    • 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.
    • 一种能够以至少两种模式形成至少两种类型的光分布的投影型车辆用前照灯结构,并且还能够以高精度控制其辐射光,并且在切换时保持最小的任何明显的差异 模式之间。 反射器的一部分被构造为可以与剩余反射部分分离的移动反射部分。 通常在移动反射部分后方设置附加的反射器。 当移动反射部分与剩余反射部分分离时,附加的反射器入射到来自光源的光。 从移动反射部分入射的光,剩余的反射部分和附加的反射器被向前反射到车辆前照灯的投影透镜,在车辆的行进路径之前的区域中提供照明。

    • As the annular translucent member, an annular lens formed from a peripheral edge portion of a convex-meniscus lens is disposed between a projection lens and a reflector along an outer peripheral edge of the projection lens. Direct light from a light source toward a space beyond the outer periphery of the projection lens is caused to illuminate forward of the lamp by the annular lens, thereby effectively utilizing light source luminous flux. In relation to the above, a shape of a back surface of the annular lens is formed into a spherical surface having its center at a luminescence center of the light source. Accordingly, direct light from the light source can travel straight without being deflected by a back surface of the annular lens, whereby a light deflection angle on a front surface of the annular lens can be calculated easily and with good accuracy.
    • 作为环状的半透明构件,由凸凹透镜的周缘部形成的环状透镜沿着投影透镜的外周边缘配置在投影透镜和反射体之间。 使从光源向投影透镜的外周的空间的直接光通过环形透镜照射到灯的前方,从而有效地利用光源光通量。 关于上述,环形透镜的背面的形状形成为其中心在光源的发光中心的球面。 因此,来自光源的直射光可以直线行进而不会被环形透镜的背面偏转,从而可以容易且准确地计算环形透镜前表面上的光偏转角。
