Definitions

  • the invention relates to a system for controlling a lighting device to render UV disinfection light.
  • the invention further relates to a method of controlling a lighting device to render UV disinfection light.
  • the invention also relates to a computer program product enabling a computer system to perform such a method.
  • UVC light 200-290 nm
  • the majority of UVC light sources include part of the spectrum around 250nm which is dangerous for people. As a result, these light sources can only be used when people are either not present or when it is possible to avoid light falling on human skin and eyes.
  • the use of safer far-UV and 405 nm is also being explored, especially for the consumer market.
  • US 2018/0296711 Al discloses a room decontamination system that uses UV radiation to perform a decontamination operation in a room.
  • a controller may determine whether safe conditions for decontamination exist and initiate a decontamination operation on the basis of whether they exist. Determination of safe conditions for decontamination may be based on light actuation detection and/or sensor data, which may include presence detector data and door sensor data.
  • a system for controlling a lighting device to render UV disinfection light comprises at least one output interface and at least one processor configured to analyze at least one visible light routine having a routine start time and/or a routine end time, said at least one visible light routine automatically controlling at least one further lighting device to render visible light at a first scheduled time when activated, determine, based on results of said analysis, a disinfection routine for automatically controlling said lighting device to render said UV disinfection light at a second scheduled time, and activate and/or recommend said disinfection routine via said at least one output interface.
  • UV radiation devices are part of a smart home lighting system, it becomes possible to determine the disinfection routine based on an analysis of at least one visible light routine and prevent accidental exposure to UV radiation without the use of presence sensors. This may not only be beneficial when UVC is used but it may also beneficial to let safe 405 nm light sources be active when no one is present, due to a specific blue light that might be uncomfortable for the user.
  • Said at least one processor may be configured to analyze said at least one visible light routine by analyzing one or more already activated visible light routines. By analyzing the already activated visible light routines, spatial areas where persons are likely present may be identified and avoided as much as possible.
  • Said at least one processor may be configured to determine, as part of said analysis, at least one time associated with said at least one visible light routine and determine said disinfection routine based on said at least one time.
  • the at least one time may comprise a start time and/or an end time of the at least one visible light routine, for example.
  • Said at least one processor may be configured to determine said second scheduled time such that said second scheduled time does not overlap with said first scheduled time, e.g. based on the at least one time associated with the at least one visible light routine.
  • Said at least one processor may be configured to determine, as part of said analysis, at least one spatial area associated with said at least one visible light routine and determine said disinfection routine further based on said at least one spatial area.
  • a spatial area may be determined at the same time as said at least one visible light routine in a different spatial area or at a different time as said at least one visible light routine in the at least one spatial area associated with the at least one visible light routine, for example.
  • Said at least one processor may be configured to determine a routine start time, a routine end time, and an associated spatial area for each respective light routine of said at least one visible light routine and determine said disinfection routine such that said lighting device is not controlled to render UV disinfection light between said routine start time and said routine end time in said associated spatial area of each respective light routine.
  • said at least one visible light routine may comprise a visible light routine in a bathroom which ends at a first end time and said at least one processor may be configured to determine said disinfection routine in said bathroom starting a predetermined time after said first end time.
  • Said predetermined time may be zero minutes, five minutes, or fifteen minutes, for example.
  • a room may be considered to be a bathroom if it comprises at least one of a shower, a bath, a washbasin and/or a toilet.
  • Said at least one processor may be configured to determine, as part of said analysis, a light routine type for each of said at least one visible light routine and determine said disinfection routine further based on said at least one light routine type.
  • said at least one visible light routine may comprise a fall asleep routine which ends at a second end time and said at least one processor may be configured to determine said disinfection routine in one or more spatial areas other than a bedroom a predetermined time after said second end time.
  • Said at least one processor may be configured to determine a home layout and determine said disinfection routine based on said home layout. For example, if the home has an open kitchen connected to the living room, it is beneficial not to activate disinfection light in the kitchen during a time when it is likely, based on the visible light routine(s), that a person is present in the living room.
  • Said at least one processor may be configured to receive a signal indicative of user input, said user input defining a new visible light routine, and analyze said at least one visible light routine by analyzing said new visible light routine upon receiving said signal indicative of said user input. For example, if a user defines a new visible light routine in the bathroom, a disinfection routine may be recommended and/or activated which starts after the end time of the new visible light routine in the bathroom. Both said new visible light routine and already activated visible light routines may be analyzed. Alternatively, only said new visible light routine may be analyzed. The latter may be beneficial in situations where it is unlikely that someone will be present in the spatial area specified in the new visible light routine after the end time specified in the new visible light routine.
  • Said at least one processor may be configured to receive a signal indicative of further user input, said further user input requesting a new disinfection routine to be created, and create said new disinfection routine upon receiving said signal indicative of said further user input by activating said determined disinfection routine.
  • This allows the system to recommend, for example, a start time, end time, and spatial area for the new disinfection routine that the user wants to create, and to activate this new disinfection routine, e.g. if acceptable to the user.
  • Said at least one processor may be configured to detect said lighting device being added to a lighting system, one or more visible light routines being updated, and/or a change in a user’s daily patterns, and analyze said at least one visible light routine, determine said disinfection routine, and activate or recommend said disinfection routine upon detecting said lighting device being added to said lighting system, said one or more visible light routines being updated, and/or said change in said user’s daily patterns. This may be used to ensure that a new UV lighting device is immediately put into use and/or that the disinfection routine(s) are up to date and avoid spatial areas where persons are likely present.
  • Said at least one processor may be configured to receive one or more signals indicative of historic presence data and determine said disinfection routine further based on said historic presence data and/or determine a recommended visible light routine based on said historic presence data. If there are lighting devices that are still switched on manually or switched on automatically in response to a sensor event, the historic presence data may be used to improve the determination of disinfection routine and/or to determine one or more visible light routines to be recommended and/or activated.
  • a method of controlling a lighting device to render UV disinfection light comprises analyzing at least one visible light routine having a routine start time and/or a routine end time, said at least one visible light routine automatically controlling at least one further lighting device to render visible light at a first scheduled time when activated, determining, based on results of said analysis, a disinfection routine for automatically controlling said lighting device to render said UV disinfection light at a second scheduled time, and activating and/or recommending said disinfection routine via said at least one output interface.
  • Said method may be performed by software running on a programmable device. This software may be provided as a computer program product.
  • a computer program for carrying out the methods described herein, as well as a non-transitory computer readable storage-medium storing the computer program are provided.
  • a computer program may, for example, be downloaded by or uploaded to an existing device or be stored upon manufacturing of these systems.
  • a non-transitory computer-readable storage medium stores at least one software code portion, the software code portion, when executed or processed by a computer, being configured to perform executable operations for controlling a lighting device to render UV disinfection light.
  • the executable operations comprise analyzing at least one visible light routine, said at least one visible light routine automatically controlling at least one further lighting device to render visible light at a first scheduled time when activated, determining, based on results of said analysis, a disinfection routine for automatically controlling said lighting device to render said UV disinfection light at a second scheduled time, and activating and/or recommending said disinfection routine via said at least one output interface.
