Abstract
Disclosed is a lighting device including a circuit including 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 including a capacitor and a coil. At least one of the diodes emits red light, blue light, and/or white light.

9. A circuit, comprising:
-
a first parallel branch including, at least a first antiparallel pair of light-emitting diodes, and a capacitor in series with the first antiparallel pair of light-emitting diodes; a second parallel branch including, at least a second antiparallel pair of light-emitting diodes, and a coil in series with the second antiparallel pair of light-emitting diodes, wherein the first branch is in parallel with the second branch, wherein a light culmination point of one of the first antiparallel pair of light-emitting diodes in the first parallel branch coincides with a point in time when a first one of the second antiparallel pair of light-emitting diodes in the second parallel branch switches on and when a second one of the second antiparallel pair of light-emitting diodes in the second parallel branch switches off. - View Dependent Claims (10, 11, 12)
