Abstract

Un reflector para lámparas de vehículos, que está confeccionado a base de material transparente y presenta en el vértice del dorso prismas de reflexión total, que reflejan la luz penetrante en el cuerpo reflector, caracterizado porque los prismas de reflexión total están conformados a manera de prismas de techo de 90º, cuya cumbrera está dirigida en sentido radial hacia el eje óptico, y porque el ángulo comprendido entre la cumbrera y el eje óptico está determinado en cada punto de la cumbrera por la perpendicular con especto a la bisectriz del ángulo formado por el rayo incidente y el rayo reflejado discurrentes en el material del reflector.
