下盖 1200支撑于下边缘 1150上， 并设置有与第一通腔 1160对应的第一通 孔 1212。 具体来说， 下盖 1200包括第一下盖体 1210与第二下盖体 1220。 第一 下盖体 1210包括一底壁 1211以及一端与底壁 1211连接且向下延伸的筒形侧壁 1213。 底壁 1211 支撑于第二下边缘 1152上。 第一通孔 1212形成于底壁 1211 上。 第二下盖体 1220设置于筒形侧壁 1213的外围， 且连接筒形侧壁 1213的另 一端， 并向上呈倒锥台形延伸。 并且， 第二下盖体 1220上间隔设置有用于接收 散热器 1100的第一下边缘 1151的第二插槽 1215。 一般的， 下盖由绝缘材料制 成。
固定板 1300支撑于散热器 1100的上边缘 1140上，并设置有与第一通腔 1160 对应的第二通孔 1310。 在本实施例中， 固定板 1300为铝板且具体支撑于散热器 1100的第二上边缘 1142上。
连接件 1400穿设于第一通孔 1212、 第一通腔 1160以及第二通孔 1310内， 并夹持下盖 1200和固定板 1300相对远离的两侧，以将下盖 1200和固定板 1300 固定于散热器 1100上。 在本实施例中， 连接件 1400为铆钉， 且包括第一支撑 部 1410、 第二支撑部 1420以及连接部 1430。 第一支撑部 1410支撑于下盖 1200 的底壁 1211 的远离固定板 1300的一侧， 第二支撑部 1420支撑于固定板 1300 的远离下盖 1200的一侧。 下盖 1200的底壁 1211上设置有用于接收第一支撑部 1410的第一凹部 1216 , 而固定板 1300上设置有用于接收第二支撑部 1420的第 二凹部 1320。 连接部 1430穿设于第一通孔 1212、 第一通腔 1160以及第二通孔 1310 内且连接第一支撑部 1410和第二支撑部 1420。 在本实施例中， 第二支撑 部 1420由连接部 1430挤压变形而成，而在其他实施例中，可为第一支撑部 1410 由连接部 1430挤压变形而成。 通过上述固定方式， 能够简单、 方便并且有效的 固定下盖 1200与散热器 1100。同时，由于下盖 1200和固定板 1300的夹持作用， 避免了散热片 1110之间的移位。

上盖 1700包括第一上盖体 1710与第二上盖体 1720。第一上盖体 1710呈环 形并支撑于散热器 1100的第一上边缘 1141上。 第一上盖体 1710上间隔设置有 用于接收第一上边缘 1141的第一插槽 1711。 第二上盖体 1720设置于第一上盖 体 1710的内侧边缘并向下延伸。 第二上盖体 1720与散热片 1110对应设置有扣 位 1721、 1170, 以通过扣位 1721、 1170将上盖 1700固定于散热器 1100上。 第 一上盖体 1710上进一步间隔设置有多个上通风孔 1730, 以促进散热片 1110之 间的空气流通。
接头 1800设置于下盖 1200上。 接头 1800和下盖 1200上对应设置有扣位 1810、 1214, 以使接头 1800相对于下盖 1200固定。 接头 1800与下盖 1200配 合形成一隔离腔 1820。电源基板 1900设置于隔离腔 1820内，进而与散热器 1100 隔离。
LED灯具组件进一步包括连接电源基板 1900和光源基板 1500的导线 1910。 连接件 1400设置有沿中心轴线延伸的第二通腔 1440, 导热贴 1530设置有第三 通孔 1531 , 导线 1910经第二通腔 1440与第三通孔 1531连接电源基板 1900和 光源基板 1500。
在另一个实施例中， 参见图 5与图 6 , 图 5是本发明的 LED灯具组件的第 二实施例的分解状态的立体示意图； 图 6是图 5中的 LED灯具组件的组装状态 的截面图。 本发明的 LED灯具组件的第二实施例中， LED灯具组件包括： 散热 器 2100、 下盖 2200、 固定板 2300、 连接件 2400、 光源基板 2500、 导热贴 2530、 透镜基板 2600、 上盖 2700、 接头 2800以及电源基板 2900。 本发明第二实施例 与第一实施例的结构的主要区别点在于： 上盖体 2700包括第一上盖体 2710与 第二上盖体 2720。 第一上盖体 2710呈环形并支撑于散热器 2100的第一上边缘 2141上。 第二上盖体 2720设置于第一上盖体 2710的内侧边缘并向下延伸。 第 二上盖体 2720设置有朝向中心轴线延伸的延伸部 2721 , 固定板 2500压制于延 伸部 2721上， 以将上盖 2700固定于散热器 2100。 在本实施例中， 固定板 2500 通过与第一实施例相同的方式固定于散热器 2100上。 在其他实施例中， 固定板 2500也可通过其他方式固定于散热器 2100上。
此外， LED灯具组件进一步包括用于隔离电源基板 2900和连接件 2400的 隔离垫 2240。 隔离垫 2240与下盖体 2200相配合， 将电源基板 2900与连接件 2400隔离。 并且， 隔离垫 2240上设置有第四通孔 2241 , 用于通过导线 2910。
参见图 7 , 图 7是本发明的 LED灯具组件的第三实施例的部分截面图。 在 本实施例中， 第一下盖体 3210上设置有第一下通风孔 3214和用于遮挡第一下 通风孔 3214的第一挡板 3215。 具体来说， 第一下通风孔 3214设置于第一下盖 体 3210的底壁 3211与筒形侧壁 3213的接合处。 第一挡板 3215设置底壁 3211 上且位于第一下通风孔 3214 内侧， 并向下延伸。 接头 3800上设置有第二下通 风孔 3830和用于遮挡第二下通风孔 3830的第二挡板 3840。 在本实施例中， 接 头 3800包括一倒锥台形侧壁 3820,第二下通风孔 3830和第二挡板 3840设置于 倒锥台形侧壁 3820上。 第二挡板 3840位于第二下通风孔 3830下侧， 并向上延 伸。 此种设计可加速散热， 并且防止外部物品通过第一下通风孔 3214、 第二下 通风孔 3830进入到 LED灯具组件的内部， 破坏电源基板 3900或造成短路。
本发明的有益效果是： 区别于现有技术的情况， 本发明能够简单、 方便并 且有效的固定下盖与散热器。
以上所述仅为本发明的实施例， 并非因此限制本发明的专利范围， 凡是利 用本发明说明书及附图内容所作的等效结构或等效流程变换， 或直接或间接运 用在其他相关的技术领域， 均同理包括在本发明的专利保护范围内。
