Description

200914764 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，尤指一種應用發 光二極體（L £ 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， 而非散射狀，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。八 有鑑於此，於是便有業者提出改進，如中華民國 專利證書號M 3 1 7 5 4 5 (公告日㈣㈣6+8 月2 1日）係揭示有-種「使用發光二極體的 包，有電路板、發光二極體、反光體，該 係焊固於該電路板的端面處，狀光體相對於電路^ 的發光一極體位置處形成有凹槽，凹槽的相對内 土；二;另！!凹槽的底端面形成有可供發光二；體 貝牙的牙孔。精此，可使發光二極體所發 射狀，擴大光線照射的面積，增加亮度。 政 ▲雖然上述:使用發光：極體的“」能增 的焭度，但其亚未能克服燈罩照射時 、、' 才曰屋生多重微影
