Abstract:
1. A lighting device, comprising: an electronic converter; and a circuit connected to an output of the electronic converter, the circuit comprising at least two parallel-connected light-emitting diodes of opposite pole in a first parallel branch and comprising at least two parallel-connected light-emitting diodes of opposite pole in a second parallel branch, and also comprising a capacitor and a coil, wherein the first parallel branch includes the capacitor and the second parallel branch includes the coil, wherein the light-emitting diodes of the first parallel branch emit white light having a first color temperature, wherein the light-emitting diodes of the second parallel branch emit white light having a second color temperature different from the first color temperature, and wherein an output frequency at the output of the converter is adjusted to adjust a ratio of an amount of the white light having the first color temperature and an amount of the white light having the second color temperature.
