在本发明实施例中，多个光源组件5和基板6均可以采用复合基材印制电路板，如采用CEM系列的覆铜板基材CEM-1(以木浆纤维纸或绵 浆纤维纸作为芯材增强材料，以玻璃纤维布作为表层增强材料，两者都浸以阻燃环氧树脂制成的覆铜板)和CEM-3(玻璃纤维纸作为芯材增强材料，以玻璃纤维布作为表层增强材料，两者都浸以阻燃环氧树脂制成的覆铜板)，该基板均具有较好的导热性能。当然也可以采用铝制的基板，或者采用环氧玻纤布印制电路板，如FR-4(覆铜箔阻燃性环氧玻璃布板)等材质的基板。另外，LED蜡烛灯100的泡壳3和灯体2均可以采用聚碳酸酯(PC)、聚对苯二甲酸丁二醇酯(PBT)等透光材质制成。本发明实施例对多个光源组件5、基板6、泡壳3以及灯体2的材质不做具体限定。
在本发明实施例中，多个光源组件5可以为三个光源组件、四个光源组件以及五个光源组件等，因此，围设形成的棱柱体分别可以是三棱柱体、四棱柱体、五棱柱体等棱柱体。并且，多个光源组件5之间可以采用焊接、插接、粘合等连接方式连接形成棱柱体，本发明实施例对光源组件5的数量以及光源组件5之间的连接方式不做具体限定，在本发明下文各实施例中，均以多个光源组件5为四个光源组件围设形成四棱柱体，且每个光源组件5上沿基板6的纵长方向均匀排布四个LED发光源7为例对LED蜡烛灯100进行介绍。
在本发明一实施例中，参见图2和图3，LED蜡烛灯100的光源组件5上端还可以设置有装饰帽12，装饰帽12与多个光源组件5卡扣连接。具体的连接方式可以为，装饰帽12的下端设置有多个第一卡扣121，多个光源组件5上部设置有与第一卡扣121相对应的小孔13，第一卡扣121卡接在小孔13内以将装饰帽12安装在多个光源组件5的上端。此外，为了实现装饰帽12与光源组件5的紧密连接，装饰帽12下端还设置有多个导向槽122，多个光源组件5中的每个光源组件5的上端均呈齿状结构14，导向槽122与齿状结构14咬合连接，从而可以使装饰帽12与光源组件5的连接更加牢固。在该实施例中，装饰帽12可以采用聚碳酸酯(PC)、聚对苯二甲酸丁二醇酯(PBT)等透光材质制成。
在本发明一可选实施例中，参见图4，为使散热连接部件9固定在灯体2内部，灯体2的内侧壁上设置有多个第二卡扣21和位于第二卡扣21 下端并沿灯体2的纵长方向设置的支撑部22，散热连接部件9的外边缘设置有与第二卡扣21相配合的卡槽91，散热连接部件9的卡槽91边缘卡接在第二卡扣21中，且散热连接部件9的下端面抵接在支撑部22的上端面，实现将散热连接部件9固定在灯体2的内部。另外，本发明实例还可以在灯体2的内侧壁上且位于第二卡扣21的下部设置多个第三卡扣23，用于将电源连接件10固定在灯体2内部，电源连接件10的外边缘设置有容纳槽101，灯体2内侧壁上的支撑部22穿过容纳槽101，且电源连接件10的外边缘卡接在第三卡扣23中，从而将电源连接件10固定在灯体2内部。然后，将电源连接件10与安装在灯体2下端的灯头1进行电性连接，该灯头1用于与外部供电电源电性连接。在该实施例中，灯头1与灯体2可以采用螺纹连接、套接、粘合等连接方式进行固定连接。
在本发明另一可选实施例中，为使散热连接部件9固定在灯体2内部，在散热连接部件9的外边缘设置第三卡扣，灯体2内侧壁上设置有与该第三卡扣相配合的卡边和位于卡边下部用于支撑散热连接部件9的支撑部22，灯体内侧壁的卡边卡接在散热连接部件9的第三卡扣上，并且散热连接部件9的下端面支撑在支撑部22上，从而实现将散热连接部件9固定在灯体2内部。
在本发明再一可选实施例中，为使散热连接部件9固定在灯体2内部，在灯体2的内侧壁上设置与散热连接部件9的边缘相配合的第一凹槽，通过直接将散热连接部件9的边缘卡设在第一凹槽中，即可实现将散热连接部件9固定在灯体2内部。另外，为使电源连接件10固定在灯体2内部，还可以在第一凹槽的下部且位于灯体2内侧壁上设置与电源连接件10的外边缘相配合的第二凹槽，通过直接将电源连接件10的边缘卡接在第二凹槽中，实现可将电源连接件10固定在灯体2内部。
本发明对各部件之间的连接方式不做具体限定，在不影响本发明的LED蜡烛灯100的使用性能的前提下，任何合理的连接方式均可。
对本发明实施例的LED蜡烛灯100进行温度测试得知，若LED蜡烛灯100的整灯功率为2.2W，得到的LED发光源7附近的温度为85℃， 而现有的普通灯的光源附近的温度一般都大于90℃。因此，本发明实施例无需使用专用的散热器，只需依靠多个光源组件5和散热连接部件9的连接即可实现LED蜡烛灯100的良好的内部热传导和辐射散热，从而大大减少了该LED蜡烛灯100的生产成本。
如图5所示，图5为本发明实施例的LED蜡烛灯100的光强分布图，其中，横坐标代表光照强度值，外边缘的坐标代表出光角度值，由该光强分布图可以直观地看出，在0-180度的角度范围内，LED蜡烛灯100具有光强值的角度范围为10-150度，即LED蜡烛灯100的出光角度为“150-10＝140度”，因此，本发明实施例的LED蜡烛灯100可以实现大角度的出光，进而，利用该实施例中的LED蜡烛灯100的水晶灯具也可以实现大角度配光，从而达到璀璨的视觉效果。
以上所述的具体实例，对本发明的目的、技术方案和有益效果进行了进一步详细说明，所应理解的是，以上所述仅为本发明的具体实施例而已，并不用于限制本发明，凡在本发明的精神和原则之内，所做的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
