Abstract
A device for projecting a light beam and having a mechanical actuator, notably for a motor vehicle, including an array of light sources able to emit light rays in order to form the light beam along an optical axis, each light source defining a component of the light beam which has an angle of resolution defined in a plane, the device including moreover a mechanical actuator configured for displacing at least one element of the device in such a way that the optical axis of the light beam is moved between at least two projection directions at a specified frequency of displacement, the projection directions forming between them an angle of displacement substantially coplanar with the angle of resolution, the angle of displacement being equal to a fraction of the angle of resolution of the beam.
