Description
本發明係關於一種發光二極體裝置,特別是關於一種利用提高混光效果而擴大發光晶片之分選範圍之發光二極體裝置。
由於在發光晶片製造上存在著種種之變異,使製成之發光晶片間在亮度或發光波長等特性上會存在著些許之差異。利用發光晶片作為照明之初,以單顆應用者居多,亮度或顏色之控制要求不高,因此發光晶片間之差異影響不明顯。
然而,將複數個發光晶片排列成陣列來加以運用時,若未經分選過程,在整體上可能導致亮度或顏色不均勻。為了解決此一問題,將發光晶片按照一些特性參數進行分類,在測試過後,分別於不同特性參數上給予一分類值(bin codes)。在使用時,選取相近分類值之發光晶片,如此即可避免發光晶片排成陣列後,所造成之不均勻之問題。可是,分選發光晶片,會增加成本支出,而且,隨著大照明面積之運用及對照明品質之要求,分類值之選擇範圍必須相對地限縮,此無疑造成使用上之不便,更導致成本大幅上揚。
另,螢光粉的效率會因環境溫度之升高而使其效率降低,且因發光晶片屬高熱通量之發光元件,倘若散熱模組設計不佳或環境條件控制不良,則會影響到螢光粉的效
率,因此若要避免螢光粉受熱之影響,則需對螢光粉做進一步之保護。
又,以發光晶片作為背光模組之光源時,與其他照明應用不同之處在於要讓一方向上之發光角度需較大,以進行混光;而同時也要限制另一方向上之發光角度,使較多之入射光能進入背光模組,以提高亮度。
綜合所述,經分選後組合成之發光晶片陣列,可確保發光品質,然而成本高,不符合經濟效益。螢光粉受溫度之影響而效率降低,然習知之設計中仍無防範之道。再者,發光晶片陣列應用在背光模組時,在不同方向上需有不同之發光角度,而習知技藝中,仍未見相對應之技術開發。
本發明提供一種發光二極體裝置,其係利用光擴散之手段,提高混光效果,藉此加大發光晶片之分選範圍。此外,利用膠體將螢光粉層隔開,使其較不易受熱之影響,而能保持一定之效率。又,在不同方向上利用光擴散與集光手段,使發光二極體裝置在不同方向上具有不同之發光角度。
本發明一實施例之一種發光二極體裝置包含一具一電路圖案之基板、一設置於該基板上之反光層、至少一設置於該反光層之發光晶片、一圍繞於該發光晶片之反射器、一覆蓋於該發光晶片之膠體及一設置於該膠體上方且用於均勻混光之一螢光粉層。該發光晶片具一導電部,該基板之該電路圖案與該導電部相連接,該發光晶片藉此獲取驅
動電源。該反射器包含一位於反射器出口之出光面及位於反射器內緣之一第一反射面。
本發明另一實施例之一種發光二極體裝置包含一具一電路圖案之基板、一設置於該基板上之反光層、至少一設置於該反光層之發光晶片、一圍繞於該發光晶片之反射器及一具一表面且覆蓋於該發光晶片之螢光膠體。該發光晶片具一導電部,該基板之該電路圖案與該導電部相連接,該發光晶片藉此獲取驅動電源。該反射器包含一位於反射器出口之出光面及位於反射器內緣之一第一反射面。該螢光膠體係螢光粉與矽膠混合製成。
圖1顯示本發明第一實施範例之發光二極體裝置100之俯視圖。圖2係圖1沿X1-X'1剖面線之剖面圖。發光二極體裝置100包含一具一電路圖案104之基板102a、一設置於基板102a上之反光層106、至少一設置於該反光層106之發光晶片108、一圍繞於該發光晶片108之反射器110、一覆蓋於發光晶片108之膠體112a及一設置於該膠體112a上方且用於均勻混光之一螢光粉層114。發光晶片108具一導電部109,基板102a之電路圖案104與該導電部相連接,藉此以提供發光晶片108驅動電源。
該反射器110包含一位於反射器出口之出光面116及位於反射器內緣之一第一反射面118。第一反射面118係一傾斜面,利用第一反射面118可使發光晶片108之側向光往出光面116反射。反射器110係設置於反光層106上,然此非為必
要,其亦可設置於基板102a上。於本實施例中,該第一反射面118與基板102a間之角度θ1
包含30°至80°間。反射器110具反射發光晶片108之發光之能力,故其材料係為一反射材料。反射器110之材質可包含金屬材質或非金屬材質。金屬材質可包含如鈦、金、鋁、銀、鉑、鈀或前述金屬之複合金屬等。非金屬材質可選自聚鄰苯二甲醯胺、陶瓷、聚碳酸酯。非金屬材質亦可為摻雜具反射效果之材料之高分子材料,其中該摻雜之材料包含具反射效果之非金屬材料或金屬材料。
反光層106具至少一通孔120,電路圖案104經由通孔120連接發光晶片108之導電部109。電路圖案104中設置與外部電源連接之接點,使外部電源得藉由電路圖案104提供發光晶片108驅動電源。反光層106具高反射率,其可為一金屬反光層,金屬反光層之材質可包含鈦、金、鋁、銀、鉑、鈀或前述金屬之複合金屬;反光層106之材料亦可為無機材料,包含二氧化鈦(titanium dioxide)、氧化鋁(aluminum oxide)、氧化鋅(zinc oxide)、硫化鋅(zinc sulfide)、硫酸鋇(barium sulfate)、氧化銻(antimony oxide)、氧化鎂(magnesium oxide)、氟化鎂(magnesium fluoride)、碳酸鈣(calcium carbonate)、硼氮化物(boron nitride)或上述之組合。
本實施例中,螢光粉層114設置於膠體112a表面上,且收容於反射器110內。相較於習知技藝,由於膠體112a將螢光粉層114與基板102a隔離,發光晶片108之發熱不易影響到
螢光粉層114,而使其可維持一穩定之發光效率。螢光粉層114之構成可為螢光粉與矽膠之混合或為螢光粉與環氧樹脂之混合。
反射器110之出光面116可設置至少一微結構光學膜片122,微結構光學膜片122與螢光粉層114間可具一間隙124(如圖2所示),或者兩者間為無間隙之密合狀。微結構光學膜片122之設置係用於提供集光與擴散等複合式光學效果,其可以複數具單一光學效果之光學膜所組成,或為具集光與擴散等複合式光學效果之單一光學膜。
膠體112a包含矽膠及環氧樹脂,而膠體112a中可嵌置光擴散粒子,使通過之光線可均勻擴散。一般而言,若使用粒徑較小之光擴散粒子,混入之光擴散粒子之重量比需較高,如此才可具較好之混光效果。於本案實施例中,膠體112a中可嵌置重量比為0.1%至20%之光擴散粒子。較佳地,當使用粒徑為1至30微米之光擴散粒子時,混入之重量比為0.2%至10%。
基板102a之材質可選自玻璃、陶瓷、電木、環氧樹脂、聚對苯二甲酸乙二醇酯、聚亞醯胺、氰酯、雙順丁烯二酸醯亞胺/三氮阱、玻璃纖維之耐燃性積層板材第四級材質(FR4)及玻璃纖維之耐燃性積層板材第五級材質(FR5)所組群組之其中一者。

該反光層106之發光晶片108、一圍繞於該發光晶片108之反射器110及一覆蓋於發光晶片108之膠體112a。反射器110包含一位於反射器出口之出光面116,而至少一微結構光學膜片122設置於出光面116。一螢光粉層114塗覆於微結構光學膜片122上,且設置於微結構光學膜片122與出光面116間,藉以促進均勻混光。由於螢光粉層114遠離基板102a,使其不易受發光晶片108之發熱影響,而能維持一穩定之發光效率。於本實施例中,膠體112a與螢光粉層114間留存一間隙124。於其他實施例中,膠體112a與螢光粉層114間亦可密合貼附。膠體112a中可嵌置光擴散粒子,使通過之光線可均勻擴散。
