Title (EN) FLUX COMPENSATION LED DRIVER SYSTEM AND METHOD
(FR) SYSTEME ET PROCEDE DE COMMANDE DE DEL. A COMPENSATION DE FLUX
Abstract: front page image
(EN)A flux compensation led driver system and method including a driver for a light emitting diode (LED) string having an associated flux bin index including a power converter (22) responsive to a gain signal (34) and generating flux indexed drive current (36); an LED connector (24) operably connected to the power converter (22) and operable to receive the LED string (26); and a gain block (32) comparing a sensed drive current signal (38) and a drive current setpoint (28) to generate the gain signal (34). The gain block (32) is responsive to a flux index selector (30) to adjust the gain signal (34) for the associated flux bin index.
(FR)L'invention concerne un système et un procédé de commande de DEL à compensation de flux, comprenant un mécanisme de commande pour chaîne de diodes électroluminescentes (DEL) comportant un index binaire de flux associé intégrant un convertisseur de puissance (22) sensible à un signal de gain (34) et produisant un courant de commande à flux indexé (36); un connecteur de DEL (24) relié en fonctionnement au convertisseur de puissance (22) et exploitable pour recevoir la chaîne de DEL (26); et un bloc de gain (23) comparant un signal de courant de commande détecté (38) et une valeur prédéterminée de courant de commande (28) pour produire un signal de gain (34). Le bloc de gain (32) est sensible à un sélecteur d'index de flux (30) pour ajuster le signal de gain (34) pour l'index binaire de flux associé.
