摘要： A projection-type vehicular headlamp structure that is capable of forming at least two types of light distribution in at least two modes, and is also capable of controlling the radiated light thereof with high precision in addition to keeping to a minimum any noticeable difference when switching between modes. A portion of a reflector is structured as a mobile reflection portion which may separate from a remaining reflective portion. An additional reflector is disposed generally behind the mobile reflective portion. The additional reflector is incident to light from a light source when the mobile reflective portion is separated from the remaining reflective portion. Light incident from the mobile reflective portion, the remaining reflective portion, and the additional reflector is reflected forward to a projection lens of the vehicular headlamp, providing illumination in the area preceding a vehicle's traveling path.

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.

摘要： Light emitted from a light source 12a is sequentially reflected on a first, second, and third additional reflectors in this order. By emitting light in the order of the reflectors, this allows the light to be parallel to an optical axis by an additional lens. Accordingly, it is possible to increase the light-emitting area of the entire headlamp, thereby improving the appearance of the headlamp with respect to the driver of the oncoming vehicle. The additional lens is formed to have a substantially wedge-shaped cross-section, and is provided along the surface shape of a projection lens. Furthermore, since the light emitted from the light source is sequentially reflected by the first, second, and third additional reflectors in this order, the light emitted from the light source can be focused and the quantity of the light passing through the additional lens is not excessively increased.
