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.

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.

White light phosphor device

A light conversion device is disclosed. The light conversion device includes a substrate and a wavelength conversion element (). The wavelength conversion element () includes an inorganic binder, such as sodium silicate. Also disclosed are phosphor wheels and light engines including such phosphor wheels. Further disclosed are high-power laser projection display systems comprising a laser having a power of from about 60 W and about 300 W and a light conversion device. The use of an inorganic binder permits high thermal stability at reasonable cost.

Wavelength conversion elements formed from phosphors and dielectric interference particles dispersed in a host material, either in a single layer or in separate layers, are disclosed. Optical light conversion devices having such wavelength conversion elements, methods of making such wavelength conversion elements, and methods of using such wavelength conversion elements are also disclosed.

Reflective color correction for phosphor illumination systems

An optical device comprises two flat plates each having a reflective flat surface, and two flat spacer plates of thickness H each having a reflective sidewall. The flat plates and flat spacer plates are arranged as a stack with the reflective flat surfaces facing each other and the flat spacer plates arranged in a single plane and disposed between the two flat plates with the reflective sidewalls facing each other and with a gap between the two reflective sidewalls. The facing reflective flat surfaces and facing reflective sidewalls define a light tunnel passage with dimension H in the direction transverse to the single plane. The facing reflective sidewalls may be mutually parallel and spaced by a constant gap W to provide a light tunnel passage with constant cross-section H&#xd7;W, or may be oriented at an angle to provide a tapered light tunnel passage.

Phosphor elements comprising phosphors in a host material having a phosphorescence-emitting surface with surface nanostructures are disclosed. Phosphor wheels having such phosphor elements, methods of making such phosphor elements, and methods of using such phosphor elements are also disclosed.

Enhancement of output of optically pumped phosphor by use of surface nanostructures

A deposition system comprises a vacuum chamber having a cylindrical inner wall, a cylindrical parts carousel disposed concentrically inside the cylindrical inner wall of the vacuum chamber, and one or more deposition sources arranged to flow deposition material onto the cylindrical parts carousel. A cylindrical shutter assembly is disposed concentrically inside the cylindrical inner wall of the vacuum chamber, and has (1) a shuttered position in which the cylindrical shutter assembly blocks the one or more deposition sources from depositing onto the parts carousel and (2) an unshuttered position in which the cylindrical shutter assembly does not block the one or more deposition sources from depositing onto the parts carousel. A drive train rotates the cylindrical shutter assembly between the shuttered and unshuttered positions. The drive train not operatively connected to rotate the cylindrical parts carousel. The deposition sources may include inner and outer sputter sources.
