Abstract

a) Phare de véhicule. b) Le réflecteur comporte quatre parties triangulaires, la partie supérieure 3 et la partie inférieure 4 sont disposées pour former une ligne focale horizontale F2 en avant de leur foyer commun. La partie de gauche 5 et la partie de droite 6, coupées par un plan horizontal, donnent une ligne elliptique et, coupées par un plan vertical donnent une ligne parabolique. La source lumineuse 8 est disposée au foyer commun des quatre parties. Une lentille convergente 7 est située en avant de la ligne focale horizontale, son foyer étant au voisinage de cette ligne. c) L'invention concerne un phare de véhicule et permet d'améliorer la configuration du faisceau obtenu tout en réduisant sensiblement la hauteur du phare.
