PROBLEM TO BE SOLVED: To improve lighting efficiency of a light fixture.SOLUTION: A scattered photon extraction light fixture includes an optic element having a first surface, a light source for emitting short wavelength radiation, disposed in opposition to the first surface of the optic element in a tangential direction or a perpendicular direction, a wavelength-conversion material disposed on the first surface of the optic element for receiving and down converting at least some of the short wavelength radiation emitted by the light source, and transferring a portion of the received and down converted radiation, and one or more reflectors positioned opposite the wavelength-conversion material. A scattered photon extraction light system includes a plurality of light emitting fixtures. One or more wavelength-conversion materials, in the embodiments of the present invention, are disposed remotely from the light source(s), and used to absorb radiation in one spectral region and emit radiation in another spectral region. Lighting efficiency is improved by capturing the short wavelength radiation and the down-converted radiation. |
