    摘要： According to an example embodiment, a method (200) for lighting control in a lighting system (100) is provided. The lighting system (100) comprises a plurality of luminaires (120) for illuminating a space, the plurality of luminaires (120) including a first luminaire (120-m) arranged for illuminating a first location of said space and one or more second luminaires (120-n) that are associated with the first luminaire (120-m) and arranged for illuminating respective second locations of said space. The method (200) comprises: controlling (202) the first luminaire (120-m) to provide light output at a first light intensity in response to detecting occupancy at said first location, wherein the first light intensity is set such that it results in providing at least a first reference light level at said first location; controlling (204) the one or more second luminaires (120-n) to activate their respective light outputs in response to obtaining an indication of the first luminaire having activated its light output while not detecting occupancy at the respective second locations; controlling (206), while not detecting occupancy at the respective second location, the respective second luminaire (120-n) to provide light output at a respective second light intensity, wherein the respective second light intensity is set such that it results in providing at least a second reference light level at the respective second location, where the second reference light level is lower than the first reference light level; and adjusting (208) the second reference light level for the respective second luminaire in dependence of one or more environmental characteristics in said space.

    摘要： A method and devices are provided for controlling the operation of a plurality of devices of a lighting system. First follower relationships are assigned to said plurality of devices; a follower relationship is a software instruction for one device of said lighting system to react upon a message transmitted by another device of said lighting system. A plurality of sensor findings are collected from said devices of said lighting system over a period of time. A sensor finding is a piece of information indicative of a user having been detected by a particular sensor at a particular moment of time. Second follower relationships are determined for said plurality of devices on the basis of said plurality of sensor findings. At least some of said second follower relationships are time-dependent. Said second follower relationships are then assigned to said plurality of devices.
