发明名称 TORCH WITH A ROTATIONALLY SYMMETRICAL OPTICAL ATTACHMENT
摘要 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.
