Abstract

According to the present invention, the luminous flux emitted by lamps (4), in particular discharge lamps, is adjusted by using a remote electronic control unit (2) and at least one local electronic control unit (3,8) in one-way communication with each other through the electric power line (5), used as a communication means; the information to be communicated is associated with variations in the root-mean-square value of the power voltage. Typically, the remote electronic control unit (2) is dedicated to a plurality of lamps (4), whereas the local electronic control unit (3,8) is dedicated to one lamp (4) only; therefore, there is typically a plurality of local electronic control units (3,8); the remote unit (2) and the local units (3,8) are connected to one another through electric power lines (5).
