说明书 照明设备的散热装置
#細或
[1] 本发明是关于一种照明设备， 特别是指一种照明设备的散热装置。
[2] 目前所使用的户内外照明灯具等设备， 包括路灯等， 为求高亮度照明， 需消耗 大功率， 以致产生高热， 需要相当的散热面积将热量散出。 单纯依靠光源基座 上对光源的敞开面积及配合基座本身的金属材质实现散热的形式已无法满足高 亮度照明灯具的散热要求， 而限制了高亮度照明灯具的使用寿命。 因此便出现 了在该散热基座的四周成型有复数个散热鰭片而提高散热效果的结构， 散热片 的数量与基座的散热效果成正比， 即散热鰭片的数量愈多则散热表面积愈大， 散热效果愈佳。 但是目前照明设备的基座上的各散热鰭片是直接成型在基座外 周， 受散热鰭片在成型吋的厚度要求， 令散热鰭片的成型数量有限， 至无法进 一步提高基座的散热效果。
[3] 本发明的目的是提供一种可以提高基座周缘散热鰭片数量， 以提高基座散热效 果的照明设备的散热装置。
[4] 为实现上述目的， 本发明的解决方案是：
[5] 一种照明设备的散热装置， 其包括一散热承接座、 设置于散热承接座中的光源 模块及连接光源模块与散热承接座的导热装置； 其中： 该散热承接座是由两纵 向基架与两横向基架构成的矩形基座， 各基架的外周缘配合有复数个散热鰭片
[6] 所述各基架的外表面的上下延伸有凸边以形成为嵌置散热鰭片的 U型嵌槽。
[7] 所述嵌槽中与凸边平行的设有一凸垣。
[8] 所述各基架的内表面上凸设有复数个限位导热装置的凸筋。
[9] 所述各个散热鰭片是独立设置的片体， 其片身上分布有复数个增加散热面积的 通孔， 其下部的宽度小于等于嵌槽的宽度； 其上部的宽度小于等于基架的高度 [10] 所述各散热鰭片的上端设有横向凸出的两凸耳， 凸耳的前端形成缩颈， 对应该 缩颈的宽度在凸耳的后端形成配合缺口。
[11] 所述各散热鰭片的下端缘与凸耳同向延伸有凸脚。
[12] 所述各散热鰭片的下端缘设有一纵向缺槽。
[13] 所述光源模块包括承接板及光源， 在承接板上表面呈横向与纵向分别设有嵌置 导热装置的嵌槽， 光源是覆盖于承接板的上表面上， 以将导热装置的一部份夹 设于承接板与光源之间。
[14] 所述导热装置对应嵌槽的形状， 设置有复数个横向 U型片体， 及复数个纵向 L 型片体。
[15] 釆用上述方案后， 由于本发明照明设备中横向与纵向分布的导热装置可将光源 模块上光源产生的热能均匀迅速的传导至散热承接座上， 而散热承接座上的复 数散热鰭片是为独立设置的片体， 各散热鰭片片体厚度不受与承接座一次成型 的限制， 其厚度可以设置得足够薄， 可以增加承接座周缘散热鰭片的排布数量 ， 有效提高散热承接基座的散热面积， 及吋的将热能发射于空气中， 以此保证 照明设备中光源热能的散热要求， 可保障高亮度照明设备的使用寿命。

[25] 导热装置 3对应上述嵌槽 211的形状， 设置有复数个横向 U型片体 31， 及复数个 纵向 L型片体 32。
[26] 配合图 4、 5所示， 本发明的关键在于： 该散热承接座 1是由两纵向基架 11与两 横向基架 12构成的矩形基座， 各横向基架 11与纵向基架 12的外周缘配合有复数 个散热鰭片 13。
[27] 其中该横向基架 11与纵向基架 12的外表面的上下延伸有凸边 111、 121以形成为 U型嵌槽 112、 122, 而该嵌槽中与凸边 111、 121平行的设有一凸垣 113、 123； 另 该横向基架 11与纵向基架 12的内表面上凸设有复数个限位导热装置 3的 U型片体 3 1、 L型片体 32的凸筋 114、 124。
[28] 复数个散热鰭片 13是独立设置的片体， 各散热鰭片 13片身上分布有复数个通孔 131， 以增加散热面积， 其下部的宽度小于等于嵌槽 112、 122的宽度； 其上部的 宽度小于等于横向基架 11与纵向基架 12的高度； 另各散热鰭片 13的上端设有横 向凸出的两凸耳 132， 凸耳 132的前端形成缩颈 1321， 对应该缩颈 1321的宽度在 凸耳 132的后端形成配合缺口 1322; 在散热鰭片 13的下端缘与上述凸耳同向延伸 有凸脚 133， 另在该下端缘设有一纵向缺槽 134以与上述凸垣 113、 123配合。
[29] 配合图 6、 7所示， 各散热鰭片 13呈凸耳 132为相同方向的排列， 相邻的两散热 鰭片 13利用后部的散热鰭片 13凸耳 132的缩颈 1321卡制于前部散热鰭片 13凸耳 13 2的配合缺口 1322中， 如此依次将复数个散热鰭片 13连接在一起， 此处各凸耳 13 2的设置， 一是方便各散热鰭片 13之间的连接定位， 二是方便各散热鰭片 13之间 更方便的均匀排列； 而凸脚 133的设置是增加散热鰭片 13与基架的接触面积， 提 高散热效果。
[30] 再如图 4、 5所示， 各连接好的复数个散热鰭片 13利用其缺槽 134滑嵌于向横向 基架 11与纵向基架 12的 U型嵌槽 112、 122中焊固， 再将两横向基架 11与两纵向基 架 12的相邻边进行焊接即可构成一矩形散热承接座 1。
[31] 如图 2、 3所示， 组合吋， 各导热装置 3的 U型片体 31、 L型片体 32是分别嵌置于 承接板 21的嵌槽 211中后， 再将光源 22覆盖于承接板 21的上表面上， 由承接螺纹 4锁固， 而凸伸出的各 U型片体 31、 L型片体 32的伸脚 311、 321插置横向基架 11与 纵向基架 12的内表面上的凸筋 114、 124形成的限位槽中， 通过各固定片 5由螺钉 6锁固于基架上， 如此便形成一具有散热装置的照明装置。
[32] 该横向与纵向分布的导热装置 3可将光源模块 2上光源 22产生的热能均匀迅速的 传导至散热承接座 1上， 而散热承接座 1上的复数散热鰭片 13是为独立设置的片 体， 则各散热鰭片 13片体厚度不受与承接座一次成型的限制， 其厚度可以设置 得足够薄， 如此， 可以增加承接座 1周缘散热鰭片 13的排布数量， 有效提高散热 承接基座 1的散热面积， 及吋的将热能发射于空气中， 以此保证照明设备中光源 热能的散热要求， 可保障高亮度照明设备的使用寿命。
