Zusammenfassung:	The disclosure relates to a lighting device (1) that includes (i) a multi-LED chip (2), wherein the multi-LED chip (2) has a plurality of LED light sources (2′) as well as a plurality of regulating elements (2″), wherein each LED light source (2′) is assigned a regulating element (2″) connected in series for regulating the current consumption of the respective LED light source (2′) and together with the regulating element (2″) forms a controllable string (2a, 2b, 2c), wherein each LED light source (2′) is designed to be individually switchable; and (ii) an electrical control unit (3), which has a step-down converter (3a) with a voltage input (3aVin), a feedback input (3aFB) and a voltage output (3aVout) and a microcontroller (3b) with a signal input (3bSin) and a signal output (3bSout).
