Patent number: 10290775Abstract: 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.Type: GrantFiled: July 11, 2017Date of Patent: May 14, 2019Assignee: Lumileds LLCInventors: Gerd O. Mueller, Regina B. Mueller-Mach, Michael R. Krames, Peter J. Schmidt, Hans-Helmut Bechtel, Joerg Meyer, Jan de Graaf, Theo Arnold Kop
