Definitions

  • the invention relates to a method of configuring a lighting system and to a computer program product for executing the method.
  • the invention further relates to a controller for configuring a lighting system.
  • Home and office lighting control systems enable users to control lamps that are distributed throughout a space.
  • a user can assign lighting devices to different areas of the space via a user interface of, for example, a smart device such as a smartphone.
  • a user may, for instance, assign a first lighting device to the living room and assign a second lighting device to the kitchen.
  • This enables a user to set light scenes (lighting control settings for one or more lighting devices) for lighting devices assigned to a certain area.
  • These light scenes may, for example, be activated when a (presence) sensor is triggered, when a light scene is selected via a user interface (e.g. a light switch, a user interface on a smart device, etc.), when a (user-defined) routine is activated, etc.
  • a user interface may be used to manually create a floorplan of a building, wherein a user can indicate where the different rooms are located. This process can be cumbersome. Furthermore, most lighting control software applications do not offer this functionality.
  • U.S. patent application 2014/0354161 Al discloses commissioning of a lighting system.
  • Logical associations into sub-networks may be created based on element locations and/or proximity. Relative proximity of lighting devices may entail detection by light transmission and light sensing.
  • Various system elements within each of rooms are grouped or associated to form a logical sub-network in the respective room. If two rooms are parts of a conference room separated by a moveable partition, the two groups might work together (via a third grouping that encompasses elements in both rooms), e.g. when the partition is open to join the two rooms into one large conference space.
  • the opening of the partition may be recognized by sensing of appropriately modulated light emitted from a lighting device in one room by a sensor in the other room.
  • the lighting devices may be informed of an occupancy state and be turned off if a user is no longer present.
  • the object is achieved by a method of configuring a lighting system, the lighting system comprising a first lighting device located in a first area and a light sensor located in a second area, the method comprising:
  • the sensor data from the light sensor located in the second area is analyzed to determine if the sensor detects light that is emitted by the first lighting device located in the first area.
  • the light output of the first lighting device in the first area is temporally controlled which enables this determination.
  • the light output of the first lighting device may, for example, be modulated such that it comprises an identifier, which may be detected by the light sensor. Alternatively, the light output may be changed at a certain moment in time, which change may be detected by the light sensor. This enables determining that the light emitted by the first lighting device corresponds to the sensor reading of the light sensor.
  • the lighting device and/or its light effect is in the field of view of the light sensor, and that there is a (semi-)transparent boundary (e.g. a window or an opening) between the first area and the second area. In other words, this means that the first area is visible from the second area.
  • the first area e.g. a living room
  • the second area e.g. a garden
  • the lighting system may further comprise a second lighting device located in the second area.
  • the method may further comprise: detecting, by a presence sensor, presence of one or more users in the first and/or second area, and controlling the light output of the first lighting device and the second lighting device as a function of the presence (only) if the first area is visible from the second area.
  • the method may further comprise: detecting, by a presence sensor, presence of one or more users the first and/or the second area, and controlling, if a user is present in one of the first and the second area, the light output of a respective lighting device located in the area wherein the user is located according to a first light setting and the light output of a respective lighting device located in the other area according to a second light setting.
  • a user may be present in the first area, whereupon the first lighting device may be controlled according to a first light setting (e.g. a functional light setting), and the second lighting device may be controlled according to a second light setting (e.g. an ambient light setting).
  • a first light setting e.g. a functional light setting
  • a second light setting e.g. an ambient light setting
  • the second light setting is visible from the first area. This is beneficial because it creates (ambient) light in the second area visible to the user in the first area. If, for example, the first area is not visible from the second area, the lighting device in the other area may be switched off.
  • the second light setting may be based on a previous second light setting of the respective lighting device located in the other area.
  • the previous second light setting may for example be a default light setting, a previous ambient light setting, a user defined light setting, etc.
  • the new light setting which is activated in the other area may be (automatically) derived from a previous (functional) light setting that was already activated in that area.
  • a default (functional) light setting may have been applied to a lighting device in the second area, and upon detecting presence in the first area an ambient light setting is activated in the second area which is based on the default light setting.
  • the ambient light setting may have different brightness (e.g. a lower brightess), saturation (e.g. a higher saturation) or color values compared to the default (functional) light setting.
  • the method may comprise: controlling, if a first user is present in the first area and a second user is present in the second area, the light output of the second lighting device according to a third light setting. If users are present in both areas, the light settings for the areas may be different compared to when only one user is present in one of the first and the second area. For example, both the first and the second lighting device may be controlled according to functional light settings rather than ambient light settings.
  • the method may further comprise: receiving information about types of the first and second areas, and determining light settings for lighting devices in the first and second area based on the type of the respective area. Different types of areas may require different light settings. For instance, a dining room requires different light settings than a garden. It is therefore beneficial to determine/select light settings for the areas based on their type.
  • the method may further comprise repeating, at a second moment in time, the steps of: temporally controlling the light output of the first lighting device, receiving sensor data from the light sensor and analyzing the sensor data.
  • the method may further comprise: determining that, if the sensor data does not correspond to the temporal control of the first lighting device, a light blocking element is located between the first area and the second area at the second moment in time, and storing information indicative of presence of the light blocking element in the memory.
  • these steps of the method may be executed at the second moment in time to determine if the first lighting device (or its light effect) is still in the field of view of the light sensor to determine if a light blocking element (e.g. a closed door, curtains, etc.) is present between the first area and the second area.
  • a light blocking element e.g. a closed door, curtains, etc.
  • the method may further comprise: controlling the light output of the first lighting device (and, optionally, the light output of a second lighting device located in the second area) based on the presence of the light blocking element and, optionally, based on user presence in one of the first and second area.
