Illumination System with Multiple Sets of Light Sources
First Claim
1. An illumination system (100, 200) comprising:
- a first sub-system (205) includinga first set of at least two differently colored light sources (L1-L3), said first set having a first spectral distribution;
a first light mixing device (103, 203) arranged in a direction of emission of light from said first set of light sources (L1-L3) and configured to mix light emitted by said first set of light sources (L1-L3);
a second sub-system (206) includinga second set of at least two differently colored light sources (L4-L6), said second set having a second spectral distribution; and
a second light mixing device (104, 204) arranged in a direction of emission of light from said second set of light sources (L4-L6) and configured to mix light emitted by said second set of light sources (L4-L6);
wherein said first and said second sub-systems are arranged to emit at least one common color, andwherein said light sources (L1-L6) are selected such that said first and said second spectral distribution complement each other, so that a color rendering index (CRI) of light emitted from said illumination system (100, 200) is greater that the CRI of light emitted from each of said sub-systems (205, 206).

Abstract
The present invention relates to an illumination system (200) including a first sub-system (205) comprising a first set (201) of at least two differently colored light sources where the first set (201) has a first spectral distribution, and a first light mixing device (203) arranged in a direction of emission of light from the first set of light sources and configured to mix light emitted by the first set of light sources. The illumination system further includes a second sub-system (206) comprising a second set (202) of at least two light sources where the second (202) set has a second spectral distribution, and a second light mixing device (204), also arranged in a direction of emission of light from the second set of light sources and configured to mix light emitted by the second set of light sources. The light sources are selected such that that the first and the second spectral distribution complement each other, so that a color rendering index (CRI) of light emitted from the illumination system (200) is greater that the CRI of light emitted from each of the sub-systems. Furthermore, the first (205) and the second (206) sub-systems are arranged to emit at least one common color, such as a shade of white.
