    • A vehicular headlamp that forms a predetermined light distribution pattern in front of the lamp by light that is radiated from a projector-type lamp unit. The projector-type lamp unit includes a projection lens provided on the optical axis that extends in the longitudinal direction of a vehicle and passes through substantially the center of the projection lens, a light source bulb provided behind the rear focal point of the projection lens, and a reflector which condenses and reflects light from the light source bulb toward the optical axis in the forward direction; and the light source bulb is disposed in the reflector at a point which is at a distance from the optical axis in an obliquely downward direction.
    • 一种车辆前照灯,其通过从投影仪型灯单元辐射的光在灯前面形成预定的配光图案。 投影型灯单元包括设置在光轴上的投影透镜,该投影透镜在车辆的纵向方向上延伸并且大致穿过投影透镜的中心,设置在投影透镜的后焦点后面的光源灯泡, 以及反射器,其将来自光源灯泡的光在向前的方向上朝向光轴聚光并反射; 并且光源灯泡设置在反射器中的与光轴相距一定距离处的倾斜向下的方向。

    • A light source bulb is fixedly inserted into a lateral direction to the optical axis Ax at a position below an optical axis Ax. Accordingly, a region lateral to the optical axis Ax on a reflection surface of the reflector can be effectively utilized for light distribution control. Furthermore, a first additional reflector having a reflection surface of substantially-spheroidal shape whose first focal point is at a position coincident with the light source is disposed at a position above the optical axis Ax. A second additional reflector 36 having a reflection surface of a substantially-parabolic vertical cross-sectional profile whose focal point is coincident with a second focal point of the first additional reflector is disposed at a position below the optical axis. As a result, light from the light source is illuminated forward without passing through a projection lens.
    • 光源灯泡在光轴Ax下方的位置沿光轴Ax的横向方向固定地插入。 因此,可以有效地利用反射器的反射面上的光轴Ax侧面的区域进行配光控制。 此外,具有第一焦点位于与光源重合的位置的具有大致球状的反射面的第一附加反射体设置在光轴Ax上方的位置。 具有基本上抛物面的垂直横截面轮廓的反射表面的第二附加反射器36的焦点与第一附加反射体的第二焦点重合设置在光轴下方的位置。 结果,来自光源的光线向前照射而不通过投影透镜。
