Abstract
A driving arrangement for feeding a current generated by a high frequency generator (10) coupled with a magnetic element (11) to a plurality of LED cells (33) each including at least one LED. The arrangement includes a respective plurality of LED channels (1, 2, 3, 4; 1′, 2′, 3′, 4′) arranged in a parallel configuration and one or more coupled inductors (L12, L23, L34) the couple in pairs the channels of the plurality of LED channels (1, 2, 3, 4; 1′, 2′, 3′, 4′).
