Abstract
The power supply system for one or more lighting modules with light-emitting diodes comprises an electrical power source able to be connected to each lighting module via an electrical connection and a detection device to detect a connection direction of each lighting module. The detection device comprises an injection circuit to inject a setpoint current, a first comparison circuit to compute a voltage measured on the corresponding electrical connection following the injection of the setpoint with a first voltage threshold, and an inversion circuit to invert the polarity of the lighting module when the voltage measured on the corresponding electrical connection is greater than or equal to the first voltage threshold.
