摘要： An automotive headlamp apparatus comprises: a lamp unit configured to be capable of forming an additional light distribution pattern that includes an upper area above the cut-off line of a light distribution pattern for low beam and that is divided into a plurality of individual patterns; and a controller configured to control formation of each of the individual patterns in accordance with presence of a forward vehicle. The controller reduces the illuminance of an individual pattern overlapping an area where a forward vehicle is present and increases the illuminance of at least one of other individual patterns.

摘要： A lamp unit of a vehicular headlamp includes a projection lens with an optical axis; a light source formed from a semiconductor light-emitting element; a first reflector that reflects light from the light source so as to condense such light on or near the optical axis; and a shade positioned between the light source and the projection lens so as to extend along the optical axis direction. The shade shields part of the light reflected by the first reflector. In the lamp unit of the vehicular headlamp, a shielding surface extends rearward from a front end of the shade, where the shade is positioned near a rearward focal point Rf of the projection lens. The shielding surfaces serve as a second reflector that reflects light from the first reflector toward the projection lens. In addition, a transparent portion is formed on part of the second reflector such that part of the light reflected by the first reflector passes downward of the rearward focal point of the projection lens and is then incident to the projection lens.
