Due to the aftermath of COVID-19, we are using a continuous sterilization response system, such as sterilizing the interior of the building or using sterilized air in the air conditioning system. Chemical spraying is cumbersome and requires a lot of labor, and air conditioning systems have good air cleaning functions, but sterilization functions are difficult because they require sufficient residence time. Therefore, we developed an eco-friendly sterilization system that can disinfect the entire building with a single switch by adding a sterilization function to the existing lighting. It is a concept that sterilizes the space sufficiently by combining UVC-LED with high sterilization power with the existing LED surface lighting, using lighting during the day and sterilizing light inside the building without people at night. A PIR sensor was attached to each entrance or light to stop disinfection with a human body sensor in case people enter even at night. For the sterilization performance test, it was confirmed that 99.99% of 5 types of bacteria were sterilized as a result of testing the sterilization performance of attached bacteria at the maximum height of 1.5m or less of the certification body. The radiation intensity was simulated with a value similar to the dose irradiated in the experiment to have sterilizing power at the lighting height of 2.6m in an actual general office. As a result of calculating the sterilization time of the indoor space by coding the UVC-Led specification and the office space with MATLAB as input conditions, sterilization is possible if it is more than 4 hours. Through this study, an eco-friendly smart disinfection system was developed that disinfects the entire building with one switch when UVC is combined with general lighting and controlled from the central control room.
