    • 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.
    • 提供了一种用于数字光投射系统的光学系统。 该光学系统包括多个LED阵列,其中每个LED阵列包括多个LED。 光学系统还包括基本上邻近于每个LED阵列定位的聚光器元件,其中每个聚光器元件反射从相应的LED阵列内的多个LED发射的光。 光学系统优选地还包括反射孔径元件,其基本上邻近每个聚光器元件的输出表面定位。 孔元件包括反射表面和由反射表面限定的孔。 反射表面面对每个对应的聚光元件的输出表面,从而最终提供通过该孔突出的基本均匀的光。
