A vehicle headlight can include a light source, first and second ellipse group reflecting surfaces having a focus corresponding to the light source, a first parabolic group reflecting surface with a focus on a second focus of the second ellipse group reflecting surface, and a second parabolic group reflecting surface with a focus corresponding to the position of the light source. A movable shutter can be provided with a shutter part and a shade part. When the shade part is placed in the light flux of the first ellipse group reflecting surface, the shade part shades the light flux irradiating from the light source to the second parabolic group reflecting surface. On the other hand, when the shutter part is withdrawn from the light flux, the second parabolic group reflecting surface can receive light. The second ellipse group reflecting surface can reflect unused light from the first ellipse group reflecting surface toward the first parabolic group reflecting surface, and the first parabolic group reflecting surface can reflect the light in the irradiation direction. Thus, the low-beam distribution and the high-beam distribution can be improved in illumination. Furthermore, the light from the second parabolic group reflecting surface that is to be projected in the front direction can be added to the light reflected from the first ellipse group reflecting surface to improve the visibility in the front of the vehicle during high-beam distribution.

A vehicle light can include a single light source and be capable of switching between low-beam mode and high-beam mode by moving a movable portion. The vehicle light can also include a first reflecting surface, a projection lens, and a shutter selectively insertable in the luminous flux from the first reflecting surface to the projection lens. The vehicle light can further include a second reflecting surface having a first focus and a second focus, a third reflecting surface having a first focus and second focus, a fourth reflecting surface having a focus approximately on the second focus of the second reflecting surface, wherein when the third reflecting surface is located in its inserted position relative to luminous flux between the second reflecting surface and the fourth reflecting surface, the first focus of the third reflecting surface is substantially on the second focus of the second reflecting surface. The movable portion can include the shutter and the third reflecting surface.

The actuator for leveling actuation indispensable to be provided for the head lamp for a vehicle having the discharge lamp 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.

An automobile headlight including a single movable light source which does not change the angle of its optical axis relative to the optical axis of the reflector. The light source is coupled to an apparatus capable of changing the position of the light source depending on the driving state of the automobile. The headlight has sufficient light distribution patterns for multiple driving conditions, such as when the automobile is traveling straight ahead, by-passing another vehicle, or carrying a heavy load, without changing the angle of the optical axis of the light source relative to the optical axis of the reflector. This allows the driver to maintain good visibility while prolonging the life of the headlight and reducing its overall size.
