Abstract

Une lampe de véhicule (1) comporte un élément laser à semiconducteur (9) configuré pour émettre de la lumière laser ; une lentille de condenseur (11) configurée pour condenser la lumière laser ; un luminophore (13) configuré pour former de la lumière blanche en convertissant la longueur d'onde d'au moins une partie de la lumière laser condensée, et un réflecteur (7) configuré pour réfléchir la lumière blanche. Une partie de formation de lumière dispersée (23) est formée sur une surface du réflecteur (7), qui est une surface sur laquelle un trajet obtenu en prolongeant le trajet optique de la lumière laser avant que la lumière laser frappe le luminophore (13) coupe le réflecteur (7).
