Abstract

The invention relates to a lighting device having at least one light-emitting diode module (1), which comprises at least two light-emitting diodes (11), which during operation emit light having colors that differ from each other, at least one driver (2), which is designed to supply the light-emitting diodes (11) of exactly one of the at least one light-emitting diode modules (1) with operating current, exactly one control device (3), which during operation controls the at least one light-emitting diode module (1) in an open-loop and/or closed-loop manner, wherein each light-emitting diode module (1) is biuniquely associated with a driver (2), and the control device (3) controls each light-emitting diode module (1) in an open-loop and/or closed-loop manner by means of the driver associated with the light-emitting diode module (1).
