Abstract
A method for controlling at least two light-emitting diodes connected in series of a circuit assembly of a lighting device may include supplying the light-emitting diodes with a specifiable current by means of a controllable current source unit. The method may include connecting a bypass element in parallel with at least one of the light emitting diodes. The method may include detecting an electric supply voltage to the series circuit of the light-emitting diodes and the current source circuit, and controlling an electric conductivity of the bypass element based on the detected electric supply voltage and/or the light-emitting diode current.
