A circuit arrangement for driving semiconductor light sources is provided. The circuit arrangement may include video electronics, which are configured to generate a timing signal and an image value table; a driver circuit, which comprises a digital and an analogue part, and a semiconductor light source module, which can contain one or a plurality of semiconductor light sources; and a switch being arranged between the driver circuit and the semiconductor light source module, which switch is driven by the driver circuit and can switch the desired value for the power supply for the semiconductor light source module away from an analogue/digital converter to logic 0.
