摘要： An optical system for a digital light projection system is provided. The optical system comprises a plurality of LED arrays, wherein each LED array comprises a plurality of LEDs. The optical system also comprises an optical concentrator element positioned substantially adjacent to each of the LED arrays, wherein each concentrator element totally internally reflects light emitted from the plurality of LEDs within the corresponding LED array so as to provide substantially uniform light at an output surface of each concentrator element, and wherein the concentrator element has a complex conic shape. The optical system preferably further comprises an optical combiner element, wherein the output surface of each concentrator element is positioned substantially adjacent to a corresponding side of the combiner element, and wherein the combiner element spatially combines the substantially uniform light provided at the output surface of each concentrator element so as to form substantially white light at an output surface of the combiner element.
