照明系统和显示设备
摘要：
本发明涉及一种照明系统、包括该照明系统的照明器和显示设备(200)。该照明系统(100，101)包括发光二极管(D1，D2)、光出射窗(105)，和设置在该发光二极管和该光出射窗之间的发光层(120)。该发光二极管发射第一基色(72，75)的光。该发光层被设置在该发光二极管和光出射窗之间，用于将该发光二极管发射的一部分光转换成第二基色的光。该发光层包括至少含有镥、铈、硅和氮的石榴石发光材料(73)，或者包括两种石榴石发光材料的组合，其中一种石榴石发光材料(70)至少含有镥和铈，另一种石榴石发光材料(71，74)至少含有铈以及包含钇和钆的组中的至少一种元素。该光出射窗将由该照明系统产生的光朝显示设备射出。
摘要（英）：

The invention relates to an illumination system, a luminaire and a display-device (200) comprising the illumination system. The illumination system (100, 101) comprises a light emitting diode (D1, D2), a light exit window (105) and a luminescent layer (120) arranged between the light emitting diode and the light exit window. The light emitting diode emits light of a first primary color (72, 75). The luminescent layer is arranged between the light emitting diode and the light exit window for converting part of the light emitted by the light emitting diode into light of a second primary color. The luminescent layer comprises a garnet luminescent material comprising at least Lutetium, Cerium, Silicon and Nitrogen (73), or it comprises a combination of a garnet luminescent material comprisingat least Lutetium and Cerium (70) and a garnet luminescent material comprising at least Cerium and at least one element of the group comprising Yttrium and Gadolinium (71, 74). The light exit window emits light generated by the illumination system towards the display device.
