Definitions

  • the present invention relates to luminaire systems and networks of luminaire systems. Particular embodiments relate to luminaire systems and networks of luminaire systems able to disinfect areas.
  • pandemic situation will undoubtedly lead the political and social actors, as well as companies in the public and private sectors, to take novel measures so as to avoid or at least limit the spread of any potential pandemic situation of a similar kind in the future.
  • high-tech companies may play an important role in our societies, through research and development directed to the limitation of the spread of such pandemics.
  • Luminaires especially outdoor luminaires, are present worldwide in nearly every city or at the countryside. Smart luminaires able to work in networks are already present in densely populated areas, such as streets, roads, paths, parks, campuses, train stations, airports, harbors, beaches, etc., of cities around the world, from small towns to metropoles. Such densely populated areas precisely represent the most risky places with respect to propagation of a pandemic situation. Hence, there is an urgent need for developing luminaires which are able to offer smart solutions with respect to epidemic or pandemic situations.
  • the object of embodiments of the invention is to provide a luminaire system able to disinfect areas. More in particular, embodiments of the invention aim at providing a luminaire system able to reduce the risk of propagation of an epidemic or pandemic situation in an autonomous way. Embodiments of the invention also provide a network of such luminaire systems, said network being capable of automatically exchanging information between the luminaire systems and/or with a remote entity and of at least partially autonomously operating to reduce the risk of propagation of an epidemic or pandemic situation, with no need or a reduced need for an external intervention of a user or an operator.
  • a luminaire system comprises a sensing and/or receiving means configured for sensing and/or receiving data related to one or more persons in a vicinity of the luminaire system, a disinfectant means configured for disinfecting at least a portion of the luminaire system and/or the vicinity of the luminaire system, and a control means configured for determining whether there is a need for disinfection based on the sensed or received data, and for triggering the disinfectant means based on a result of the determination of the need for disinfection.
  • Embodiments of the invention are based inter alia on the insight that there is an urgent need to provide smart and autonomous luminaire systems that are able to automatically take or trigger actions in case of an epidemic or pandemic situation, or of any risk of an epidemic or pandemic situation, in order to avoid or limit the spread of the epidemic or pandemic among a population.
  • the sensing and/or receiving means is able to sense or receive data related to the one or more persons at a distance thereof, which results in a safe solution, thereby avoiding any close contact and reducing the risk of infection.
  • the sensing and/or receiving means is able to sense said data while the one or more persons are standing or moving several meters away from the luminaire system.
  • the wording “vicinity” of a luminaire system may be defined as an area at least partially surrounding the luminaire system. Said area may be specified in terms of maximal distances from the luminaire system, i.e., in terms of circles, or circles segments, centered on the luminaire system and of a given maximal radius.
  • control means is able to automatically determine whether there is a need for disinfection based on the sensed or received data, and to trigger the disinfectant means based on a result of the determination of the need for disinfection in an autonomous way, thereby systematically avoiding or limiting the spread of a contagious disease from the vicinity of the luminaire system to remote areas.
  • exemplary embodiments of the luminaire system according to the invention also present the advantage to be able to receive, through the sensing and/or receiving means, data related to the one or more persons in the vicinity of the luminaire system. In this way, data that may be relevant in the context of an epidemic or pandemic situation may be received by the luminaire system without the need to directly sense them.
  • the sensed and/or received data can be data received by the sensing and/or receiving means from different sources, optionally at different moments in time, and which is combined or fused to obtain data related to one or more persons in a vicinity of the luminaire system.
  • Exemplary embodiments relate to an outdoor luminaire system.
  • outdoor luminaire it is meant luminaires which are installed on roads, tunnels, industrial plants, campuses, stadiums, airports, harbors, rail stations, parks, cycle paths, pedestrian paths or in pedestrian zones, for example, and which can be used notably for the lighting of an outdoor area, such as roads and residential areas in the public domain, private parking areas, access roads to private building infrastructures, etc.
  • indoor luminaire it is meant luminaires which are installed inside schools, universities, shopping malls, warehouses, factories, industrial plants, stadiums, airports, harbors, rail stations, tunnels such as pedestrian tunnels, subways, for example, and which can be used notably for the lighting of an indoor area in the public domain, such as schools, airports, rail stations, or in the private domain, such as shopping malls, factories, building infrastructures, etc.

  • specific measures may be taken in order to avoid any such problem. For example, municipality can be involved, receive a warning with the need of disinfection, close the area (manually or remotely or autonomously) and disinfect with UV the targeted areas, for example in the event that the UV radiation is harmful for the citizens or in the event that “stronger” UV radiation must be used to kill all the bacteria/viruses.
