Ultraviolet c-band air sanitizer

An air sanitizer comprising:

• a housing;
• a heatsink;
• a printed circuit board (PCB) attached to the heatsink;
• a plurality of ultraviolet C light emitting diodes (UV-C LEDs) attached to the PCB;
• one or more temperature sensors monitoring temperature of the heatsink or temperature of the PCB;
• an electronic circuit supplying and controlling electrical power to the plurality of UV-C LEDs based on a predetermined optical power level and temperature output values of the one or more temperature sensors, and reporting a status of the air sanitizer to a user;
• a fan assembly drawing external air into the housing for cooling the heatsink;
• a layer of UV-reflective material in the housing, the layer of UV-reflective material facilitating a plurality of reflections of UV-C light so as to improve utilization of the UV-C light;
• one or more apertures at a downstream of the housing so as to expel sanitized air;
• one or more UV-blocking optical baffles covering the one or more apertures;
• and
• an optical flux meter system in the housing, the optical flux meter system being in a path of the UV-C light emitted from the plurality of UV-C LEDs.
