Description

1329182 九、發明說明： 【發明所屬之技術領域】 本發明係有關於一種照明裝置，尤指—種應用發 光二極體（L E D )照明、增加光源亮度以及使光源 更清晰的照明裝置。 【先前技術】
傳統的鎢絲燈，其所發出的光源為散射狀態，故 可對其週遭環境產生一定程度的亮度照明，但傳統的 鎢絲燈有耗電的缺點，有鑑於此，具有省電的發光二 極體（L E D )就逐漸取代傳統的鎢絲燈。 然而現有的發光二極體所發出的光線為直線狀， 散射狀，直線狀的光線僅能匯聚於一處，其他週 遭環境光線無法匯聚，就會顯得亮度不足。 有鑑於此，於是便有業者提出改進，如中華民國 專利證書號Μ 3 1 7 5 4 5 (公告日期民_ 9 6年8 月2 1日）係揭示有一種「使用發光二極體的燈罩 包^有電路板、發光二極體、反光體，該發光二極體 糸4固於該電路板的端面處，該反光體相對於電路 :發光二極體位置處形成有凹槽，凹槽的相對内壁面 土=，另：凹槽的底端面形成有可供發光二極體 貝牙的穿孔。錯此，可使發光二極體所發出的光 射狀，擴大光線照射的面積，增加亮度。 放 一雖然上述「使用發光二極體的燈二 的冗度’但其亚未能克服燈罩照射時會產生多重微影 5 1329182 的問題。發光一極體的封裝主要有點膠、灌封 二種，發光二極體黑點的問題在於上述製程中、ι 黑點會使發光二極體發射出來的光線 影響照明效果。 m成和， 緣是，本發明人有感於上述缺失之可改呈 潛心研究並配合學理之運用，終於提出-種；計合Ϊ 且有效改善上述缺失之本發明。 【發明内容】 本毛月之主要目的，係提供—種照明並姓 =”服發光二極體發光產生的 ； 大光線照射面積，增加光線的亮度與清晰度。也、 為了達成上述之目的’本發明提供一種昭明 3括：一燈罩；—承接座，其為呈筒狀，該承接 板安裝於該燈罩與該承接座之間；—反射層，^ = :該t罩與該導光板之間；以及複數個基板，其各里 有-發光二極體’該等基板安I於該承接座上。-本發明之㈣裝置有益絲 Π = 該承接座之間，用以混光= 多重微影，使光源更清晰；藉由該 罩與該導光板之間，使小面積的光源 而，“丨-:的大成大面積’進而在該導光板内重疊 而達U的效果’使點光源轉㈣面光源。 6 1329182 為使能更進-步了解本發明之特徵及技術内容 二：明之詳細說明與附圖，然而所附圖ί僅 仏乡考/、》兄月用，並非用來對本發明加以限制者。 【實施方式】 請參閱第一圖至第四圖’本發明係提供—
