Abstract:
1. An illumination for a projection engine comprising: at least a first light source device and a second light source device being adapted for generating and for emitting first and second primary illumination light, respectively, said first and second primary illumination light having at least in part essentially complementary spectra with respect to each other: a light combining area, section, portion, or device being adapted for receiving and combining or superposing said first and second primary illumination light or parts or derivates thereof; and a light collecting, intergrating redirecting area, section, portion, or unit being adapted for receiving, collecting, integrating, and redirecting said first and second primary illumination light or parts or derivates thereof, wherein said light combining area, section, portion, or device and said light collecting, integrating, and redirecting area, section, portion, or unit or parts thereof are formed and/or arranged in a spatially mingled, mixed up, integrated, and/or overlapping manner with respect to each other, thereby being adapted for cooperating and for obtaining from said first and second primary illumination light and for emitting collected, integrated, and redirected combined primary illumination light as secondary illumination light having controlled spectral properties and an essentially uniformized spatial intensity distribution.
