Abstract
An illumination delivery system for generating sustained secondary emission that includes at least an illumination source, a waveguide, and one or more energy conversion layers is disclosed. Also disclosed are methods of using the inventive illumination delivery system for generating sustained secondary emission.
Claims40
An illumination delivery system for generating sustained secondary emission, said illumination delivery system comprising:
- an illumination source that emits a primary electromagnetic radiation,
- a waveguide that receives and propagates said primary electromagnetic radiation, and one or more energy conversion layers that convert at least a portion of said primary electromagnetic radiation to a longer output wavelength, said one or more energy conversion layers comprising a polymer and one or more fluorescent materials having an absorption spectrum that at least partially overlaps with said primary electromagnetic radiation,
- wherein said waveguide transmits at least a portion of said primary electromagnetic radiation to said one or more energy conversion layers.
A method for generating sustained secondary emission, said method comprising:
- providing an illumination delivery system for generating sustained secondary emission, said illumination delivery system comprising:
- (i) an illumination source that emits a primary electromagnetic radiation,
- (ii) a waveguide that receives and propagates said primary electromagnetic radiation, and
- (iii) one or more energy conversion layers comprising a polymer and one or more fluorescent materials having an absorption spectrum that at least partially overlaps with said primary electromagnetic radiation,
- wherein said waveguide transmits at least a portion of said primary electromagnetic radiation to said one or more energy conversion layers, such that said one or more energy conversion layers subsequently convert at least a portion of said primary electromagnetic radiation to a longer output wavelength.
