灯体 1包括散热器 11、 LED光源板 12以及驱动 13。 LED光源板 12固 定于散热器 11 , 散热器 11与外部空气相连。散热器 11包括基板 110以及与 基板 110—体的外壁 111。 LED光源板 12固定于散热器 11的基板 110， 散 热器 11通过外壁 111与外部空气相连。 灯罩 3固定于散热器 11和反射器 4 之间。散热器 4的外壁 111具有突出基板 110形成的固持壁 112。固持壁 112 呈环形从而形成容置空间 1120。 LED光源板 12位于容置空间 1120内， 灯 罩 3的连接部 33抵接散热器 11的基板 110， 且连接部 33的外侧与固持壁 112抵接。驱动 13位于散热器 11内部， 灯头 2包覆驱动 13的一部分， 包括 位于内部的绝缘壳体 21以及与其他对接装置连接的连接头 22。绝缘壳体 21 具有若干卡扣装置 210， 散热器 11内壁上具有若干凸起 113， 绝缘壳体 21 通过卡扣装置 210与凸起 113的卡接而固定于散热器 11。本实施例中，连接 头 22与散热器 11组装成一体， 其他实施例中， 连接头 22也可以与散热器 11一体成型。
LED光源板 12为环形平板， 具有位于 LED光源板 12中心的通孔 120。 LED光源板 12面向反射器 4的一侧具有若干 LED光源 121。 本实施例中， LED光源 121环绕分布于反射器 4第一端 41的周围， 反射器 4的第一端 41 穿过 LED光源板 12的通孔 120固定于散热器 11。其他实施例中， 也可以增 加设置分布于反射器 4的第一端 41中心的 LED光源， 而将反射器 4固定于 LED光源板 12即可。
灯罩 3、 反射器 4、盖板 7组装时， 先将灯罩 3安装于灯体 1。然后将反 射器 4自灯罩 3的球形部 32一端插入灯罩 3中。 再用螺母 6将反射器 4固 定于灯体 1， 此时由于反射器 4对灯罩 3产生一朝向灯体 1的力， 而灯体 1 对灯罩 3产生朝向反射器 4第二端 42的力， 使得反射器 4将灯罩 3卡持于 反射器 4第二端 42与灯体 1之间。 最后再将盖板 7卡扣于反射器 4上。 当 LED灯 100具有信号接收器时， 先将信号接收器安装于反射器 4或盖板 Ί 上后再将盖板 7卡扣于反射器 4。
本发明 LED灯 100通过反射器 4的设置使得 LED光源 121的部分光线 被发射后， 向 LED灯 100的侧面和灯体 1方向射出， 且灯罩 3的侧出光面 积较大， 使得 LED灯 100的侧发光效率更高。 LED灯 100的配光角度可达 到 300度以上。 并且本发明 LED灯 100利用反射器 4卡扣灯罩 3的结构， 使得 LED灯 100安装方便， 且反射器 4在灯罩 3内部的结构可根据需要灵 活设计。 盖板 7的结构解决了 LED灯 100反射器 4第二端 42的黑斑问题， 使得外观上更加美观。将信号接收器安装于盖板 7和反射器 4的容置空间内， 使得信号接收器不会影响 LED灯 100的出光， 又很好的利用了空间， 并且 信号接收器 100位于 LED灯 100最靠近用户的一端， 接收效果更加良好。
