APPARATUS FOR CONTROLLING A LIGHTING SYSTEM

The invention refers to an apparatus ( 140 ) for controlling a lighting system ( 100 ) comprising a plurality of lights ( 110, 120, 130 ), wherein the lighting system is adapted to perform a hidden sensing, like radiofrequency sensing, in a sensing region ( 150 ). The apparatus comprises a sensing activity information providing unit ( 141 ) adapted to provide sensing activity information indicative of a hidden sensing activity of the lighting system ( 100 ), a notification mode selection unit ( 142 ) adapted to select a notification mode for notifying a person of the hidden sensing activity, wherein the selection is based on the provided sensing activity information and wherein each notification mode refers to a visual feedback, and a lighting system controlling unit ( 143 ) adapted to control at least two lights of the lighting system based on the selected notification mode to provide the visual feedback. The invention allows to notify a user of a hidden sensing.
