A supply system for light sources connected in series is powered by one power line (SE), and a plurality of adjustment units (UR1, UR2, . . . , URJ, . . . URN) are interposed between the power line (SE) and an electric circuit (E) for in-series connection of light sources (SI1, SI2, . . . , SIJ, . . . SIN). Each of the adjustment units (URJ) has a (DC/ACJ) generator device for the generation of an alternating voltage. An electric transformer (TJ) is connected in cascade and functionally with the electric circuit (E). An electric central unit (C), connected to the generator devices, controls modulation of the alternating voltage supplied by the generator device, so as to obtain a current (z) circulating in the electric circuit (E), having pre-defined electric characteristics.
