Abstract

Procédé de gestion de la puissance d'un module optique de projecteur (1) à diode électroluminescente pour véhicule automobile comprenant : l'application d'un courant nominal (5) au module optique ; et la diminution (6) du courant appliqué au module optique lorsque la température dans le module optique est supérieure ou égale à un premier seuil (T1). En outre, on augmente (7) le courant appliqué au module optique lorsque la température dans le module optique est inférieure ou égale à un deuxième seuil (T2), la température du deuxième seuil (T2) étant inférieure à la température du premier seuil (T1).Method for managing the power of a headlamp optical module (1) with a light-emitting diode for a motor vehicle, comprising: applying a nominal current (5) to the optical module; and decreasing (6) the current applied to the optical module when the temperature in the optical module is greater than or equal to a first threshold (T1). In addition, the current applied to the optical module is increased (7) when the temperature in the optical module is less than or equal to a second threshold (T2), the temperature of the second threshold (T2) being lower than the temperature of the first threshold ( T1).
