上述装置安装在手电筒后， LED发光源 11相对固定的安装在手 电筒本体上， 而反光镜 12固定安装在手电筒的可沿手电筒长度方向 活动的前盖上，如此， 当反光镜 12带动凸透镜组件 13远离 LED发光 源 11活动，至 LED发光源 11位于导向盲孔 133的开口外时， 如图 3a 所示， 光线从 LED发光源 11射出后， 周边的光线经过支撑柱 132的 折射后， 再经反光镜 12反射后射出， 中间的发散光线直接经过凸透 镜 131的聚光作用，形成较为聚拢的光线束，适应于较远距离的照射； 本实用新型中， 可以将反射镜 12的焦点与凸透镜 131的焦点重合， LED发光源 11位于其二者焦点处时， 凸透镜 131将中间的光折射成 平行光， 而两侧的未经凸透镜 131折射的光线则被反光镜 12反射成 说 明 书
平行光， 由此， 可将大于 88%的光束利用与远距离照明。 当反光镜 12 带动凸透镜组件 1 3靠近 LED发光源 11活动，至 LED发光源位于导向 盲孔 1 33内并靠近凸透镜 1 31的下表面时， 如图 3b , 光线从 LED发 光源 11射出后， 周边的光线经过支撑柱 1 32的折射后， 再经反光镜 12反射后射出向反光镜 12的轴线聚拢， 而中间的发散光线经过凸透 镜 1 31作用后射出， 反射镜 12将两边未经过凸透镜 1 31的光线向前 反射， 由此， 实现光的泛焦， 产生较为均匀的月亮光， 适用于近距离 的大范围照明。
当然， 上述凸透镜组件 1 3的支撑柱 1 32还可以是圓台状结构， 相应的， 其上的导向盲孔 1 33也为与之匹配的圆台状结构， 其二者圆 台的母线与其轴线的夹角 a为 1 3-20° , 可以才艮据实际情况， 优先选 择 15或 16。 。

当反光镜 22带动凸透镜组件 23远离 LED发光源 21移动，至 LED 发光源 21位于反光镜 22的下端开口以外时， 如图 6a所示， 光线从 LED发光源 21射出， 位于周边的光线经过反光镜 22反射， 在经过支 撑板 232折射后形成相对较为聚拢的光束射出，中间的光线经由凸透 镜 231处理后， 实现聚拢， 适应于较远距离的照射， 当凸透镜 2 31的 焦点与反光镜 22的焦点重合，且 LED发光源 21位于其二者的焦点时， 对光线的利用率最大。当反光镜 22带动凸透镜组件 2 3靠近 LED发光 源 21移动， 至 LED发光源 21位于反光镜 22内部并靠近凸透镜 231 的下表面， 如图 6b所示， 周边的光线经由反光镜 22反射， 在经由支 撑板 232折射后射出， 反射镜 22将两边未经过凸透镜 231的光线向 前反射， 由此， 实现光的泛焦， 产生较为均匀的月亮光， 适用于近距 离的大范围照明。
凸透镜组件 23中， 支撑板 232的外表面切面与其径向截面之间 的夹角 b为 35-40° , 其中以 36。 最为合适。 相对于现有的同类光学 组套，上述结构可以针对距离的远近，形成相对较为良好的照射特性， 避免了光线的发散浪费.同时此结构还可以沿着反射镜的轴线，拉长 或减小光源与反光镜及凸透镜组件之间的距离 ,以实现远近距离照明 的快速转换，形成相对较为良好的照射特性,避免了光线的发散浪费。 说 明 书 上述两种光学组套的反光镜由塑料或铝合金，在其作为反光面的 内表面采用电镀、化学镀、 真空镀等表面处理工艺设置有一层反光效 果较佳的镀膜层。
上述凸透镜组件的凸透镜的上表面（也就是光线射出面）的曲率 半径小于下表面（也就是光线的入射面）的曲率半径； 凸透镜的直径 相对于光学组套的直径的比例在 1比 1. 3与 1比 1. 6之间，优选为 1 比 1. 4; 凸透镜的厚度相对于光学组套的高度的比例在 1比 7与 1比 4之间，优选为 1比 5; 光学组套的直径相对于其高度的比例在 1与 1 之间，优选在 1. 5与 1. 75之间。
