技术领域
本发明涉及一种液晶显示技术领域, 尤其涉及一种背光散热结构和液晶模 组。 背景技术
液晶模组是由液晶面板, 机构框架、 光学部材等组成。 由于液晶本身不发 光, 需要配置一些背光源才能显示出画面。 现有技术中, 一般使用 CCFL ( Cold Cathode Fluorescent Lamp, 冷阴极萤光灯管)或 LED ( Light Emitting Diode, 发 光二极管)作为背光源, LED由于其轻小、 节能、 容易实现超薄和窄边框涉及, 逐渐成为主流的背光源。
对于侧入式 LED背光模组, 由于 LED发热量大, 当 LED温度升高, 其量 子效率将极大降低, 导致 LED亮度下降, 并且严重影响 LED的工作寿命, 因此 需要一系列散热措施以保证 LED背光源的正常工作。
现有技术是把 LED灯条固定在铝挤上散热, 但是这种散热方式的散热能力 还是不高, 无法很好的提高 LED的工作效率和寿命。 发明内容
为解决现有技术中存在的背光模组无法很好的散热所带来的 LED液晶模组 工作效率不高, 且寿命不长的技术问题, 本发明提供一种背光散热结构和相应 的液晶模组, 其能够提高 LED的工作效率和寿命。

其中, 所述 槽的数量至少为两个。
其中, 当所述背板为长侧入光背板时, 所述凹槽开设于靠近所述背板长侧 边的位置, 与所述背板的长侧边垂直; 所述铝挤装配于所述背板的长侧边。
其中, 当所述背板为短侧入光背板时, 所述凹槽开设于靠近所述背板短侧 边的位置, 与所述背板的短侧边斜交; 所述铝挤装配于所述背板的短侧边。
本发明还提供了一种液晶模组, 包括液晶面板、 机构框架、 光源以及如前 所述的背光散热结构; 所述光源设置在所述背光散热结构上, 所述液晶面板通 过所述结构框架与所述背光散热结构相互紧固配合。
实施本发明提供的背光散热结构和液晶模组, 由于该背光散热结构开设有 凹槽, 其根据热空气向上升的原理, 使热空气将热量带至整个背板、 并且引导 出外界环境, 从而提高背光模组的散热能力, 进而提高 LED液晶模组的工作效 率和寿命。

对流状况、 散热部件的辐射系数等; 当散热路径的热阻越低, 对流系数越高、 散热表面积越大、辐射系数越高,液晶模组散热能力越强,就越能及时散去 LED 的热量, 基于此, 本发明实施例提供一种背光散热结构和相应的液晶模组, 其 能够提高 LED的工作效率和寿命。
