[0005] 现有技术中的 LED模组的散热一般是通过增大散热器的体积尺寸或增加电风扇
, 这些方法使散热器体积笨重、 结构复杂且会增加制造成本。 并且， 现有技术 中的大功率模组式 LED灯具， 功率一般在 500W左右， 不能替换更高功率的传统 灯具， 使得 LED灯具的应用受到限制； 并且 LED灯具的体积和风阻也较大， 不 仅不方便 LED灯具的安装， 而且会影响 LED灯具的安全使用， 造成安全隐患。

[0031] 从上述描述可知， 本发明的有益效果在于： 底板上的热量传递给主散热翅片 和辅助散热翅片， 由于主散热翅片的厚度较厚， 可以吸收更多的热量， 因此， 通过热传导， 可以将底板上的大部分热量带走； 辅助散热翅片设置在分隔区域 上， 辅助散热翅片为分段结构， 可以增加辅助散热翅片与空气的接触面积， 从 而增大辅助散热翅片与空气的对流， 通过热传导和热对流相配合的散热方式， 不仅可改善模组的散热效果， 而且无需将散热器做的较大且辅助散热翅片的厚 度较薄， 从而使得散热器具有体积小、 重量轻的优点。
[0032] 进一步地， 所述主散热翅片 21呈米字形排列在底板 1上， 所述辅助散热翅片 22 包括第一辅助散热翅片 221和第二辅助散热翅片 222, 所述第一辅助散热翅片 221 的排列方式为圆形排列， 所述第二辅助散热翅片 222平行主散热翅片 21设置。
