Disclosed herein is a lighting system, in particular for an avionics apparatus, having at least a light source and a control unit coupled to the light source and controlling operation thereof based on a management PWM signal; the management PWM signal may have a shape such as to limit radio frequency emissions. According to an embodiment, the lighting system has an interface unit coupled to the light source and receiving the management PWM signal from the control unit; during a lighting management mode, the management PWM signal carries management information for controlling the light source, and the interface unit is operable to decode the management information, for driving the light source; in particular, the control unit codes the management information using a first waveform parameter of the management PWM signal, and at least a second waveform parameter of the management PWM signal, different from the first waveform parameter. According to a further embodiment, the lighting system has at least one storage element coupled to the light source, and a transmission protocol is associated to the management PWM signal, envisaging a bidirectional communication between the control unit and the interface unit, by means of which management data are read from, and/or written to, the storage element.
