Light module for a motor vehicle

A luminous device comprising a luminous module, with the luminous module including at least one light source configured to emit light rays, at least one collector associated with the at least one light source, the at least one collector being configured to collect and direct the light rays from the at least one light source toward at least one exit optical element, the at least one exit optical element configured to transmit the light rays toward the outside of the vehicle to form a light beam, and a system for lateral relative movement of the at least one collector and the at least one associated light source relative to the at least one exit optical element in such a way as to cause the light beam to move laterally, the system for lateral relative movement includes a pivot connection of center A and axis AE and a ball joint of center D which are arranged laterally on either side of the at least one exit optical element, a pivot connection of center B and a pivot connection or ball joint of center C which are arranged laterally on either side of the plurality of collectors, the pivot connection or connections having an axis parallel to the axis AE, two parallel connecting rods with the same length, each respectively connecting the pivot connection of center A and the pivot connection of center B, and the ball joint of center D and the pivot connection or ball joint of center C in such a way as to form a parallelogram ABCD, a primary actuator configured to rotate the pivot connection of center A in a substantially transverse direction in such a way as to transversely move the plurality of collectors, and a primary annular linear connection of center F connecting the primary actuator to one of the connecting rods to form a primary crank.
