Abstract

L'invention concerne un circuit électronique de commande d'au moins une première source de lumière (D11) et une seconde source de lumière (D21), comprenant un générateur (GEN) d'un signal porteur d'impulsions (PWM1) de rapport cyclique variable, caractérisé par des moyens conçus pour allumer la première source de lumière (D11) conformément au signal porteur d'impulsions (PWM1) pendant un premier intervalle de temps et pour allumer la seconde source de lumière (D21) conformément au signal porteur d'impulsions (PWM1) pendant un second intervalle de temps (T2).
