所谓的磷光体转换的发光器件(phosphor converted light emittingdevice)，其包含电致发光光源和至少部分吸收从该光源发出的光并重新发射较长波长的二级光(secondary light)的光转换元件，是现有技术已知的。最近，对含有CaAlSiN光转换磷光体材料的LED领域已经进行了研究，并且在这点上已经发现此类材料可以在LED中使用。实例例如描述于作为参考文献并入本文的EP05101834.9中。
然而，尽管该文献中描述的磷光材料显示出良好的光学特性，但是对于LED的要求，特别是在汽车中使用的LED，在多数应用中需要更高的效率和温度稳定性。
本发明的目的就是提供含有具有改进的效率和温度稳定性的CaAlSiN光转换材料的发光器件。
