Abstract
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.
