A road surface drawing lamp unit includes a light source module and an optical system. In the light source module, a plurality of light sources which correspond individually to drawing patterns, each of which is long in a first direction which is a width direction of a road and short in a second direction which intersects the width direction of the road and an emitting axis of the light sources, are arranged so that the drawing patterns are drawn at a plurality of locations on the road along the second direction, and the light sources are formed so as to be turned on and off independently. The optical system emits light emitted from the light sources to the front.

The light device contains first and second rows of light sources wherein rows are arranged next to each other, collimating elements associated with the light sources to convert their generated light to collimated light, and a light guide to bind the collimated light and emit it from the light guide output surface. Between the collimating element output and the light guide output surface, an optical means is arranged to divide the collimated light to at least two individual, spatially separated light beams, wherein the first light beam is formed by part of the collimated light passing by the optical means, and the second light beam is produced by passing another part of the collimated light through a refractive surface of the optical means. The first and second light beams are displayed on the output surface in the form of separate bands, namely the first and second band (A, B).

A light emission module, in particular for a motor vehicle. The module includes a substrate comprising a curved main portion extending in a longitudinal direction. A plurality of electroluminescent elements is arranged on the substrate and configured to emit light rays when supplied with electrical energy. The electroluminescent elements are distributed along the longitudinal direction, and a control assembly suitable for regulating the electrical energy supplied to the electroluminescent elements. The control assembly has a mode of operation in which the control assembly is configured to supply the electroluminescent elements with respective electrical energies and/or powers determined at least as a function of respective main directions of light emission of the electroluminescent elements to obtain at least two maximum light intensities emitted by the electroluminescent elements in the corresponding main direction of emission which are different along the longitudinal direction of the substrate.

A headlight for a motor vehicle includes a first lighting device and a second lighting device, which are provided for generating a dipped beam. The first lighting device, when switched on, generates a first light distribution on the ground in front of the motor vehicle, and the second lighting device, when switched on, generates a second light distribution on the ground in front of the motor vehicle. The first lighting device is permanently switched on when the dipped beam is activated, and the second lighting device is switched off when the dipped beam is activated and when a predetermined condition is met. The second lighting device is always switched from being switched off to being switched on when the speed of the motor vehicle is greater than or equal to a specified speed threshold.
