Description

具有束框套環的LED燈泡
本發明係關於一種具有束框套環的LED燈泡設計，其係包括：散熱基座、散熱鰭片組、絕緣接頭、透光燈罩及束框套環，特別是指該束框套環係可向下卡止定位於散熱鰭片，向上則可固定扣合於燈罩，其能確保束框套環不會旋轉移動，並穩固扣接於透光燈罩。
習知LED燈泡，係包含散熱基座、散熱鰭片組、絕緣接頭、LED發光元件及透光燈罩等主要構件，散熱鰭片組係依附結合於散熱基座，其下端結合一絕緣接頭，該絕緣接頭係一具有螺合部的中空殻座，且套置結合一金屬導電螺套，而散熱基座於端面安裝設有LED發光元件或包含以複數LED串列組成的發光基板，進而通過散熱基座及散熱鰭片組，使LED發光元件所產生的熱溫可獲傳遞散熱。
習知LED燈泡的散熱鰭片組，係由複數散熱鰭片圍繞組成，因此，複數散熱鰭片位於上端的邊緣部份將會形成環繞狀的銳利邊壁，是以通常需再套置結合一束框套環，利用束框套環遮蓋包覆銳利的邊壁，藉此避免可能刺傷等危害情事。前述束框套環，一般僅簡易包覆於該環繞狀的銳利邊壁，因此容易發生旋轉移動而造成鬆動或脫落，除此，習知LED燈泡的透光燈罩，通常也都是通過膠黏方式而簡單黏接於束框套環，但黏膠日久可能發生質變，容易導致燈罩脫落，故以膠黏結合透光燈罩的效果並不理想。
上述習知LED燈泡的透光燈罩，係可實施為一透光的平板片形狀的燈罩，也可實施為一模擬燈泡形態的半圓形透光燈罩。而習知LED燈泡，例如：新型第M389826號、第M419035號、第M353292號、第M400660號、第M413817號、第M422646號、第M421458號、第M381724號等專利案所揭。
本發明之主要目的，乃在於提供一種具有束框套環的LED燈泡設計，該LED燈泡係包括散熱基座、散熱鰭片組、絕緣接頭、透光燈罩及束框套環，其中的束框套環係結合設於散熱鰭片組與透光燈罩之間，該束框套環係呈一環框形狀，其中的一側面係於環孔的內周邊設有複數個呈間隔相鄰的凸片，並於另一側面的外周邊設有複數個間隔相鄰的扣合缺口，其係利用複數個凸片可對應插入散熱鰭片之間的間隙，使束框套環產生定位作用，用以防止束框套環發生旋轉移動，而其另一側面的複數扣合缺口則可與燈罩形成適配對應的固定扣合，因此容易扣接且結合穩固，並解決習知以膠黏結合的諸多不便。
本發明之次要目的，乃在於提供一種具有束框套環的LED燈泡設計，其中的束框套環，係在具有複數凸片的同一側面，於外周邊並設有一環繞的內勾部，而利用該內勾部可供相對嵌合於複數散熱鰭片上端邊緣的嵌槽，以使束框套環亦可同時結合於散熱鰭片組。
茲依附圖實施例將本發明結構特徵及其他作用、目的 詳細說明如下：如第一圖至第三圖所示，本發明所為「具有束框套環的LED燈泡」，該LED燈泡10係包括：散熱基座1、散熱鰭片組2、絕緣接頭3、透光燈罩4及束框套環5，其中：散熱基座1，其端面係配置結合一包含複數LED 11串列組成的發光基板12，並開設適配的鑽孔13，以供線路安裝，該散熱基座1並與散熱鰭片組2形成環繞結合，使複數個散熱鰭片21係呈間隔相鄰而環繞結合於散熱基座1；散熱鰭片組2，係由複數個散熱鰭片21所環繞構成，各散熱鰭片21係可於上端邊緣均預設一嵌槽211；絕緣接頭3，為一習知元件，係依附結合於散熱鰭片組2的下端，其末端具有一標準規格的螺合部31，且套置結合一金屬導電螺套32；透光燈罩4，如實施例所示，其係呈半圓形的透光殼罩，並於透光燈罩4的周邊設有複數個凸出的扣片41，但所述的透光燈罩4，於必要時，亦可能實施為一呈平板片形狀的透光燈罩；束框套環5，係結合設於散熱鰭片組2與透光燈罩4之間，該束框套環5係呈一環框形狀，如第四圖所示，其中的一側面51係於環孔52的內周邊設有複數個間隔相鄰的凸片53，並於另一側面54(如第一圖)的外周邊設有複數個間隔相鄰的扣合缺口55，而前述的一側面51，亦可進一步於外周邊設有一環繞的內勾部56；依上述構件，其係將束框套環5的複數凸片53對應插 入各散熱鰭片21的間隙a(如第一圖)，使束框套環5產生定位，而可防止束框套環5發生旋轉移動，束框套環5的另一側面54，則以複數個扣合缺口55與透光燈罩4的複數扣片41形成適配對應的固定扣合，故能形成簡易扣接，且獲穩固結合。
如上述束框套環5的各凸片53，係分別對應插入各散熱鰭片21的間隙a，且各凸片53的兩側端係對應緊靠於各相鄰的散熱鰭片21，形成緊密穩固的插植結合，以確保該束框套環5沒有可旋轉移動的空隙。
如上述束框套環5於一側面51的外周邊所設呈環繞狀的內勾部56，其係可供嵌合於複數散熱鰭片21上端邊緣的相對嵌槽211，使束框套環5並可同時扣接結合於散熱鰭片組2。
依本發明設計，其主要係通過一束框套環5的構件改良，使該束框套環5得以向下卡止定位於散熱鰭片組2，向上則可固定扣合於透光燈罩4(如第六、七圖所示)，因此，不但能確保束框套環5不會發生旋轉移動，並可供穩固扣接透光燈罩4。又所述束框套環5如進一步設有一環繞的內勾部56，更可將該束框套環5亦同時扣接結合於散熱鰭片組2，故該束框套環5確實具有一舉多得的進步優點，也能解決習知以黏膠結合透光燈罩的不便與缺點。又，所述束框套環5的各凸片53，其內側面係緊密抵靠於散熱基座1的周緣面(如第七圖)，形成緊實的貼靠接觸，以利於熱溫的傳遞與散熱。
如上述本發明的束框套環5，其實施時係非常適合採 用金屬沖壓方式，成型為一金屬環框形狀的束框套環5，利用該金屬束框套環5可供卡止定位於散熱鰭片組2，並能扣合於透光燈罩4，或亦可同時扣接結合於散熱鰭片組2；但於必要時，所述的束框套環5，其亦可選用其他適當材質以供實施替代(如塑膠等)，故有關束框套環5的材質選用，自可適當替換，並無限制。
綜上所述，本發明所為LED燈泡的束框套環改良設計，其結構特徵已不同於習知，並具有實質上的進步功效，故應符合新穎性及進步性要件，敬祈 依法審查賜准專利，實感德便。
