A recently granted patent (Publication Number: US11883546B2) discloses an antimicrobial system designed to disinfect a space by emitting ultraviolet (UV) light in the range of 200 to 230 nanometers. The system includes a disinfection light control device, a luminaire with a disinfection light source, a driver circuit, and a luminaire control circuit with exposure and dosage control programming. The system is capable of controlling the emission of disinfection light continuously or in intervals to achieve a desired level of pathogen reduction while ensuring safe exposure levels for humans. Additionally, the system features a disinfection status indicator to display the disinfection state of the vicinity, providing real-time feedback on the disinfection process.

Furthermore, the antimicrobial system includes advanced functionalities such as adjusting UV radiation exposure levels based on human presence, increasing disinfection light emission to accelerate pathogen deactivation, and monitoring the cumulative on-time of the disinfection light source to optimize future disinfection cycles. The system also incorporates multiple disinfection light control devices and luminaires for disinfecting different areas, each with its own control signal and dose cycle management. Additionally, a pathogen sensor with a spectrometer and sense circuit is utilized to detect the presence of target pathogens in the vicinity, enhancing the system's effectiveness in pathogen eradication. Overall, the patented antimicrobial system offers a comprehensive and intelligent solution for efficient and safe disinfection in various environments.
