(FR) AGENCEMENT DE CIRCUIT RÉDUISANT AU MINIMUM UNE CHUTE DE TENSION INVERSE DANS TOUTE UNE DIODE ÉLECTROLUMINESCENTE
Abstract: front page image
(EN)The present invention relates to a LED driving circuit (1) comprising at least a first switching element (4) and at least a second switching element (5), each one of the first and second switching elements (4, 5) being in series electrical connection with at least a first and at least a second LED (2, 3) such that said at least first and at least second LEDs (2, 3) in association with each one of the first and second switching elements (4, 5) are independently drivable.
(FR)La présente invention concerne un circuit d'excitation (1) de DEL, comprenant au moins un premier élément de commutation (4) et au moins un second élément de commutation (5), chaque élément de commutation parmi les premier et second éléments de commutation (4, 5) étant en connexion électrique en série avec au moins une première et au moins une seconde DEL (2, 3), pour que lesdites au moins une première et au moins une seconde DEL (2, 3) en association avec chaque élément de commutation parmi les premier et second éléments de commutation (4, 5) puissent être excitées indépendamment.
