Abstract: The present invention relates to a control engine configured to control one or more UV-C light sources configured to emit UV-C light in a space. The control engine comprising circuitry configured to execute: a reference image acquiring function configured to construct a reference image using reference radar sensor signals received, at a first time-instance, from a plurality of radar sensors arranged in the space; a probing radar acquiring function configured to construct a probing image using probing radar sensor signals received, at a second time-instance at which the one or more UV-C light sources are inactive, from the plurality of radar sensors, wherein the second time-instance is after the first time-instance; and a control function. The control function is configured to obtain a difference metric between the probing image and the reference image. Upon the difference metric being smaller than a threshold, the control function is configured to activate the one or more UV-C light sources. Upon the difference metric being equal to or above the threshold, the control function is configured to issue an alarm event.

Abstract: The present inventive concept relates to an illumination system and a method for controlling an illumination system configured to illuminate a zone, the illumination system being further configured to serve a plurality of individuals. The method comprising: identifying one or more individuals of the plurality of individuals present in the zone; for each individual present in the zone, obtaining a respective target light profile, each target light profile comprising time-resolved information about circadian stimuli and color temperatures of light that the respective individual is to be exposed to; assigning a priority to each individual of the plurality of individuals present in the zone based on the respective target light profile; determining a proportion of the plurality of individuals present in the zone; and upon the proportion of the plurality of individuals present in the zone is equal to or above a threshold: controlling the illumination system such that a circadian stimulus of light illuminating the zone is higher than a circadian stimulus of the target light profile associated with the individual having a highest assigned priority.
