摘要	This invention is related to LED Light Extraction for optoelectronic applications. More particularly the invention relates to (A1, Ga, In)N combined with optimized optics and phosphor layer for highly efficient (A1, Ga, In)N based light emitting diodes applications, and its fabrication method. A further extension is the general combination of a shaped high refractive index light extraction material combined with a shaped optical element.
其他摘要	本发明涉及用于光电应用的LED光提取。更具体地说，本发明涉及与用于高效（Al，Ga，In）N发光二极管应用的优化的光学器件和磷光体层结合的（A1，Ga，In）N及其制造方法。进一步的延伸是成形高折射率光提取材料与成形光学元件结合的一般组合。
主权项	A Light Emitting Diode (LED), comprising: an LED chip, emitting light at a first wavelength region; an encapsulation layer, coupled to the LED chip, wherein the encapsulation layer is transparent at the first wavelength region; and a phosphor layer, coupled to the encapsulation layer and distant from the LED chip, the phosphor layer converting the light emitted by the LED chip in the first wavelength region to light in at least a second wavelength region, wherein at least a portion of a surface of the phosphor layer is textured.
