A recently filed patent (Publication Number: US20240033383A1) describes a disinfection system designed for vehicles. The system includes two light sources positioned within the vehicle's interior, with one generating radiation in the 100-300 nm range and the other in the 210-230 nm range. The second light source is specified to emit radiation with a concentration of at least 12 mJ/cm2. Additionally, the system features a controller to manage the operation of the light sources and an identification unit, such as a camera or radar, to detect passengers inside the vehicle.

Furthermore, the patent outlines a method for controlling the disinfection system, involving the controller determining the presence of passengers based on information from the identification unit and activating the appropriate light source accordingly. If no passengers are detected, the first light source operates for a minimum of 6 seconds, while the second light source is activated for at least 2.5 seconds when passengers are present. The patent also includes details on the positioning of the light sources within the vehicle's interior, such as on the roof, bearing pillar, or console, ensuring effective radiation propagation for disinfection purposes.
