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.
Claims20
An apparatus, comprising:
- an ultraviolet (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.
An apparatus, comprising:
- an ultraviolet (UV) light source to direct UV light onto an area;
- and
- a gas outlet to disperse oxygen-depleted gas perpendicular to the UV light of the UV light source, such that the UV light passes through the oxygen-depleted gas onto the area.
An apparatus, comprising:
- an ultraviolet (UV) light source to direct UV light onto an area;
- and
- a gas outlet to disperse oxygen-depleted gas over the UV light source, wherein the gas outlet and the UV light source are positioned in a lavatory on an aircraft, and wherein:
- the UV light source operates to emit the UV light when the lavatory is not in use;
- and
- the gas outlet disperses the oxygen-depleted gas over the area so as to displace air that is in a path of the UV light while the UV light source is emitting the UV light.
