In one embodiment, the method is configured for producing optoelectronic semiconductor components () and includes the steps of:

Method for producing optoelectronic semiconductor components, leadframe assembly and optoelectronic semiconductor component

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.

Method for producing a control device for operating a radiation-emitting semiconductor component

Disclosed is a light-emitting diode chip comprising a semiconductor layer sequence suitable for emitting primary electromagnetic radiation and further comprising a converter layer that is applied to at least one main face of the semiconductor layer sequence and comprises at least one phosphor suitable for converting a portion of the primary radiation into secondary radiation, at least a portion of the secondary radiation and at least a portion of the unconverted primary radiation overlapping to form a mixed radiation with a resulting color space. The converter layer is purposefully structured to adjust a dependence of the resulting color space on viewing angle. Also disclosed is a method of making a light-emitting diode chip in which a converter layer is purposefully structured.
