Beschreibung
Zusammenfassung:	The invention relates to a circuit arrangement for operating a semiconductor light source, comprisinginput terminals for connecting a supply voltage,input filter means,a converter provided with a switching element having a control circuit, and provided with inductive means, andoutput terminals for connecting the semiconductor light source.The switching element is periodically driven into conduction for a period ton. According to the invention, the converter is formed by a flyback converter, and the inductive means are formed by a transformer, and the control circuit controls the ton.
