Abstract

On décrit un élément 30 de protection contre l'éblouissement et la chaleur dans un projecteur de véhicule. L'élément de protection est situé à l'intérieur du projecteur à un endroit par rapport à la source lumineuse 22 tel qu'on évite la formation de son ombre dans le diagramme du faisceau lumineux projeté. Le rendement de la lampe électrique scellée hermétiquement qui forme la source lumineuse dans le projecteur de la présente invention peut en outre être amélioré par le dépôt sur l'enveloppe de la lampe d'un revêtement réfléchissant l'infrarouge. Application aux phares des véhicules automobiles.
