Circuit optoelectronics LED has reduced flickering
2014
The invention relates to an optoelectronic circuit (30) for receiving a variable voltage containing an alternating increasing and decreasing phases. The optoelectronic circuit comprises an alternation of resistive elements (R) and sets (Di) of light emitting diodes connected in series, each set comprising two terminals, each resistive element being interposed between two successive sets. The optoelectronic circuit comprises, for each set of a plurality of said sets, a transistor (Ti) metal oxide gate field effect depletion whose drain and source are coupled to the terminals of said set and whose gate is coupled to the one of the terminals of the next set.
