Abstract

L'invention concerne un circuit pour alimenter un ensemble (102) de diodes avec un signal électrique à courant continu et constant, dit d'alimentation, ledit ensemble de diodes (102) comprenant un groupe (106) d'une pluralité de diodes (106), dites séries, montées en série, ledit circuit étant caractérisé en ce qu'il comprend un module (300) de régulation prévu pour :
- court-circuiter au moins une desdites diodes série (106) lorsque le signal d'alimentation diminue, et
- alimenter, ou réalimenter, au moins une desdites diode série (106) préalablement non alimentée, ou court-circuitée, lorsque le signal d'alimentation augmente.A circuit for powering an array (102) of diodes with a DC and constant power supply signal, said power supply, said diode array (102) comprising a group (106) of a plurality of diodes ( 106), said series, connected in series, said circuit being characterized in that it comprises a regulation module (300) provided for:
- shorting at least one of said series diodes (106) when the feed signal decreases, and
- Supply, or supply, at least one of said series diode (106) previously unpowered, or short-circuited, when the supply signal increases.

Elle concerne également un dispositif d'éclairage à base de LEDs mettant en oeuvre un tel circuit et un procédé d'alimentation d'un ensemble de LEDs.
