Abstract

An article of manufacture comprises a thin film solid state lighting device, such as an organic light emitting diode (OLED) device, having a planar light emitting side and an opposite planar mounting side and including electrodes disposed on the planar mounting side of the thin film solid state lighting device, the electrodes including a magnetic material configured to conductively convey electrical drive current to drive the thin film solid state lighting device to emit light at the planar light emitting principal side. The article of manufacture may further comprise a fixture having a planar surface with magnets arranged to mate with the electrodes to magnetically secure the thin film solid state lighting device with the fixture and to concurrently form electrically conductive paths including the magnetic material of the electrodes configured to conductively convey electrical drive current. Thus this magnetic connection provides both mechanical support and electrical conduction path.
