Definitions

  • the example and non-limiting embodiments of the present invention relate to wirelessly connecting a mobile device to a desired one of a plurality of luminaires for exchanging information that enables monitoring and/or adjusting operational parameters of the desired luminaire via the mobile device.
  • Many modern luminaires enable monitoring and/or adjustment of at least some of their operational parameters e.g. during installation, during maintenance and/or even during their normal operation. Monitoring and/or adjustment may be carried out via a control unit provided in the luminaire and these operational parameters may include settings related aspects such as light intensity level, dimming behavior, response to sensor signals (such as light sensors and/or presence sensors), color temperature, etc.
  • Access to the adjustable parameters of a luminaire may be provided by a mobile device such as a mobile phone that communicates with a control unit of the luminaire over a wireless channel using a suitable short-range wireless technology such as Bluetooth (BT).

  • the approach outlined above enables finding the desired one among a plurality of luminaires installed in locations that difficult or to reach for visual inspection and/or without need to inspect e.g. identification labels affixed to luminaires. Moreover, this approach also quite apparently enables a fast access to the operating parameters of a single luminaire in a space. On the other hand, in a scenario where there is a plurality of luminaires installed in the space, the above-outlined approach may involve a significant delay in identifying the desired one of the plurality of luminaires using a trial-and-error procedure.

  • the control means in the mobile device 130 may be provided, for example, by a processor and a program code stored in a memory, where the program code is arranged to cause the mobile device 130 to implement operations described in the forgoing by various examples that refer to the method 200a when the program code executed by the processor.
  • the mobile device 130 may comprise, for example, a general purpose mobile device such as a mobile phone, a tablet computer, a laptop computer, etc. arranged to carry out the operations described via examples provided in the foregoing.
  • the mobile device 130 may comprise a special-purpose device that serves as a 'remote controller' for monitoring and/or adjusting operating parameters of the luminaires 110.
  • the control means in the luminaire 110-n may be provided, for example, by a processor and a program code stored in a memory, where the program code is arranged to cause the luminaire 110-n to implement operations described in the forgoing by various examples that refer to the method 200b when the program code executed by the processor.
  • control means may be provided as part of the driver device of the luminaire 110-n.
