Abstract

Official abstract text for this publication.

A scattered photon extraction light fixture includes an optic element having a first surface; a light source for emitting short wavelength radiation, the light source disposed opposite, perpendicular, or tangential to the first surface of the optic element; 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 and down-converted radiation.

First claim

Opening claim text (preview).

What is claimed: 1. A light fixture comprising: a light source configured to emit a first radiation, and having a front surface and a back surface; a wavelength-conversion material arranged under the front surface and configured to convert the first radiation to a second radiation which has a first portion not able to reach the reflector and a second portion able to reach the reflector; and a reflector arranged over the back surface and configured to reflect the second portion…
