  • Patent number: 10290775
    Abstract: A semiconductor light emitting device comprising a light emitting layer disposed between an n-type region and a p-type region is combined with a ceramic layer which is disposed in a path of light emitted by the light emitting layer. The ceramic layer is composed of or includes a wavelength converting material such as a phosphor. Luminescent ceramic layers according to embodiments of the invention may be more robust and less sensitive to temperature than prior art phosphor layers. In addition, luminescent ceramics may exhibit less scattering and may therefore increase the conversion efficiency over prior art phosphor layers.

  • Patent number: 8496852
    Abstract: The invention relates to a phosphor in a polycrystalline ceramic structure and a light-emitting element provided with the same comprising a Light-Emitting Diode (LED) in which a composite structure of phosphor particles is embedded in a matrix, characterized in that the matrix is a ceramic composite structure comprising a polycrystalline ceramic alumina material, hereafter called luminescent ceramic matrix composite. This luminescent ceramic matrix composite can be made by the steps of converting a powder mixture of ceramic phosphor particles and alumina particles into a slurry, shaping the slurry into a compact, and applying a thermal treatment, optionally in combination with hot isostatic pressing into a polycrystalline phosphor-containing ceramic alumina composite structure.

  • Patent number: 7855449
    Abstract: A cooling device for cooling a light-emitting semiconductor device, such as a LED device (20), comprises a ceramic plate (15) having coolant-conveying channels (12) incorporated therein. The ceramic plate (15) is adapted for forming an integral part of the optical system of the light-emitting semiconductor device (20) and to cool a light-emitting portion (26) of the light-emitting semiconductor device (20). A method of forming a cooling device comprises the steps of forming a charge of ceramic particles, embossing the charge with a stamp to form coolant-conveying channels in the charge, hardening the charge, and providing a cover on top of the channels to seal them.
