Abstract
A color mixing light emitting diode (LED) assembly comprises a carrier and at least three LEDs that are arranged on the carrier and configured to emit light in mutually different colors and together generate an output radiation that corresponds to an additive color mix, wherein each of the LEDs has an individual emission characteristic. The LED assembly furthermore comprises a respective driver input for each of the LEDs to supply the LEDs with electrical energy, wherein the emission characteristics of the LEDs are dependent on the respective energy supply so that the color mix of the output radiation can be set by varying the respective energy supply at the driver inputs. The LED assembly has a calibration information element that includes at least one readable calibration value for each of the LEDs that represents the individual emission characteristic of the respective LED.
