Apparatuses and methods for reducing ozone creation from ultraviolet (UV) light

Abstract:

Apparatuses and methods are described for use of an ultraviolet (UV) light source, such as in a cleaning device, in which ozone creation due to reaction of the UV light with oxygen in the air is reduced. An example method includes dispersing, by a gas outlet, oxygen-depleted gas over a UV light source, and directing UV light from the UV light source to pass through the oxygen-depleted gas onto an area. An example apparatus includes a UV light source to direct UV light onto an area, and a gas outlet to disperse oxygen-depleted gas over the UV light source, such that the UV light passes through the oxygen-depleted gas onto the area.
