Abstract
Un dispositif d'éclairage de véhicule (2) comprend une source de lumière de balayage (100) qui comprend une source de lumière à semi-conducteurs (110) et un moteur (120), et qui balaye une région à l'avant du dispositif d'éclairage, avec la lumière émise à partir de la source de lumière à semi-conducteurs (110), conformément au mouvement du moteur (120), et un circuit d'allumage (200) qui change la quantité de lumière de la source de lumière à semi-conducteurs (110) en synchronisation avec le mouvement du moteur (120), pendant une période d'allumage normal, de manière à obtenir un motif de distribution de lumière prédéterminé. Le circuit d'allumage (200) débute le mouvement du moteur (120), en réponse à une commande d'allumage pour un appel de phare pendant une période d'arrêt du moteur (120), et allume continûment la source de lumière à semi-conducteurs (110) de manière asynchrone avec le mouvement du moteur (120), pendant une période de démarrage qui précède la période d'allumage normal.
