如图3所示，容置体100设置有一开口端110，容置体100可呈球泡型等形状，容置体100可由透明或半透明材料一体成型，例如采用玻璃材料或塑胶材料一体成型。
电源壳200经开口端110插置于容置体100并可通过激光焊接工艺进行密封连接，电源壳200用于容置电源模块202，电源壳200可采用塑胶材料一体成型。
光源基板300与电源模块202电连接，如图4至图6所示，光源基板300包括端面LED基板310和一体连接于端面LED基板310两相对侧边的侧面LED基板320，侧面LED基板320相对端面LED基板310弯折围合以形成筒状发光体300并与电源壳200的底部相固定。端面LED基板310可呈正多边形，例如端面LED基板310可呈正六边形。
灯头400与容置体100或电源壳200相配合，并通过转接套410护盖容置体100和电源壳200的结合处。
如图10和图11所示，电源壳200的底部设有套接部220，套接部220的外表面设有热熔柱222，热熔柱222用于接收侧面LED基板320的固定孔325挂置并通过热熔固定。
具体而言，如图4至图6所示，侧面LED基板320可包括第一侧板321、第二侧板322以及第三侧板323，第二侧板322与端面LED基板310连接，第一侧板321和第三侧板323与端面LED基板310相断开并连接于第二侧板322的两侧边。
其中，第一侧板321与第二侧板322之间以及第二侧板322与第三侧板323之间可设有多个切槽324，多个切槽324用于方便第一侧板321和第三侧板323相对第二侧板322弯折。
为了配合热熔固定，第二侧板322上设有固定孔325，固定孔325用于接收热熔柱222插设以进行热熔固定。
第一侧板321和/或第三侧板323的内部设有冲切区326，冲切区326内延伸有接电触片327，接电触片327用于相对第一侧板321和/或第三侧板323弯折以在筒状发光体300内部进行电连接。
在另一实施例中，如图7至图9所示，第一侧板321和/或第三侧板323的边缘设有冲切开口328，冲切开口328内延伸有接电触片329，接电触片329用于相对第一侧板321和/或第三侧板323弯折以在筒状发光体300的端部进行电连接。
在本发明实施例中，端面LED基板310和侧面LED基板320均包括铝基板301和设于铝基板301上的多个LED 302，铝基板301的厚度可为0.6毫米等厚度，其冲压制作方便、易于弯折、散热效果极好，其中，铝基板301上印设有油墨层和导电线路，由于不涉及发明点所在，此处不作赘述。
本发明提供的灯具10采用液冷方式进行散热，容置体100用于盛装冷却介质120以对光源基板300进行散热，冷却介质120为绝缘液体，例如采用绝缘油。
如图10和图11所示，电源壳200还包括主体部210和连接部230。
其中，主体部210设有法兰211，法兰211用于压扣在开口端110上，套接部220设于主体部210的一端，套接部220用于接收筒状发光体300套接并通过热熔柱222热熔变形以固定筒状发光体300；连接部230设于主体部210的另一端，用于连接灯头400。
在本发明实施例中，套接部220的端面与端面LED基板310的形状相对应，套接部220的端面可呈正多边形，例如图10中所示，套接部220的端面呈正六边形，套接部220两相对的侧面设有热熔柱222，每一侧面上的热熔柱222的数量为至少一个，例如图10中所示的两个。
此外，套接部220的外侧设有挡板224，挡板224与套接部220形成插套间隙以接收筒状发光体300套接。
由于两个侧面LED基板320相对端面LED基板310弯折围合后并不具有固定状态，仍是相对的松散状态，此处具体是指端面LED基板310两侧边的两块第一侧板321和两块第三侧板323在弯折围合后的位置，即图9中所标示的315处，因此，为了防止两个侧面LED基板320在装配后会松脱，本发明对应设置有挡板224，挡板224可呈V型状，用于挡护侧面LED基板320弯折后的围合处315（见图9），以使得筒状发光体300在不采用焊接固定或者扣接固定的情况下仍不会散开，若采用焊接固定，则会使得灯具10的装配复杂，而采用扣接固定则需要设计对应的卡扣结构。
如图10和图11所示，电源壳200包括容置仓201和设于容置仓201底部的过线孔226，容置仓201用于容置电源模块202，过线孔226用于接收导线（图未示）贯穿以将电源模块202与筒状发光体300电连接。
在本发明具体实施例中，容置仓201内通过灌胶密封电源模块202和过线孔226，通过灌胶方式可以获得极好的密封效果，防止内部冷却介质120流出。
请一并参阅图4至图9，本发明实施例还提供一种光源基板300，该光源基板300包括端面LED基板310和一体连接于端面LED基板310两相对侧边的侧面LED基板320，侧面LED基板320用于相对端面LED基板310弯折围合以形成筒状发光体300。
根据本发明一具体实施例，端面LED基板310可呈正多边形，例如图4和图7中所示，端面LED基板310呈正六边形。
侧面LED基板320可包括第一侧板321、第二侧板322以及第三侧板323，第二侧板322与端面LED基板310连接，第一侧板321和第三侧板323与端面LED基板310相断开并连接于第二侧板322的两侧边。制造该光源基板300时，只需将图中端面LED基板310与侧面LED基板320之间少部不需要的板材切除即可，材料浪费相对较少。
其中，第一侧板321与第二侧板322之间以及第二侧板322与第三侧板323之间设有多个切槽324，多个切槽324用于方便第一侧板321和第三侧板323相对第二侧板322弯折。
为了配合热熔固定，第二侧板322上设有固定孔325，固定孔325用于接收热熔柱222插设以进行热熔固定。
为了进行电连接，如图4至图6所示，第一侧板321和/或第三侧板323的内部设有冲切区326，冲切区326内延伸有接电触片327，接电触片327用于相对第一侧板321和/或第三侧板323弯折以在筒状发光体300内部进行电连接。
在另一实施例中，如图7至图9所示，第一侧板321和/或第三侧板323的边缘设有冲切开口328，冲切开口328内延伸有接电触片329，接电触片329用于相对第一侧板321和/或第三侧板323弯折以在筒状发光体300的端部进行电连接。
在本发明实施例中，端面LED基板310和侧面LED基板320均包括铝基板301和设于铝基板301上的多个LED 302，铝基板301的厚度可为0.6毫米等厚度，其冲压制作方便、易于弯折、散热效果极好，其中，铝基板301上印设有油墨层和导电线路，由于不涉及发明点所在，此处不作赘述。
本发明实施例还提供一种灯具10，该灯具10包括前述的光源基板300。
请一并参阅图1至图3及图10和图11，本发明还提供一种电源壳200，该电源壳200包括主体部210、套接部220以及连接部230。
其中，套接部220设于主体部210的一端，套接部220的外表面设有热熔柱222，套接部220用于接收筒状发光体300套接并通过热熔柱222热熔变形以固定筒状发光体300；
连接部230设于主体部210的另一端，用于连接灯头400。
在本发明具体实施例中，套接部220的端面可呈正多边形，例如图10中所示，套接部220的端面呈正六边形。
套接部220两相对的侧面设有热熔柱222，每一侧面上的热熔柱222的数量为至少一个，具体可为两个或三个等。
此外，套接部220的外侧设有挡板224，挡板224与套接部220形成插套间隙以接收筒状发光体300套接。
请一并参阅图4至图9，由于两个侧面LED基板320相对端面LED基板310弯折围合后并不具有固定状态，仍是相对的松散状态，此处具体是指端面LED基板310两侧边的两块第一侧板321和两块第三侧板323在弯折围合后的位置，即图9中所标示的315处，因此，为了防止两个侧面LED基板320在装配后会松脱，本发明对应设置有挡板224，挡板224可呈V型状，用于挡护侧面LED基板320弯折后的围合处315（见图9），以使得筒状发光体300在不采用焊接固定或者扣接固定的情况下仍不会散开，若采用焊接固定，则会使得灯具10的装配复杂，而采用扣接固定则需要设计对应的卡扣结构。
如图11所示，电源壳200包括容置仓201和设于容置仓201底部的过线孔226，容置仓201用于容置电源模块202，过线孔226用于接收导线贯穿以将电源模块202与筒状发光体300电连接。
