Abstract:
A light generator comprises a light conversion device (10) and a light source (18) arranged to apply a light beam (L) to a light conversion element (20). The light conversion device (10) includes: an optoceramic (20) or other solid phosphor element comprising one or more phosphors embedded in a ceramic, glass, or other host; a metal heat sink (12); and a solder bond (40) attaching the optoceramic phosphor element (20) to the metal heat sink (12). The optoceramic phosphor element (20) does not undergo cracking in response to the light source (18) applying a light beam (L) of beam energy effective to heat the optoceramic phosphor element (20) to the phosphor quenching point.
Abstract:
A crucible having a heat treated body. The heat treated body comprises a composition including an oxide material, from 5 wt% to 50 wt% a nitride material, and optionally a sintering aid. A weight ratio of the nitride material to the oxide material ranges from 0.02:1 to 2.0:1. The heat treated body has an oxide material lattice structure with nitride material at least partially encapsulated therein.
