摘要： A shade driving unit is provided below a discharge bulb, and a fixed shade for covering a movable shade is provided close to the front side of the movable shade to conceal substantially the shade moving mechanism of the shade driving unit. Moreover, the shade leg portion of the fixed shade is fitted to a fixed shade-leg fitting projection formed below a reflector from its rear side to conceal substantially the mounting structure. Further, a pair of lateral upright walls extending from the fixed shade-leg fitting projection is formed below the reflector. The shade moving mechanism can thus be substantially concealed from either side of the fixed shade, even from a laterally shifted viewpoint from the front of the lamp.
摘要翻译：荫罩驱动单元设置在放电灯泡的下方，并且用于覆盖可动阴影的固定遮光板设置在可移动遮光板的前侧附近，以基本上隐藏灯罩驱动单元的灯罩移动机构。此外，固定遮光罩的遮光部分嵌入从后侧形成在反射器下方的固定遮光片配合突起，以基本上隐藏安装结构。此外，从反射器下方形成从固定阴影配合突起延伸的一对侧向立壁。因此，即使从灯的前方侧向偏移的观点，遮光移动机构也可以从固定遮光板的任一侧基本上隐藏。

摘要： The light distribution of a vehicle headlamp can be changed between various modes, including a basic mode and a motorway mode. In the basic mode, shaded region changeover means block a high light intensity region, and deflection control means controls a lamp optical axis Lx to a straight travel direction. In the motorway mode, the shaded region changeover means does not block the high light intensity region, and the deflection control means controls deflection of the lamp optical axis to a host vehicle lane side. A light distribution in which the high light intensity region faces a far distance ahead of the host vehicle lane can be obtained, and the host vehicle lane is brightly illuminated without dazzling a driver of a preceding vehicle or an oncoming vehicle. Accordingly, illumination suited to the motorway mode during high speed and medium speed travel can be achieved.
摘要翻译：可以在各种模式之间改变车辆前照灯的光分布，包括基本模式和高速公路模式。在基本模式中，阴影区域切换装置阻挡高光强度区域，并且偏转控制装置将灯光轴Lx控制到直线行进方向。在高速公路模式中，阴影区域切换装置不阻挡高光强度区域，偏转控制装置控制灯光轴向主车辆车道侧的偏转。可以获得其中高光强区域面对主车道前方远的距离的配光，并且主车辆车道被明亮地照亮，而不会使前方车辆或迎面而来的车辆的驾驶员眩目。因此，可以实现在高速和中速行驶期间适合于高速公路模式的照明。

摘要： An automotive headlamp employing a discharge lamp as its light source in which the emission of harmful ultraviolet ray is eliminated in the output light beam. The headlamp includes a lamp body, a reflector mounted in the lamp body, and a discharge bulb mounted in a bulb insertion hole in the rear portion of the reflector. The discharge bulb is composed of a lamp base, a pair of long and short lead supports projecting forward from the lamp base, the discharge lamp, a pair of lead wires extending in respective forward and rearward directions from front and rear end portions of the discharge lamp, and forward and rear metal supports welded to the long and short lead supports and to respective ones of the lead wires so as to support the discharge lamp at its opposite ends on the long and short lead supports. The forward end of the longer lead support terminates at a position substantially corresponding to a front end edge of the front portion of the discharge lamp. An ultraviolet-ray shielding globe encloses the discharge lamp so as to cut ultraviolet rays from light emitted by the discharge lamp. A front end portion of the ultraviolet-ray shielding globe is tapered so as not to interfere with light reflected from a circumferential edge portion of the reflector around the bulb insertion hole.

摘要： A beam switching device 24 is provided for switching between a low beam and a high beam by rotating a shade 22 for screening part of incident light given off from a discharge illuminant portion 18a to a reflecting surface 20a of a reflector 20. The shade 22 rotates about a rotational axis A extending in a direction which inclines a predetermined angle &THgr; relative to a horizontal plane. A rotational locus of the shade 22 can be inclined relative to a vertical plane. The beam switching device 24 can also be inclined relative to the vertical plane. Thus, a vertical dimension h from an optical axis Ax to a lower end f the beam switching device 24 is made short.

摘要： A vehicle headlamp is equipped with a shade driving unit 24 for moving a movable shade 22, which is capable of shading part of light incident on a reflector 20 from the discharge light emitting portion 18a of a discharge bulb 18, between at least two positions where the incident light is shed in different degrees. The discharge bulb 18 is fixedly supported by the reflector 30 via a bulb supporting base 26 and the movable shade 22 and the shade driving unit 24 are fitted to the bulb supporting base 26. Thus, the light source bulb 18, the movable shade 22 and the shade driving unit 24 together with the bulb supporting base 26 can be operated integrally as a unit. The unit is prefabricated before being fitted to the reflector 20 to facilitate the assembling of the lamp. Moreover, the precision of placement of the movable shade 22 with respect to the discharge light emitting portion 18a can also be improved.
