Abstract

　La présente invention concerne un dispositif d'éclairage à DEL 10, pourvu d'une unité d'éclairage à DEL 11, ayant une diode électroluminescente, DEL, 13 montée sur un substrat 12, et un circuit de commande d'excitation 20 servant à fournir un courant d'excitation à l'unité d'éclairage à DEL 11. Le circuit de commande d'excitation 20, au début de la fourniture de courant à l'unité d'éclairage à DEL 11, augmente de manière incrémentielle la quantité de courant fournie I à une valeur de courant d'excitation prescrite 10 établie à l'avance.
