FIELD OF THE DISCLOSURE

Embodiments of the present disclosure generally relate to sanitizing systems, such as may be used to sanitize structures and areas within vehicles, and more particularly to systems and methods that sanitize components with ultraviolet (UV) light.

BACKGROUND OF THE DISCLOSURE

Vehicles such as commercial aircraft are used to transport passengers between various locations. Systems are currently being developed to disinfect or otherwise sanitize surfaces within aircraft, for example, that use ultraviolet (UV) light.

A UV light sanitizing system typically includes a UV lamp that includes a plurality of UV light emitters. The UV lamp is formed by integrating the various UV light emitters into a single housing and coupling the UV light emitters to a separate power supply.

As can be appreciated, the UV lamp can have numerous UV light emitters. The process of manufacturing such a UV lamp is time and labor intensive. Further, if one or more of the UV light emitters malfunctions, replacing such may also prove time and labor intensive.

Further, in various settings, UV light disinfection occurs when an area is unoccupied. For example, a lavatory within an aircraft can be disinfected with UV light. However, such disinfection typically does not occur when an individual is within the lavatory.

Additionally, during operation, UV light emitters can generate electromagnetic interference (EMI), which can affect operation of the UV lamp and/or other devices.

DETAILED DESCRIPTION OF THE DISCLOSURE

Certain embodiments of the present disclosure provide a system for disinfecting (for example, sanitizing, decontaminating, cleaning, or the like) one or more components. The system includes a plurality of modules coupled together to form a UV lamp. Each of the plurality of modules includes one or more UV light emitters that are configured to emit UV light onto a component to disinfect the component. In at least one embodiment, each of the modules also includes a power supply coupled to the UV light emitters. The modules can also include a band pass filter that is configured to filter the generated UV light from the UV light emitters to a desired wavelength, such as within the far UV spectrum, the UVC spectrum, or the like. In at least one embodiment, different modules can emit UV light at different wavelengths. For example, a first module can emit UV light within the far UV spectrum, while a second module coupled to the first module can emit UV light within the UVC spectrum.

Multiple modules may be coupled together (for example, stacked, ganged, or otherwise connected together) as desired for a greater area of UV coverage. Such configuration can be determined based on the size of the surface to be sanitized. The modules can be coupled together through bonding, one or more mechanical connectors or fasteners, and/or the like.

The UV lamp formed by multiple modules can be customized to fit into desired areas. As such, the UV lamp can be compact and configured to fit into small, confined spaces.

In at least one embodiment, the UV lamp is part of a wand assembly that is configured to be held by an operator. In at least one other embodiment, the UV lamp is a fixture within a space, such as within a lavatory. The UV lamp can be fixed in position within the space. Optionally, the UV lamp can be configured to be moved between a stowed position and a deployed position within the space.

In at least one embodiment, the system includes an infrared (IR) sensor in communication with a control unit. The IR sensor is configured to detect IR light, such as a beam of IR light emitted from an IR source, which can be reflected to the IR sensor. In operation, the control unit is also in communication with the one or more UV light emitters. The control unit is configured to selectively activate and deactivate the UV light emitters in response to a signal received from the IR sensor. For example, the control unit prevents activation of the UV light emitters and/or deactivates the UV light emitters in response to the IR sensor not detecting the IR light.

For example, an IR source and/or an IR reflector can be positioned within a location, such as proximate to (for example, on or within a foot or less) a lavatory door. The IR sensor is configured to monitor the IR beam and to detect a change when an occupant crosses a threshold. Additionally the system can include a door sensor (such as a door hall effect sensor) installed on and/or proximate to the door to detect when the door is open or closed. The control unit can also be in communication with the door sensor and is configured to selectively activate and deactivate the UV light emitters in response to one or more IR signals received from the IR sensor and/or the door sensor.

In at least one embodiment, the control unit is configured to deactivate the UV light emitters when an area (such as a lavatory) is occupied, and to activate the UV light emitters when the area is unoccupied. Integrating the IR sensor into the UV lamp reduces cost and installation time.

Certain embodiments of the present disclosure provide a sanitizing system and method that includes an ultraviolet (UV) lamp (such as an excimer lamp having one or more UV light emitters, such as light emitting diodes, bulbs, and/or the like) that emits UV light in a far UV light spectrum, such as at a wavelength of 222 nm, which neutralizes (such as kills) microbes (for example, viruses and bacteria), while posing no risk to humans. Optionally, the UV lamp emits the UV light in the UVC spectrum, such as at a wavelength of 254 nm. The UV lamp may be used within an internal cabin to decontaminate and kill pathogens. The UV lamp may be used in a portable sanitizing system or a fixed sanitizing system. For example, operating the UV lamp to emit sanitizing UV light having a wavelength within the far UV spectrum or UVC spectrum may be used with a portable system or a fixed system.

FIG. 1illustrates a schematic block diagram of a system100for disinfecting a component102, according to an embodiment of the present disclosure. The component102can be any structure that is to be disinfected with UV light. For example, the component102can be a structure within a vehicle, a fixed building, or the like. As example, the component102can be a passenger seat within a vehicle, a portion of a lavatory (such as a toilet, sink, door handle, and/or the like), a counter or other such surface within a kitchen or galley, and/or the like.

The system100includes a UV lamp104that includes a plurality of modules106coupled together. For example, the UV lamp104includes a first module106coupled to a second module106. Optionally, the UV lamp104can include more than two modules106.

Each module106includes one or more UV light emitters108that are configured to emit UV light through an aperture112. The UV light emitters108can emit UV light within the far UV spectrum, such as between 200 nanometers (nm)-230 nm. For example, the UV light emitters can emit UV light at 222 nm. As another example, the UV light emitters108can emit UV light within the UVC spectrum, such as between 230 nm and 280 nm. For example, the UV light emitters can emit UV light at 254 nm. In at least one embodiment, the UV light emitters108of the modules106emit UV light at the same wavelength. In at least one other embodiment, the UV light emitters108of the modules106emit UV light at different wavelengths. For example, the UV light emitters108of a first module106emit UV light within the far UV spectrum, and the UV light emitters108of a second module106emit UV light within the UVC spectrum, or vice versa.

The modules106are coupled together to form the light emitting portion of the UV lamp104. The modules106can be removably coupled together. As such, the UV lamp104provides a modular assembly that can be customized to a desired size, shape, and lighting capability. Further, if a module106is in need of repair, the module106can be removed from the UV lamp104and replaced within another module106. Accordingly, the modules106allow for efficient production and maintenance of the UV lamp104.

In at least one embodiment, portions of the modules106are covered with one or more electromagnetic interference (EMI) shields114. For example, in at least one embodiment, the one or more UV light emitters108are surrounded on one or more surfaces with an EMI shield114, with the aperture112being uncovered by the EMI shield114. In at least one embodiment, the EMI shield114is a metal cover, such as a foil formed of aluminum, steel, or the like that covers a housing of the module106with the aperture112remaining uncovered. Optionally, the modules106do not include the EMI shield114.

The UV lamp104can be part of a wand assembly, which is configured to be held by an individual. The wand assembly can be coupled to a backpack assembly, a case assembly, a cart, and/or the like. As another example, the wand assembly can be a standalone assembly that is not coupled to a backpack assembly, a case assembly, a cart, or the like.

As another example, the UV lamp104can be a fixture within an area. For example, the UV lamp104can be secured within a lavatory, galley, kitchen, or various other areas. The UV lamp104can be fixed in position within the area. Optionally, the UV lamp104can be moveable between a stowed position and a deployed position within the area.

In at least one embodiment, the system100also includes an infrared (IR) sensor116in communication with a control unit118, such as through one or more wired or wireless connections. The control unit118is also in communication with the UV light emitters108of the modules106, such as through one or more wired or wireless connections. In at least one embodiment, the UV lamp104includes the IR sensor116and/or the control unit118. Optionally, the IR sensor116and/or the control unit118can be remotely located from the UV lamp104.

In operation, the control unit118selectively activates and deactivates the UV light emitters108based on an IR signal emitted by and received from the IR sensor116. For example, the IR sensor116is configured to receive an IR light signal119emitted by an IR source120, either directly from the IR source120, or indirectly from a reflector that receives and reflects the IR light signal119from the IR source120. When the IR sensor116receives the IR light signal119, the IR sensor116outputs a sensed IR signal122to the control unit118. Based on the received sensed IR signal122, the control unit118activates the one or more UV light emitters108to emit the UV light. If, however, the IR sensors116does not receive the IR light signal119(such as if the IR light signal119is blocked by an individual), the IR sensor does not output the sensed IR signal122to the control unit118. In response to not receiving the sensed IR signal122, the control unit118deactivates the UV light emitters108so that they do not emit the UV light.

In at least one embodiment, an activation switch124is in communication with the control unit118, such as through one or more wired or wireless connections. The activation switch124can be secured to the UV lamp104. That is, the UV lamp104can include the activation switch124. Optionally, the activation switch124can be remotely located from the UV lamp104. When the activation switch124is engaged to activate the UV light emitters108, the control unit118operates as explained above (that is, the control unit118selectively activates and deactivates the UV light emitters based on the signal received from the IR sensor116). When the activation switch124is disengaged so that the UV light emitters108are not to emit the UV light, the control unit118maintains the UV light emitters108in a deactivated state even if the sensed IR signal122is received from the IR sensor116. Optionally, the system100may not include the activation switch.

In at least one embodiment, the system100includes the UV lamp104having UV light emitters108whether or not within the modules106. For example, the UV lamp104can be a single, non-modular assembly that is in communication with the control unit118, which selectively activates and deactivates the UV light emitters108as described herein. In at least one other embodiment, the system100does not include the IR sensor116or the IR source120.

The UV lamps104are configured to emit UV light to disinfect one or more components within the lavatory220, such as the toilet222, the counter224, the sink226, the faucet228, the floor230, one or more walls232, and/or the like. In at least one embodiment, the UV lamps104can be fixed in position. In at least one other embodiment, the UV lamps104can be configured to move. For example, the UV lamps104can be moved between stowed positions and deployed positions.

FIG. 19illustrates a perspective internal view of the lavatory220, according to an embodiment of the present disclosure. Referring toFIGS. 1 and 19, in this embodiment, the UV lamp104includes the IR sensor116that receives the IR light signal119from the IR source120. The IR source120is configured to emit the IR light signal119through an area in which an individual would be if occupying the lavatory220.

The IR sensor116may be aligned with the IR source120to directly receive the IR light signal119from the IR source120. Optionally, the IR source120may be configured to emit the IR light signal119at a reflector, such as a mirror, that reflect the IR light signal119to the IR source120.

The IR sensor116can be mounted directly to the UV lamp104, such as on a housing. In at least one embodiment, the IR sensor116can be secured to a module106. In at least one embodiment, multiple modules106include an IR sensor116. In at least one other embodiment, the IR sensor116is remote from the UV lamp104.

As shown, the IR sensor116can be secured to an end or corner of the UV lamp104. The IR sensor116is configured to receive the IR light signal119either directly from the IR source120or indirectly from the IR source120as reflected from one or more reflectors121. The IR light signal119can be a laser or narrow non-laser optical signal, for example.

As shown, the IR light signal119is configured to extend through a portion of the lavatory220such that a person entering or exiting the room crosses the path of and interrupts the IR light signal119. As the path between the IR source120and the IR sensor116is interrupted, the IR sensor116does not receive the IR light signal119. When the IR sensor116does not receive the IR light signal119, the control unit118does not receive the sensed IR signal122from the IR sensor116. Further, the IR light signal119is directed such that an individual within the lavatory220would interrupt the IR light signal119.

The control unit118operates to ensure that the UV light emitters108are deactivated when an individual is within the lavatory220(or other such room in which the UV lamp104is used). By communicating with the IR sensor116(and optionally, the door sensor242as shown inFIGS. 23 and 24), the control unit118determines whether the room is occupied or unoccupied. If occupied, the control unit118deactivates the UV light emitters108. If unoccupied, the control unit118can activate the UV light emitters108to disinfect one or more components within the room.

FIG. 20illustrates a perspective bottom view of the UV lamp104, according to an embodiment of the present disclosure. Referring toFIGS. 1 and 2, the UV lamp104104includes a housing240having a plurality of UV light emitters108, whether within modules106or not. The IR sensor116is secured to the housing240and is oriented in a direction to receive the IR light signal119.

The control unit118is in communication with the IR sensor116and the UV light emitters108. In at least one embodiment, a door sensor242is also in communication with the control unit118, such as through one or more wired or wireless connections. For example, the door sensor242is a Hall-effect sensor. The door sensor242is configured to detect opening and closing of a door of a room, such as the lavatory220shown inFIGS. 18 and 19. The control unit118selectively activates and deactivates the UV light emitters108based on IR signals (for example reception of such IR signal(s) and lack of reception of such IR signal(s) received from the IR sensor116and door signals (for example, signals indicating that the door is open or closed) received from the door sensor242. Optionally, the control unit118is not in communication with a door sensor.

FIG. 21illustrates a perspective bottom view of the UV lamp104, according to an embodiment of the present disclosure. In this embodiment, the IR sensor116is remotely located from the UV lamp104, and is in communication with the control unit118through one or more wired or wireless connections.

FIG. 22illustrates a perspective bottom view of the UV lamp104, according to an embodiment of the present disclosure. As shown, the housing240can include an extension245. The IR sensor116can be mounted on the extension245.

FIG. 23illustrates a top plan view of the lavatory220, according to an embodiment of the present disclosure.FIG. 24illustrates a perspective internal view of the lavatory220ofFIG. 23. Referring toFIGS. 1 and 19-24, the door sensor242, such as a Hall effect sensor, is configured to cooperate with a magnet260positioned on the door262of the lavatory220to determine when the door262is opened or closed. For example, when the magnet260touches or is in close proximity (such as within 6 inches or less) of the door sensor242, the door sensor242outputs a signal to the control unit118that the door262is closed. In at least one embodiment, the door sensor242can be secured to the housing240of the UV lamp104.

In at least one embodiment, the control unit118deactivates the UV light emitters108of the UV lamp104in response to the IR sensor116not receiving the sensed IR signal122from the IR sensor116. Conversely, the control unit118activates the UV light emitters108to disinfect one or more components within the lavatory220in response to receiving the sensed IR signal122from the IR sensor116and receiving a signal from the door sensor242indicating that the door262is closed. In at least one embodiment, in response to receiving a signal from the door sensor242indicating that the door262is opened, the control unit118deactivates the UV light emitters108, even if the control unit118receives the sensed IR signal122from the IR sensor116.

FIG. 25illustrates a perspective view of the IR sensor116, according to an embodiment of the present disclosure. In at least one embodiment, the IR sensor116includes a socket270that moveably retains a ball272. The ball272retains a sensing element274that is configured to receive and detect an IR light signal. The ball and socket configuration shown inFIG. 25allows the sensing element274to be moved to a desired orientation and alignment so as to receive the IR light signal. Optionally, the IR sensor116may not include a moveable element, such as the ball272moveably retained within the socket270.

Referring toFIGS. 1 and 19-25, in at least one embodiment, the control unit118activates the UV light emitters108in response to determining that the lavatory220(or other such room) is vacated and unoccupied. For example, in response to reception of a signal from the door sensor242that the door262is opened and the sensed IR light signal122for at least one second, followed by reception of a signal from the door sensor242that the door262is closed and the sensed IR light signal122for at least one additional second, the control unit118activates the UV light emitters108for a predetermined sanitizing period (such as 5 seconds). If the control unit118detects that the door262is opened during the sanitizing period, the control unit118immediately deactivates the UV light emitters108.

Further, if the control unit118detects that IR sensor116is not receiving the IR light signal119(such as by not receiving the sensed IR light signal122from the IR sensor), the control unit118deactivates the UV light emitters108. Such an interruption of the IR light signal119triggers a reset event, in which the control unit118may then reactivate the UV light emitters108after determining that the door262has been opened, reception of the sensed IR light signal122from the IR sensor116, the door262is subsequently closed, and further reception of the sensed IR light signal122from the IR sensor116.

FIG. 26illustrates a flow chart of a method of operating a UV lamp, according to an embodiment of the present disclosure. Referring toFIGS. 1 and 19-26, at300, the control unit118determines an opening of the door262, such as via a signal received from the door sensor242. At302, the control unit118determines if the sensed IR light signal122is received from the IR sensor116. If not, the method proceed to304, at which the control unit118deactivates the UV light emitters108, and the method then returns to300.

If, however, the sensed IR light signal122is received from the IR sensor116at302, the control unit118determines if the door262is closed, such as via a signal received from the door sensor242. If the door is not closed, the method returns to304.

If, however, the door262is closed, the control unit118determines if the sensed IR light signal122is received at308. If not, the method returns to304.

If, however, the control unit118determines that the sensed IR light signal122is received at308, the control unit118operates the UV lamp104at310to emit the UV light from the UV light emitters108for a predetermined sanitizing time (such as 3-5 seconds). If, at312, the control unit118determines that the door262is opened during the predetermined sanitizing time, the method returns to304, at which the control unit118immediately deactivates the UV light emitters304.

If, however, the door is not opened during the predetermined sanitizing time at312, the method proceeds from312to314, at which the control unit118operates the UV light emitters108to continue to emit the UV light until an expiration of the predetermined time, at which point the UV light emitters108are deactivated. The process then returns to300.

FIG. 27illustrates a perspective view of a module106, according to an embodiment of the present disclosure. The module106includes a sub-housing400retaining one or more UV light emitters108.
