Abstract
A driver circuit of lighting sources for powering a plurality of lighting sources, comprising switching means (20) which can be operated to modify the path of the overall power supply electric current crossing said lighting sources. Said switching means can be operated to switch the path of the overall power supply electric current between at least one first path, corresponding to a first circuit configuration of the interconnections between the lighting sources, and at least one second path, corresponding to a second circuit configuration of the interconnections between the lighting sources.
