1. A method of controlling a plurality of lighting units in a space, the method comprising:
receiving an input indicative of an activation of a light scene comprising a plurality of light settings for the plurality of lighting units,
obtaining location information indicative of locations of the plurality of lighting units relative to a location and/or an orientation of a user in the space, the location and/or the orientation of the user being obtained by detecting a current location and/or orientation of the user,
obtaining a circadian rhythm value for each light setting, wherein the circadian rhythm value is indicative of an impact of a respective light spectrum of a respective light setting on the circadian rhythm of a person,
mapping the plurality of light settings onto the plurality of lighting units, wherein each light setting is mapped onto a lighting unit based on the light setting's respective circadian rhythm value and based on the lighting unit's respective location relative to the location and/or orientation of the user,
controlling the plurality of lighting units according to the mapped light settings,
repeatedly detecting the current location and/or orientation of the user, and
remapping the plurality of light settings onto the plurality of lighting units if a difference between a new location and/or orientation of the user and a previous location and/or orientation of the user exceeds a threshold.
