Targeted surface disinfection system with pulsed UV light
Embodiments of a targeted surface disinfection system are disclosed. The system includes a set of one or more UV lamps, a high voltage power supply for driving the lamps, a mobile carriage including a chassis supporting the set, an articulated head assembly including at least one UV lamp from the set, a vacuum pump, and a suction hose extending between the vacuum pump and the head assembly for dissipating heat generated by the at least one UV lamp. The system also includes a pulse configuration control unit for configuring an output of the high voltage power supply for driving the set to emit a UV radiant energy upon a target surface requiring disinfection, where the set of one or more UV lamps emits the UV radiant energy at a rate of at least 20 pulses per second.
