本实施例中的固定支架 46包括固定杆 17和平面框架， 在 LED模块化光源上 的组合连接架 7上设有固定杆通孔， 固定杆 17贯穿于该固定杆通孔中而使数个 LED模块化光源连接为一体， LED模块化光源 11通过固定杆 17两端固定在固定 支架 46上， LED模块化光源 11在固定支架 46上呈规则分布， 由 LED模块化光 源 11组合成的条状光源体之间具有散热间隙 47。
实施例 12
如图 17所示， 本实施例与实施例 11的不同之处在于： 固定支架 46采用立体 柱状支架， 由 LED模块化光源 11组合成的条状光源体位于固定支架 46的侧面圆 周上， LED模块化光源 11之间的组合连接可以采用实施例 8的连接方式， 使相邻 ^ LED模块化光源 11之间具有散热间隙 41，而且每个条状光源体之间也具有散热间 隙 41， 增强了大功率 LED灯的散热效果。
实施例 13
如图 18所示， 固定支架 46为菱形立体支架， LED模块化光源 11位于固定支 架 46的侧面圆周上， 由 LED模块化光源 11组合成条状光源体， LED模块化光源 11上固定杆 17的两端分别连接在固定支架 46的顶部与底部，从而将 LED模块化 光源 11固定在固定支架 46上， 每个条状光源体之间具有散热间隙 41， 固定支架 46内部中空, LED模块化光源 11上说的散热片 48均向固定支架 46的中心部位伸出， 对 LED灯散发的热量进行集中散热;而电源线 49从固定支架 46顶面引出，自 LED 模块化光源 11的布线通孔 16进入为每个条书状光源体供电。
实施例 14
如图 19所示， 固定支架 46为花形支架， LED模块化光源 11组合连接成条状 光源体， 各条状光源体呈中心发散状分布在固定支架 46上， 各条状光源体之间具 有散热间隙。
实施例 15
如图 20所示， 固定支架 46为柱体支架， 固定支架 46内部中空， LED模块化 光源 11组合连接成条状光源体分布在固定支架 46的侧面圆周上， LED模块化光 源 11上的散热片 48均向固定支架 46的中心部位伸出， 电源线从固定支架 46顶 面引出为每个条状光源体供电。
实施例 16
如图 21所示， LED模块化光源 11通过固定杆 16固定在固定支架 46上， 在 固定支架 46的底部安装有电源模块 50， 在固定支架 46的顶部安装有太阳能电池 板 51， 太阳能电池板 51接收太阳光并将太阳能传输到电源模块 43中贮存， 实现 节能环保； 在本实施例中， 太阳能电池板的结构 51 呈伞状， 遮挡住固定支架 46 的顶部， 可防止 LED灯受雨水和风力破坏。
实施例 17
如图 22所示， 为了增强 LED模块化光源 11之间连接的稳固性，在 LED模块 化光源 11的固定杆 16上连接加固支架 52, LED模块化光源 11通过固定杆 16连 接在固定支架 46上而固定在灯架 56上。
在其它的实施方式中， 也可以省去固定杆与固定杆通孔的结构， 而仅用组合 杆与组合杆通孔实现与固定支架的连接， 具体做法是组合杆的两端与固定支架相 连接， 但是， 与固定杆将组合后 LED模块化光源的固定在固定支架上的实施方式 相比较， 此连接结构的缺陷在于在调整 LED模块化光源的安装角度而转动组合杆 时， 可能会引起布线通孔内布线的损伤， 也同时影响 LED模块化光源之间连接的 稳固性。
本发明的实施方式不限于此， 根据本发明的上述内容， 按照本领域的普通技 术知识和惯用手段， 在不脱离本发明上述基本技术思想前提下， 本发明组合连接 架、 光源安装座的结构具有多种实施方式， 且 LED模块化光源上用于模块连接的 连接结构和布线结构也都可以根据说实际应用情况进行变换； 本发明 LED模块化光 源所组合成的大功率 LED灯的样式可随着固定支架的形状灵活改变，而 LED模块 化光源在固定支架上的固定方式也可以灵活书变化。 因此， 本发明还可以做出其它 多种形式的修改、 替换或变更， 均落在本发明权利保护范围之内。
