摘要： 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.

摘要： A lighting device includes at least one semiconductor light source, at least one incandescent filament configured to emit electromagnetic radiation when energized, and a carrier supporting both the semiconductor light source and the incandescent filament. A screen is defined by the carrier between the semiconductor light source and the incandescent filament, so as to shield the semiconductor light source from the electromagnetic radiation emitted by the incandescent filament. The incandescent filament connected in series with the at least one semiconductor light source.
