Abstract: A lighting module for a motor vehicle, including a first lighting submodule with a light source that is able to form a first light beam, a second lighting submodule that is able to form a second light beam, a second projecting lens for projecting the second light beam, adjoining the first projecting lens, and an optical device configured to return, towards the second projecting lens, light rays coming directly from the light source of the first lighting submodule and passing in front of the reflective surface of the first lighting module so as to give the second projecting lens an illuminated appearance while the second lighting submodule is off.

Abstract: An assembly for projecting a light beam includes a first sub-assembly for generating light rays, and a second sub-assembly comprising a converging lens. The first sub-assembly is arranged upstream of the second sub-assembly such that the light rays coming from the first sub-assembly are sent to the converging lens and such that the light rays emerging from the converging lens form the light beam. According to the invention, the projection assembly includes at least one connection system connecting the first sub-assembly to the second sub-assembly and allowing at least one translational movement of the first sub-assembly and the second sub-assembly relative to each other in a first longitudinal direction (X). Moreover, the connection system comprises a locking member that is movable between a first position in which the first sub-assembly and the second sub-assembly are motionless with respect to each other and a second position enabling the translational movement.

Abstract: An optical module, used for lighting and/or signalling purposes for a motor vehicle, includes a support delimiting a compartment for receiving a functional component such as a fan. A clamping element, preferably produced as a single part, can be used to block an opening of the compartment and lock the component in its operational position. The clamping element, separate from the support and provided with two arms, is engaged and clipped on against at least one engaging protrusion formed laterally on the support in order to achieve the locking. An elastic return effect of at least one of the two arms allows the clamping element to be engaged at the rear of the protrusion and held in place. For unlocking, a flexible actuation portion formed in the clamping element can be actuated in order to move one of the two arms outwards and allow unclipping to take place.
