Abstract: A white light source includes a light source and a phosphor conversion component. The light source emits short wavelength light peaked at a peak wavelength of 570 nanometers or shorter. The phosphor conversion component includes a light conversion layer comprising a phosphor effective to convert the short wavelength light to converted light. The light conversion layer includes light passages comprising openings or passage material that does not comprise the phosphor and is light transmissive for the short wavelength light. The light source is disposed respective to the phosphor conversion component so as to illuminate the light conversion layer with the emitted short wavelength light and to pass the short wavelength light through the light passages.

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.
