Abstract
An ultraviolet (UV) light sanitizing system is configured to sanitize a structure. The UV light sanitizing system includes a UV light assembly that is configured to emit UV light onto the structure, and a UV light emission control unit coupled to the UV light assembly. The UV light emission control unit is configured to control the UV light assembly to emit UV light onto the structure within at least a first UV band and a second UV band that differs from the first UV narrow band during a sanitizing cycle that sanitizes the structure. The UV light within the first and second UV bands is configured to kill at least one type of microbe.
Claims20
An ultraviolet (UV) light sanitizing system configured to sanitize a structure, the UV light sanitizing system comprising:
- a UV light assembly that is configured to emit UV light onto the structure;
- and
- a UV light emission control unit coupled to the UV light assembly, wherein the UV light emission control unit is configured to control the UV light assembly to separately emit UV light onto the structure within at least a first UV band and a second UV band that differs from the first UV band during a sanitizing cycle that sanitizes the structure, and wherein the UV light within the first and second UV bands is configured to kill at least one type of microbe.
An ultraviolet (UV) light sanitizing method configured to sanitize a structure, the UV light sanitizing method comprising:
- coupling a UV light emission control to a UV light assembly;
- and
- emitting UV light from the UV light assembly onto the structure, wherein the emitting comprises using the UV light emission control unit to control the UV light assembly to separately emit the UV light onto the structure within at least a first UV band and a second UV band that differs from the first UV band during a sanitizing cycle that sanitizes the structure, and wherein the UV light within the first and second UV bands is configured to kill at least one type of microbe.
A vehicle comprising:
- an internal cabin;
- a lavatory within the internal cabin;
- and
- an ultraviolet (UV) light sanitizing system that is configured to sanitize at least one structure within the lavatory, the UV light sanitizing system comprising:
- a UV light assembly that is configured to emit UV light onto the at least one structure, wherein the UV light assembly comprises a plurality of UV light elements;
- and
- a UV light emission control unit coupled to the UV light assembly, wherein the UV light emission control unit is configured to control the UV light assembly to separately emit UV light onto the at least one structure within at least a first UV band and a second UV band that differs from the first UV band during a sanitizing cycle that sanitizes the at least one structure, wherein the first UV band comprises one of a far UV light range, a UVC light range, a UVB light range, a UVA light range, or a vacuum UV light range within the UV spectrum, wherein the second UV band comprises another of the far UV light range, the UVC light range, the UVB light range, the UVA light range, or the vacuum UV light range, and wherein the UV light within the first and second UV bands is configured to kill at least one type of microbe.
