Description

一种内置脚位的直下式光学透镜 技术领域
[0001] 本实用新型涉及背光模组技术领域， 具体地， 涉及一种内置脚位的直下式光学 透镜。
背景技术
[0002] 目前常用的背光模组中采用的 LED灯条的基本结构是在 PCB板上焊接 LED灯， 在 LED灯上罩上若干透镜。 透镜通过设置在其下底面的脚位安装在所述 PCB板上 。 现有的常规直下式透镜， 与之配合的 PCB板的宽度为 20.0mm， 导致灯条的生 产成本居高不下。 为此， 许多生产厂家采用单面覆铜取代双面覆铜， 或采用劣 质的 CM-IPCB板， 导致灯条的 PCB板出现翘起变形， 易老化等现象， 降低了产 品的质量。
技术问题
[0003] 为了克服现有技术的不足， 本实用新型提供了一种内置脚位的直下式光学透镜 ， 将透镜的脚位由透镜底面周边改为透镜底面内部， 从而使得与之配合的 PCB板 的宽度能够降低至 13mm,大大降低了灯条的成本。
问题的解决方案
技术解决方案
[0004] 本实用新型的技术方案如下： 一种内置脚位的直下式光学透镜， 包括环形底座 及沿底座周边拱起的圆弧形顶面， 所述圆弧形顶面的内侧设置有呈等边三角形 排列的三个脚位。
[0005] 三个所述脚位的中心与所述环形底座的中心重合。
[0006] 较佳地， 任意两个所述脚位外边缘的最远距离为 12-20mm。
[0007] 较佳地， 两个所述脚位外边缘的最远距离为 13mm。
