具体实施方式：
图1为本发明的发光装置1的立体图。图2为本发明的发光装置1的分解图。图3为本发明的光源插座40与发光元件60的分解图。图4为本发明的光源插座40及发光元件60的俯视图，为了清楚的目的，仅于图4中绘制了两个发光元件60。发光装置1可为一灯泡，用以插置于一灯具(图未示)。
发光装置1包括一导电接头10、一基座20、一电源模组30、一导电组件50、一光源插座40、一导电组件50、多个发光元件60以及一罩体70。
导电接头10可为一金属壳体。导电接头10的外侧壁211可具有螺纹11，用以锁固于一灯具的电源插座(图未示)。导电接头10具有一连接槽12。
基座20设置于导电接头10。基座20的底部插置于导电接头10的连接槽12。基座20可由绝缘材质所制成，例如塑胶。于一些实施例中，绝缘材质中可加入导热粉，例如碳材料、无机导热粒子、或是金属粒子。基座20的顶部具有一容置槽21。
电源模组30设置于导电接头10的连接槽12内，并位于导电接头10与 基座20之间。电源模组30包括一电源本体31与多个电极元件32。电源本体31设置于导电接头10的连接槽12。电源本体31电性连接于导电接头10。电极元件32连接于电源本体31，且穿过基座20的底部至容置槽21。电极元件32可为一线性延伸的柱状结构。于一些实施例中，电极元件32的横向剖面为一圆形或一矩形。
一般而言，灯具的电源插座所提供的电源为电压110V或220V的交流电，因此电源本体31可将交流电转换为直流电及发光元件60所适用的电压。于一些实施例中，电源本体31包括一变压器以及一整流器等电子元件(图未示)。
光源插座40设置于基座20。光源插座40可由绝缘材质所制成，例如塑胶。于一些实施例中，绝缘材质中可加入导热粉，例如碳材料、无机导热粒子、或是金属粒子。导电组件50埋入于光源插座40内(如图4所示)，导电组件50用以电性连接导电接头10、电源模组30与发光元件60。
发光元件60插置于光源插座40。发光元件60可大致垂直于光源插座40。发光元件60作为一光源用以产生光线。于本实施例中，如图1、2所示，发光元件60的底部邻近于光源插座40的顶面41的边缘，发光元件60的顶部邻近于顶面41中央的上方，可增加发光装置1的美观。
罩体70设置于导电接头10，并包覆光源插座40与发光元件60。换句话说，光源插座40与发光元件60位于罩体70的内部。罩体70可由透明材质所制成，例如玻璃。罩体70底部的外表面可固定于容置槽21的侧壁211，换句话说，罩体70的底部位于容置槽21的侧壁211与光源插座40之间。于本实施例中，罩体70可与光源插座40以及发光元件60相互间隔。
如图3及图4所示，光源插座40具有多个光源插槽42。光源插槽42形成于顶面41。光源插槽42的数目可为5个以上，于本实施例中，光源插槽42的数目为6个。每一光源插槽42具有位于顶面41的一开口421。开口421 相对于顶面41的中心C1呈放射状排列。
开口421可为狭长状，于一些实施例中，开口421为一矩形。开口421具有一端部422与一端部423。端部422邻近于中心C1，且端部423邻近于顶面41的边缘。端部422可沿一圆形路径P1排列，于一些实施例中，圆形路径P1为一正圆形或是一椭圆形。
端部422与中心C1排列于一直线L1上，且开口421的纵向D1与直线L1之间夹有一锐角A1，锐角A1大约为15度至60度之间。于本实施例中，锐角A1大约为45度。
发光元件60插置于光源插座40的光源插槽42。发光元件60可大致垂直于光源插座40的顶面41。图5为本发明的发光元件60的立体图。发光元件60包括一电路板61、多个发光单元62以及一荧光层63。电路板61用以插置于光源插座40的光源插槽42。于本实施例中，电路板61为一长条状结构，且可大致沿一插接方向D2延伸。
于一些实施例中，电路板61可为一透明电路板61。因此发光单元62所产生的光线可穿透电路板61，进而增加发光装置1的整体亮度。于一些实施例中，电路板61可为玻璃基板、金属基板或陶瓷基板。于一些实施例中，上述玻璃基板可为三氧化二铝玻璃基板，上述金属基板可为铝氧化基板或覆铜铝基板，且上述陶瓷基板可为三氧化二铝陶瓷基板。
电路板61具有多个导电接点611。导电接点611设置于电路板61的正面612，且位于电路板61的底部。导电接点611可具有一正极导电接点与一负极导电接点。
发光单元62可为发光二极管，用以产生光线。发光单元62设置于电路板61的正面612。于本实施例中，发光单元62大致沿插接方向D2排列于电路板61，且与导电接点611电性连接。
荧光层63覆盖于正面612与发光单元62。荧光层63并不覆盖于导电接 点611以及正面612的底部。于一些实施例中，荧光层63并不覆盖于电路板61的侧面614及/或相反于正面612的背面613。
于一些实施例中，电路板61为一透明电路板61，且发光单元62为发出波长为蓝光的发光二极管。发光单元62的正面所发出的蓝光通过荧光层63后激发为另一波长的光线(例如黄光或是白光)。由于电路板61为透明电路板61，因此发光单元62的背面(贴附于电路板61的正面612)所发出的蓝光则不会通过荧光层63，而直接由电路板61的背面613，或由电路板61内部经过反射后经由电路板61的侧面614射出。因此电路板61的背面613以及侧面614会发出蓝光。
如图4、5所示，经由发光元件60以及光源插槽42的排列，电路板61的背面613、以及邻近于中心C1的侧面614所发出蓝光大部分会通过另一发光单元62的荧光层63，并经由荧光层63激发为另一波长的光线(例如黄光或是白光)。因此，于本实施例中，荧光层63可仅覆盖于电路板61的正面612，可节省的发光元件60的制作时间与成本，以使发光装置1具有良好的发光均匀度。
另如图4与图6A所示，导电组件50包括多个导电元件51，导电元件51以光源插座40的中心C1呈放射状排列，于一些实施例中，导电元件51位于一平面上。
导电元件51包括一连接部511、一导电端512、一导电端513以及一电极端514。连接部511埋入于光源插座40内。连接部511连接导电端512、513、与电极端514。连接部511、及导电端512、513为板状结构。于本实施例中，如图4所示，部分的导电元件51不包括电极端514。
同一个导电元件51的导电端512位于光源插槽42之内，且导电端513位于另一光源插槽42内。如图4与图6A所示，导电端512、513突出于光源插槽42的一第一侧面424。位于同一光源插槽42内的导电端512、513可分 别为一正极导电端与一负极导电端。导电端512、513与光源插槽42的一第二侧面425相互间隔。第二侧面425朝向且相对于第一侧面424。
图6A至图6C为本发明的发光装置1于一组装阶段的示意图。如图6A与图6B所示，发光元件60沿插接方向D2经由开口421移动至光源插槽42内部，且光源插槽42可沿插接方向D2延伸。导电端512与连接部511大致垂直于电路板61。换句话说，导电端512与连接部511大致垂直于插接方向D2。
如图6B与图6C与所示，于电路板61插置于光源插槽42的过程中，当电路板61接触于导电端512、513后，电路板61继续沿插接方向D2移动进而推挤导电端512、513，以使导电端512、513产生弹性变形或弯折。导电端512产生弹性变形或弯折可形成圆角(rounded corner)。
当电路板61插置于如图6C所示的插接位置时，通过导电端512、513的弹性变形所产生得弹力使得导电端512、513分别抵接于导电接点611，使得电路板61抵靠于第二侧面425，并与第一侧面424相互间隔。换句话说，通过上述弹力使得电路板61夹持于第二侧面425和导电端512、513之间。因此，通过上述的弹力亦可将发光元件60固定于光源插座40，且发光元件60不易拔出于光源插座40的光源插槽42。
通过发光元件60以插置的方式组合于光源插座40，可简化发光装置1的组装。此外，通过仅以电路板61的底部插接于光源插座40，可得到良好的散热效果，因此不需设置大体积的金属散热器，进而能节省制作的成本。
图7为本发明的一金属板件B1的俯视图。导电组件50可由一金属板件B1经由冲压等制程所形成。金属板件B1包括多个导电组件50与金属框B10。导电组件50连接于金属框B10。于本实施例中，可将光源插座40以射出成型的方式形成于金属板上的导电组件50。
之后，再将每一导电元件51经由裁切等方式与金属框B10分离，即可使导电组件50精确地埋入光源插座40。借此，发光装置1的制作方式，可简化导电组件50组装于光源插座40的过程。
图8为本发明的发光装置1的部分分解图。图9为本发明的光源插座40的仰视图。光源插座40更具有一底面43、多个一扣合部44、多个限位槽45以及多个电极插槽46。底面43相反于顶面41。光源插槽42可穿过底面43。
扣合部44设置于底面43，邻近于且位于底面43的边缘。基座20设置于底面43，且基座20的底部具有一扣合孔22、一固定槽23、多个卡勾部25。扣合孔22连通于容置槽21与固定槽23。扣合孔22对应于扣合部44。当光源插座40组合于基座20时，扣合部44穿过并固定于扣合孔22，借以将光源插座40固定于基座20。
限位槽45形成于底面43。于本实施例中，限位槽45为弧形，配合于底面43的边缘的形状，且邻近于底面43的边缘。基座20还包括多个限位块24，位于容置槽21的底部。当光源插座40组合于基座20时，限位块24位于限位槽45内，以防止光源插座40相对于基座20旋转。
通过上述的基座20与光源插座40之间的扣合结构，能使得光源插座40能轻易地组装于基座20。
此外，基座20还包括多个卡勾部25，位于固定槽23内，电源本体31(如图2所示)可扣合于卡勾部25，且通过卡勾部25固定于固定槽23内。
图10为本发明的电极元件32插置于电极插槽46的示意图。如图8至10所示，电极插槽46形成于底面43，且邻近于底面43的边缘。导电组件50的电极端514突出于电极插槽46的一第一侧壁461。连接部511大致垂直于电极元件32。基座20具有多个电极穿孔26，连通于容置槽21与固定槽23。电极穿孔26的位置对应于电极插槽46。
当电源模组30组装于基座20的固定槽23时，电极元件32穿过电极穿孔26插置于电极插槽46。如同图6A至图6B的原理，当电极元件32未插入电极插槽46时，电极端514大致垂直于电极元件32延伸，且平行于连接部511。当电极元件32沿插接方向D3移动，进而推挤电极端514，以使电极端514产生弹性变形或弯折。电极端514产生弹性变形或弯折可形成圆角。
通过电极端514的弹性变形所产生得弹力使得电极端514抵接于电极元件32，并使得电极元件32抵靠于相对于第一侧壁461的第二侧壁462且与第一侧壁461相互间隔。换句话说，通过上述弹力使得电极元件32夹持于第二侧壁462和电极端514之间。
于本实施例中，电极元件32具有多个扣合槽321，电极端514抵接于扣合槽321内。扣合槽321可环绕于电极元件32的侧壁。于一些实施例中，扣合槽321并未朝向第二侧壁462。另外，于插接方向D3上排列的多个扣合槽321，可配合不同光源插座40内的电极端514的位置，亦可避免于制作上的公差，导致电极端514无法抵接于扣合槽321内。
如图10所示，电极端514的端面515朝向扣合槽321的一侧面，因此电源模组30沿插接方向D3的相反方向移动时，电极端514的端面515抵顶扣合槽321的侧面，由于电极端514所形成的弯曲结构使得电极元件32难以沿插接方向D3的相反抽出于电极插槽46。
因此，通过上述的结构，可将电源模组30固定于光源插座40，且电极元件32不易拔出于光源插座40的电极插槽46。
图11为本发明的另一实施例的电极元件32插置于电极插槽46的示意图。于此实施例中，导电元件51具有另一电极端514突出于第二侧壁462，且抵接于扣合槽321内。电极元件32位于两电极端514的中央，且与第一侧壁461和第二侧壁462相互间隔。换句话说，通过电极端514的弹力，电极元件32被两电极端514所夹持。通过上述的结构，亦可使电极元件32不 易拔出于光源插座40的电极插槽46。
上述已揭露的技术特征能以任何适当方式与一或多个已揭露的实施例相互组合、修饰、置换或转用，并不限定于特定的实施例。
综上所述，本发明的发光装置可通过将发光元件以及电源模组以插置的方式组合于光源插座，借以简化发光装置的组装。此外，由于具有发光单元的电路板以插置的方式组合于光源插座，而不需大体积的金属散热器，进而能节省制作的成本。再者，通过光源插槽与发光元件的排列方式，能使得光源插座具有良好的发光均匀度。
以上所述仅为本发明较佳实施例，然其并非用以限定本发明的范围，任何熟悉本项技术的人员，在不脱离本发明的精神和范围内，可在此基础上做进一步的改进和变化，因此本发明的保护范围当以本申请的权利要求书所界定的范围为准。
