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： Optical axes are simultaneously adjusted by tiltably mounting a plurality of lighting device units on a common unit support member. A rectilinear propagation blocking member of each lighting device unit is fixed with screw via the elastic bush to the unit support member, so that the optical axis can be adjusted. Due to the above structure, even when the accuracy of shapes of the rectilinear propagation blocking member and the unit support member are not sufficiently ensured and also even when the accuracy of the attaching work can not be sufficiently ensured, the optical axes of the lighting device units can be arranged in order by adjusting the optical axis of the rectilinear propagation blocking member.

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.

The vehicle headlamp displaces the reflector from a first position to a second position which is upward and rearward from the base member. The vehicle headlamp can facilitate obtaining a light distribution suitable for driving on a motorway or in wet conditions.

摘要： A vehicle headlamp is provided with: a projector lens; a light source bulb; a reflector for reflecting direct light from the light source bulb to the front side; a movable shade; and an actuator for moving the movable shade between a shading position and a shading relieving position. The movable shade is pivotally arranged so that it can be rotated round a rotary axis extending in a vehicle width direction, in a neighborhood of a lens center axis. A rod member has one end portion connected to the movable shade and the other end portion connected to the actuator. The actuator gives a drive force to the rod member in a longitudinal direction of the rod member.

摘要： A movable shade is moved by a shade driving device between a first shade position which is positioned on an optical axis at a rear focal point of a projection lens and a second shade position which is located further downward than the first shade position. Even in the event that there is provided only a single light source, low beam light distribution patterns and high beam light distribution patterns can selectively be formed. In addition, the light source is moved by a light source driving device between a first light source position which is positioned on the optical axis and a second light source position which is positioned further forward than the first light source position. Then, four types of light distribution patterns can be formed through combinations of the positions of the light source and the positions of the movable shade.

摘要： Optical axes are simultaneously adjusted when a plurality of lighting device units 30, the light sources of which are light emitting elements 34, are tiltably supported by the common unit support member 20. In this case, the positioning recess portion 20d is provided which is composed so that the light source fixing portion 20B1 formed in a plurality of portions of the unit support member 20 can be contacted with the back face 42a and the outer circumferential face 42b of the support plate 42 for supporting the light emitting element 34. Due to the foregoing, the light emitting element 34 can be highly accurately attached to the unit support member 20, and the optical axes Ax, of the lighting device units 30 can be put in order.
