Abstract (en)

[origin: WO2007141254A1] The invention relates to a circuit unit for a semiconductor unit which produces radiation, with a forward voltage U<SUB>f</SUB> being applied during operation to the semiconductor unit which produces radiation, and with a forward current I<SUB>f</SUB> flowing through the semiconductor unit which produces radiation, with the circuit unit regulating the forward current I<SUB>f</SUB> such that an actual value V<SUB>act</SUB> which depends on the forward current I<SUB>f</SUB> and the forward voltage U<SUB>f</SUB> assumes a predetermined nominal value V<SUB>nom</SUB>. The invention also relates to a radiation source.
