ABSTRACT:
A light emitting device uses a source of exciting radiation such as an light emitting diode to excite a photo luminescent material to provide a source of visible light. The photo luminescent material is loaded into a low density material such as a xerogel or an aerogel which is adjacent the source of exciting radiation.
