Optical unit
An optical unit includes a first light source, a second light source, a rotary reflector rotating around its rotation axis while reflecting a first light emitted from the first light source, and a projection lens configured to project the first light reflected by the rotary reflector in a light irradiation direction of the optical unit. The second light source is disposed such that a second light emitted from the second light source is incident on the projection lens without being reflected by the rotary reflector. The projection lens is configured to project the second light in the light irradiation direction of the optical unit.
Cutoff mechanism comprising a bar carrying a permanent magnet
Cutoff mechanism for a motor vehicle headlight, that has a bar formed by an obturation plate carried by a movable appliance configured so as to move the plate in a plane and thus obscure a light beam to a greater or lesser extent so as to change the optical operating mode, further having a mechanism for actuating the movable appliance using an electromagnet having an induction coil associated with a ferromagnetic core, wherein the electromagnet has at least one ferromagnetic core fixed with respect to its induction coil and in that the movable appliance has at least one permanent magnet configured so as to cooperate magnetically with the ferromagnetic core.

Vehicle lamp device and light cut-off structure thereof
A vehicle lamp device and a light cut-off structure thereof are disclosed. The light cut-off structure includes a front cut-off edge, a rear cut-off edge, and a top surface. The front cut-off edge corresponds in position to the rear cut-off edge and the top surface is connected between the front and rear cut-off edges. A portion of the top surface is inclined along an inclination direction from the front cut-off edge toward the rear cut-off edge. The portion has a predetermined inclination angle relative to a horizontal plane or a lens optical axis. The predetermined inclination angle is greater than 0 degrees and less than 30 degrees. A lighting pattern with a cut-off line is formed when at least one emitted light is selectively shielded by the front cut-off edge. Therefore, the light concentration ratio can be significantly raised.
Cut-off mechanism for motor vehicle headlight, actuated by an electromagnet with two air gaps
Cut-off mechanisms for a motor vehicle headlight activated by an electromagnet with two gaps comprise a movable assembly that comprises a cut-off bar and a movable element, as well as an actuator motor comprising an electromagnet, the movable element being movable under the action of the electromagnet, against a return spring, between a near activation position and a remote rest position relative to a ferromagnetic core of the electromagnet, the movable element being configured to create an interruption in the continuity of a magnetic circuit formed by the ferromagnetic core, a metallic casing and the movable element, when said element comes near to the ferromagnetic core in the activation position.
