Abstract

本发明公开了一种钓鱼灯专用紫光LED及其制造方法，包括一陶瓷基板，所述陶瓷基板中心布置有两颗紫光芯片，两所述紫光芯片通过键合金丝并联形成回路，两所述紫光芯片采用峰值波长均在410～420nm的45*45mil大功率垂直芯片，所述陶瓷基板的金锡合金镀层上封装有一向外凸起呈半球形的外胶。由于本发明从遴选紫光LED芯片的结构、波长到封装工艺恰好能满足钓鱼灯使用的苛刻要求，野钓实践中，10‑30m距离，紫光投射到浮漂上与浮漂上荧光涂层产生荧光反应，在整体黑暗的环境中，浮漂特别醒目，紫光LED在空气中传播，衰减很快，基本没有余光反射回来，不会使钓鱼者产生视觉疲劳，紫光LED还能发出一种特定的声呐，能吸引鱼儿。

Description

一种钓鱼灯专用紫光LED及其制造方法
技术领域
本发明涉及LED光源技术领域，更具体地说是一种钓鱼灯专用紫光LED及其制造方法。
背景技术
钓鱼已经发展成为一种大众广泛参与的娱乐休闲项目，越来越多的钓鱼爱好者喜欢夜间垂钓，特别是在夏季。夜间垂钓使用的LED钓鱼灯普遍采用大功率白光LED、蓝光LED或者暖白光LED作为光源。
在夜间垂钓实践中，使用白色LED光源照射浮漂，在照亮浮漂的同时把浮漂周围的水面也一同照亮了，浮漂目数的变化会因整个区域偏亮而较难判断，同时水面反射回来的光线也极易使钓鱼者眼睛产生疲劳，强光还容易将聚拢的鱼儿赶走。此外，蓝光LED还是暖白光LED尽管使用广泛，但或多或少也存在上述问题。
发明内容
本发明的目的在于克服现有技术以上缺陷，提供一种正向出光直线照射距离较远，散热性能优异，既能保证可见光的亮度，又能维持一定的紫外光功率的钓鱼灯专用紫光LED及其制造方法。
为了达到以上目的，本发明是通过以下技术方案实现的：一种钓鱼灯专用紫光LED，包括一陶瓷基板，其特征在于，所述陶瓷基板中心布置有一层金锡合金镀层，所述金锡合金镀层上布置有两颗紫光芯片，两所述紫光芯片底部上也各布置有一层金锡合金镀层，两所述紫光芯片底部上的金锡合金镀层分别与所述陶瓷基板中心上的金锡合金镀层相键合，两所述紫光芯片通过键合金丝并联形成回路，两所述紫光芯片采用峰值波长均在410～420nm的45*45mil大功率垂直芯片，所述陶瓷基板的金锡合金镀层上封装有一向外凸起呈半球形的外胶。
作为优选，所述陶瓷基板的化学成份按质量百分数计为：氮化铝90-93％、碳酸钙2-5％、氧化硅1-3％、高岭土1-3％。
一种钓鱼灯专用紫光LED的制造方法，其特征在于，包括以下步骤：
(1)将两颗紫光芯片以及陶瓷基板共同置于固晶机上进行固晶作业，通过共晶工艺将两紫光芯片底部上的金锡合金镀层分别与陶瓷基板中心上的金锡合金镀层相键合；
(2)将固定好两颗紫光芯片的陶瓷基板置于焊线机上进行焊线作业，将两颗紫光芯片通过键合金丝并联形成回路；
(3)将焊好两颗紫光芯片的陶瓷基板置于模压机中进行模压作业，用成份为硅胶的外胶在陶瓷基板的金锡合金镀层上封装形成一向外凸起的半球形凸顶透镜。
有益效果：由于本发明从遴选紫光LED芯片的结构、波长到封装工艺恰好能满足钓鱼灯使用的苛刻要求，野钓实践中，10-30m距离，紫光投射到浮漂上与浮漂上荧光涂层产生荧光反应，在整体黑暗的环境中，浮漂特别醒目，紫光LED在空气中传播，衰减很快，基本没有余光反射回来，不会使钓鱼者产生视觉疲劳，紫光LED还能发出一种特定的声呐，能吸引鱼儿，给钓鱼者提供了不少便利以及趣味。
