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. Elle concerne également un dispositif d'éclairage à base de LEDs mettant en œuvre un tel circuit et un procédé d'alimentation d'un ensemble de LEDs.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 control module (300) provided for: - short-circuiting at least one of said series diodes (106) when the supply signal decreases and - supplying, or re-energizing, at least one of said series diode (106) previously unpowered, or short-circuited, when the supply signal increases. It also relates to a lighting device based on LEDs implementing such a circuit and a method of supplying a set of LEDs.
