Abstract
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 reflects light emitted from the plurality of LEDs within the corresponding LED array. The optical system preferably further comprises a reflective aperture element positioned substantially adjacent to the output surface of each concentrator element. The aperture element includes a reflective surface and an aperture defined by the reflective surface. The reflective surface faces the output surface of each corresponding concentrator element to thereby ultimately provide substantially uniform light which is projected through the aperture.
