Definitions

  • the mains-powered lighting control device is a mains-powered light switch.
  • the environment 100 is equipped with one or more lighting devices 104 installed or otherwise disposed at different locations throughout the environment 100.
  • a lighting device 104 may refer to any kind of illumination device for illuminating an environment 100 or part of the environment 100 occupied by a user 102, whether providing for example ambient lighting or specific task lighting.
  • Each of the lighting devices 104 may take any of a variety of possible forms, such as a ceiling or wall mounted luminaire, a free standing floor or table lighting device, or a less traditional form such as a lighting device embedded in a surface or an item of furniture.
  • the different lighting devices 104 in the environment 100 need not take the same form as one another. Whatever form it takes, each lighting device 104 comprises at least one lamp (illumination element) and any associated housing, socket and/or support. Examples of suitable lamps include LED-based lamps, or traditional filament bulbs or gas discharge lamps.
  • the beacon receivers 222a, 222b are operatively coupled to the controller 218, 208 respectively.
  • the controllers 218, 208 are configured to control the beacon receivers 222a, 222b respectively.
  • the controller 218 may activate the wireless receiver 222a.
  • each receiving device may transmit the RSSI of the beacon signals to each other device, or to a central lighting bridge 212 or other such central component, via their respective wireless transceiver. Additionally or alternatively, the controller may determine an identifier contained of a specific target device 110 if it is present in the received signals.
  • the localization function 226 may be implemented on a master one of the mains-powered lighting devices 104 or as a distributed function across more than one of the mains-powered lighting devices 104, and/or on a master one of battery-powered devices 108 or as a distributed function across more than one of the battery-powered devices 108.
  • the localization function may be implemented on the target device itself or on the central lighting bridge 212 or on one or more servers, or across a combination of any of the aforementioned devices.
  • the respective controllers 208, 218 of the mains- powered lighting device 104 and the battery-powered device 108 are configured to communicate the monitored beacon signals (or a processed version thereof) to the localization function 226 via any suitable communication channel, e.g.
  • the battery-powered device 108 may adjust the rate at which it (or rather the beacon signal receiver 222a) monitors for beacon signals based on the indication of the beacon signal transmission frequency. If, for example, the transmission frequency is ten transmissions per second, the battery-powered device 108 may scan for beacon signals for a limited time period during which several beacon signals will be transmitted, e.g. 0.5s. The scan duration maybe less than or greater than 0.5s depending on the beacon signal transmission frequency. By minimizing the scanning duration, the power consumption of the battery-powered device 108 can be reduced. Furthermore, it is advantageous for the battery- powered device 108 to scan for beacon signals for longer than the minimal time period since beacon signals can be lost in transmission, e.g. due to interference issues.
  • the beacon functionality of battery-powered devices 108 may be activated in response to a smartphone being detected in the environment 100.
  • the location of the smartphone may be used to control the garden lights which are closest to the smartphone (and therefore the user 102).
  • Battery-operated devices 108 which are assigned to act as beacon receiver, will likely consume more battery charge than a battery-operated device 108 acting as a beacon transmitter ft hence may be advantageous in Figure 3 (upon the mains powered device losing power) to select whether the battery-powered device 108 or the target device 110 acts as beacon receiver based on the remaining battery life of 108 and 110.

Abstract

L'invention concerne un procédé de commande d'un système d'éclairage comprenant au moins un dispositif d'éclairage alimenté par le réseau et au moins un dispositif alimenté par batterie, le dispositif d'éclairage alimenté par le réseau étant configuré pour effectuer une première surveillance de signaux de balise transmis par le dispositif cible ou une première émission de signaux de balise devant être reçus par le dispositif cible pour déterminer un emplacement du dispositif cible. Le procédé consiste à : déterminer, par le dispositif alimenté par batterie, si oui ou non le dispositif d'éclairage alimenté par le réseau est en train d'effectuer ladite première surveillance ou ladite première émission des signaux de balise; et en réponse à la détermination du fait que le dispositif d'éclairage alimenté par le réseau n'est pas en train d'effectuer ladite première surveillance ou ladite première émission des signaux de balise, commander le dispositif alimenté par batterie pour effectuer une seconde surveillance de signaux de balise transmis par le dispositif cible ou une seconde émission de signaux de balise devant être reçus par le dispositif cible pour déterminer un emplacement du dispositif cible.
