1. A light module comprising:
a fixed mount intended to act as a support for a light source;
a projection optic that has a focal plane and is designed to project a light beam from the light rays emitted by the light source;
a member for holding the projection optic, the member including:
a first support element;
a second support element that acts as a support for the projection optic;
with the second support element arranged so as to allow the thermal expansion of the projection optic, causing the focal plane to shift in a first direction;
the first support element exhibits a first coefficient of thermal expansion, the second support element exhibiting a second coefficient of thermal expansion which is different from the first coefficient of thermal expansion;
the first support element is connected on one side to the fixed mount and on the other side to the second support element so as to shift the second support element during the deformation of the first support element in a second direction opposite to the first direction; and
the second support element includes a first part and a second part which are fitted one in the other so as to form an accommodating space for the projection optic, one of the two parts supporting the projection optic on a first side of the projection optic and the other part comprising an elastically deformable member directly bearing on the projection optic on a second side on the opposite side from the first side.
