Abstract

一种复合透镜，包括LED板(1)和透镜(2)，单个透镜(2)内凹若干个用于容置LED板(1)上LED(11)的抛物状容腔(21)。LED板(1)上设有定位槽(12)，透镜(2)的一端延伸出透镜(2)底面的凸柱(22)嵌入LED板(1)的定位槽(12)，将透镜(2)固设在LED板(1)上。

Description

复合透镜 技术领域
本发明涉及一种复合透镜。 
 背景技术
CN200910303872.4公开了一种发光二极管模组，它的目的是提供一种无明显眩光的发光二极管模组。该技术方案: 所述发光二极管模组，包括一发光二极管及一与发光二极管搭配的透镜，该发光二极管与该透镜具有一相同的光轴，该透镜具有一供发光二极管的光线入射的入光面及一供其出射的出光面，且该入光面内凹，该出光面外凸，使得从透镜射出的光线的峰值光强出现在偏离光轴52～67 度的范围内。本发明采用透镜直接对发光二极管的光线进行调节，将发光二极管光轴附近的光分散开来，从而有效避免眩光的产生。其不足之处是:这种方法只能是做定向光源,也就是说做聚光用的方法,不能将LED的光做扩散使用。
现有灯具使用透镜做LED的光扩散时，通常采用的方法是一颗LED使用一个透镜的方法，生产过程烦琐，成本也高。
 技术问题
本发明的目的是提供一种多颗LED使用一个透镜实现光扩散、调整光角度的复合透镜。本发明的另一目的是提供一种节省成本，节省灯具内部空间的复合透镜。
 技术解决方案
本发明的技术解决方案是所述复合透镜，包括LED板和透镜，其特殊之处在于，所述单个透镜内凹若干个用于容置LED板上的LED的容腔。
作为优选：所述LED板上设有定位槽，所述透镜的一端延伸出透镜底面的凸柱嵌入所述LED板的定位槽，将透镜固设在LED板上。
作为优选：所述容腔为抛物状凹腔。
 有益效果
生产方便，节省成本。
节省灯具内部空间。
 附图说明
图1是本发明复合透镜的结构示意图；
图2是图1的俯视结构示意图。
 本发明的最佳实施方式
本发明下面将结合附图作进一步详述：
请参阅图1、图2 所示，该复合透镜，包括LED板1和透镜2，所述单个透镜2内凹若干个用于容置LED板1上LED11的抛物状容腔21。所述LED板1上设有定位槽12，所述透镜2的一端延伸出透镜底面的凸柱22嵌入所述LED板1的定位槽12，将透镜2固设在LED板1上。
 工业实用性
以上所描述的仅为本发明的较佳实施例，上述具体实施例不是对本发明的限制。在本发明的技术思想范畴内，可以出现各种变形及修改，凡本领域的普通技术人员根据以上描述所做的润饰、修改或等同替换，均属于本发明所保护的范围。
