Description

一种背光模组用 LED灯条及背光模组
【技术领域】
本发明属于液晶显示领域， 更具体的说， 涉及一种背光模组用 LED灯条及 背光模组。
【背景技术】
LED光源发光效率高， 节能环保， 而且寿命长， 作为背光源广泛应用于液 晶显示装置中， 由于 LED发热量大， 故 LED灯条需要专门的散热基座， 为了保 证 LED灯条与散热基座之间的导热性能，一般会在 LED灯条的背部设置导热胶， 然后再把 LED灯条和导热胶一块粘贴到散热基座上，传统的 LED灯条为长条状 的平板结构， LED灯条正面设置有 LED灯， LED灯条的背部是一个平面， 在粘 贴导热胶时，导热胶既薄又窄且软，长度也很长，很难整齐且严密地贴附于 LED 灯条的背部平面， 如图 1所示， 导热胶 2贴附不齐会影响 LED灯条 1散热的均 匀性， 如图 2所示， 导热胶 2与 LED灯条 1背部贴合不严密， 产生气泡更会阻 碍热量的传导。
为了粘贴好导热胶， 人们常采用的方法是将导热胶拉扯以达到绷直， 然后 再粘贴到 LED灯条的背面， 这会使导热胶存在内拉应力， 当背光模组被点亮升 温、 久置、 或者受潮等情况下， 导热胶粘贴时产生的内拉应力会使得导热胶急 剧发生回缩， 从而造成脱胶、 变形， 影响 LED灯条的散热效果和稳定性。
【发明内容】
本发明所要解决的技术问题是提供一种背光模组用 LED灯条及背光模组， 所述 LED灯条在粘贴导热胶时更整齐严密， 而且粘贴效率更高。
本发明的技术方案为：一种背光模组用 LED灯条，所述 LED灯条正面设置 有 LED灯， LED灯条背面为一平面， 用于粘贴导热胶， 所述 LED灯条背面设 有用于定位导热胶的定位边， 所述定位边凸出于 LED灯条背部平面， 所述定位 边位于 LED灯条背面的上缘和下缘， 所述定位边为分段式结构， 由多个小段组 成， 所述定位边每个小段形状为矩形或梯形。
本发明的另一种技术方案为：一种背光模组用 LED灯条，所述 LED灯条正 面设置有 LED灯， LED灯条背面为一平面， 用于粘贴导热胶， 所述 LED灯条 背面设有用于定位导热胶的定位边， 所述定位边凸出于 LED灯条背部平面。
优选的， 所述定位边位于 LED灯条背面的上缘， 在粘贴导热胶时， 操作人 员以上定位边为准对齐即可。
优选的， 所述定位边位于 LED灯条背面的下缘， 在粘贴导热胶时， 操作人 员以下定位边为准对齐即可。
优选的， 所述定位边位于 LED灯条背面的上缘和下缘。
优选的， 所述定位边为分段式结构， 由多个小段组成。 在把 LED灯条和导 热胶粘附到散热基座上时， 导热胶会产生压应力， 导热胶可以向相邻小段之间 的间距进行形变， 从而释放部分压应力。
优选的， 所述定位边每个小段形状为矩形或梯形。
优选的， 所述定位边形状为矩形方波， 同样能为导热胶提供变形空间， 释 放部分压应力。
优选的， 所述定位边形状为梯形波， 同样能为导热胶提供变形空间， 释放 部分压应力。
本发明的有益效果为： 本发明背光模组用 LED灯条背面设有用于定位导热 胶的定位边， 所述定位边凸出于 LED灯条背部平面， 定位边可以使操作人员在 贴附导热胶时通过靠齐定位边的边缘来进行整齐贴附， 导热胶粘贴的整齐， 与 LED灯条的配合自然就会更严密， 由于不需进行拉扯来绷直导热胶， 从而避免 了内拉应力的产生， 这样， 即使在恶劣的使用环境下， 也不容易发生脱胶和变 形， 保证了背光模组的稳定性和散热效果。
本发明还公开了另一种技术方案： 一种背光模组， 包括上面所述的 LED灯 条、 散热基座和导热胶， 所述导热胶一边与 LED灯条粘贴， 另一边与散热基座 粘贴， LED灯条上的定位边的高度小于导热胶的厚度。
优选的， 所述散热基座为铝质挤出型材。
本发明所述背光模组 LED灯条上的定位边的高度小于导热胶的厚度， 目的 是为了使定位边不影响导热胶与散热基座之间的粘贴。
