Abstract (en)
[origin: WO2022171705A1] Disclosed is a light source (100) of a matrix arrangement of light sources of a motor vehicle lighting module, comprising: a substrate (120) having an upper face (122), a lower face (121) opposite the upper face, and an electronic circuit (150); at least one light-emitting element (130) which is mounted on the upper face of the substrate and includes a light-emitting part; and an optical device for forming the light beams emitted by the light-emitting element; the lower face comprising connection contacts (151) connected to the electronic circuit, the electronic circuit being adapted to power the at least one light-emitting element; the light-emitting part of at least one light-emitting element having a surface area of less than 40,000 μm2; the beam-forming optical device having an optical element (140) on the upper face of the substrate and/or on the light-emitting part of the at least one light-emitting element.
