Abstract

Adaptable subordination system to the motorized control of the light dimmers, intended to ensure a constant level of useful lighting, characterized in that it comprises means that supply an error signal 3 proportional to the difference between the useful lighting level and a level of reference lighting, which cooperate with means for converting said error signal into an actuating pulse applied to organs that control, on the one hand, the start-up and dragging of the motor coupled to the potentiometer of the grader in one or the other direction, according to the sign of the error signal, and on the other hand, the duration of operation of said motor, according to the amplitude of said error signal.
