Abstract
In order to further develop a circuit arrangement and a method for controlling at least one light emitting component, to which a threshold current is applied, with the circuit arrangement being supplied with voltage by means of at least one supply element, and with the light emitting component being controlled by means of at least one switching element arranged between at least one current limiting element and the light emitting component using at least one switching controller, in such a way that the power efficiency is significantly increased in comparison to prior art, it is proposed that a maximum value of the current is provided by means of the current limiting element, and that the logical '1' of the data to be transmitted by means of the light emitting component is represented by periodic switching between the zero value of the current and the maximum value of the current supplied to the light emitting component.
