ABSTRACT:
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 also includes a body containing a fluorescent material that emits light in a second wavelength range, different from the first wavelength range, when illuminated by light in the first wavelength range. The 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.
