Abstract

Una unidad de iluminación proporciona luz para un sistema de despliegue de proyección. La unidad de iluminación incluye una guía de luz definida por un ángulo de entrada. Una fuente 200 de luz proporciona la luz emitida de conformidad con un patrón de radiación característico. Un arreglo de lente incluye por lo menos un lente que recolecta una porción de la luz emitida a través del patrón de radaición y enfoca la luz recolectada para así alcanzar la guía de luz dentro de un ángulo 215 de entrada. La porción de la luz emitida que se recolecta y la luz recolectada que entra en la guía de luz dentro del ángulo, coopera para optimizar el porcentaje de la luz emitida por la fuente de luz que se puede utilizar por la porción de ópticos de proyección del sistema.
