Abstract:
1. A circuit for controlling at least one light-emitting component, comprising: a) at least one first supply element provided for supplying the circuit with voltage; b) at least one switching element provided for controlling the light-emitting component by switching the switching element at least between a first switching position and a second switching position; c) at least one further circuit component being provided, and being switched to active or switched on in the second switching position; d) the further circuit component is at least one voltage-limiting element for varying the operating voltage of the light-emitting component; e) the voltage-limiting element is disposed in parallel with the switching element in the first switching position; and f) the voltage-limiting element includes at least one second supply element, supported by a decoupling capacitor on the output side, and at least one transistor, or at least one p-channel transistor, or at least one p-channel field-effect transistor (FET).
