技术领域
本发明涉及一种线性LED光源,特别涉及一种线性LED光源的封装结构。
背景技术
市面上常见的线性LED光源中,多个LED芯片设置在基板上并用金线将多个LED芯片和连接端子键合,并涂覆荧光胶使荧光胶包覆在基板和LED芯片上,再将两端的连接端子分别接入电源的两端。采用此种封装结构的线性LED光源中,采用金线键合LED芯片,质量风险高;基板和包覆LED芯片的荧光胶导热性均较差,导致LED芯片产生的热量无法散去;同时,难以保证荧光胶均匀地涂覆在基板和LED芯片上,降低了线性LED光源的光色均一性。

进一步的,所述导电镀层完全覆盖倒装LED芯片的正负极。
进一步的,所述导电镀层的宽度与荧光胶封层的宽度相等。
本发明所述一种线性LED光源的封装结构的封装步骤为:

B、采用芯片级封装技术在步骤A所获得的产品上覆盖荧光胶,并将荧光胶烘干;
C、使用真空镀膜设备在连接端子和倒装LED芯片的电极镀上导电镀层,使相邻倒装LED芯片的相邻电极电连接,连接端子与其相邻的倒装LED芯片电连接;
D、使用划片机以列或行为单位切割C中获得的产品即为本发明所述线性LED光源。
本发明所述一种线性LED光源的封装结构中采用倒装LED芯片,通过导电镀层电连接相邻倒装LED芯片的相邻电极和连接端子,再用荧光胶包覆发光组件和连接端子,
本发明所述一种线性LED光源的封装结构有如下优点:
(1)省去了基板,提高了本发明所述线性LED光源的可塑性,可随意弯曲,可用于制成不同形状的线性LED光源;
(2)导电镀层覆盖在倒装LED芯片的电极上,增大了倒装LED芯片的散热面积;
(3)倒装芯片LED之间通过导电镀层电连接,取代了金线键合LED芯片的电连接方式,且省去了基板,减少了生产成本;
(4)采用倒装LED芯片,线性LED光源的稳定性更强;

参照图1-2,提出本发明的的一实施例,所述线性LED光源的封装结构包括发光组件1、导电镀层2、连接端子3和荧光胶封层4。
所述发光组件1由多个倒装LED芯片11沿直线排列而成,且相邻的倒装LED芯片11相邻的电极相反,相邻的倒装LED芯片11相邻电极通过导电镀层2电连接,即倒装LED芯片11的正极111与其相邻的倒装LED芯片11的负极112通过导电镀层2电连接。
发光组件1的两端分别设有一连接端子3,连接端子3与其相邻的倒装LED芯片11的相邻电极通过导电镀层2电连接,发光组件1的两端的连接端子3用于接入电源的两端。
荧光胶封层4涂覆在发光组件1和连接端子3上,使发光组件1和连接端子3固定在荧光胶封层4上,省去基板,节约了线性LED光源的生产物料,降低了成本;提高了本发明所述线性LED光源的可塑性,可随意弯曲。
导电镀层2涂覆在相邻倒装LED芯片11相邻的电极上,导电镀层2实现了发光组件1和连接端子3之间的电连接,连接端子3与其相邻的倒装LED芯片的相邻电极通过导电镀层2电连接,避免使用金线键合发光组件1和连接端子3,提高了线性LED光源质量的稳定性。
导电镀层2完全覆盖倒装LED芯片11的两极,导电镀层2增加了倒装LED芯片11的散热面积,有利于增加倒装LED芯片11的寿命;当导电镀层2的宽度与荧光胶封层4的宽度相同时,导电镀层2可用于反射倒装LED芯片11向下发出的光,有利于增加线性LED光源的光强。
