Abstract

The invention relates to a luminous device for an automotive vehicle. The illumines devices including a main bracket on which a first bracket and a second bracket are mounted, each of the first bracket and second bracket being mounted so as to be movable on the main bracket. The first bracket supporting a first lighting module and the second bracket supporting a second lighting module. The luminous device further includes a mechanical connection device which connects the first bracket to the second bracket. A first adjustment device cooperates with the mechanical connection device and being capable of causing a movement of the mechanical connection device in relation to the main bracket. A second adjustment device via which the second bracket is mounted on the mechanical connection device and that is capable of causing a movement of the second bracket in relation to the mechanical connection device.

First claim

What is claimed is:

1 . A luminous device for an automotive vehicle, comprising a main bracket on which a first bracket and a second bracket are mounted, each of the first bracket and second bracket being mounted so as to be movable on the main bracket; the first bracket supporting a first lighting module and the second bracket supporting a second lighting module;
a mechanical connection device which connects the first bracket to the second bracket; a first adjustment device cooperating with the mechanical connection device and being capable of causing a movement of the mechanical connection device in relation to the main bracket; a second adjustment device via which the second bracket is mounted on the mechanical connection device and that is capable of causing a movement of the second bracket in relation to the mechanical connection device; wherein the first adjustment device can cause a substantially vertical movement of the mechanical connection device in relation to the main bracket, with the substantially vertical movement being substantially perpendicular to an optical axis and causing simultaneous movement of the first bracket and the second bracket relative to the main bracket, and the mechanical connecting device includes a connecting rod connected to the first bracket at one end and to the second adjustment device at the opposite end, and the first adjustment device includes an actuator movable in translation and connected to a shaft of the mechanical connection device, the shaft being arranged to transform a translational movement of the actuator into a rotational movement of the first bracket around a first rotation axis and of the second bracket around a second rotation axis, and in that the actuator can cause the vertical translational movement of the mechanical connecting device.

2 . The luminous device for an automotive vehicle as claimed in claim 1 , wherein the first bracket is connected to the main bracket by two first ball-and-socket joints, the first ball-and-socket joints defining the first rotation axis about which the first bracket can pivot.

3 . The luminous device for an automotive vehicle as claimed in claim 1 , wherein the second bracket is connected to the main bracket by at least two second ball-and-socket joints, the second ball-and-socket joints defining the second rotation axis about which the second bracket can pivot.

4 . The luminous device for an automotive vehicle as claimed in claim 1 , wherein the first rotation axis and the second rotation axis are substantially parallel to one another.

5 . The luminous device for an automotive vehicle as claimed in claim 1 , wherein the actuator is movable in translation in a direction substantially parallel to a direction of extension of the connecting rod.

6 . The luminous device for an automotive vehicle as claimed in claim 5 , wherein the second bracket is connected, by a fastening member, to the second adjustment device, and wherein the second adjustment device is able to drive a displacement of the fastening member in relation to the one end.

7 . The luminous device for an automotive vehicle as claimed in claim 6 , wherein the second adjustment device includes a threaded screw seated in a threaded orifice of the second bracket, forming the fastening member, and wherein the mechanical connection device is mounted on the screw by a ball-and-socket joint.

8 . The luminous device for an automotive vehicle as claimed in claim 1 , further comprising a housing fastened to the main bracket, the first bracket and the second bracket, the first and second lighting modules, the first adjustment device and the second adjustment device being seated together in the housing, and a chassis to which the housing is fastened including fastening members for fastening the luminous device to the automotive vehicle.

9 . The luminous device for an automotive vehicle as claimed in claim 8 , wherein the housing is fastened to the chassis by a ball-and-socket joint, by a third adjustment device, and by a fourth adjustment device, the ball-and-socket joint, the third adjustment device and the fourth adjustment device forming a trihedron.

10 . The luminous device for an automotive vehicle as claimed in claim 1 , wherein the second lighting module is arranged to emit a second light beam with a flat cut-off.

11 . The luminous device for an automotive vehicle as claimed in claim 10 , wherein the first lighting module is arranged to emit a first segmented light beam, each segment of which can be controlled selectively, the first segmented light beam extending at least partially above the second light beam.
