Abstract
The invention relates to a system for recording characteristic curves for a light-emitting diode arrangement () comprising at least one light-emitting diode (). A control unit () is used to operate the light-emitting diode arrangement () and to record the diode current () and the voltage () on the light-emitting diode arrangement (). The control unit () is also used to record a first current/voltage pair (P) and a different second current/voltage pair (P), at a first temperature of the light-emitting diode arrangement (), and a third current/voltage pair (P) and a different fourth current/voltage pair (P), at a second temperature of the light-emitting diode arrangement (). The invention also relates to a method for recording characteristic curves of a light-emitting diode arrangement.
