Abstract
The invention relates to a motor vehicle light module comprising: —a part comprising a plurality of light guides, each of said light guides extending between an input diopter of the same guide and an output, the adjacent light guides joining to one another by a material junction; —several light sources arranged opposite the input diopters of all or a portion of the light guides; and—a projection system downstream from the guide outputs that has a focal surface (F) projecting an image of any light ray passing through the focal surface. According to the invention, the light module comprises at least two guides of which the distance (d1) between the focal surface (F) and the junction of said two guides is greater than the distance (d2) between the focal surface (F) and the junction of the other guides.
