518773 五、發明說明(2) 之缺失作進一步研究,並提出新構想且容易製造之一種白 光LED的製作方法,係以紫光(波長39〇〜41〇ηιη )來激發螢 光粉層使產生三波長白光LED。 本發明白光LED的製造方法,以選擇以波長390〜41 Onm 間f紫光來激發螢光粉產生白光,有別於先前技術以藍光 加黃色螢光粉(YAG )或用紫外光激發三基色螢光粉產生 三波長白光之技術。 本發明採用紫光的理由為在紫光範圍内美國的Cree公 司已可製作出波長390〜395 nm,發光功率高達2〇 mw以上之 L^D晶粒其發光效率與功率均比現今藍光或紫外光還要 高,另一因素為以紫光390〜410nm可被激發之螢光粉 (紅、藍、綠)均已被本人多次實驗後尋得,其中·· 紅色螢光粉可選用Y2〇2S : Eu,Gd 綠色螢光粉可選用ZnS : Cu,A1或(^“以2〇7 : π 藍色螢光粉可選用BaMgAl1Q017 : Eu 或(Sr、Ca、BaMg ) 10 (p〇4 ) 6C12 : Eu 將紅、藍、綠依適當的比例混合作調配即可得白光或 調各種色溫、色光。
