Description

LED白光制作工艺
技术领域
本发明涉及LED白光制作工艺，适用于LED封装技术领域。
背景技术
LED（发光二极管,light -EmittingDiodc）是一类可直接将电能转化为可见光和辐射能的发光器件，是未来光源的首选，具有工作电压低，耗电量小，发光效率高，发光响应短，光色纯，结构牢固，抗冲击，性能稳定，重量轻、体积小等优良特性。而传统LED封装总是偏色，其主要原因是荧光粉与胶水的混合比例不当。因此，人们希望有一种新的封装方法能够解决这个问题。
发明内容
为了解决LED封装偏色的问题，本发明提供了一种白光LED制作工艺。
本发明解决其技术问题的技术方案是由以下工艺方法构成：
（1）取适用的荧光粉与胶水；
（2）将荧光粉与胶水按0.55～0.65：1的重量比均匀混合；
（3）将步骤（2）所得物质涂覆在发光二极管晶片上；
（4）烘干、封装。
本发明具有工艺先进、涂覆效果好、出光不偏色等优点。
具体实施方式
示例：将本发明运用在1W大功率白光LED光源的制作上。
首先将6克yag荧光粉，10g白光胶水进行充分混合均匀，然后用点涂的方法覆在晶片表面上，接着，将涂覆后的晶片放进烘箱，在130℃的温度常压状态下烘烤1小时，取出封装。即制得不偏色的白光LED光源。
