Description

Space for an aircraft, aircraft with the space, and method for disinfecting a surface of a space by means of a disinfection device

The invention relates to a space for an aircraft and an aircraft with the space. The invention also relates to a disinfection device for use in a space area of an aircraft for disinfecting at least one surface of the space area using UVC radiation and a method for operating a disinfection device, the disinfection device being designed to disinfect at least one surface of a space area of an aircraft.

Washrooms in aircraft are usually cleaned manually by cleaning personnel after the aircraft has flown. To avoid the formation of germs and to kill pathogens, surfaces with disinfecting cleaning agents can be used. It is also already known to irradiate surfaces and objects with UVC radiation for disinfection.

For example, the document DE 102005 027 859 A1 describes a method with devices and arrangements to prevent the formation of biofilms on the walls of containers, objects, surfaces, etc. in hygiene-relevant dry and wet areas, with short-wave UVC radiation from a UVC radiation source through a UVC-conducting matrix is guided and is partly radiated directly by reflection through the surface towards the transporting and surface-wetting medium.

The publication WO 2004/108174 A1 discloses a ventilation system for an aircraft cabin and a UVC radiation unit for irradiating the air circulating in the ventilation system with ultraviolet radiation for the purpose of sterilizing the air.

The object of the invention is to provide an improved solution for disinfecting surfaces in a space in an aircraft. This task is done by a Space for an aircraft with the features of claim 1, solved by an aircraft with the space according to claim 10 and by a method for operating a disinfection device with the features of claim 11. Preferred or advantageous embodiments of the invention result from the dependent claims, the following description and/or from the attached figures.

An area of space for an aircraft is proposed. For example, the spatial area is designed as a cabin, in particular as a passenger cabin, as a galley, gailey, or as a washroom, lavatory.

The room area includes a disinfection device. The disinfection device is designed to disinfect at least one surface, preferably several surfaces, of the spatial area. The surfaces are preferably possible contact surfaces for passengers and crew members. The surfaces can be arranged, for example, on a spatial structure of the spatial area, which includes, for example, floor, ceiling and walls as well as items of equipment and/or furniture. Alternatively or optionally in addition, the surfaces can be arranged on sanitary facilities, such as toilets, wash basins or sinks, and on furniture, compartments, seats, etc. The surfaces are optionally arranged in wet and dry areas of the room area.

The disinfection device is designed to disinfect the surfaces of the spatial area by means of UVC radiation, preferably by means of short-wave UVC radiation, in particular by means of ultraviolet radiation. A wavelength of the UVC radiation is in particular between 280 nanometers and 100 nanometers. The disinfection device for disinfecting the surfaces is preferably arranged within the spatial area or it is arranged in such a way that it can irradiate and disinfect the surfaces with the UVC radiation. Disinfection using UVC radiation can prevent the formation of germs and kill pathogens on the surfaces. Thus, infection of persons with a disease upon contact with the surfaces can be prevented. In particular, disinfection using UVC radiation can advantageously limit the occurrence of an infection, for example when there is a prevailing wave of infection and/or a pandemic.

It is advantageous that cleaning personnel and/or flight personnel, in particular during a flight, are not required to disinfect the surfaces of the space manually. Rather, the disinfection device advantageously ensures independent and preferred regular disinfection of surfaces. Thus, the cleaning staff and/or the flight crew can be relieved and devote themselves to other important tasks in flight operations.

The disinfection device has a lighting device for generating and emitting the UVC radiation. The lighting device preferably comprises at least one luminous tube, the luminous tube being designed to generate and emit the UVC radiation. The lighting device, in particular the at least one fluorescent tube, is preferably designed to emit UVC radiation with a wavelength of preferably up to 270 nanometers, in particular up to 260 nanometers, in particular up to 250 nanometers and/or 254 nanometers. The lighting device is optionally designed to irradiate the surfaces with an intensity of at least 50 J/m² (joules per square meter), preferably at least 100 J/m² and/or at most 250 J/m². A radiometric flow and/or current of the UVC radiation is, for example, at least 3.5 watts, preferably at least 4 watts, in particular at least 5 watts and/or 4.2 watts. A period of time in which the surfaces are irradiated with the UVC radiation for disinfection by means of the lighting device is at least 20 seconds, preferably at least 30 seconds, in particular at least 40 seconds and/or at most 60 seconds.

The lighting device is portable, in particular mobile and/or portable. This applies in particular to a state in which the lighting device is not actively operated, that is to say in which it does not light up. The lighting device is therefore a portable device in its inactive state and can therefore be carried by a person on board an aircraft if required. In the inactive state, the lighting device can be decoupled from the surface or spatial structure and is then a separate, freely movable device. The lighting device preferably has manageable dimensions for this, e.g. dimensions of a maximum of 400 x 400 x 300 millimeters, preferably of a maximum of 350 x 350 x 250 millimeters, in particular of a maximum of 300 x 250 x 150 millimeters and/or of 300 x 230 x 100 millimeters. The lighting device preferably has a relatively low weight of at most 5 kilograms, preferably at most 3.5 kilograms, in particular at most 2 kilograms. In particular, due to the handy dimensions and the relatively low weight, the lighting device can be easily and comfortably transported into and out of the spatial area, in particular portable.

For example, the disinfection device includes a stowage device in which the lighting device, for example, in an inactive state, especially when the Lighting device has no stand-by state and / or generates and emits no UVC radiation, can be stowed away. The stowage device is designed, for example, as a suitcase, trolley or as a transportable, for example, rollable and/or movable compartment and/or storage compartment of the spatial area. In particular, the lighting device can be accommodated safely and protected from damage in the stowage device. In particular, the transport of the lighting device into the spatial area and/or out of it again can be facilitated by stowing the lighting device in the stowage device.

In an active state, in particular in a stand-by state and/or during and/or during the generation and emission of the UVC radiation, the lighting device is arranged in a fixed position and/or stationary. Stationary here means opposite to the surface to be illuminated and thus to be disinfected. In particular, the lighting device is also arranged in a stationary manner in relation to the aircraft cabin or its device. The lighting device is thus fixed or integrated in the aircraft in the active state. Thus, in particular, the same surfaces of the room area can be disinfected with each disinfection.

According to the invention, the disinfection device comprises a fastening device. In the active state, the lighting device is stationary relative to the surface and is arranged on the spatial structure by means of the fastening device. The lighting device is fixed to the spatial structure with the fastening device. The fastening device is designed for fastening the lighting device to the spatial structure of the spatial area so that it can be detached without damage. The lighting device is/is detachably connected to the fastening device and/or detachably coupled to the fastening device. For example, the lighting device can be releasably connected to the fastening device in a positive and/or non-positive manner. The fastening device thus acts as an interface between the lighting device and the spatial structure or as an adapter that establishes the connection between the lighting device and the spatial structure. In an inactive state, the lighting device can be decoupled from the fastening device and is then a separate, freely movable device, i.e. no longer connected to the fastening device and thus to the spatial structure. In the decoupled state, the device can therefore be carried by one person in particular and can be positioned on a further fastening device in the aircraft or also carried from board.

In one possible implementation of the invention, the lighting device can be detached and/or detached from the fastening device without tools and/or without damage be removed. In particular, the lighting device can be easily and quickly connected to the fastening device and detached from it again.

The lighting device is preferably removed from the fastening device without being damaged when it is inactive and/or in order to stow it in the stowage device. This has the advantage that the lighting device is only connected to the fastening device and fastened to the spatial structure when required, in particular only when the surfaces are/are to be disinfected by means of UVC radiation. In the inactive state, in particular when not in use, the lighting device can be detached or removed from the fastening device and/or safely stowed away in the stowage device. In this way, in particular, unwanted manipulation and damage to the lighting device caused thereby can be prevented. Furthermore, a risk of injury from the UVC radiation for persons, e.g. for passengers of the aircraft and/or for the crew on board, in the vicinity of the disinfection device and/or in the room area can be avoided.

The fastening device is designed, for example, as a clamping device. The lighting device can preferably be clamped in the clamping device so that it is held and/or carried by the clamping device. By clamping the lighting device, it is securely connected to the clamping device, so that the lighting device cannot unintentionally become detached from it, e.g. during manipulation, flight movements and/or turbulence of the aircraft.

Alternatively, the fastening device is designed as an adapter device, e.g. as an adapter plate. The adapter device and the lighting device preferably include corresponding snap-in interfaces for the detachable coupling of the lighting device to the adapter device.

In a preferred constructional embodiment of the invention, the fastening device is fastened to the spatial structure of the spatial area, eg to a wall, a door, a floor, a ceiling or to a piece of furniture and/or furniture in the spatial area. Preferably, the fastening device cannot be detached from the spatial structure without being damaged. In particular, the fastening device is permanently fastened to the spatial structure. For example, the fastening device is materially connected to the spatial structure, in particular glued or welded to it. Alternatively, a positive and/or non-positive attachment of the attachment device to the spatial structure is possible. The fastening device preferably has dimensions that are smaller than the dimensions of the lighting device. Thus, the fastening device is preferably not visible when the lighting device is fastened to and/or coupled to it. For example, the fastening device has dimensions of a maximum of 380×380×10 millimeters, preferably a maximum of 250×250×8 millimeters, in particular 120×120×3 millimeters and/or 200×200×6 millimeters.

It is particularly preferred within the scope of the invention that the fastening device is arranged on the spatial structure below an average viewing height for humans. For example, the fastening device is fastened to the spatial structure below a height measured from the floor of 170 cm, preferably below 160 cm, in particular below 150 cm. This has the advantage that direct eye contact and/or looking directly into the fluorescent tube of the lighting device can be avoided. As a result, injuries to the eyes of people who enter or stay in the spatial area during operation of the lighting device can be reduced or prevented.

In a possible structural realization of the invention, the disinfection device has a rechargeable energy source. The energy source is, for example, at least one rechargeable battery and/or at least one accumulator, in particular an NiMh battery pack. The disinfection device can thus be operated independently of an on-board network of the aircraft. The rechargeable energy source can be integrated in the fastening device and/or in the lighting device. The lighting device preferably has a connection by means of which the energy source can be charged. The energy source preferably has a capacity which is sufficient for carrying out several disinfections of the surfaces of the room area, for example at least 15 disinfections, preferably at least 20 disinfections, in particular at least 25 disinfections.

In a further possible structural realization of the invention, the disinfection device has a timer. The timer is preferably designed to activate and/or deactivate the disinfection device, in particular the lighting device in the stand-by state, at a specific point in time and/or after a specific period of time. The disinfection device, in particular the lighting device, can preferably be switched on for the first time, in particular put into the stand-by state. For this purpose, the lighting device preferably has a switch-on device, for example an actuating button or actuating switch. Preferably, the timer starts generating and Emission of the UVC radiation only after a certain time after the activation of the switch-on device, so that the person who activated the switch-on device is given enough time to leave the room area. Thus, the person can be protected from UVC radiation. By providing the timer, independent and regular disinfection of the surfaces of the room area can advantageously take place. In particular, a further action by the cleaning personnel and/or on-board personnel for regular activation and/or deactivation of the lighting device after it is switched on for the first time is not necessary.

In a preferred embodiment of the invention, the disinfection device has a protective device. The protective device is designed to protect people in the vicinity of the disinfection device, in particular in the spatial area and/or in other spatial areas of the aircraft, from UVC radiation. This is beneficial as UVC radiation can be harmful to people's skin and eyes and can cause injury.

Within the scope of the invention, it is preferred that the protective device comprises at least one panel. The panel is preferably provided on the lighting device to cover the fluorescent tube. For example, the aperture can be opened when the lighting device is active in order to emit the UVC radiation onto the surfaces. In particular, when the lighting device is inactive, e.g. when the lighting device has been removed from the fastening device and/or is stowed in the stowage device, the cover can be closed in order to protect the at least one fluorescent tube from damage and/or to protect the people in the vicinity of the lighting device and /or to protect against UVC radiation when handling the lighting device. The aperture can be opened and/or closed in particular manually or automatically, for example by a suitable actuator.

In the context of the invention, it is also preferred that the protective device includes a signaling device. The signaling device is preferably designed to emit an optical and/or acoustic warning signal when the lighting device is active, in particular when the lighting device emits the UVC radiation. The signaling device can be arranged or integrated on the fastening device or on the lighting device. The signaling device that emits the optical warning signal can be, for example, at least one light-emitting diode or another light source. The optical warning signal is in particular a continuous or flashing warning light, for example in the signal color red. The signaling device that emits the acoustic warning signal can be a loudspeaker, for example. The acoustic warning signal is in particular a warning tone or a warning noise, for example an easily audible whistle. It is advantageous that people who approach or enter the room area are informed that the disinfection device is active and the UVC radiation is being emitted. In particular, people are warned that they are exposed to UVC radiation when entering the room area and/or approaching the disinfection device. This can advantageously prevent people from being injured by the UVC radiation.

In one possible implementation of the invention, the protective device has a proximity switch. The proximity initiator is preferably designed to deactivate the lighting device when a person approaches the disinfection device and/or enters the room area. The proximity initiator preferably includes a sensor device. The sensor device is preferably designed to detect a person approaching the disinfection device as approach data. For this purpose, the sensor device is designed, for example, as a motion sensor, which can detect a movement of the person and/or a door of the room area. Optionally, the proximity initiator additionally includes an actuator which deactivates the lighting device on the basis of the proximity data. It is advantageous that the lighting device is automatically deactivated when the person approaches it. This advantageously prevents injury to the approaching person from the UVC radiation.

Within the scope of the invention it is possible for the disinfection device to have a control device. The control device is designed to control, in particular to activate and deactivate, the timer and/or the protective device, e.g. the signaling device and/or the proximity switch. Optionally, the actuator for opening and closing the panel can be controlled by the control device.

A further object of the invention is an aircraft with the space area according to the previous description and/or according to one of claims 1 to 9.

A disinfection device for use in a room area of an aircraft is designed to disinfect the surfaces of the room area using UVC radiation. The disinfection device has a lighting device which is designed to generate and emit the UVC radiation. The lighting device is designed to be portable, mobile and/or portable. Furthermore, the lighting device is in arranged stationary and/or stationary relative to the surface in an active state. The spatial area in which the disinfection device is used is preferably designed according to the previous description and/or according to one of claims 1 to 9.

A method for operating a disinfection device in a space area for an aircraft forms a further subject matter of the invention. The disinfection device is designed to disinfect at least one surface of the room area using UVC radiation. The disinfection device is preferably designed according to the previous description and/or according to claim 11.

The disinfection device includes a lighting device that generates and emits the UVC radiation after the disinfection device has been put into operation, e.g. activated. The disinfection device has a fastening device which is designed in particular to fasten the lighting device to a spatial structure of the spatial region so that it can be detached without damage. Within the scope of the method, the lighting device is arranged in an active state, in particular when it is in a stand-by state and/or generates and emits the UVC radiation, in a fixed position and/or stationary on the fastening device. As part of the method, the lighting device is removed from the fastening device in an inactive state.

For example, the lighting device is connected to the fastening device before the activation of the disinfection device, in particular for its commissioning, and is thus arranged in a stationary manner. The lighting device and the fastening device are preferably connected to one another in a detachable manner without damage.

In particular, the lighting device is removed from the fastening device without damage after the disinfection device has been deactivated, e.g. when not in use. Optionally, the lighting device is stowed away in a storage device of the disinfection device after it has been removed from the fastening device.

Within the scope of the method, the UVC radiation is preferably generated and emitted after the activation of the disinfection device, in particular in the active state, with the surface of the spatial area being disinfected by the UVC radiation. Optionally, as part of the method, at least one screen, which covers at least one fluorescent tube of the lighting device, is opened before and/or during commissioning and/or activation of the lighting device, in particular in order to be able to radiate the UVC radiation onto the at least one surface using the fluorescent tube. Optionally, in addition, the at least one screen is closed again after the end of the disinfection and/or when the disinfection device is inactive, in particular when the lighting device is inactive.

An optical and/or acoustic signal is preferably emitted as part of the method when the disinfection device is active, in particular when the lighting device is in the active state, in particular during the generation and emission of the UVC radiation. In particular, the disinfection device is deactivated as part of the method and/or the emission of the UVC radiation is stopped when a person approaches the disinfection device and/or when there is movement in the spatial area.

Corresponding or identical parts are provided with the same reference symbols in the figures.

FIG. 1 shows a spatial area 1 for an aircraft in a perspective view. The room area 1 is designed as a washroom and/or as a lavatory educated. The spatial area 1 comprises a spatial structure 2 which comprises side walls, a door and a floor which delimit the spatial area 1 at least in sections.

The spatial area 1 includes a disinfection device 3. The disinfection device 3 is designed to carry out a disinfection of surfaces 4 of the spatial area 1 by means of UVC radiation 5. In particular, the surfaces 4 can be sterilized by the disinfection and freed from pathogens, for example viruses and bacteria. The surfaces 4 are wet and dry areas of the spatial area 1. They are arranged in sections on the spatial structure 2, on a toilet, a sink, on furniture and/or on storage areas etc. of the spatial area 1.

The disinfection device 3 has a lighting device 6 . The lighting device 6 is shown in a perspective plan view from above in FIG. 2 and in a perspective plan view from below in FIG.

The lighting device 6 has at least one fluorescent tube 8 , for example two fluorescent tubes 8 . The fluorescent tubes 8 are designed to generate the UVC radiation 5 (FIG. 1). The lighting device 6 can irradiate the surfaces 4 with the UVC radiation 5 with a strength of at least 50 J/m², preferably at least 100 J/m² and/or at most 250 J/m². The UVC radiation 5 has a wavelength of preferably up to 270 nanometers, in particular up to 260 nanometers, in particular up to 250 nanometers and/or 254 nanometers. A radiometric flow and/or current of the UVC radiation is, for example, at least 3.5 watts, preferably at least 4 watts, in particular at least 5 watts and/or 4.2 watts.

The lighting device 6 comprises a substantially L-shaped receiving housing 9. The light tubes 8 are received in the receiving housing 9. The receiving housing 9 can have at least one movable panel for covering the luminous tubes 8, in particular when the luminous device 8 is inactive. When the lighting device 6 is active, the diaphragm is opened so that the UVC radiation 5 can be emitted. The panel can be designed, for example, as a blind or as a roller shutter.

The lighting device 6 has a relatively low weight of a maximum of 5 kilograms, preferably a maximum of 3.5 kilograms, in particular a maximum of 2 kilograms. The receiving housing 9 has compact and/or handy dimensions of a maximum of 400 x 400 x 300 millimeters, preferably of a maximum of 350 x 350 x 250 millimeters, in particular of a maximum of 300 x 250 x 150 millimeters and/or of 300 x 230 x 100 millimeters. As a result, the receiving housing 9 and thus the lighting device 6 are designed to be mobile and/or portable.

The disinfection device 3 comprises a stowage device 11 (FIG. 5e) in which the lighting device 6 can be stowed away when it is inactive. The stowage device 11 is embodied, for example, as a suitcase, trolley or as a mobile compartment or compartment of the spatial area 1, for example.

As shown schematically in FIG. 2, the lighting device 6 has a rechargeable energy source 15, in particular an accumulator, for example an accumulator pack. The energy source 15 is integrated in the receiving housing 9 . A charging socket 10 is arranged on the receiving housing 9, via which the energy source 15 can be charged by connecting a cable with a suitable plug. The energy source 15 has a capacity by means of which several disinfections of the surfaces 4, for example at least 15 disinfections, preferably at least 20 disinfections, in particular at least 25 disinfections, can take place, preferably at time intervals from one another.

The disinfection device 3 has a fastening device 7, which is shown in FIG. 4 in a plan view from the front. The fastening device 7 is designed as an adapter plate with latching devices 12 .

According to FIGS. 1, 5a and 5d, the fastening device 7 is materially fastened to the spatial structure 2, in particular to one of the side walls of the spatial area 1, for example glued to it. The fastening device 7 is fastened below a normal viewing height of a person, measured for example from the floor of the spatial area 1, at a maximum height of 170 cm, preferably a maximum height of 160 cm, in particular a maximum height of 150 cm.

As shown in FIG. 3, the receiving housing 9 of the lighting device 6 has counter-locking devices 13 which correspond to the locking devices 12 of the adapter plate. By means of the latching devices 12 and the counter-latching devices 13, the lighting device 6 can be releasably coupled to the fastening device 7, in particular positively and/or non-positively connected to the fastening device 7 and removed from it again without damage. To assemble the disinfection device 3, in particular before it is put into operation and/or activated, the fastening device 7 and the lighting device 6 as can be seen from FIG. 5b, detachably coupled to one another by the counter-locking devices 13 being locked in the locking devices 12. In an active state, ie when the lighting device 6 is in a stand-by state and/or generates and emits the UVC radiation, it is connected to the fastening device 7 and held stationary and/or stationary relative to the surface 4 .

A switch-on device 14 is arranged on the receiving housing 9, which is designed to switch on the disinfection device 3, in particular the lighting device 6, and to switch it to the stand-by state. The disinfection device 3 can also be switched off again by means of the switch-on device 14 . Switching on takes place in particular manually, e.g. for the first time after attachment with the attachment device 7. By actuating the switch-on device 14, the disinfection device 3, in particular the lighting device 6, is switched to the stand-by state. It is possible for it to be switched on, in particular activated, for the first time after it has been coupled to the adapter plate in order to generate and emit the UVC radiation 5 .

As shown schematically in FIG. 2, the disinfection device 3 has a timer 16, by means of which the lighting device 6 can be activated at a certain point in time and/or after a certain period of time to generate and emit the UVC radiation 5. The timer 16 is designed to activate the disinfection device 3 only after a certain period of time after the activation device 14 has been actuated. This gives the person who actuates the switch-on device 14 enough time to leave the room area 1 before the generation and emission of the UVC radiation 5 starts. In the stand-by state, the lighting device 6 can be activated regularly by the timer 16 for repeated disinfection of the surfaces 4. The disinfection device 3 includes a control device for controlling the timer 16.

The disinfection device 3 has a protective device 19 for protecting people in the vicinity of the disinfection device 3 . The protective device 19 includes the screen, by means of which the fluorescent tube 8 can be blinded to protect people from UVC radiation and optionally to protect the fluorescent tube 8 from damage.

The protective device 19 has a proximity switch 17 . The proximity initiator 17 comprises a proximity and/or movement sensor for detecting the approach of the person(s) and/or a movement in the spatial area 1, eg a opening movement of the door. The proximity initiator 17 is designed to deactivate the disinfection device 3, in particular the lighting device 6, when one or more people approach and/or when there is a movement in the spatial area 1 to the active disinfection device 3. In particular, the proximity initiator 17 deactivates the generation and emission of the UVC radiation 5 when the person(s) approaches or there is movement in the spatial area 1 in order to prevent the person(s) from being injured by the UVX radiation.

The protective device 19 comprises a signaling device 18. The signaling device 18 is designed to emit an optical signal, e.g. a warning light and/or flashing light. The signaling device 18 is also designed to emit an acoustic signal, e.g. a warning tone or warning noise. In particular, the signaling device 18 emits the optical and/or acoustic signal when the disinfection device 3 is active, in particular when the UVC radiation 4 is generated and emitted. In this way, people in the vicinity of the disinfection device 3 who are, for example, in front of, next to or in the room area 1 can be warned against entering the room area 1, approaching the disinfection device 3 and/or exposing themselves to the UVC radiation 5. The control device is designed to activate the protective device 19 .

Method steps for operating the disinfection device 3 are shown in FIGS. 5a to 5e. According to FIG. 5a, the fastening device 7 is fastened to the three-dimensional structure 2 and is thus provided and fixed for fastening the lighting device 6 to the three-dimensional structure 2 so that it can be detached without damage.

According to FIG. 5b, the lighting device 6 is detachably coupled to the fastening device 7 and is thereby arranged in a fixed and/or stationary manner in relation to the surface 4. The switch-on device 14 is actuated in order to switch on the disinfection device 3, in particular the lighting device 6, and/or to put it into the stand-by state.

According to FIG. 5c, the UVC radiation 5 is generated when the timer 16 is switched on or when it is switched on, and is radiated onto the surface 4 to disinfect it. The surface 4 is irradiated with the UVC radiation 5 for at least 20 seconds, preferably at least 30 seconds, in particular at least 40 seconds and/or at most 60 seconds. Then the disinfection is finished. After a certain period of time has elapsed or at a certain point in time, the timer 16 activates one or more renewed disinfections of the surface 4 by emitting the UVC radiation. The optical and/or acoustic warning signal is emitted while the UVC radiation is being emitted. During the radiation, the spatial area 1 is monitored to determine whether a person is approaching and/or whether there is movement in the spatial area 1 . As soon as the approach and/or movement is detected, the disinfection device 3 is deactivated and the emission of the UVC radiation is stopped or interrupted for a certain time.

After completion of the disinfection, in particular after the deactivation of the disinfection device 3, the lighting device 6 is detached or decoupled from the fastening device 7 according to FIG. 5d, so that the lighting device 6 is now a separate, portable device. According to FIG. 5e, the lighting device 6 is stowed in the stowage device 11. FIG. The energy source 15 of the disinfection device 3 can be recharged in the stowage device 11 or outside of it, so that the surfaces 4 of the spatial area 1 can be disinfected again.
