Abstract

The present invention relates to a lighting system comprising a base part (12) with at least one primary coil (18), and at least one light module (13, 14) with a secondary coil (26) adapted to inductively interact with the primary coil (18). The lighting system is characterized in that said base part (12) comprises a substrate (50) carrying said primary coil (18), the winding of which lying in one plane and forming a flat coupling area (16); the winding of the second coil (26) lies in one plane; and said light module (13, 14) comprises at least one light element (20) and a flat bottom surface, so that the light module (13, 14) is placeable with its flat surface on the flat coupling area (16).
