Abstract: A new UVC sterilization device for elevator buttons, which comprises of several UVC LEDs on an enclosed polymer body, equipped with an infrared sensor to provide signals when an object comes within a certain distance, along with a controller printed circuit board that drives the unit by providing a constant current for the disinfection LEDs, as well as a battery. The infrared sensor is connected with the MCU control unit in the main body through the infrared detection unit. The MCU control unit is connected with the LEDs through the LED control unit. The main body is mounted on the elevator wall by two brackets. These brackets mechanically hold the main body in place and align the LED rays towards the buttons. The product is small and compact, easy to carry and install, and proven to be effective against microbes which would ultimately reduce bacterial and virus transmissions.
