Abstract
Faro de cruce para vehículos automóviles, de tipo que comprende un reflector del tipo parabólico que define un eje óptico (A-A) y un foco (F), una fuente luminosa (L) situada sobre el eje óptico ligeramente por delante del foco, unos medios de corte (C) para interceptar una parte de los rayos salidos de la fuente y que van hacia el reflector, con el fin de definir, en el haz luminoso reflejado por el reflector, un límite de corte, caracterizado porque el reflector (R) está constituido por dos porciones de paraboloides del mismo foco que se extienden respectivamente a izquierda y a derecha del eje óptico, y porque la porción de paraboloide (RD) dispuesta, cuando el reflector esta visto de frente, por el lado correspondiente al sentido de circulación, tiene una focal superior a la de la otra porción de paraboloide (RG), de tal manera que la concentración del haz de cruce se encuentre mejorada por debajo del corte del lado del sentido de circulación.
