Description

Γ373591 六、發明說明： 【發明所屬之技術領域】 本發明關於一種發光二極體光源模組，尤指一種具散 熱功能及配光最佳化的發光二極體光源模組。 【先前技術】 有鑒於能源短缺的威脅與全球溫室效應的影響，使得 環保意識逐年提升，政府與國際團體紛紛向民眾宣導節能 減碳之觀念，由於發光二極體擁有省電、體積小、效率佳 等各項優點’再加上拜科技進步之賜，使得發光二極體亮 度提向、成本降低.，以發光二極體作為主要照明設備的技 術逐漸成熟，使得發光二極體燈具比日光燈管更亮、更省 電、更節能，而成.為新一代的照明趨勢。 然而’發光二極體所發出的光線具有指向性，故習用 發光二極體燈具所發出的光線往往不均勻且範圍小，例如 將發光二極體燈泡安裝於天花板上，其照明亮度明顯從燈 具下方的區域往外側降低’使得離燈具較遠之範圍顯得昏 暗許多’因此對於室内照明而言不甚理想，無法與傳統日 光燈相比擬》 再者’發光二極體在發光時會產生高熱，是故一般發 光二極體燈具皆具有金屬製的散熱鰭片來增加燈具熱傳導 的表面積，以幫助散熱。但在散熱過程中，發光二極體周 圍仍是高熱的空氣，故散熱效果在空氣缺乏對流的情況下 勢必大打折扣。 3 Γ373591 【發明内容】 由上述說明可知，既有發光二極體燈具之照明範圍過 小及空氣缺乏對流導致散熱效果不佳，實有進一步改良之 必要。 有鑑於此，本發明之主要目的在於提供一種具散熱功 能及配光最佳化的LED光源模組，其可藉調整出光方向並 可搭配透鏡而使配光最佳化，且結構上可使空氣產生對流 而幫助散熱。 欲達上述目的所使用之技術手段，係令該具散熱功能 及配光最佳化的L E D光源模組包含： 一散熱支架，係包含一上板、一 板及複數排熱管， 該上板係間隔穿設有複數貫孔；該下板對應上板之貫孔位 置亦形成有複數貫孔；該些熱排.管.係設於上、下板之間， 且每一熱排管係對應連接上、下板相對的貫孔； 一銘基板’係設於該下板之表面，該鋁基板上對應下 板之貫孔亦分別設有穿孔； 複數led組件，係分別裝設於鋁基板上兩相鄰的穿孔 之間；以及 兩旋轉組件’分別連接該散熱支架的兩端，其中散熱 支架可藉著旋轉組件進行旋轉而改變led組件的出光方 向。 由於下板附近的空氣溫度會因LED組件發光而升高， 相對地排熱管位於上板的另端開口附近空氣溫度較低，由 於熱空氣密度小於冷空氣，因此排熱管兩端開口相對產生 一使熱空氣持續從下板附近流入排熱管再流出上板之壓 4 1373591 力，藉此熱對流可使整個光源模組快速達到相對於習知LED 燈具更低溫的熱平衡，從而加強光源模組的散熱效果。 • 此外，旋轉组件的設置可使得光源模組裝設於一照明 裝置上時’可調筆其出光方向.，同時再搭配透鏡均勻出光， 加上光源模组化的設計而可由多個相同的光源模組配合不 同出光方向之調整’以符合不同的照明配光需求，.使配光 最佳化。’ . 综上所述，本發明之模組化設計在結構上可使空氣產 • 生對流而幫助散熱效果改善’且更提供配光角度之可調性。 因此本發明相較於既有技術擁有释著的功效增進，於符合 專利要件前提之下，爰依法提出申請。 【實施方式】 以下說明本發明之實施方式：請參考第—圖所示，係 本發明具散熱功能及配光最佳化的LED光源模組一較佳實 施例，其主要包含有一散熱支架（1〇)、一鋁基板（2〇)、複 • 數LED組件（30)及兩旋轉組件（40) » 進一步參考第二圖所示，該散熱支架（1〇)主要包含一 上板（11)、一下板（12)及複數排熱管（13)，該上板（11):間 隔穿設有複數貫孔（110);該下板（12)對應上板（11)之貫孔 (110)位置亦形成有複數貫孔（120) ·，該些熱排管（13)係μ 於上、下板（11)(12)之間’且每一熱排管（13)係對應連接上: 下板（11)(1 2)相對的貫孔（11 0)(120) » 該鋁基板（20)係設於該下板（12)之表面並内含金屬線 .路，其與下板（12)之間可藉著塗佈導熱膠之方式固定，該 5 1373591 鋁基板（20)上對應下板（12)之貫孔（12〇)亦分別設有穿孔 (200) ° 進一步參考第三圖所示，每一 LED組件（3〇)係裝設於 鋁基板（20)上兩相鄰的穿孔（2〇〇)之間本實施例中每一 LED組件要包含有一 LED單元（31)、一套筒（32)及 透鏡（33)，其中，該LED單元（31)係以表面黏著技術（SMT) 焊接於鋁基板（20)上，該套筒（32)係套設於LED單元（31) 上方，該透鏡（33)係設於套筒（32)内並裝設於LED單元（31) _ 上。可進一步令LED組件（30)包含一防水墊片（34)及一防 水塾圈（35)，令該防水塾片（34)夾設於套筒（32)與铭基板（2〇) 乏間，並藉由螺絲一同鎖固該套筒（32)、防水墊片（34)、 銘基板（20)以及下板（1 2>;該防水墊圈（35)則夾設於透鏡（33) 與套筒（32)之間，藉由該防水墊片（34)及防水墊圈（35)使得 LED組件（30)可防水。 如第一圖所示，該兩旋轉組件（40)分別連接該散熱支 架（1〇)的兩端，並可對應裝設於一照明裝置的電源接口上， 其中散熱支条（10)可藉著旋轉組件（4〇)進行旋轉而改變出 光方向，每一旋轉組件（4〇)包含一固定件（41)及一旋轉件 (42) ’該固定件（41)係用以裝設於一照明裝置的連接孔， 該旋轉件（42)係設於該固定件（41)上而可相對該固定件（41) 福轉，該旋轉件（42)係與散熱支架（10)一端組接，本實施 例中’該固定件（41)與該旋轉件（42)皆呈圓柱狀，其中該 旋轉件（42)與該固定件（41)共軸且徑長大於該固定件（41)。 參考第九圖所示，當應用於一照明裝置（2)時，可將多 數的本發明之發光二極體光源模組（1)並排於該照明裝置（2) 1373591
2光面上’Μ各發光二極體光源模组⑴係以兩端旋轉 .•件（40)的固定件（41)與照明裝置⑵組裝—起由於散熱 支架（10)可藉著旋轉組件（40)相對旋轉，而調整其上的LED 組件（30)的出光方向，只要舒备個恭止 罟野母個發光二極體光源模組（1) 的出光方向進行調整，即可使該昭 丨又必…奶哀置（2)相較於習知的 發光二極體照明裝置具備更寬的照明範圍與更均勻的照明 亮度，再者，除了同方向的筇Μ&要 ._ u刀π扪亚排叹置，亦可於照明裝置（2) 規劃不同區域提供設置安排’例如第十圖所示，部分光源
模組（1)係與其他並排的光源模組（1)成垂直設置；再如第 十一圖所示，該照明裝置（2)上係形成一中央平面（2〇〇)及 兩側面（201) ’該兩側面（2〇υ係分別從中央平面（2〇〇)兩側 斜向延伸，令多個光源模組（1)分布於該中央平面（2〇〇)及 側面（201)上，藉此提供更多元的照明設計；再者，由於前 述透鏡（33)的出光特性是將點光源特性的LED光源均勻分 布，使LED組件（30)可發出均勻且特定照明範圍之光源， 因此依據不同出光方向的光源模組（1)對應搭配不同出光特 性的透鏡（33)使用，藉此達到配光最佳化。 再者，如第三圖所示，當LED單元（31)點亮時，使得 下板（12)附近的空氣溫度升高’因熱空氣密度較小，再者， 排熱官（1 3)位於上板（11)的另端開口附近空氣溫度較低而 密度較大，因此排熱管（1 3)兩端相對產生一使熱空氣持續 從下板（12)附近流入排熱管（13)再流出上板（11)之壓力，藉 此熱對流可使整個光源模組快速達到相對於習知L E D燈且 更低溫的熱平衡，從而加強光源模組的散熱效果。 請參考第四圖及第五圖所示，且與前述第一圖實施例 1373591 (7)’最後藉由一 MCU管理器（8)統一設定工作電流，藉由 設定方波之伯空比，再提供給恒流驅動器的調光接腳以設 定每-光源模組之工作電流’可較為精確有效地調節每個 模組燈調的工作電流，配出更均勻之照明。 本發明所附圖式僅提供參考與說明用，並非用來對本 發明加以限制者。故舉凡運用本發明說明書及圖示内容所 為之等效結構變化，均同理包含於本發明之範圍内，合予 陳明。
