Ac Driven Light-Emitting Diodes

摘要

The invention relates to a circuit ( 2 ) comprising at least two parallel-connected light-emitting diodes ( 4, 5 ) opposite poled in a first parallel branch ( 12 ) and comprising at least two parallel-connected light-emitting diodes ( 6, 7 ) opposite poled in a second parallel branch ( 13 ), and also comprising a capacitor ( 8 ) and a coil ( 9 ). According to the invention, the first parallel branch ( 12 ) has a capacitor ( 8 ) and the second parallel branch ( 13 ) has the coil ( 9 ). On account of the capacitive parallel branch ( 10 ) and the inductive parallel branch ( 11 ), idle currents arise which are phase-shifted with respect to one another. The idle currents compensate one another and light changes of the oppositely-poled diode pairs take place at different points in time. A light current is thun smoothed.
