摘要： A vehicle headlight (1) mounted on a vehicle body which can lean to one side at the time of turning around, i.e., going around a curve, moving circularly, or the like. The headlight includes a first ellipse group reflecting surface (4, 7) having a movable part (7a) and an opening part (7c), and a second ellipse group reflecting surface (6) corresponding to an area covering a moving range of the opening part. The movable part of the first ellipse group reflecting surface can be moved by a drive unit (8) to form a main light distribution kept always in a horizontal position. Light rays passing through the opening part (7c) reach the second ellipse group reflecting surface (6) to be reflected and to illuminate an area ahead of the vehicle body when it leans to one side.

摘要： A vehicle headlight (1) has a light source (2), first and second ellipse group reflecting surfaces (3,6) having a focus (f1) corresponding to the light source (2), a first parabolic group reflecting surface (7) with a focus on a second focus (f3) of the second ellipse group reflecting surface (6), and a second parabolic group reflecting surface (8) with a focus corresponding to the position of the light source (2). The movable shutter (4) has a shutter part (4a) and a shade part (4b). When the shutter part (4a) is placed in the light flux of the first ellipse group reflecting surface (3), the shade part (4b) shades the light flux reaching from the light source (2) to the second parabolic group reflecting surface (8). On the other hand, when the shutter part (4a) is withdrawn from the light flux, the second parabolic group reflecting surface (8) is allowed to receive light. Thus, the low-beam distribution and the high-beam distribution can be improved in illumination.

摘要： A head lamp (1) for a vehicle wherein an actuator (4) is made to be able to be moved to a leveling actuation range (A) corresponding to output from a vehicle body sensor and to a beam change position B out of a leveling actuation range when a beam changing switch is set to a drive beam position, and if the actuator (4) is moved to the beam change position B at least a part (5b) covering a lower half of a discharge lamp (2) of the hood (5) is moved back to switch it from a passing beam state to a drive beam state. The actuator (4) for leveling actuation indispensable to be provided for the head lamp for a vehicle having the discharge lamp (2) as a light source, makes it possible also to switch between the passing beam state and drive beam state, thereby dissolving problems of large size and high cost of the head lamp.
