ductwork.
Although effective, these lamps are inherently cumbersome and too fragile to address the growing need for smaller, lightweight, portable disinfection devices. As an alternative, medical device manufacturers are turning to deep-ultraviolet (UVC) light-emitting diodes (LEDs), which offer a substantially smaller footprint and directional UV light in the optimal 250 nm to 280 nm wavelength range for disinfection.
