Illumination unit, projecting engine and method for generating illumination light
First Claim
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.

Abstract
It is proposed to provide in an illumination unit (10) a light combining section (15) being adapted for receiving and combining first and second primary illumination light (L11, L12) or a derivative thereof and a light collecting, integrating and redirecting section (20) being adapted for receiving, collecting, integrating and redirecting first and second primary illumination light (L11, L12) or a derivative thereof, wherein said light combining section (15) and said light collecting, integrating and redirecting section (20) are at least partly arranged in a spatially mingled manner with respect to each other. Thereby from said first and second primary illumination light (L11, L12) collected, integrated and redirected combined primary illumination light (CL1) can be obtained and emitted as secondary illumination light (L2) having controlled spectral properties and an essentially uniformized spatial intensity distribution.

17. A method for generating and providing illumination light in a projection engine, comprising:
-
generating first and second primary illumination light having at least in part essentially complementary spectra;
with respect to each other;combining said first and second primary illumination lights or parts or derivates thereof; and collecting, integrating, and redirecting said first and second primary illumination lights or parts or derivates thereof, wherein the processes of combining said first and second primary illumination lights or parts or derivates thereof and of collecting, integrating, and redirecting said first and second primary illumination lights or parts or derivates thereof are performed in a spatially and/or temporally mingled, mixed up, integrated, and/or overlapping manner with respect to each other, thereby obtaining and outputting collected, integrated, and redirected combined primary illumination light as secondary illumination light having controlled spectral properties and an essentially uniformized intensity distribution.
