Abstract

Aparato de presentación por proyección que proyecta una imagen proporcionando como entrada un haz luminoso emitido por una fuente luminosa a un dispositivo de modulación de luz espacial, se pretende proporcionar un conjunto de lentes como un componente de un sistema óptico de iluminación que sea de bajo coste de fabricación, proporcione alta iluminancia de pantalla y permita la miniaturización del aparato de presentación del tipo de proyección. La dimensión de las lentes celulares de un segundo conjunto de lentes es no uniforme en una de las direcciones de filas y de columnas. Como las lentes celulares son rectangulares, vistas por el lado frontal, el segundo conjunto de lentes se puede fabricar con un molde metálico que tiene una forma sencilla. Las líneas de delimitación entre las lentes celulares son rectas y las diferencias de nivel en las líneas de delimitación son pequeñas, las marcas hundidas del segundo conjunto de lentes son pequeñas, y el rendimiento de utilización de los haces luminosos es alto. Además, como la dimensión de las lentes celulares es no uniforme en la otra de las direcciones de filas y de columnas, se puede reducir la dimensión correspondiente del segundo conjunto de lentes.
