Composite fluorescent ceramic, preparation method and light-emitting
The invention provides a composite fluorescent ceramic, a preparation method and a light-emitting, the composite fluorescent ceramic comprises a plurality of groups of fluorescent ceramics arranged on a plane, each group of fluorescent ceramics comprises at least one strip-shaped fluorescent ceramic sheet, and various fluorescent ceramic sheets are alternately arranged on the plane. The composite fluorescent ceramic is arranged on an excitation surface perpendicular to a light-emitting chip to obtain the light-emitting device, light of different colors can be obtained after the composite fluorescent ceramic is excited by the same light-emitting chip, and uniform white light is formed after the light of different colors is combined. The composite fluorescent ceramic has the advantages of high transparency, flexible structural design, controllable spectrum adjustment, good color rendering property, high luminous efficiency, good heat-conducting property and the like, and effectively overcomes the defects of poor color rendering property, low luminous efficiency and the like of the existing fluorescent ceramic applied to the high-power white light LED/LD.
本发明提供了一种复合荧光陶瓷、制备方法及发光器件，所述复合荧光陶瓷包括多组在平面上排列的荧光陶瓷，每组所述荧光陶瓷包括至少一种带状的荧光陶瓷片，各种所述荧光陶瓷片在平面上交替排列。将本发明的复合荧光陶瓷设置于垂直于发光芯片的激发面获得发光器件，复合荧光陶瓷中经由同一种发光芯片激发后可得到不同颜色的光，不同颜色的光组合后成均匀的白光，复合荧光陶瓷具有透明度高、结构设计灵活、光谱调节可控、显色性好、发光效率高和导热性能好等优点，有效解决现应用于高功率白光LED/LD的荧光陶瓷显色性差和发光效率低等缺点。
