摘要： According to various illustrative embodiments of the present invention, a device for a light projection system includes a single light emitting diode array comprising at least one green die, at least one blue die, and at least one red die, a single light collection, integration, and etendue-matching optic element comprising a tapered light pipe capable of collecting substantially all light emitted by the single light emitting diode array and spatially integrating the substantially all the light emitted by the single light emitting diode array, and a telecentric relay using at least one of spherical and aspherical refractive and reflective components. The device also includes an illumination wedge prism, a digital micromirror device capable of modulating the substantially all the light emitted by the single light emitting diode array, and a projection total internal reflection prism, the projection total internal reflection prism disposed between the illumination wedge prism and the digital micromirror device. The device also includes a projection lens, wherein the telecentric relay provides the substantially all the light emitted by the single light emitting diode array through the illumination wedge prism and through the projection total internal reflection prism to the digital micromirror device that reflects the substantially all the light emitted by the single light emitting diode array back through the projection total internal reflection prism that totally internally reflects the substantially all the light emitted by the single light emitting diode array through the projection lens.
