A headlight (1) comprising: a parabolic reflector (2) comprising an opening (2a), said parabolic reflector (2) being configured to reflect and distribute in a homogenous manner toward the opening (2a) at least a light beam (5a,5b); a transparent shield (3) to close said opening (2a); a bearing partition (4) arranged in the parabolic reflector (2), so to define a first sector of the reflector (15) and a second sector of the reflector (16) opposed to each other with respect to said bearing partition (4); at least a light source configured to generate: a first light beam (5a) pointed toward said first sector of the reflector (15); a second light beam (6a) pointed toward said second sector of the reflector (16); a third light beam (7a); a mask (8) comprising at least a partially transparent window (9) arranged so that said third light beam illuminates said window (9).

A vehicle head light control apparatus controls a lighting apparatus included in a headlight of a vehicle to avoid irradiating to an irradiation avoidance region which is a region overlaps with a detected object. The lighting apparatus can irradiate an irradiation region which is a set of irradiation sections. When the vehicle is in a manual driving state, irradiating to the irradiation sections included in an adjacent region which is a region adjacent to the irradiation avoidance region is reduced as a distance between the irradiation section and the irradiation avoidance region becomes shorter. When the vehicle is in an autonomous driving state, the adjacent region is not provided or the adjacent region becomes smaller as compared with a case where the vehicle is in the manual driving state.

The projector-type headlamp comprises a projection lens unit and a light source unit. A diffraction grating designed to eliminate chromatic aberrations is provided on at least part of a lens surface of the lens unit. When an x axis in the horizontal direction and a y axis in the vertical direction are defined on a plane perpendicular to the optical axis, R1 is the maximum y coordinate on the lens surface, and 0A<1, an area of the lens surface in which y<A.Math.R1 comprises a curved surface or a flat surface, at least partially provided with the diffraction grating, and an area of the lens surface in which yA.Math.R1 comprises a separate curved surface that has a power greater than the power of the curved surface or flat surface, and is not provided with a diffraction grating.
