Fluorescent volume light source with active chromphore

An illumination system, such as might be used for illuminating a projection system, includes at least a first source of incoherent light capable of generating light in a first wavelength range. The system includes at least one active chromophore layer, sandwiched by transparent materials into a mult...

Beschreibung
Zusammenfassung:	An illumination system, such as might be used for illuminating a projection system, includes at least a first source of incoherent light capable of generating light in a first wavelength range. The system includes at least one active chromophore layer, sandwiched by transparent materials into a multi-layer body. They active chromophore layer emits light in a second wavelength range, different from the first wavelength range, when illuminated by light in the first wavelength range. The multi-layer body has an extraction area and at least some of the light at the second wavelength is internally reflected within the body to the extraction area.
