将所述灯体外壳11用塑料制成，并且在所述塑料外壳11上设有所述散热孔111，同时在所述塑料外壳11内设有散热器21。所述LED模组51固定于所述散热器21上，所述散热器21是用压铸铝制成，能起到很好地吸收LED模组51散发的热量并扩散开，也可用其他导热材料制造，如：车铝、陶瓷等；所述外壳为塑料制成，导热性差，而所述散热器21扩散开的热量则通过所述散热孔111与外界交换热量，故所述塑料外壳11上的温度并不高，同时有效保证了所述LED灯泡的散热，这样在人触碰到所述塑料外壳11时不会感觉到烫手，同时所述LED灯泡在更换、试用、维修等时候接触到所述塑料外壳11，不会烫伤皮肤，及防止因烫手而摔落，有效降低所述LED灯泡的维修率。
进一步地，所述塑料外壳11内具有套筒112，所述套筒112与所述塑料外壳11之间形成有容置空间113。本发明实施例的灯体100中，所述套筒112与所塑料外壳11一体成型，这样所述套筒112内可安置所述驱动电源41，同时可防止LED模组51散发的大部分热量孔散发到所述套筒112内部而影响驱动电源41使用寿命及可增加套筒112也能起到增强所述塑料外壳11强度的作用。
具体地，所述散热器21包括插装入所述容置空间113内的散热体211及连接于所述散热体211顶部并覆盖所述散热体211顶部的吸热体212。所述LED模组51可安装在所述吸热体212上，从而使所述LED模组51发出的热量更好地被所述散热器21吸收并扩散出去，提高了散热效率。
更具体地，所述散热器21的散热体211的外围凸设有若干间隔排列且沿所述套筒112的轴线方向延伸的散热肋2111，相邻散热肋2111之间形成有沟槽2112，所述沟槽2112与所述散热孔111位置对应。通过增加所述散热肋2111，扩大了散热面积，而设置于所述散热孔111对应的所述沟槽2112，增加了热交换的面积，散热效果更好。
再进一步地，所述塑料外壳11底部具有安装体114，所述塑料外壳11由所述安装体114朝向所述塑料外壳11顶部渐扩，所述容置空间113由所述塑料外壳11的底部至所述塑料外壳11的顶部逐渐扩张，所述散热肋2111相对于所述散热体211外围的高度由所述塑料外壳11的底部至所述塑料外壳11的顶部逐渐增加。通过安装体114可更好地与灯头31连接，根据不同的灯头31，所述安装体114可制成对应的配合安装结构，如根据目前长用的E27、E14灯头，安装体114可对应制成相应大小，并带外螺纹以便于安装。而所述容置空间113的渐扩和所述散热肋2111高度的增加都可增加散热面积和热交换面积，同时LED模组51安装在所述散热器21顶部的吸热体212上，这样所述散热体211越到顶部温度越高，而通过渐扩设计散热面积和热交换面积也是从越靠所述散热体211顶部面积越大，能更有效果散热。
具体地，所述塑料外壳11朝向其内部凸设有若干凸筋115，所述凸筋115沿着所述套筒112的轴线方向延伸，所述散热肋2111开设有凹槽2113，所述凸筋115对应容入所述凹槽2113内并于所述凸筋115与所述凹槽2113之间形成有散热通道2114。通过设置所述凸筋115可增加所述塑料外壳11的结构强度，同时所述散热肋2111上开设有所述凸筋115对应容入的所述凹槽2113可更好固定所述散热器21，而所述凸筋115与所述凹槽2113之间形成有散热通道2114则进一步增强散热效率。
进一步地，所述散热孔111为沿着所述套筒112轴线方向从所述散热体211底至所述散热体211顶部的长条状孔。通过所述长条状设置可使所述散热体211与外界的热交换面积更大，散热更好。
进一步地，所述套筒112上设置有沿所述套筒112的轴线方向延伸的至少一安装柱116，所述吸热体212上对应安装柱116位置设有安装孔2122，所述吸热体212上设有导线孔2121。这样可用螺钉等零件将LED模组51穿过所述安装孔2122直接固定在所述安装柱116上，可更好固定所述LED模组51，也能起到固定所述散热器21的作用，同时开设所述导线孔2121可方便所述LED模组51与所述驱动电源41进行电连接。
进一步地，所述套筒112内侧设置有用于供一驱动电源41卡设的电源固定柱117。所述的电源固定柱117可用来固定所述驱动电源41，防止电源的晃动产生损坏电源或电连接的接点松动，而影响产品质量。所述驱动电源41通过所述电源固定柱117固定于所述套筒112的内侧，让所述驱动电源41与外界物理隔绝，大大增强了人员使用安全性。
请参见图6-图7，本发明实施例公开的一种LED灯泡，包括灯头31，LED模组51，驱动电源41，灯罩61，所述LED灯泡还包括上述的灯体100，所述灯头31固定安装于所述灯体100的底部，所述驱动电源41安装于所述灯体100内并与所述LED模组51电连接，所述LED模组51固定于所述灯体100的顶部，所述灯罩61安装于所述灯体100顶部且罩设所述LED模组51。这种灯泡在更换、试用、维修等时候接触到所述的塑料外壳11，不会烫伤皮肤，及防止因烫手而摔落，有效降低灯泡的维修率。
所述驱动电源41上设有电连接端子411，所述驱动电源41固定在所述电源固定柱117上；所述LED模组51上开设有与所述导线孔2121对应的接线端子孔511和与所述安装孔2122对应的通孔512，所述LED模组51通过螺钉5121穿过所述通孔512及所述安装孔2122固定在所述塑料外壳11内的安装柱116上，通过电连接卡扣5111穿过所述接线端子孔511和所述导线孔2121卡在所述驱动电源41的电连接端子411上，这样安装简单，方便。优化地，所述LED模组51与所述吸热体212之间还可以加设导热板71，所述导热板71上开设有供所述电连接卡扣5111穿过的开口711及供所述螺钉5121穿过的小孔712，这样可更好地将所述LED模组51散发的热量传导到所述吸热体212上；为进一步增加导热性，可在所述导热板71与所述吸热体212之间涂抹导热硅胶，在所述LED模组51与所述导热板71之间也涂抹导热硅胶；本实施例也可在所述LED模组51与所述吸热体212之间直接涂抹导热硅胶。
请参见图7，本发明实施例中公开了三种灯头31，E27灯头312、E14灯头311及普通卡扣灯头313，通过所述塑料外壳11上的安装体114安装在所述灯头31中。将所述安装体114制成不同的大小和形状，可分别配合安装于所述E27灯头312、E14灯头311及普通卡扣灯头313中；进一步地，所述安装体114也可制成其他形状以适应配合安装于插拔式灯头，如G5.3、G10灯头，或其他灯头中。
综上所述，本发明实施例的灯体100，在用于LED灯泡时，这样就能使灯发出的热量通过散热器扩散散出，并通过所述散热孔111与外界进行热交换，有效保证了所述LED灯泡的散热，而所述塑料外壳11上的温度并不高，这样在人触碰到所述LED灯泡塑料外壳11时不会感觉到烫手。同时使用所述灯体100的LED灯泡，这种灯泡在更换、试用、维修等时候接触到所述的塑料外壳，不会烫伤皮肤，及防止因烫手而摔落，有效降低灯泡的维修率。
所述外壳11内具有套筒112，形成双层结构，使得用户可根据不同需求和技术发展灵活更换不同重量的散热器21，大大减少了金属铝的浪费，实实在在地节约资源，更直观地体现了LED灯节能环保的理念。
以上所述仅为本发明较佳的实施例而已，其结构并不限于上述列举的形状，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内。
