Abstract:
1. A headlight unit comprising light source, a mirror exhibiting a reflecting surface for reflecting light signals produced by the light source, and a transparent optical deflection element exhibiting an admission face for the reflected light signals and an exit face for the reflected light signals, the transparent optical deflection element being positioned in front of the mirror, the mirror being capable of interacting with the light source in order to generate a beam bounded by a cut-off line, and the optical deflection element being capable of providing a horizontal displacement of the light signals produced by the light source and reflected by the mirror, without modifying the vertical distribution of the light signals, and at least one detachment element arranged on at least the reflecting surface of the mirror or a surface of the optical deflection element reached by the light signals in order to obtain a cut- off line of the light beam that is not flat, wherein the at least one detachment element comprises at least one prism arranged on the transparent optical deflection element, and the transparent optical deflection element includes a surface with an admission face having arranged thereon vertical strips, the at least one prism being arranged on a vertical strip of the vertical strips and being part of the transparent optical deflection element.
