Abstract: An air sanitizer generates active airflow utilizing ultraviolet spectrum of light in the UV-C band (200-280 nm). The source of the UV-C is an array of light emitting diodes (LED) that shine the UV-C down a housing of the air sanitizer. A fan draws the contaminated air into the housing. The contaminated air is sanitized by the UV-C light inside the housing and is expelled through apertures at the other end of the housing. Leaking of the potential harmful UV-C light outside of the housing is eliminated by an optical baffle covering the apertures. The electronics design for the air sanitizer contains an LED driver with temperature compensation to optimize the service life of the LEDs. A UV light flux detector facing the UV-C LEDs measures the relative reduction of UV light flux over time and reports the efficacy of the UV-C LEDs during the operation of the air sanitizer.
