    • A vehicle headlamp is provided. The vehicle headlamp includes a projection-type light source unit housed in a lamp chamber. The light source unit includes a projection lens; a shade; a light emitting diode (LED) light source; a reflector; and an optical element. The LED light source includes a substrate; an LED chip disposed on the substrate such that the LED chip is oriented in a direction substantially perpendicular to an optical axis of the light source unit; and a cover member. A region of the cover member includes concave and convex portions so as to diffuse light transmitted through the cover member. The reflector reflects and guides the light from the LED light source onto a rear focus of the projection lens. The optical element guides the diffused light transmitted through the cover toward a front side of the vehicle headlamp so as to form an overhead light distribution.
    • 提供车辆前照灯。 车辆前照灯包括容纳在灯室中的投影型光源单元。 光源单元包括投影透镜; 阴影; 发光二极管(LED)光源; 反射器 和光学元件。 LED光源包括基板; 设置在所述基板上的LED芯片,使得所述LED芯片在与所述光源单元的光轴基本垂直的方向上取向; 和盖构件。 盖构件的区域包括凹部和凸部,以便扩散透过盖构件的光。 反射器将来自LED光源的光反射并引导到投影透镜的后焦点上。 光学元件将透过盖的漫射光引向车辆前照灯的前侧,以形成顶部光分布。

    • An automobile headlamp includes a plurality of projection light source units disposed in a lamp chamber. Each of the plurality of projection light source units includes a projection lens; a cut-off line forming shade extending approximately horizontally and forward such that an extending tip section thereof is located in a vicinity of a rearward focal point of the projection lens; a light-emitting element as a light source provided on both upper and lower sides of the shade; and a reflector, which reflects light emitted from the light-emitting element to be guided to the projection lens, provided on both upper and lower sides of the shade. A low-beam distribution pattern having a predetermined cut-off line is formed by a light source unit section on an upper side formed of the projection lens, the shade, the light-emitting element on the upper side, and the reflector on the upper side. An additional high-beam distribution pattern having a lower end cut-off line which approximately coincides with the predetermined cut-off line is formed by the light source unit section on a lower side formed of the projection lens, the shade, the light-emitting element on the lower side, and the reflector on the lower side. At least one of the plurality of projection light source units has an optical axis set to be parallel to an optical axis of the headlamp and at least one of the plurality of projection light source units has an optical axis set to be slightly tilted forward and downward with respect to the optical axis of the headlamp.
    • 汽车前照灯包括设置在灯室中的多个投影光源单元。 多个投影光源单元中的每一个包括投影透镜; 大致水平向前延伸的切割线形成罩,使得其延伸的顶端部分位于投影透镜的后焦点附近; 作为光源的发光元件设置在灯罩的上下两侧; 以及设置在灯罩的上下两侧的反射器,其将从被引导到投影透镜的发光元件发射的光反射。 具有预定截止线的近光束分布图案由在投影透镜,遮光罩,上侧的发光元件和上部的反射器形成的上侧上的光源单元部分形成 侧。 具有与预定截止线近似一致的下端截止线的附加的远光分布图案由形成在投影透镜的下侧上的光源单元部分,阴影,发光 下侧的元件和下侧的反射器。 多个投影光源单元中的至少一个具有设置为与头灯的光轴平行的光轴,并且多个投影光源单元中的至少一个具有设置为向前和向下稍微倾斜的光轴 相对于前照灯的光轴。

    • A lamp unit is provided. The lamp unit includes a light emitting element disposed on an optical axis so as to face in a direction substantially orthogonal to the optical axis, a first reflector facing the light emitting element to forwardly reflect light from the light emitting element, and a direct light control member disposed in front of the light emitting element for controlling direct light directed toward a region in front of the first reflector from the light emitting element without being incident on the first reflector. The direct light control member includes a first lens portion which deflects a first portion of the direct light in a direction approaching the optical axis, and an extended portion extending from the first lens portion. The extended portion controls a second portion of the direct light differently from the first lens portion.
    • 提供灯单元。 灯单元包括设置在光轴上的发光元件,以便在与光轴基本正交的方向上面对第一反射器,面向发光元件以向前反射来自发光元件的光,以及直接光控制 配置在所述发光元件前面的元件,用于控制从所述发光元件朝向所述第一反射器前方的区域的直接光,而不会入射在所述第一反射器上。 直接光控制构件包括:第一透镜部,其使直接光的第一部分沿接近光轴的方向偏转;以及延伸部,其从第一透镜部延伸。 延伸部分控制与第一透镜部分不同的直接光的第二部分。
