Abstract

La presente invención se refiere a una fuente de luz en línea, dependiente de la dirección, caracterizada porque comprende: (a) un conductor de luz que tiene un lado interior y dos extremos opuestos, siendo más largo en la longitud que en el ancho de la sección transversal, que consiste esencialmente de una película delgada hueca de un material de reflexión totalmente interna, y (b) dos fuentes de luz las cuales producen iluminaciones que difieren en por lo menos una propiedad óptica, una primera fuente dirigida a un extremo del conducto de luz y una segunda fuente dirigida al extremo opuesto del conducto de luz, en la cual la iluminación que deja los lados del conducto de luz tiene una propiedad óptica determinada por la dirección en la cual viaja a través del conducto de luz, y la cual deja el conducto de luz a esencialmente el mismo ángulo en el cual choca con el lado interior del conducto de luz.
