A driver arrangement comprises a current regulator (12), to which at least one light-emitting diode (15, 42) can be connected, and a driver circuit (13) that is coupled to the current regulator (12) and features a measurement input (20) for receiving a measurement signal (SM) that is dependent on the operation of the at least one light-emitting diode (15, 42). The driver circuit (13) is designed for adjusting the current level of the current regulator current (IS) of the current regulator (12) in dependence on the measurement signal (SM) such that a light quantity (SL) emitted by the at least one light emitting diode (15, 42) has a constant brightness value.
