摘要： A conventional projector headlamp has low efficiency because an amount of light is shaded almost half by a shutter for a low-beam light distribution. In addition, only a projection lens is seen in the installed condition, inviting old-fashioned designs disadvantageously. In a projector headlamp (1) of the invention, a vertical section passing through the center of a projection lens (5) includes a convex front surface and a flat rear surface (5a). A line connecting the upper end to the lower end on the rear surface (5a) is tilted to the vertical. Thus, the projection lens (5) has a prismatic action for directing the entire light downward. This is effective to reduce an amount of light to be shaded by a shutter (4) and provide improved brightness and novel designed appearances.

摘要： 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 On the other hand, when the shutter part is withdrawn from the light flux, the second parabolic group reflecting surface can receive light.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.

摘要： A projector type lamp can include a projection lens formed by combining together projection lens elements obtained by processing a plurality of projection lenses that can be substantially identical in optical axis center Z, focal length, and focal point, yet different in outer diameter. The projection lens can appear substantially rectangular when viewed in an optical axis direction. Boundary portions between the plurality of processed projection lens elements can be composed of a line connecting points of intersection between a contour line of the projection lens and a line defining a part of each unprocessed projection lens element at which thickness is substantially zero. The lens surfaces of the processed projection lens elements can be continuous with one another through stepped portions that are parallel to the optical axis of the projection lens.

摘要： 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.

The power limiting device can lower operational electrical power after a certain time interval has passed following initial application of operational electrical power to the switching device. The switching device can include an electromagnetic solenoid 5a with a coil. Sufficient electrical current can be applied to the switching device for an initial period when electromagnetic solenoid 5a requires comparatively high operational electrical power, and an electrical power limiting device can lower the electrical power applied to the switching device after a short time period. The size and cost of the switching device can be reduced, overheating can be avoided, and the longevity and reliability of the device can be increased.

摘要： A head lamp for a vehicle wherein an actuator is made to be able to be moved to a leveling actuation range 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 is moved to the beam change position B at least a part covering a lower half of a discharge lamp of the hood is moved back to switch it from a passing beam state to a drive beam state. 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.

摘要： A headlight exclusively for irradiating as light beam for a vehicle passing by in the opposite direction includes a light source and a reflective mirror as essential components. The reflective mirror has a first reflective surface having a contour of a revolving parabolic plane on an upper half of the reflective mirror, a second reflective surface having a contour of a revolving parabolic plane arranged at the central part of a lower half of the reflective mirror, and two reflective surfaces each having a contour a cylindrical parabolic plane arranged on the opposite side of the second reflective surface on the lower half of the reflective mirror. The last-mentioned reflective surfaces comprise a first surface and a second surface. The first surface serves to allow the light beam to be converged in the shape a substantially parallel light beam as seen in one direction, and the second surface serves in the same manner as the first surface in another direction at a right angle relative to the former. The headlight may be designed in the upside-down relationship relative to the aforementioned headlight such that all or the essential components are arranged upside down.
