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.
摘要翻译： 包括设置在n型区域和p型区域之间的发光层的半导体发光器件与设置在由发光层发射的光的路径中的陶瓷层组合。 陶瓷层由磷光体等波长转换材料构成或包含波长转换材料。 根据本发明的实施例的发光陶瓷层可以比现有技术的荧光体层更坚固并且对温度不太敏感。 此外，发光陶瓷可能表现出更少的散射，因此可以提高现有技术荧光体层的转换效率。
