Summary:A driving arrangement for feeding a current generated by a high frequency generator (10) to a plurality of LED cells (50R, 50G, 50B) each including at least one respective LED, includes: - a magnetic element (35) in the flowpath of the current from the generator (10) to the LED cells (50R, 50G, 50B), - at least two electronic switches (30a, 30b) arranged for connection in a half bridge configuration to the output of the generator (10) and defining a common output node (31) to which the magnetic element (35) is connected, - a plurality of LED channels (1, 2, 3; 1', 2', 3') each for feeding a respective one of the LED cells (50R, 50G, 50B), wherein the LED channels (1, 2, 3; 1', 2', 3') are arranged in a parallel configuration therebetween starting from the magnetic element (35).
