以下在实施方式中详细叙述本发明之详细特征以及优点，其内容足以使任何熟习相关技艺者了解本发明之技术内容并据以实施，且根据本说明书所揭露之内容、权利要求及图式，任何熟习相关技艺者可轻易地理解本创作相关之目的及优点。
具体实施方式
为详细说明技术方案的技术内容、构造特征、所实现目的及效果，以下结合具体实施例并配合附图详予说明。
请参阅图1至图4，图1为根据本发明的高散热效能的灯具1的一实施例的外观示意图。图2为根据本发明的高散热效能的灯具11的一实施例的分解示意图。图3为根据本发明的高散热效能的灯具11的电源模组13的一实施例的外观示意图。图4为根据本发明的高散热效能的灯具11的一实施例的剖面示意图。
如图1、图2所示，高散热效能的灯具1包含灯管11、灯条12、电源模组13、电源座14以及二外盖15。
灯管11两端分别具一开口111；灯条12位于所述灯管11内；电源模组13设置于所述灯条12的一侧，电性连接所述灯条12。所述电源模组13包含一个或一个个以上的散热电基板，在此实施例中为二个，分别界定为第一电基板131及第二电基板132，所述第二电基板132位于所述第一电基板131上方，经由电性连接件电性连接。
特别说明的是，第一电基板131及第二电基板132使用的是金属基板，达成散热目的，并且第一电基板131及第二电基板132不但可以作为表贴式器件(SMT)，亦可以作为直插式分立器件(插装件)。不同于一般产品仅仅是光源板使用铝基板在材料生产加工工艺的区别。
电源座14设置于所述灯条12的另一侧，与所述灯条12电性连接；二外盖15分别位于所述开口111的外侧，所述外盖15与所述灯管11结合，封盖所述开口111。在此实施例中，所述的第一基板131为金属制基板，如此，有助于散热。如图2、图3所示，所述第一电基板131与第二电基板132之间设置有电性连接件134，第一基板131经由电性连接134件电性连接于第二基板132则更有助于扩大散热的效果。所述第二基板132亦为金属制基板，此外，所述电性连接件亦可以为具导电及散热效果的金属所制造，结构如接脚或插针。在此实施例中，第二电基板132上设置有多个电子元件133。
以上述灯具的结构设计，相较于传统的技术，其是单一使用铝基板，并不足以降低电子元件133的发热温度。而本发明经由金属电基板的结构设计，除了本身可以散热外，还经由电性连接件电性连接其他金属电基板，将电子元件所发出的热量分散于两个以上的电基板，以增加散热面积，达到散热效果良好的目的。
如图2所示，高效率灯具进一步包含塑性管体16，设置于所述灯管11内，两端对应所述开口111具有洞口161，所述灯条12位于所述塑性管体16内； 所述灯条12包含基板121与多个发光元件122，多个发光元件122设置于所述基板121上。设置于所述灯管11内，两端对应所述开口111具有洞口161，所述灯条12位于所述塑性管体16内。
进一步说明，在此实施例中，所述塑性管体16内部设有定位架162，所述灯条12设置在定位架162上。
请再参阅图1、图2及图4，所述二外盖15分别包含电接部151及管体部152，所述电接部151连接所述管体部152，所述电源模组13及所述电源座14分别位于所述管体部152内。在此实施例中，所述管体部152为长管形状，所述管体部152盖接在所述灯管11一端上。然而本发明并不以此为限。
此外，所述电接部151包含二导电柱1512，所述电接部151的顶面壁上开设有二孔洞1511，所述二导电柱1512分别插接在所述孔洞1511上。在一些实施例中，所述导电柱1512为铜柱。
根据本发明的高散热效能的灯具一个或多个实施例，使用金属制的电基板以达到散热的目的。在一些实施例中，二个或二个以上的电基板，经由电性连接件电性连接以增加散热的面积，使发热的电子元件跟其他电子元件之间的温度更加均匀，不会因为个别元件发热温度高造成局部的热差异或温度差异，且不必对个别发热大的元件进行降温处理，如此可以节约材料及工时成本。
换言之，传统技术是使用单独的铝制基板，并不足以降低电子元件的高温度。本发明的一实施例中则是经由电性连接件，电气连接的将所述的热量分散在二个以上的金属制的电基板上(即散热电基板的堆叠数量不限于两层)，以增加散热面积，达到良好的散热效果。
需要说明的是，尽管在本文中已经对上述各实施例进行了描述，但并非因此限制本发明的专利保护范围。因此，基于本发明的创新理念，对本文所述实施例进行的变更和修改，或利用本发明说明书及附图内容所作的等效结构或等效流程变换，直接或间接地将以上技术方案运用在其他相关的技术领 域，均包括在本发明专利的保护范围之内。
