Abstract

La présente invention concerne un dispositif d'éclairage. Le dispositif d'éclairage comprend un circuit d'excitation associé, qui fournit un signal d'excitation de commutation d'un convertisseur, le circuit d'excitation comprenant : une unité de génération d'instant terminal pour générer une impulsion de commande qui exprime un instant terminal d'un temps de marche minimum selon un changement de fréquence d'un signal d'oscillation utilisé pour générer le signal d'excitation, au sein d'un intervalle de mise en marche du convertisseur; et une unité de détermination de temps de marche minimum, pour fournir, au sein d'un intervalle de mise en marche du convertisseur, une impulsion de temps de marche minimum qui définit le temps de marche minimum qui comprend une période d'un instant de commencement de mise en marche du convertisseur à l'instant terminal, en utilisant l'impulsion de commande.
