Abstract
A lighting module has a conducting track which is used to provide a current to lighting elements. The conducting track is also used as a source of a varying electromagnetic field for inductive power transfer, so that an external device may harvest energy from that field. A driver is used for providing a time-varying current which is adapted to illuminate the lighting elements and, in combination with the track configuration, is adapted to generate a varying electromagnetic field for inductive power transfer for energy harvesting by an external device.
