Light source
First Claim
1. An integrated light source comprising:
- an emissive radiation source emitting a first spectrum of radiation;
an optical element located to direct the first spectrum of radiation from said emissive radiation source;
a volumetric spectrum converter being located to convert the first spectrum of radiation directed from said emissive radiation source to a second spectrum of radiation different from said first spectrum of radiation, the volumetric spectrum converter including a plurality of layers forming a homogeneous composite substrate with a plurality of suspended particles volumetrically disposed within each of the plurality of layers of the homogeneous composite substrate, each of the plurality of suspended particles being configured to convert the first spectrum of radiation to the second spectrum of radiation;
an optical reflector located about said volumetric spectrum converter;
an output filter, said reflector being located to reflect said volumetric spectrum converter emissions towards said output filter; and
a package body having an internal cavity, said cavity containing said emissive radiation source, optical element, volumetric spectrum converter, reflector, and output filter,wherein desired light radiates from said cavity through said output filter.

Abstract
An integrated light source includes: an emissive radiation source having a first spectrum; an optical element located to direct emissions from the emissive radiation source; a volumetric spectrum converter located to convert emissions directed from the emissive radiation source to emissions having a second spectrum different from the first spectrum; an optical reflector located about the converter; an output filter, the reflector being located to reflect the converter emissions towards the output filter; and a package body having an internal cavity containing the emissive radiation source, optical element, converter, reflector, and filter, wherein desired light radiates from the cavity through the filter.
