灯头的固定结构
技术领域
本实用新型有关灯头的固定结构，主要提升对灯头的固定效果，以及增加固定灯头便利性的固定结构。 
背景技术
按，早期日光灯的灯管的材质大多为玻璃，且日光灯管内部含有少量的水银，故，在拿取或装设上需极为小心，因不小心打破日光灯管的话，其内部的水银流出会对环境造成伤害，且人体不小心碰触到或吸附到的话，也会造成中毒现象；且传统日光灯虽便宜，但其废弃物有汞污染或易碎等缺点。 
然，目前的日光灯新一代的改良，采用发光二极管(LED)来发光，其结构上也跟早期的日光灯设计是一样的，以能适用早期的灯架。 
如图1所示，一般发光二极管灯管由一灯壳11、发光二极管元件12，以及两个插头13所组成，该灯壳11由一长条状的灯壳座14与一长条状的透光罩15相嵌合构成一管状结构体，该灯壳11设有一容置空间18，以供容置发光二极管元件的基板17，而各灯头13则藉由螺丝19锁固方式固定于该灯壳座14二端，以达到固定的效果；惟，藉由螺丝19的固定，需要工具才得以进行拆卸或锁固。 
实用新型内容
本实用新型所解决的技术问题即在针对灯头的固定结构加以改良，藉以提升对灯头的固定效果，以及增加固定灯头便利性的固定结构。 
本实用新型所采用的技术手段如下所述。 
为达上揭目的，本实用新型的灯头利用固定结构分别定位设置于灯管的二末端；其中：该灯管靠近二末端处设有至少一穿孔，该灯头相对各穿孔形成有定位孔，而该固定结构设有二弹性臂以及连接二弹性臂的压抵部，而二弹性臂末端则形成有卡掣部。 
该卡掣部可依序穿入于穿孔及定位孔，而使该灯头得以套设固定于该灯管，可提升对灯头的固定效果，以及增加固定灯头的便利性。 
依据上述主要结构特征，所述灯管至少设有：一灯壳座、一透光罩以及光源模组，该灯壳座一断面盖呈半圆状的结构体，其相对于半圆的内部形成有一凹谷状的容置空间，该容置空间底面设有一固定部，而各穿孔则相对于该固定部上方，而该透光罩则与该灯壳座的容置空间开口相盖合，该光源模组则设有一电路板及复数设于该电路板上的发光元件，利用该压抵部可使该电路板定位于该灯壳座的固定部上。 
依据上述主要结构特征，所述灯壳座的固定部与该电路板之间可增设有导热胶。 
依据上述主要结构特征，所述灯头设有二电性端子，而于该灯头内侧则分别设有一导电端子，该导电端子与该电性端子连接，而该光源模组的电路板二端设有一连接座，该连接座设有一壳体，该壳体设有至少一插槽，该插槽内设有端子以及与该端子连接的导电片，该导电片并延伸至该壳体侧边，以供与该电路板电性连接，而该插槽则可供各灯头的导电端子插接而形成导通。 
依据上述主要结构特征，所述灯壳座在其相对于半圆的外部设有若干散热鳍片。 
本实用新型所产生的有益效果如下所述。 
1、本实用新型所述灯头的固定结构可提升对灯头的固定效果，以及增加固定灯头的便利性。 
2、本实用新型可利用简单插接动作即可构成灯头与灯管的组装，使其具有易组装、易维修、易检测、易更换零元件，进而增加实用性。

具体实施方式
如图2为本实用新型灯头与灯管的结构立体图，以及图3为本实用新型灯头与灯管的结构分解图所示，本实用新型的灯头20利用固定结构30分别定位设置于灯管40的二末端；其中：该灯管40靠近二末端处设有至少一穿孔41，该灯头20相对各穿孔41形成有定位孔21，而该固定结构30设有二弹性臂31以及连接二弹性臂31的压抵部32，而二弹性臂31末端则形成有卡掣部33。 
整体组装时，该卡掣部33可依序穿入于穿孔41及定位孔21，而使该灯头20得以套设固定于该灯管40，可提升对灯头20的固定效果，以及增加固定灯头的便利性；当裕将灯头20自该灯管40拆卸时，仅需将卡掣部33内压使其脱离该定位孔21，则可将该灯头20与该灯管40相互分离。 
再者，该灯管40至少设有：一灯壳座42、一透光罩43以及光源模组44，该灯壳座42一断面盖呈半圆状的结构体，其相对于半圆的内部形成有一凹谷状的容置空间，该容置空间底面设有一固定部421，而各穿孔41则相对于该固定部421上方，该灯壳座42在其相对于半圆的外部设有若干散热鳍片422，而该透光罩43则与该灯壳座42的容置空间开口相盖合，该光源模组44则设有一电路板441及复数设于该电路板441上的发光元件442，请同时参阅图4所示，利用该压抵部32可使该电路板441定位于该灯壳座的固定部421上，以改良习有电路板需利用螺丝锁固的方式，而可增加光源模组的组装弹性，以及提升对光源模组的固定效果；当然，该灯壳座的固定部与该电路板之间可增设有导热胶，可进一步增加固定效果。 
另外，该灯头20设有二电性端子22，而于该灯头内侧则分别设有一导电端子23，该导电端子23与该电性端子22一体制成且相互连接，而该光源模组的电路板441二端设有一连接座50，该连接座50设有一壳体51，该壳体51设有至少一插槽511，该插槽511内设有端子512以及与该端子512连接的导电片513，该导电片513并延伸至该壳体侧边，以供与该电路板441电性连接，而该插槽511则可供各灯头的导电端子23插接而形成导通；当本实用新型的灯管插入习用灯座结构时，该电性端子22以及导电端子23藉由该连接座50与电路板441形成一电流回路，使发光元件442因接收到电力而发光发亮。故本实用新型可利用简单插接动作即可构成灯头与灯管的组装，使其具有易组装、易维修、易检测、易更换零元件，进而增加实用性。
