Description

可加大照射範圍的光源模組及燈具結構
本創作係有關一種可加大照射範圍的光源模組，尤指一種經特殊設計而可將光線導引至後方的光源模組及燈具結構。
一般之光源模組，藉由發光原理的不同，可分為許多型式，其中又以使用發光二極體作為其光源的光源模組，因為其具有良好的光轉換效率、波長固定以及光亮、光質可調整之特性而成為當今最被廣為使用的光源模組之一，除此之外，發光二極體更具有體積小、低發熱量且使用壽命較長之優勢。
然而，此類之光源模組即使擁有許多優點，卻仍有其先天之缺陷，是因光源本身不論其發光原理為何，皆仍受限於其照射範圍的方向性，一般來說，發光二極體光源的照射範圍約為120度，故其向前方直射的正向光最強，而側邊及後方之光源則相對較弱甚至無法照明，因此造成所謂的無效區域(或稱暗區)，為了加強該些無效區域之照明，經常就需要加設更多照明燈具以加強其照明效果，卻徒增了能源的浪費及消耗。
緣是，本創作人有感上述缺失之可改善，乃特潛心研究並配合學理之運用，終於提出一種設計合理且有效改善上述缺失之本創作。
本創作之主要目的，在於提供一種可加大照射範圍的光源模組及燈具結構，在妥善的設計之下，可將光源導引至其後方，減少無效區域，進而加大照射範圍。
為達成上述目的，本創作提供一種可加大照射範圍的光源模組，包括：一呈弧形的導光柱，該導光柱之表面形成有數個微結構；以及二發光二極體光源，與該導光柱之兩端相對應。
本創作另外提供一種燈具結構，包括：至少一呈弧形的導光柱，該導光柱之表面形成有數個微結構；至少二發光二極體光源，與所述之導光柱之兩端相對應；一散熱部，其側面設有數個散熱鰭片，該散熱部一端設有一電源座，該散熱部另一端設有一接觸面；以及一導熱部，其連接於該接觸面之上，該導熱部上裝設有所述之導光柱。
為使能更進一步瞭解本創作之特徵及技術內容，請參閱以下有關本創作之詳細說明及附圖，但是此等說明與所附圖示僅係用來說明本創作，而非對本創作的權利範圍作任何的限制。

圖4：為圖3導光柱內部之射光路徑的局部放大示意圖。
圖5A、5B、5C：為圖4導光柱上之微結構的局部放大示意圖。
請參閱圖1至圖3，本創作為一種可加大照射範圍的光源模組，包括有：一呈弧狀的導光柱1、數個形成於其表面的微結構11、設置於該導光柱1兩端的二容置空間12，以及與該導光柱1之兩端相對應的二發光二極體光源13。
該微結構11係為一系列經過計算及實驗後所設計而成之特殊構造，其形狀可呈角錐狀、圓錐狀、或者圓球狀(如圖5A、5B、5C所示)，且散布於該導光柱1之表面上。該二發光二極體光源13可容置於該導光柱1之二容置空間12中，並且電性連接於一導熱部3，該二發光二極體光源13係藉由該導熱部3驅動電力而產生照明光線，其光線行經該導光柱1並且受該些微結構11之影響，而產生各種如預期之效果諸如散射、折射、及反射等(如圖4所示)，其目的在於將光線逐步引導至該光源模組之後方，以減少無效區(暗區)，並加大其照射範圍。
本創作另外提供一種燈具結構，除包括上述光源模組外，進一步包括一散熱部2，其側面設有數片散熱鰭片21，該散熱部2之一端設有一電源座22，另一端設有一接觸面23；以及一導熱部3。
該些散熱鰭片21係相互間隔排列於該散熱部2之側面，其功用為增大與空氣間之接觸面積以加速對流，藉此加速散熱，該電源座22係為金屬材質，可連接於外接之電源並且導電，該接觸面23上設有一孔洞(圖略)，用以做電源之連接。
該導熱部3為一電路板，其一側設有數個發光二極體光源13，另一側則設有二條電源線(圖略)，該二條電源線係穿透過該孔洞並且電性連接於該電源座22，當形成通路時即可驅動該些發光二極體光源13以達到照明之目的。該導熱部3係連接於該接觸面23之上，藉此將該些發光二極體光源13所產生之熱能，經由熱傳導之方式，從該接觸面23將熱導引至該些散熱鰭片21以進行對流而散熱。本實施例中同時具有三組光源模組，該三組光源模組之排列方式呈等角度間隔設置，惟上述光源模組之數量及排列方式實際上並無特定限制。
本創作之可加大照射範圍的光源模組，藉由導光柱以及微結構之設計，可有效的引導光線以減少無效區，進而達到其加大照射範圍之目的，並且，該導光柱具有設計小巧之特色，故可一次安裝數個於該導熱部之上，以加大該光源模組之亮度。
以上所揭露者，僅為本創作較佳實施例而已，自不能以此限定本創作之權利範圍，因此依本創作申請範圍所作之均等變化或修飾，仍屬本創作所涵蓋之範圍。
