Title: (ZH) LED灯具之光学透镜
Abstract: front page image
(ZH)

本实用新型公开了一种LED灯具之光学透镜,其具有倒圆锥状之一透镜本体而组设于一固定座内,再与一LED发光源结合以形成一照明灯具,该透镜本体系包含:一平面部,设于该透镜本体之顶部,且该平面部的圆心位置系具有一圆槽;一投射圆锥,设于该透镜本体之底部,该投射圆锥的中心系具有一容置室以放置该LED发光源,该容置室与该圆槽互不相通,且该投射圆锥之外曲面系由同心圆设置的复数个曲面点所组成。据此,利用本实用新型可调整该LED发光源之发光角度、光度分布与照度分布,使照明效果更加集中且均匀;再者,该圆槽系可减少塑料成型时的缩水现象而提升成品质量。
