[0018] The foregoing summary, as well as the following detailed description of specific embodiments, will be better understood when read in conjunction with the accompanying drawings. As used herein, the singular and the preceding words "a" or "an" should be understood to refer to an element or step that does not necessarily exclude a plurality of such elements or steps. Furthermore, references to "one embodiment" are not intended to be interpreted as excluding the existence of additional embodiments that also incorporate features described herein. Furthermore, unless expressly stated to the contrary, embodiments "comprising" or "having" one or more elements having certain conditions may include additional elements that do not have those conditions.
[0019] Certain embodiments of the present disclosure provide disinfection systems and methods that include ultraviolet (UV) lamps (e.g., excimer lamps) that emit UV light in the far-ultraviolet spectrum, such as at a wavelength of 222 nm, which neutralize (e.g., kill) pathogens (e.g., viruses and bacteria) while posing no risk to humans. The UV lamps may be used within interior cabins to purify and kill pathogens. The UV lamps may be coupled to galley carts configured for use within vehicles such as commercial aircraft.
[0020] Certain embodiments of the present disclosure provide a galley cart configured for use within an interior cabin of a vehicle, the galley cart including one or more UV light sources configured to emit UV light onto surfaces of components within the interior cabin to disinfect the surfaces.
[0021] By utilizing the frame of an existing galley cart to include a UV light system, embodiments of the present disclosure provide a portable disinfection system that can be stored on board a vehicle (e.g., a commercial aircraft) and moved through the interior cabin, such as between flights, during maintenance, and / or when the vehicle is in storage. The galley carts can be half carts, full carts, etc. Because the galley carts are already sized and shaped to be used and stored within the interior cabin, they are easily used with existing vehicles, such as commercial aircraft. That is, there may be no need to provide separate and / or customized storage for the galley carts.
[0022] Certain embodiments of the present disclosure provide a galley cart for use within the interior cabin of a vehicle, such as a commercial aircraft. The galley cart includes one or more UV light sources, a power source (e.g., one or more batteries), a controller, and at least one transparent wall. In at least one embodiment, UV light from the UV light source is emitted from all sides. In at least one embodiment, the galley cart has a first compartment for UV light disinfection and a second compartment for storing food, snacks, and / or beverages.

[0060] When the galley insert 320 is in a stowed position within the insert compartment 322, a latch 330 may be engaged to secure the galley insert 320 within the insert compartment 322. Additionally, the galley insert 320 may include a plug 332 that connects with a reciprocal receptacle 334 within the insert compartment 322 so that a power source (e.g., one or more batteries) of the galley insert 320 can be charged and recharged.
[0061] The galley insert 320 may be removed from the insert compartment 322 and placed in a location within the interior cabin to disinfect the surfaces of the components. For example, the galley insert 320 may be positioned in the flight deck, seating area, restroom, etc. within the interior cabin, and the UV light source 260 may be activated to emit light to disinfect various surfaces. Additionally, the galley insert 320 may be positioned in the galley cart 200 (e.g., as shown in FIGS. 4-15).
[0062] Figure 17 illustrates an ultraviolet light spectrum. Referring to Figures 4-17, in at least one embodiment, UV light source 260 is configured to emit disinfecting UV light in the far ultraviolet spectrum, such as from 200 nm to 230 nm. In at least one embodiment, UV light source 260 emits disinfecting UV light having a wavelength of 222 nm.
[0063] Disinfecting UV light with a wavelength of 222 nm has been found to kill pathogens (e.g., viruses and bacteria) instead of inactivating them. In contrast, UVC light with a wavelength of 254 nm inactivates pathogens by disrupting their DNA, resulting in a temporary inactive state, but not killing them. Instead, pathogens can be reactivated by exposure to normal white light at a reactivation rate of approximately 10% per hour. Therefore, UVC light with a wavelength of 254 nm may not be effective in illuminated areas, such as the interior cabin of a vehicle. Furthermore, 254 nm UVC light is not recommended for human exposure because it can penetrate human cells.
[0064] In contrast, disinfecting UV light with a wavelength of 222 nm is safe for human exposure and kills pathogens. Furthermore, disinfecting UV light with a wavelength of 222 nm can be emitted at full power within 1 millisecond of UV light source 260 being activated (in contrast, UVC light with a wavelength of 254 nm can take several seconds or even minutes to reach full power).
[0065] Alternatively, the UV light source 260 may emit disinfecting UV light at a wavelength other than 220 nm to 230 nm. For example, the UV light source 260 may emit disinfecting UV light between 230 nm and 280 nm in the UVC spectrum.
[0066] Figure 18 is an end perspective view of a UV light source 260, according to one embodiment of the present disclosure. The UV light source 260 shown in Figure 18 is merely exemplary. The UV light source 260 may be configured other than as shown and described.
[0067] In at least one embodiment, UV light source 260 includes UV lamp 440 and reflector 442. For example, UV lamp 440 and reflector 442 may be secured within a shroud. In at least one embodiment, reflector 442 may be secured to the underside of the shroud, such as via one or more adhesives. In another embodiment, reflector 442 is an integral part of the shroud. For example, reflector 442 may be the underside of the shroud or may otherwise provide the underside of the shroud. Reflector 442 provides a reflective surface 443 (e.g., formed from Teflon, mirrored, etc.) configured to reflect UV light emitted by UV lamp 440 outward. In at least one embodiment, the shroud may be or include an outer shell formed from fiberglass, and reflector 442 may be formed from Teflon, which provides 98% reflectivity.
[0068] The reflector 442 may extend along the entire length of the underside of the shroud. Optionally, the reflector 442 may extend along less than the entire length of the underside of the shroud.
[0069] The UV lamp 440 can extend along the entire length (or substantially the entire length). For example, the UV lamp 440 can be secured to the reflector 442 and / or to the shroud via one or more brackets. The UV lamp 440 can include one or more UV light emitters, such as one or more bulbs, light-emitting elements (e.g., light-emitting diodes), etc. In at least one embodiment, the UV lamp 440 is configured to emit UV light in the far-ultraviolet spectrum, such as wavelengths of 200 nm to 230 nm. In at least one embodiment, the UV lamp 440 is configured to emit UV light having a wavelength of 222 nm. For example, the UV lamp 440 can be or include a 300 W bulb configured to emit UV light having a wavelength of 222 nm.
[0070] As shown, the reflector 442 includes flat, straight side walls 444 connected together via a top curved wall 446. The top curved wall 446 may bow outward away from the UV lamp 440. For example, the top curved wall 446 may have a parabolic cross section and / or profile.
[0071] It has been found that straight, linear sidewalls 444 provide the desired reflection and / or focusing of UV light emitted from UV lamps 440 toward or onto desired locations. Alternatively, sidewalls 444 do not have to be linear and flat.
[0072] Figure 19 is an end perspective view of a UV light source 260 according to one embodiment of the present disclosure. The UV light source 260 shown in Figure 19 is merely exemplary. The UV light source 260 may be configured other than as shown and described. The reflector 442 shown in Figure 19 is similar to the reflector 442 shown in Figure 18, except that the side walls 444 may be angled outward from the top curved wall 446.
[0073] 20 is an end perspective view of a UV light source 260 according to one embodiment of the present disclosure. The UV light source 260 shown in FIG. 20 is merely exemplary. The UV light source 260 may be configured other than as shown and described. In this embodiment, the side walls 444 may curve to follow the curvature of the top curved wall 446.
