Abstract The present invention relates to a flashlight having an auxiliary optical system, which is rotationally symmetric to an optical axis, and which has an outer reflector part, an inner converging lens part, and a rear surface having a pocket borehole, and having a light-emitting diode (LED) arranged on a disc-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 in relation 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. |
