如图 2、 图 3和图 5所示， 本实施例中第一壳体 7的第一后壳 7b 和第二壳体 8的前壳 8a均向外均延伸有安装凸柱 16， 安装凸柱 16内设 有朝向壳体内部的螺丝安装孔。 LED灯珠组 1和 LED电子元器件 3均设有 安装位，该安装位与安装凸柱 16内设有朝向壳体内部的螺丝安装孔相对 应； LED灯珠组 1紧密接触第一后壳 7b的内壁固定于第一后壳 7b的内壁 上； LED电子元器件 3紧密接触前壳 8a的内壁固定于前壳 8a的内壁。在 该结构中， 由于 LED灯珠组 1和 LED电子元器件 3紧密接触壳体的内壁， 将散发的热量直接通过金属壳体传导到壳体外的散热片 9， 由散热片 9 和散热装置 10散发。
如图 2和图 3所示，本实施例中第一壳体 7的第一后壳 7b的散热装 置 10为一面设有栅格状散热片 9的铝合金板，铝合金板的另一面设有凹 孔， 所述凹孔与第一后壳 7b向外均延伸的安装凸柱 16相配合。 在该结 构中， 由于 LED灯珠组 1较 LED电子元器件 3的散热更大， 增设本散热 装置 10可以更有效的使 LED灯珠组 1散热，使 LED灯珠的使用寿命更长。
如图 1和图 2所示，本实施例中第一壳体 7水平方向的两端和垂直方 向的两端均设有拼接装置 17;拼接装置 17分为设在第一壳体 7—端的拼 接螺杆 17a， 拼接螺杆末端设有紧固手轮； 拼接装置 17分为设在第一壳 体 7另一端的与拼接螺杆 17a可契合的卡槽 17b。 拼接时， 将一个 LED 灯具的第一壳体 7—端的拼接螺杆 17a契合上另一个 LED灯具的第一壳 体 7—端的卡槽 17b，再通过旋转紧固手轮将两个 LED灯具拼接起来。在 该结构中， 拼接简单方便， 可实现多个 LED灯具的拼接。
