1. A method for adjusting the brightness of at least one LED according to a changing supply voltage provided to the at least one LED, wherein the supply voltage is provided by means of an electrical supply apparatus, which is designed to provide supply voltages over a predefined voltage range to adjust the brightness of an incandescent lamp, wherein the method is carried out by means of a control unit, which is provided for electrically coupling the electrical supply apparatus (100) to the at least one LED, comprising the following steps:

  • acquiring a parameter which indicates the changing supply voltage; and

    providing, on the basis of the acquired parameter, a control voltage of the at least one LED for adjusting an LED current such that the at least one LED has a predefined relative brightness change over the predefined voltage range.
