Device for dehumidifying a closed casing. The device for dehumidifying comprises a box comprising an inlet communicating with the interior of the closed casing and an outlet, a heating module able to be controlled to generate heat, a desiccant configured to adsorb moisture when it is not heated by the heating module and to return adsorbed moisture by desorption when it is heated by the heating module, a mobile plug able to be moved to alternately open and close the inlet and the outlet, a bias spring configured to move the mobile plug when the heating module does not heat the desiccant and a shape memory alloy spring configured to move the mobile plug when the heating module heats the desiccant, said shape memory alloy spring being able to be heated by the heating module at the same time as the desiccant. The device for dehumidifying is suited for dehumidifying any type of closed casing, it is cost efficient both in design and in power consumption, and it is easy to implement thanks to its small size and its simple design.

This disclosure relates to an electric actuator to render optical elements movable. The electrical actuator generally has a motor, a mechanical transmission assembly having an endless screw, a support element of the endless screw, a drive mechanism, and a return mechanism. The motor is configured to drive the mechanical transmission assembly and the mechanical transmission assembly is configured to drive the drive mechanism, wherein the return mechanism exerts an axial pressure against the endless screw in such a way as to press the endless screw against the support element. The disclosure also relates to an assembly having a movable optical element and an electric actuator of the movable optical element as described above.

Actuator for rendering at least one optical element movable

The invention relates to a spotlight () for a motor vehicle that has a light source () producing a beam of light which is directed along a first axis (X) intended to be oriented towards the front of the vehicle and a lens (), wherein the light source () projects all of the beam directly onto the lens () without reflection nor obturation, and the lens () is arranged to move in rotation about a second axis (Z) intended to be oriented towards the top of the vehicle.
