Circuit-Arrangement for Modulating an Led and Method for Operating Same

摘要

To achieve high modulation frequencies when modulating an LED, a circuit-arrangement for modulating at least one LED comprises a modulation-circuit ( 3 ) parallel to the LED, wherein the modulation-circuit ( 3 ) comprises in a series connection a switching device and a threshold device. In a method for operating an LED, the LED is modulated by alternating the switching device between a closed state and an open state.
