Abandoned for a very long time, because of the complexity of their Multi-Carrier techniques (Multi Carrier Modulation, MCM or Orthogonal Frequency Division Multiplexing OFDM), nowadays, the OFDM has become the strategic choice of several systems modern digital products. Its simplicity and flexibility, as well as the transmission, make them particularly interesting for communication systems. Inspired from Telecommunications field, especially from the OFDM Techniques, the aim of this paper, is to propose a model of street lighting system based on OFDM operations, this technique is used here control and to switch On/Off the street lamps and to launch a proposed waveform of voltage command of lighting when pedestrian or vehicle detections are occurred, even in cases of multi detections in streets or in other words branches of street lamps. This proposed model will allow us to illuminate intelligently by using a new strategy of voltage command of lighting and to reduce considerably the rate of power consumption during the lighting for smart lighting and so, contributing on having a smart city.
