Scattered-photon extraction-based fixtures

Abstract

A light fixture includes a light source, a wavelength-conversion material, and a reflector. The light source is configured to emit a first radiation, and has a front surface and a back surface. The wavelength-conversion material is 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. The reflector is arranged over the back surface and configured to reflect the second portion away from the light source without passing through the wavelength-conversion material. The reflector has an end distant from the light source and is arranged in an elevation different from that of the wavelength-conversion material.
