  • Patent number: 7600903
    Abstract: In the invention, a light device is proposed equipped with a DC motor for causing the tilting of a pivoting plate, in addition, in the invention, a solution is proposed for preventing the DC motor from degrading too quickly. To this end, it is therefore proposed to limit, for example by means of an electronic control card, the supply current to the motor to a limitation threshold, at least during the phases in which the DC motor is functioning in locked torque.
