Abstract
A pulsed electric operating current that rises during a pulse duration is generated for operating at least one radiation-emitting semiconductor component. For this purpose, in a method for producing a control device for operating the at least one radiation-emitting semiconductor component, a temporal profile of a thermal impedance representative of the at least one radiation-emitting semiconductor component is determined. A profile of the electric operating current that is to be set is determined depending on the determined temporal profile of the thermal impedance. The control device is furthermore designed such that the profile of the operating current that is to be set is set in each case during the pulse duration.
