Abstract

La invencion se refiere a un sistema de iluminacion que hace posible la combinacion de dos haces de luz (12.1, 12.2). el sistema comprende un prisma (20) definido por dos superficies de entrada (20.1, 20.2) que forman un diedro. Un dispositivo integrador (30) es acoplado a una superficie de salida (20.3) del prisma. El prisma es penetrado por cada haz via una de las superficies de entrada. El haz es reflejado hacia la superficie de salida (20.3) por reflexion interna sobre la otra superficie de entrada. Los haces son esencialmente enfocados sobre la superficie de entrada del dispositivo integrador de tal suerte que es proporcionado un haz (40) de salida, practicamente homogeneo. La invencion puede ser utilizada para dispositivos de proyeccion y retroproyeccion.
