<p>A LED arrangement includes: - a plurality of cells (0, 1, 2, 3) each including at least one respective LED having a binning class as a function of its emission wavelength (L<SUB>1</SUB>, L<SUB>2</SUB>) and brightness (B<SUB>1</SUB>, B<SUB>2</SUB>) characteristics, - a plurality of impedance elements (R0, R1, R2, R3) respectively coupled with the cells (0, 1, 2, 3), each impedance element (R0, R1, R2, R3) having an impedance value indicative of the binning class of the at least one LED included in the respective cell (0, 1, 2, 3), and - a controller (5) configured for sensing (6, 80, 81, 82, 83) the impedance values of the impedance elements (R0, R1, R2, R3) and adaptively drive each cell (0, 1, 2, 3) as a function of its binning class as indicated by the impedance element (R0, R1, R2, R3) coupled to the cell.</p> |
