在该光源组件100中，塑料散热件2能够保证光源组件100的安全性；金属基板1和塑料散热件2能够有效散热，保证光源组件100的性能；并且金属基板1和塑料散热件2能够有效保证散热效果的前提下，可以将LED光源200设置的较为紧凑，不用将金属基板1和塑料散热件2额外放大，省去额外的布线等，以降低光源组件100的成本。因此，该光源组件100可以有效实现安全、性能与成本三者间的平衡。
金属基板1包括柔性电路板11和多个金属条形板12，LED光源200设置在金属条形板12上，柔性电路板11可以设置LED光源200，以补充边角的发光均匀，也可以不设置LED光源200。各金属条形板12的材质可以为铝，金属条形板12均为直线延伸的长条形。各金属条形板12依次排列，相邻的两个金属条形板12呈夹角设置，围成多边环形结构，例如三角形环形结构、五边形环形结构等。金属条形板12嵌设在嵌设槽21中，正面朝上，LED光源200设置在金属条形板12的正面，并且金属条形板12的正面两端分别设有铜箔。
柔性电路板11连接相邻的金属条形板12。每个光源组件100中的柔性电路板11可以一体加工，然后切割成多个所需形状的柔性电路板11。待切割成所需的柔性电路板11后，在柔性电路板11的两侧设置铜箔，柔性电路板11通过铜箔焊接在金属条形板12的正面。
金属条形板12的两端可以为斜边，相邻的两个金属条形板12接触或留有较小的间隙(例如1mm左右)。柔性电路板11与金属条形板12焊接后，通过金属条形板12支撑柔性电路板11，防止柔性电路板11变形而与金属条形板12脱离等。
塑料散热件2所使用的塑料与通常的相同，为加聚或缩聚反应聚合而成的高分子化合物。塑料散热件2大致呈多边环形一体式结构，塑料散热件2的中部设有一圈嵌设槽21，嵌设槽21的各边设置一个金属条形板12。
塑料散热件2上还设有操作槽22，操作槽22与嵌设槽21连接，通过操作槽22取放金属基板1。操作槽22可以位于嵌设槽21的拐角位置(或者说两个金属条形板12的夹角位置)。并且金属条形板12的侧边可以与柔性电路板11的侧边平齐或凸出于柔性电路板11，将金属基板1放置在嵌设槽21后，金属条形板12裸露在操作槽22中，以能够同时接触两个金属条形板12取放金属基板1，减少金属基板1变形失效的可能性。
塑料散热件2的内侧可以设置与嵌设槽21相连的收容槽23，吸顶灯的驱动电源安装在收容槽23中，以方便安装驱动电路。
如图1、图4所示，光源组件100还包括通过卡扣扣设在塑料散热件2上的上盖3。上盖3的形状大致与塑料散热件2的形状相同，为环形一体式结构，上盖3的侧边可以包裹塑料散热件2的侧边，上盖3同时覆盖塑料散热件2的收容槽23，以进一步提高安全性。上盖3可以为光学件，例如透镜。光学件也可以以多种方式设置，例如光学件设有若干透镜单元，各透镜单元自光线件上表面隆起并间隔排布为环形，透镜单元与LED光源一一对应，以便于控光。或者，光学件上还可以设有环形一体延伸的透镜部，透镜部自光学件上表面隆起并配置为双曲面，也便于实现控光。
上盖3的内侧或外侧可以设置安装部31，安装部31中固定有安装件，光源组件100通过安装件固定在吸顶灯底盘。此处优先选用安装部31设置在上盖3内侧，以减少光学组件的占用面积。安装部31可以为安装孔，安装孔包括吸附件安装孔311和螺钉安装孔312。当安装件为吸附件(例如吸铁磁)时，吸附件通过卡扣或固定螺钉固定在吸附件安装孔311中。当安装件为螺钉时，螺钉通过卡扣或固定螺钉固定在螺钉安装孔312中。通过上述方式设置安装部31，结构简单，安装方便。
本申请的LED光源模组使用于吸顶灯。LED光源200模组包括上述的光源组件100和设置在金属基板1上的LED光源200。在该LED光源200模组中，塑料散热件2能够保证光源组件100的安全性；金属基板1和塑料散热件2能够有效散热，保证光源组件100的性能；并且金属基板1和塑料散热件2能够有效保证散热效果的前提下，可以将LED光源200设置的较为紧凑，不用将金属基板1和塑料散热件2额外放大，以降低光源组件100的成本。因此，该光源组件100可以有效实现安全、性能与成本三者间的平衡。
本申请的吸顶灯包括上述的光源组件100、设置在金属基板1上的LED光源200和设置在塑料散热件2上的驱动电源，驱动电源具体设置在塑料散热件2的收容槽23中。在该吸顶灯中，塑料散热件2能够保证光源组件100的安全性；金属基板1和塑料散热件2能够有效散热，保证光源组件100的性能；并且金属基板1和塑料散热件2能够有效保证散热效果的前提下，可以将LED光源200设置的较为紧凑，不用将金属基板1和塑料散热件2额外放大，以降低光源组件100的成本。因此，该光源组件100可以有效实现安全、性能与成本三者间的平衡。
以上仅为本申请的实施例而已，并不用于限制本申请。对于本领域技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原理之内所作的任何修改、等同替换、改进等，均应包含在本申请的权利要求范围之内。
