    • The present invention relates to a phototherapy system comprising an LED carrier (10) for being arranged on or under a subject (100), a set (12; 24, 26; 36) of LEDs (13; 23, 25; 33, 35), wherein at least a first subset (12; 24; 34) of LEDs (13; 23; 33) of said set is arranged in or at the LED carrier (10), a control unit (15) for controlling one or more LEDs (13; 23; 33) of said first subset (12; 24; 34) to switch between an emission mode, in which an LED emits electromagnetic radiation in the direction of the subject, and a detection mode, in which an LED generates a detection signal in dependence on the electromagnetic radiation incident on the LED, and a position determination unit (16) for determining the position of a subject with respect to the LED carrier based on the detection signals of one or more LEDs (13; 23; 33) of said first subset (12; 24; 34) in the detection mode, wherein the control unit (15) is configured to control one or more LEDs (13; 23, 25; 33, 35) to switch into the emission mode based on the determined position of the subject such that their emitted electromagnetic radiation provides phototherapy for the subject. A vital signs determination unit (17) is provided for determining one or more vital signs of the subject from one or more detection signals generated by one or more LEDs of said first subset.
