<p>A current regulation unit in a circuit composed of light sources, connected in series, interposed between an electric source (SE) and the series connection electric circuit (E) of the light sources (SI<SUB>1</SUB>, SI<SUB>2</SUB>,..., SI<SUB>J</SUB>, SI<SUB>N</SUB>),..., includes: at least one conversion apparatus (AC<SUB>1 </SUB>AC<SUB>2</SUB>) for generating an alternating voltage, having pre-settable characteristics; a transformer (T), connected in cascade to the conversion apparatus (AC<SUB>1</SUB>, AC<SUB>2</SUB>) and connected to the electric circuit (E); and an electric control unit (CE), connected to the conversion apparatus (AC<SUB>1</SUB>, AC<SUB>2</SUB>) for controlling the modulation of the alternating voltage supplied by the conversion apparatus, in order to obtain a current (z) circulating in the electric circuit (E) having pre-settable electric characteristics. The conversion apparatus (AC<SUB>1</SUB>, AC<SUB>2</SUB>) is mounted on a printed board (SC<SUB>1</SUB>, SC<SUB>2</SUB>), removable from a corresponding slot (SL<SUB>1</SUB>, SL<SUB>2</SUB>), made in the regulation unit (UR).</p> |
