Patent ID: 8525435

Claim:
A circuit arrangement for controlling at least one light emitting component, to which a threshold current is applied, wherein the circuit arrangement comprises: at least one supply element for supplying the circuit arrangement with voltage, at least one current limiting element being arranged between the supply element and the light emitting component, and at least one switching element for controlling the light emitting component by means of at least one switching controller, with the switching element being arranged between the current limiting element and the light emitting component, wherein a maximum value of the current is providable by means of the current limiting element, and wherein a logical “1” of data to be transmitted by means of the light emitting component is given as periodic switching between a zero value of the current and the maximum value of the current supplied to the light emitting component, and wherein the current limiting element is capacitively supported, and wherein in case of capacitive decoupling of the current limiting element, the maximum value of the current is given essentially by the average current.
