Abstract:
(EN) An LED drive circuit drives an LED module. The LED module has a light-emitting diode, and an identification unit having characteristic information relating to light-emitting characteristics of the light-emitting diode. The LED drive circuit includes a detection unit and a drive circuit. The detection unit is provided for detecting characteristic information, and generates a detection signal that corresponds to the characteristic information. The drive circuit generates drive current by a drive signal supplied according to the characteristic information based on the detection signal, and supplies the drive current to drive the light-emitting diode.
(FR) La présente invention concerne un circuit d’excitation de LED qui excite un module de LED. Le module de LED comporte une diode électroluminescente, et une unité d’identification comportant des informations caractéristiques relatives à des caractéristiques d’émission de lumière de la diode électroluminescente. Le circuit d’excitation de LED comprend une unité de détection et un circuit d’excitation. L’unité de détection est fournie pour détecter des informations caractéristiques, et génère un signal de détection qui correspond aux informations caractéristiques. Le circuit d’excitation génère un courant d’excitation au moyen d’un signal d’excitation fourni en fonction des informations caractéristiques sur la base du signal de détection, et fournit le courant d’excitation pour exciter la diode électroluminescente.
