Description

一种高功率的发光二极管封装方法
技术领域
本发明涉及一种发光二极管封装方法。
背景技术
目前传统发光二极管(LED)封装,是以单一LED晶粒置于金属支架上后再灌环氧树脂(Epoxy)封装(参阅图1),传统LED封装因散热效率低,LED晶粒无法承受高温,容易产生劣化现象,导致LED亮度降低,亦缩短LED寿命。
近年来发光二极管(LED)正逐渐被运用于照明上,特别是在光线波长在360-410nm(近UV光)间的LED晶粒,利用短波长激发荧光体产生白光或各色光,提供照明、艺术或其它地方使用,现已经有大量商品开始出售。但过去发光二极管都是置于金属支架碗杯中再灌胶封装,由于支架碗杯体积小无法有效散热,以致在大电流时LED容易劣化并使寿命变差,到目前为止很难找到可通大电流,且散热佳的LED封装方式。
常用的LED照明灯具号志灯及LED照明灯泡是将数个灯型LED(Lamp type)元件安置在电路板上,由于使用数个LED组成,会造成灯具体积增加,另若使用多LED晶粒组合取代,则将发生LED灯具无法有效散热,发光效益降低。
白光LED具有环保、安全、寿命长、节能等多项特点,白光LED将会是一场“白光照明革命”,使用白光LED晶粒于本发明的高功率的发光二极管封装方法,更能提高白光LED的有光强度的效果。
发明内容
本发明的主要目的是提供一种高功率的发光二极管封装方法,可以提高温度的散热,而增加寿命,亦可提高工作电流达到提升LED亮度。
为实现上述目的,本发明提供的一种高功率的发光二极管封装方法,由发光二极管晶粒、环氧树脂、电路板、金属块和电极圆柱共同封装组成;其中将具有孔洞的电路板过锡炉,如此表面孔洞灌满焊锡后经热压形成凹杯或经机械加工方式形成凹杯;取发光二极管晶粒黏置于凹杯中,并经金属块以导电胶黏置或焊锡焊接电路板所有凹杯下方,固定电极圆柱置于电路板两侧上,再将发光二极管晶粒两电极分别和电极圆柱及电路板以传导线连接,最后再以环氧树脂封装成灯型结构。
其中电路板上的凹杯为复数个,每一凹杯可放置一颗或多颗发光二极管晶粒。
其中电路板为一印刷电路板(P.C.B)或陶瓷电路板,该电路板的表面印刷铜箔电路板并钻孔,电路板面可直接布局配置电路和放置电子零件,制作电路的串并联及升降压和闪烁使用。
将已封装完成的灯型发光二极管结构直接放入一导电金属的空心圆管中,空心圆管前端内缩与灯型发光二极体的帽缘接合,并放入电池于空心圆管中使电池正极与金属块接触,负极则由金属管壁导电连通接触到发光二极管的侧面电极圆柱,形成一照明器具。
本发明提供的一种高功率的发光二极管封装方法,由发光二极管晶粒、环氧树脂、金属块和电极圆柱或电极圆管共同封装组成;其中取发光二极管晶粒黏置于金属块上的凹杯中,以绝缘胶固定电极圆柱或电极圆管于金属块上,再将发光二极管晶粒两电极分别和金属块及电极圆柱或电极圆管以传导线连接,最后再以环氧树脂封装成灯型结构。
其中金属块为一高导电及高导热的金属块,如铜块,为发光二极管的电极,且外型结构为一与灯丝型灯泡相同具有螺纹铜头外观。
其中电极圆管为一高导电及高导热的金属圆管,如铜管,为发光二极管的电极,且外型结构为一与灯丝型灯泡相同具有螺纹铜头外观。
