    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： A vehicle light emitting device including a light emitting element, a primary reflector, and a secondary reflector. A reflecting surface of the primary reflector has a shape of a substantially dome-shaped body of revolution formed by rotating about the optical axis Ax an ellipse E which has a primary focal point F1 which is a point near the light emitting element and a secondary focal point F2 which is a point near the reflecting surface. The primary reflector includes a belt-shaped region, which straddles a ring-shaped locus of the secondary focal point F2 and is configured as a light translucent portion, whereby reflected light from the primary reflector is caused to temporarily converge on the secondary focal point F2 in each cross-section of the body of revolution including the optical axis Ax and is thereafter caused to be incident on the secondary reflector as a diffused light.

    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.

    摘要： A distance from a center position of the light source to a rear focal point of a projection lens is smaller than a focal length of the projection lens. The light source is constituted by a line segment light source extended in a vehicle width direction. An opening portion is formed at a rear portion of a first reflector. A second reflector reflects light directed to a rear side from the light source to a front side to be proximate to an optical axis.
