Abstract
A light generator comprises a light conversion device and a light source arranged to apply a light beam to the light conversion element. The light conversion device includes an optoceramic or other solid phosphor element comprising one or more phosphors embedded in a ceramic, glass, or other host, a metal heat sink, and a solder bond attaching the optoceramic phosphor element to the metal heat sink. The optoceramic phosphor element does not undergo cracking in response to the light source applying a light beam of beam energy effective to heat the optoceramic phosphor element to the phosphor quenching point.
