Abstract:
1. A color adjusting arrangement comprising: a first wavelength converting material arranged to receive ambient light incident from a viewing position outside the color adjusting arrangement, and capable of converting ambient light of a first wavelength range into light of a second wavelength range, and/or reflecting ambient light of the second wavelength range, the second wavelength range being part of the visible light spectrum; and a complementary wavelength converting material arranged to receive ambient light and capable of converting part of the ambient light into light of a complementary wavelength range, which is complementary to the second wavelength range, and arranged to allow mixing of light of the second wavelength range and the complementary wavelength range, and a dichroic reflector, wherein: the light of the second wavelength range that is emitted and/or reflected by the first wavelength converting material is mixed with light of the complementary wavelength range when leaving the color adjusting arrangement towards the viewing position, the light leaving the color adjusting arrangement having a color point substantially near the black body line, and the dichroic reflector reflects part of the ambient light that is not converted into the light of the complementary range back into the complementary wavelength converting material, and transmits the light of the second wavelength range toward the viewing position.
