Abstract

The invention provides an illumination device, preferably a reading lamp, which, on the one hand, has a compact design and, on the other hand, ensures a flexible illumination of objects, for which, in order to ensure an adequately high illuminance, high-power light sources can be used and which includes preferably a light source and a light-guiding element that can be pivoted and/or tilted around a pivoting/tilting point, which has at least one light-guiding axis and at least one light in-coupling surface as well as one light out-coupling surface, with the light-guiding element being arranged preferably in an axially displaceable manner in such a way that a free beam area can exist between the light source and the light in-coupling.
