Abstract

La presente invención se refiere a una película reflectora de la luz, formada de un material transparente, caracterizada porque la película comprende una primera y una segunda superficies principales; la primera superficie es una superficie estructurada que forma una pluralidad de prismas triangulares que forman varios picos y ranuras y la segunda superficie es lisa; y un reflector de la luz adyacente a la segunda superficie de tal manera que la luz que entra a través de una primera superficie de uno de dichos picos será reflejada en forma interna por la segunda superficie de dicho pico hacia el reflector de luz y reflejada por el reflector de luz de manera que emerja de la película en un ángulo predeterminado hacia la dirección de la luz incidente.
