US 12,697,406 B2 · Targeted surface disinfection system with pulsed UV light

Abstract

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.

Claims19

Dependent claims

A targeted surface disinfection system, comprising:

a motorized articulated assembly carrying a UV source, wherein the motorized articulated assembly includes a journal supported by a chassis;
a control unit configured for driving the UV source to emit radiant energy upon a target surface requiring disinfection;
an airflow device located remote from the UV source, the airflow device including at least one of a fan and a vacuum pump, wherein the airflow device is configured to create an airstream for cooling the UV source;
an air channeling portion extending from proximate the UV source to an exhaust located remote from the UV source, wherein the air channeling portion is a channel defined by a body of an apparatus formed at least in part using the chassis supporting the motorized articulated assembly;
and
a sensor mounted proximate the UV source or the motorized articulated assembly.
