DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described in detail based on an embodiment shown in the drawings. FIG. 1 shows a first embodiment of the present invention. In the drawing, reference numeral 10 denotes a variable light distribution headlamp according to the present invention. The variable light distribution headlamp 10 has a light source 2 such as an incandescent light bulb attached to a predetermined position of a reflecting mirror 1, and the reflecting mirror 1 has a parabolic reflecting surface or a free-form surface.

At the position of the light source 2, the light source 2 is supported by a rotating shaft 3 in a vertical direction in a state where the light source 2 is mounted on a vehicle body. The rotating shaft 3 is linked to a steering device (not shown) such as a steering shaft, and moves the irradiation axis X in the turning direction of the vehicle as the driver operates the steering wheel. .

Then, on the side of the front surface of the reflecting mirror 1,
In order to improve the appearance when mounted on a vehicle, a housing and an extension 4 are provided.
And the vehicle body. Further, an outer lens 5 is provided in front of this, and seals the variable light distribution headlamp 10. The above configuration is the same as that of the conventional example.

Here, in the first embodiment of the present invention, a standing wall 6 is provided at the end of the reflecting mirror 1 in the horizontal direction. The standing wall 6 will be described in detail. A flat plate having substantially the same width as the thickness of the reflecting mirror 1 in the vertical direction is provided at both ends in the horizontal direction of the reflecting mirror 1 so as to extend from the front end to the rear end of the reflecting mirror 1. Or it consists of a curved plate. The standing wall 6 may be formed integrally with the reflecting mirror 1, or a separate member may be attached later as in the first embodiment.

Although the steps are omitted when the standing wall 6 is made of the same material as that of the reflecting mirror 1, it is naturally possible to use a completely different material. The outside of the standing wall 6 is subjected to the same reflection processing as the inside of the reflecting mirror 1, and the rear end is curved outward as necessary.

According to the above arrangement, when the vehicle approaches a curved road that requires a right turn, for example, the steering device is operated, and the reflecting mirror 1 also rotates rightward by an angle corresponding to the operation amount of the steering device. The irradiation axis X is directed in a predetermined direction. At this time, one end of the reflecting mirror 1 projects toward the extension 4 due to the rotation of the reflecting mirror 1, but in the first embodiment, since the standing wall 6 is formed at this position, The rear surface of the reflecting mirror 1 is not viewed as in the conventional example.

Further, the outside of the standing wall 6 is subjected to a reflection treatment or the like, and is made to be the same as the reflection surface of the reflection mirror 1, so that the appearance is excellent. In addition, although the example in which the reflection processing was performed on the outside of the standing wall 6 has been described,
When a housing or a body is located instead of the extension 4, the colors may be the same as those colors.

FIG. 2 shows a variable light distribution headlamp 10 according to a second embodiment of the present invention. In this second embodiment as well, a reflecting mirror 1 which rotates according to the operation amount of a steering device is provided. This is the same as the first embodiment described above, and the same is the point that the standing wall 6 is provided at the end of the reflecting mirror 1, but in the second embodiment, , And a rib 7 are provided.

The rib 7 is formed of a curved plate having a width greater than the vertical thickness of the reflector 1, and is arranged so as to mainly cover the horizontal side surface of the reflector 1. The attachment of the rib 7 is performed on the extension 4 and a housing or a body (not shown). The ribs 7 may be formed integrally with the extension 4, a housing or a body (not shown).

The rib 7 is knurled or the like to operate a steering device to drive the variable light distribution headlamp 10 to rotate the reflecting mirror 1 and emit light from the light source 2. A process for preventing glare light due to reflection of light on the ribs 7 may be performed. The first purpose of the rib 7 is to move the variable light distribution headlamp 10 so that the reflecting mirror 1 rotates,
Since the rib 7 is provided for the purpose of preventing the inside of the variable light distribution headlamp 10 from being viewed, the rib 7 is simply made the same color as the housing or the body, and the rib 7 is viewed. It is also good that there is no discomfort.

As described above, according to the second embodiment, the rib 7 is formed even when the variable light distribution headlamp 10 is driven and the reflecting mirror 1 is rotated to form a gap. In addition, the interior of the variable light distribution headlamp 10 and other lamps connected to the variable light distribution headlamp are not visually observed, and the appearance is excellent. In addition, if the rib 7 is appropriately knurled, it is possible to prevent the variable light distribution headlamp 10 from generating glare light.

[0019]

According to the present invention, the variable light distribution headlamp 10 is provided.
With the above configuration, even when the reflecting mirror 1 is rotated by the driving of the variable light distribution headlamp 10, the standing wall 6 can be viewed without the rear surface of the reflecting mirror 1 being viewed. By making the standing wall 6 have the same reflection treatment and color as those of the extension 4, the housing and the body, the variable light distribution headlamp 10 can provide a sense of unity with the vehicle body even when the reflecting mirror 1 rotates. You will have it, and it will be excellent in aesthetics.

Further, by providing the ribs 7, even if the reflecting mirror 1 is rotated by driving the variable light distribution headlamp 10 and an interval is formed between the reflecting mirror 1 and the extension 4, the ribs 7 can be viewed. Therefore, the inside of the variable light distribution headlamp 10 and other lamps adjacent to the variable light distribution headlamp 10 are not viewed, and the appearance of the variable light distribution headlamp 10 is deteriorated by driving the variable light distribution headlamp 10. There is no.
Further, if a predetermined knurl cut or the like is applied to the rib 7, glare light is not generated, and harmony with other lamps can be obtained, so that a sense of unity can be obtained.
