超小超薄高光效侧射型高亮白光LED元件
技术领域
本发明涉及一种超小超薄高光效侧射型高亮白光LED元件,尤其涉及一种小型侧发光型LED元件。
背景技术
目前现行市面上的小型侧发光型LED指示灯有两大类:
(1)支架类:主要以PPA树脂+铜支架为基板,主要尺寸有020(3.8*1.05*0.6mm)、010(3.8*1.0*0.4mm)、215(2.8*1.0*0.9mm)、335(3.8*0.6*1.2mm),其尺寸相对较大,而且支架类侧射型LED主要集中在020、010两款型号上,但是厚度最薄也要0.4mm。
(2)PCB类:主要是以BT树脂为基板,主要尺寸有0603(1.6*1.1*0.6mm)、0805(2.0*1.1*0.6mm)、1204(3.0*1.5*1.0mm),PCB类侧射型白光因传统工艺尺寸较大且PCB热阻过高,高亮白光目前无法解决散热问题。
发明内容
本发明的目的是克服现有技术存在的缺陷,提供一种厚度极薄、且散热效果好的超小超薄高光效侧射型高亮白光LED元件。

所述导电体为铜柱或导电胶。
所述基板的下底面上覆盖有第一金属导电层,该金属导电层分为相互不连接的正极区域和负极区域,所述负极区域连续覆盖在与负极导线连接的导电体下方,并与该导电体接触,所述正极区域连续覆盖在其他导电体下方,并与其他导电体接触。

(三)产品极小化极薄化的设计,通过PCB线路设计将正负极分布在PCB基板的底部,使LED产品厚度控制在0.3mm±0.1mm。
(四)本侧射型机种在客户端使用时,朝左或朝右发光时不需重新换机种,可以直接将产品在包装时换向,产品焊盘设计上能达到共用性。
