lighting system to control lighting conditions in a room to affect a person's circadian rhythm, method of controlling lighting conditions in a room, hospital room, computer program product, record carrier, and use of Lighting System The present invention relates to a lighting system (100) and a method of controlling the lighting conditions in a room (r). The lighting system (100) comprises a controller (101) for controlling internal light sources (121, 122) and at least one driver (31, 141) for changing the amount of external light entering room (r). In addition, at least one sensor (111, 112, 131, 141) is provided to detect a parameter relative to the desired or actual lighting level of the room (r). In this way, it is possible to control the illumination of the room (r) according to a predetermined schedule, particularly with a circadian rhythm that can reduce delirium in a patient (p). the actuator may for example comprise a means (141) for closing or opening curtains (142) in front of a window (w). 1/1
