Definitions

  • the technical field of the invention is that of lighting modules for motor vehicles.
  • a motor vehicle is equipped with headlamps, or headlights, intended to illuminate the road in front of the vehicle, at night or in the case of reduced luminosity.
  • headlamps can generally be used in two lighting modes: a first mode “high beam” and a second mode “low beam”.
  • the "high beam” mode provides strong illumination of the road far ahead of the vehicle.
  • the "low beam” mode provides more limited road lighting, but still offers good visibility without dazzling other road users.
  • These two lighting modes are complementary.
  • the driver of the vehicle must manually switch modes depending on the circumstances, at the risk of inadvertently dazzle another user of the road. In practice, changing the lighting mode manually can be unreliable and sometimes dangerous.
  • the dipped beam mode provides visibility sometimes unsatisfactory for the driver of the vehicle.
