Abstract (en)

[origin: WO2019207147A1] The invention relates to a light module (14) for projecting a pixelated light beam (16) comprising a high-resolution zone (20) and a low-resolution zone (22), said light module (14) comprising: an array (28) of light-emitting diodes (30); a projection optic (44) having an object focal plane (P); and an optical element (32) forming high-resolution object pixels from the light-emitting diodes (30) in the object focal plane (P); characterised in that the light module (14) comprises low-resolution light sources (36) different from the array (28) of light-emitting diodes (30), and a primary optical element (38) different from the intermediate optical element (32) for forming low-resolution object pixels in the object focal plane (P).
