    • The present invention relates to a flashlight having an auxiliary optical system that is rotation symmetrical to an optical axis, and that has an outer reflector part, an inner converging lens part, and a rear surface having a blind bore, and having a light-emitting diode (LED) arranged on a disk-shaped holder. In order to provide a flashlight having an auxiliary optical system, in which the emission characteristic can be set between a so-called moon setting and a focus setting, wherein the operability of the flashlight is to be as simple as possible and the desired setting can be found rapidly and reliably, according to the invention, the auxiliary optical system is displaceable relative to the LED delimited by two stops in such a manner that a substantially homogeneous light cone is generated in the case of contact of the auxiliary optical system on the holder.

    • An LED illumination module has a light-emitting diode and a rotationally symmetrical, one-piece, light-transparent adapter lens centered on a lens axis. This lens has an axially rearwardly open blind hole defined by a radially inwardly directed frustoconical light-receiving side surface and an axially rearwardly directed convex light-receiving base surface. The diode is axially shiftable in the hole. An axially forwardly directed convex light-output surface is coaxially surrounded by an axially forwardly directed and forwardly flaring frustoconical light-output surface. A radially outwardly directed and radially inwardly reflective surface extends generally from a front edge of the axially forwardly directed frustoconical light-output surface to a rear edge of the radially inwardly directed frustoconical surface.
    • LED照明模块具有以透镜轴为中心的发光二极管和旋转对称的,单件式的透光适配器透镜。 该透镜具有由径向向内指向的截头圆锥形光接收侧表面和轴向向后指向的凸形光接收基面限定的轴向向后敞开的盲孔。 二极管可以在孔中轴向移动。 轴向向前指向的凸出的光输出表面被轴向向前和向前扩张的截头圆锥形光输出表面同轴地包围。 径向向外和径向向内反射的表面通常从轴向向前定向的截头圆锥形光输出表面的前边缘延伸到径向向内指向的截头圆锥形表面的后边缘。
