摘要： 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.

摘要： A light emission diode (LED) assembly, comprising a LED die (10), a phosphor layer (12), and a filter layer (14), wherein said filter layer (14) is developed in such a manner that light rays with a wavelength of about 400 nm to 500 nm, preferably of about 420 nm to 490 nm, emitted from the LED die (10) are at least partially reflected depending on their emission angle to the normal on the filter layer (14). With the inventive LED assembly it is possible to provide a LED assembly which solves the yellow ring problem without a reduction of the efficiency of the LED assembly.
