Abstract

The invention relates to a circuit for dimming a lamp comprising at least two illumination units. The circuit comprises a control unit for coupling a brightness with a color temperature depending on an input signal, the at least two illumination units being controllable by the control unit depending on the input signal. The invention also relates to a method for dimming a lamp.
