Description

一种LED拱形透镜成型方法 一种LED拱形透镜成型方法
技术领域
本发明涉及一种LED透镜成型方法,尤其是涉及一种LED拱形透镜成型方法。
背景技术
现有的LED透镜的制作一般是将荧光粉混合模顶胶注入方形或圆形的模具中,从而形成方形或圆形的LED透镜。按照此种方法制成的LED透镜颜色一致性不够好,且发光面小。
发明内容
为了克服现有技术的不足,本发明提出一种LED拱形透镜成型方法,可以制作出表面为拱形的LED透镜。本发明LED拱形透镜成型方法包括以下步骤:
S1 :准备LED透镜模具,所述模具用来注入荧光粉和模顶胶混合物的部分的底部为圆形,并向上圆弧状逐渐扩大,其最上端开口为圆形,且开口边缘具有向上的凸起;
S2 :向LED透镜模具中注入荧光粉和模顶胶混合物;
S3 :所述荧光粉和模顶胶混合物在表面张力的作用下成型为拱形凸起的LED透镜。
进一步地,根据步骤S1所述的模具,可以是注塑形成的LED灯杯。
进一步地,根据步骤S3所述的拱形凸起的LED透镜,可以是半球体形的LED透镜。
应用本发明所述的LED拱形透镜成型方法制作而成的LED拱形透镜或半球形透镜,其发光面更大,并且拱形或半球形的LED透镜发出的光线相互交叉,整体发出的光颜色一致性更好。
附图说明
为了更清楚地说明本发明的实施例,下面将对实施例描述中所需要使用的附图作简单地介绍,显而易见地,下面描述中的附图仅仅是本发明的一个实施例,对于本领域普通技术人员来讲,在不付出创造性劳动性的前提下,还可以根据这些附图获得其他的附图。
图1是本发明LED拱形透镜成型方法流程图;
图2是本发明LED拱形透镜成型方法流程图步骤S1中LED透镜模具的结构示意图。
具体实施方式
下面结合具体实施方式对本发明作进一步的说明。其中,附图仅用于示例性说明,表示的仅是示意图,而非实物图,不能理解为对本专利的限制;为了更好地说明本发明的实施例,附图某些部件会有省略、放大或缩小,并不代表实际产品的尺寸;对本领域技术人员来说,附图中某些公知结构及其说明可能省略是可以理解的。
请参见图1,本发明LED拱形透镜成型方法包括以下步骤:
S1 :准备LED透镜模具,从图2可以看到,所述模具用来注入荧光粉和模顶胶混合物的部分的底部1为圆形,并向上圆弧状逐渐扩大,其最上端开口为圆形,且开口边缘具有向上的凸起2;
S2 :向LED透镜模具中注入荧光粉和模顶胶混合物;
S3 :所述荧光粉和模顶胶混合物在表面张力的作用下成型拱形凸起的LED透镜。
根据步骤S1所述的模具,可以是注塑形成的LED灯杯,将荧光粉和模顶胶混合物注入LED灯杯后,能直接形成LED灯珠。
其中,根据步骤S3所述的拱形凸起的LED透镜,可以是半球体形的LED透镜。调整步骤S1中的模具底部和开口的大小及其开口处边缘的形状,可以使得在表面张力作用下的荧光粉和模顶胶混合物成型的LED透镜为半球形。
以上所述仅为本发明的较佳实施例而已,并不用以限制本发明,凡在本发明的精神和原则之内,所作的任何修改、等同替换、改进等,均应包含在本发明的保护范围之内。
