Abstract[English]
Techniques for life extension of light source controller circuitry are described. A thermal rollover algorithm is presented to protect a light source controller mounted on an electronics board from overtemperature caused by the light source. The method includes adjusting dimming of LED modules based on temperature of an electronics board on which control circuitry is mounted.[French]
L'invention concerne des techniques d'extension de durée de vie d'un ensemble de circuits de commande de source de lumière. L'invention concerne également un algorithme de retournement thermique permettant de protéger un dispositif de commande de source de lumière monté sur une carte électronique contre une surchauffe provoquée par la source de lumière. Le procédé consiste à ajuster la gradation de modules DEL sur la base de la température d'une carte électronique sur laquelle est monté un ensemble de circuits de commande.
