Abstract
Embodiments provide an illumination device comprising an elongated base and a pivotable elongated illumination unit. Said pivotable elongated illumination unit is mounted to be pivotable about a longitudinal axis by means of at least one joint. Both the elongated base and the pivotable elongated illumination unit extend in parallel with said longitudinal axis. In particular, the longitudinal extension of the pivotable elongated illumination unit is limited by two opposing lateral faces. The illumination unit includes at least two illumination elements arranged along the pivotable axis, so that a distance between two neighboring light emitting elements corresponds to 1.5 to 2.5 times the distance between a light emitting element that is positioned adjacently to a lateral face and the corresponding lateral face.
