与现有技术相比， 本发明具有以下优点：
1 )、 具有良好散热效果。
首先， 将原本整块的散热器打散成各个模组， 模组间设有间隙。 把原本只 起到支撑作用的壳体式散热灯架也巧妙利用起来， 模组产生的热量传导给原本 只是起到结构件作用的壳体式散热灯架， 使其协助模组散热器散热， 把壳体式 散热灯架的表面积充分利用起来， 且在壳体式散热灯架的头部和尾部设置大量 的散热孔， 在灯盖上设置有通风口， 壳体式散热灯架上的大量的散热孔和灯盖 上的通风口之间形成空气对流， 产生热蜂窝效应， 利用热蜂窝效应使空气对流 起来， 充分穿越模组间的间隙及壳体式散热灯架的散热孔， 迅速带走热量。 再 配合灯盖的通风孔和灯盖壳体式散热灯架间的空隙， 空气对流通畅， 可以有效 的排出灯壳内部产生的热量， 具有极强的散热效果。 即， 所述壳体式散热灯架 设置有散热孔， 灯盖上设置有通风孔， 再加上 LED模组间的间隙、 灯盖与壳体 式散热灯架间的间隙形成空气通道， 整个灯具空气对流通畅， 对流散热效果明 显， 可以有效的排出灯壳内部产生的热量。
与现有的只采用模组间间隙来形成热蜂窝效应的技术相比， 所述模组化 LED照明装置的散热孔和模组间间隙相互加强作用， 可加强空气对流， 使得热 量更容易从灯壳内排出， 整灯可达到更好的散热效果。
其次， LED模组的热量通过散热器进行传导散热， 此外可通过散热器上的 凹槽结构和壳体式散热灯架的凸起梁将热量传导到壳体式散热灯架， 加强散热 效果。
2 )、 组件少、 易组装、 易维护、 成本低。
整灯组件数量少， 由压铸成型的壳体式散热灯架和灯盖组成， 壳体式散热 灯架与灯盖采用连接件铰接的方式连接， 灯盖开合方便， 压铸件上设计有安装 固定结构 , LED模组通过卡槽结构配合安装到灯壳内 ,然后通过手拧螺丝将 LED 模组固定。 灯盖和壳体式散热灯架间也是通过手拧螺丝固定。 所以在组装养护 时不存在拧螺丝的繁瑣工序， 无需工具即可实现拆装替换 LED模组。
3 )、 整灯具有良好的密封效果。
将整灯大面积整体密封分解为多个小型的 LED模组， LED模组之间通过防 水线连接， 从而提高 LED模组的密封性能即可达到整灯的密封性能， 而且相比 整灯， LED模组由于密封边圈周长短， 更易于达到密封效果。
LED模组的散热器和透镜组的贴合处， 设置有固体硅胶圈， 并且在固体硅 胶圈侧边涂有液体硅胶，到达双层防护作用。在 LED模组背面防水线出线孔处， 采用锲形硅胶圈和金属螺母紧固。 从而实现 LED模组的高防护等级， 达到整灯 的密封效果。
4 )、 驱动电源外置， 可提高整灯的安全性， 也便于驱动电源工作时所产生 热量的扩散， 以保证驱动电源正常工作， 且便于更换电源。
5 )、 壳体式散热灯架和灯盖上分别设置的支撑件进行齿合固定， 避免了支 撑件间的来回滑动， 且所述支撑件的设置形成了壳体式散热灯架和灯盖间的间 隙。

应用例一
实施例一
请参阅图 1至图 7, —种 LED照明装置， 包括灯盖 11、 壳体式散热灯架 12 组成的整灯灯壳 1 , 至少一 LED模组 2。 LED模组 2可以通过卡槽结构 30与壳 体式散热灯架 12上的凸起梁 23配合安装，然后通过手拧螺丝 29将 LED模组 2 锁紧固定， 可以形成整体 LED照明装置。 以下具体介绍本发明。
所述灯具中， 将原本整块的散热器打散成各个模组， 且在壳体式散热灯架 12的头部 44和尾部 46设置了大量的散热孔 24, 以散热孔和模组 2间间隙作为 热气流通道， 利用热蜂窝效应， 迅速带走热量。 散热孔 24和模组 2间间隙的相 互加强作用， 可加强空气对流。 根据不同的散热需求， 灯盖 11和壳体式散热灯 架 12之间可闭合或留有间隙， 所述散热壳体式散热灯架上的散热孔装置和灯盖 壳体式散热灯架间的间隙， 也可形成空气对流顺畅的散热通道。
所述壳体式散热灯架可使用高强度材料压铸而成。 壳体式散热灯架的头部 44和尾部 46沿凸起梁方向往两端扩展设有多排散热孔 24, 且设置了大量加强 筋 42。 加强筋 42不密集处的散热孔 24周边设置了散热孔烟囱壁 41 , 还有部分 加强筋 42可直接延续形成散热孔烟囱壁 41 , 如散热孔 14的散热烟囱壁 41。 散 热孔烟囱壁 41的设置使得热气流更容易从散热孔穿过， 形成热蜂窝效应。 其中 散热孔烟囱壁 41和加强筋 42都起到散热的作用，可增加整灯的散热面积。 LED 模组 2与模组间设置有间隙， 模组间间隙和散热孔相互作用， 可以加强空气对 流， 有效的排出灯壳内部产生的热量。
所述壳体式散热灯架 12可使用高强度材料压铸而成。在壳体式散热灯架 12 的尾部设有连接结构， 该连接结构与壳体式散热灯架 12可以一起压铸而成， 也 可以分开设置， 并固定。 壳体式散热灯架 12可以在连接结构上设置螺纹孔配合 压板 13 , 将整灯与灯杆连接起来。
所述壳体式散热灯架 12内部可以设置凸起梁 23。 凸起梁 23的个数可以是 一根， 也可以是多根， 凸起梁 23设置的方向和 LED模组 2的排列方向相一致， 以便固定。 凸起梁 23的形状是长条形， 以便其端部可以固定在壳体式散热灯架 12的两侧边上。 凸起梁 23的横截面也可以是多种形状， 比如椭圆形或方形等。 凸起梁的横截面 23与 LED模组 2上由铝型材成型出的卡槽结构 30配合， 特别 是凸起梁 23可卡入或可移出地连接于凹槽结构 30, 并且位于卡入状态下， 凸起 梁 23与凹槽结构 30紧密贴合， 壳体式散热灯架 12与凸起梁 23由金属材质或 包括石墨在内的散热材料制成。 这样， 当位于卡入状态下， LED模组 2上的热 量可以通过凸起梁 23经过壳体式散热灯架 12直接进行散热。
壳体式散热灯架 12—周设有若干支撑件 16, 灯盖 11一周上对应位置设置 配合件 17, LED照明装置处于闭合状态下， 支撑件 16与对应配合件 17适配固 定。 这种设置， 使得 LED照明装置的整体壳体固定， 不容易变形及错位。 在本 实例中， 配合件为椭圆形凹槽 18, 支撑件为椭圆柱， LED照明装置处于闭合状 态下， 所述椭圆形凹槽 18与椭圆柱进行齿合固定。 通过支撑件 16与对应配合 件 17的相互配合使灯盖在闭合状态时位置固定， 不发生错位和晃动。
另外， 灯盖 11和壳体式散热灯架 12通过连接件的铰接实现灯盖的开合。 本实施例中采用合页 15连接， 使开合非常方便。 通过改变合页 15长度， 可调 节灯盖侧面翻开的角度。
此外， 灯盖 11处于闭合状态时， 与壳体式散热灯架 12之间留有间隙， 使 空气流通顺畅， 使其散热性能更加出色。 LED模组 2间、 灯盖 11与壳体式散热 灯架 12间设置有间隙形成空气通道，可以有效的排出灯壳内部产生的热量。即， 壳体式散热灯架 12头部和尾部设置有多个散热孔 25, 可增强对流散热效果。 灯 盖 11上设置有通风孔 19, 可增强对流散热效果。 此外通过改变通风孔形状及排 布， 可起到美化灯具的作用。
LED模组 2上由铝型材成型出的卡槽结构 30配合， 此外壳体式散热灯架 12上的螺孔 24与 LED模组 2上的定位缺口配合， 以确定 LED模组 2的相对位 置，并通过手拧螺丝 29将 LED模组 2锁紧固定。手拧螺丝 29使 LED模组拆装 方便， 易于维护。
所述灯盖 11 可由塑料注塑成型或者铝压铸而成， 其一侧通过两个合页 15 与壳体式散热灯架 12连接， LED模组 2和灯杆安装完毕后， 合上灯盖 11 , 通过 手拧螺丝 14锁紧灯盖 11与壳体式散热灯架 12。 整灯组件数量少， 灯盖 11一侧 和壳体式散热灯架 12通过两个合页 15连接， 再将模组 2通过手拧螺丝 14固定 在壳体式散热灯架凸起梁上， 将灯杆通过压板固定在壳体式散热灯架尾部。 合 回灯盖， 拧上手拧螺丝即可， 安装便捷， 安装效率高。 且可进行徒手维修， 只 需拧掉手拧螺丝更换模组即可。
LED模组 2—般包括散热器 28、 PCB板 27、 透镜组 26。 散热器 28可由铝 合金型材截成， 散热器 28上成型出相应的凹槽结构 30配合安装到壳体式散热 灯架 12上的凸起梁 23上， 并利用手拧螺丝 29通过壳体式散热灯架 12上的螺 孔 24与散热器 28上加工出的缺口完成 LED模组 2的水平定位。 散热器 28和 透镜组 26的贴合处，设置有固体硅胶圈，并且在固体硅胶圈侧边涂有液体硅胶， 到达双层防护作用。 在 LED模组 2背面防水线出线孔处， 采用锲形硅胶圈和金 属螺母紧固。 从而实现 LED模组的高防护等级， 达到整灯的密封效果。
LED模组 2间通过防水线连接。 驱动电源外置， 电线穿过灯杆导出， 可提 高投光灯的安全性， 也便于驱动电源工作时所产生热量的扩散， 以保证驱动电 源正常工作， 且便于更换电源。
