Patent attributes
In order to further develop a circuit arrangement or circuit, in particular driver circuit, and a method for controlling at least one light-emitting component, in particular at least one electro-optical transducer, for example at least one light-emitting diode (LED) or electroluminescent diode or at least one laser, such as at least one semiconductor laser, by switching at least one switching element at least between a first switching position and a second switching position, at least one further circuit component is switched to active or switched on in the second switching position, so that current drain and output resistance are as low as possible, so that the highest possible frequency or switching speed as well as the highest possible output voltage for the light-emitting component can be achieved, it is proposed that the light-emitting component is controlled by varying its operating voltage.
