Abstract (en)

[origin: CN110139421A] The invention relates to a circuit arrangement (1) for alternately switching on and off at least two light strands for a vehicle headlight electrically connected in parallel, comprising: a parallel circuit having at least two electrically parallel light strands, wherein each light strand is composed of a plurality of light sources (7) electrically connected in series with each other; at least oneenergy source (5) for supplying power to the parallel circuit (4), wherein the parallel circuit (4) is connected to the energy source (5) and/or the energy source (5) is designed such that, in the onstate of a switching element (6), the voltage applied to the parallel circuit (4) is within the operating range of the first light strand (2) and thus the first light strand (2) is turned on and the second light strand (3) is turned off, and the voltage applied to the parallel circuit (4) is raised in the working range of the second light strand (3) when the switching element (6) is not conductingand thus the first light strand (2) is turned off and the second lamp branch (3) is switched on.
