<p>Apparatus for adjusting alternating-current lighting devices (LD), which comprises at least one input connector (IC) for the electric connection to an alternating-current source and an output connector (OC) for the electric connection to one or more alternating-current lighting devices (LD), wherein the input connector (IC) and the output connector (OC) are electrically connected through at least one voltage regulator (VR), characterized in that the voltage regulator (VR) comprises a transformer (T) electrically connected to the input connector (IC) and a plurality of controlled switches (CS) connected in parallel between the taps of a winding of the transformer (T) and the output connector (OC), so that the output voltage (Vo) of the output connector (OC) can be varied with respect to the input voltage (Vi) of the input connector (IC) by closing at least one controlled switch (CS), wherein the control gates of the controlled switches (CS) are connected through at least one control line (CL) to an electronic control unit (CU) which is connected to one or more light sensors (LS) suitable for measuring the light intensity (LI) in the environment comprising the lighting devices (LD). The present invention also relates to a process which can be carried out through said apparatus.</p> |
