Abstract

According to the present disclosure, a lighting device provides: an elongate support element, a plurality of lighting units distributed along the length of said support element, each of said units including: a set of electrically powered light radiation sources, a driver supplying said set of light radiation sources with a supply current having an intensity which is a function of an impedance value sensed at a current control input of driver. At least one of said lighting units includes a mounting seat for a lighting adjustment impedance, said seat having an electrical connection to the current control input of at least one driver, so that the intensity of the current supplied by driver to a respective set of light radiation sources is a function of the impedance value of a lighting adjustment impedance arranged at said seat.
