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.

摘要： Various implementations disclosed herein include a distance measuring unit for signal transition time-based measurement of a distance to an object located in a detection field, with an emitter unit with multiple emitters, each designed to emit pulses in the form of electromagnetic radiation, a receiver unit for receiving the electromagnetic radiation after a distance-dependent transition time, and a tiltable mirror, wherein the distance measuring unit is configured such that a first of the emitters emits multiple pulses sequentially via the mirror, including at a first time in a first solid angle segment in a first angular position of the mirror, and at a second time in a second solid angle segment in a second angular position of the mirror; and a second of the emitters also emits a pulse in at least one of the solid angle segments via the mirror.

摘要： A method for operating a sensor system may include predefining a spatial region to be detected in the surroundings of a light emission device, scanning the predefined spatial region by light beams emitted by the light emission device in different spatial directions, driving an emitter with a control unit based on a random component, emitting light beams from the emitter in the direction of a scanning unit at random points in time, and deflecting the light beams, using the scanning unit, in the different spatial directions along which the light beams leave the light emission device. The sensor system may include the control unit and the light emission device where the light emission device includes the emitter and the scanning unit.
