Definitions
- the invention relates to a lighting module for a motor vehicle, comprising a light source provided with a plurality of semiconductor emitters and optical means for shaping the light emitted by the light source.
- the luminance of at least one activatable zone is at least greater than 100 Cd / mm 2 , or even greater than 120 Cd / mm 2 .
- the optics for shaping light comprises at least two diopters.
- FIG. 3 illustrates a cross-sectional view of the light source of FIG. 2
- the electroluminescent rod 4 is a diode of a general vertical column shape, for example of hexagonal section.
- each diopter, or at least one of the diopters has diffractive patterns.
