白光LED專利 1. 歐司朗 美國專利US 6066861 Wavelength-converting casting composition and its use (23-May-2000) Abstract (English) The wavelength-converting casting composition is based on a transparent epoxy casting resin with a luminous substance admixed. The composition is used in an electroluminescent component having a body that emits ultraviolet, blue or green light. An inorganic luminous substance pigment powder with luminous substance pigments is dispersed in the transparent epoxy casting resin. The luminous substance is a phosphorous group of the general formula A3 B5 X12 :M, and the luminous substance pigments have particle sizeslt;20 .mu.m and a mean grain diameter d50 lt;5 .mu.m. 中國專利 CN 1156029 C 波长变换填料及其应用 (30-Jun-2004) Abstract (Chinese) 基于一种掺有发光材料的透明环氧树脂的波长变换填料(5),它用于具有一个发紫外光、蓝光或绿光的发光体(1)的电致发光元件。在透明的环氧树脂中散布着一种具有出自通用式为Asub3/subBsub5/subXsub12/sub:M的磷族中发光色料颗粒的无机发光色料颗粒,及该无机发光色料颗粒具有≤20μm的粒度及平均颗粒直径dsub50/sub≤5μm。 US 6669866 B1: Luminous substance for a light source and light source associates therewith (30-Dec-2003) Abstract (English) A phosphor for light sources, the emission from which lies in the short-wave optical spectral region, as a garnet structure A3B5O12. It is activated with Ce, the second component B representing at least one of the elements Al and Ga, and the first component A is terbium or terbium together with at least one of the elements Y, Gd, La and/or Lu. In a preferred embodiment, a phosphor having a garnet of structure (Tb1?x?yRExCey)3(Al,Ga)5O12, where RE=Y, Gd, La and/or Lu; 0≦x≦0.5?y; 0y0.1 is used 2.日亞 Nichia 美國專利US5998925 Light emitting device having a nitride compound semiconductor and a phosphor containing a garnet fluorescent material (07-Dec-1999) Abstract (English) The white light emitting diode comprising a light emitting component using a semiconductor as a light emitting layer and a phosphor which absorbs a part of light emitted by the light emitting component and emits light of wavelength different from that of the absorbed l
