Secondly, the presence of the vehicle body lamp light source 95 in the plane of the headlight reflector 93 causes the vehicle body lamp light source 95 to be seen through the lens 91 and impair the aesthetic appearance. At the same time, since the opening 93a is set to have a diameter sufficiently larger than the outer diameter of the light source 95 for the vehicle width lamp, the socket 95a of the light source 95 for the vehicle width light can be seen from the gap, making it even more unsightly. Some problems have arisen.

Thirdly, since the light source light 95 for the vehicle side lamp is directly seen through the lens 91, the light source 9
When the lamp 5 is turned on, only the part of the light source 95 for the vehicle side lamp looks bright and shining, and the light emitting area becomes narrow, and the light distribution characteristics as the vehicle side lamp also become insufficient. The solution of this point is an issue.

[0007]

According to the present invention, as a specific means for solving the above-mentioned conventional problems, a headlight light source and a vehicle body light source are provided in an integrated lamp body. The headlamp light source is provided at a position outside and forward of the headlamp reflector and at the back of the extension. The problem is solved by providing a vehicle headlight / headlight which is provided with a vehicle body light reflector that reflects light from a lamp light source toward the headlight reflector. Things.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described in detail based on an embodiment shown in the drawings. 1 and FIG.
The vehicle headlamp / headlamp 1 according to the present invention includes a headlamp light source 4 and a vehicle headlamp in a lamp body formed by a lens 2 and a housing 3. The point that the light source 5 for the lamp is provided is the same as that of the conventional example.

In addition, a movable headlight reflecting mirror 6 is provided in the lamp body so that the irradiation direction as a headlight can be adjusted, and the headlight light source 4 is a headlight reflecting mirror. 6 and is configured to move together with the headlight reflecting mirror 6, and further provided with an extension 7 for covering the gap between the headlight reflecting mirror 6 and the housing 3. This point is the same as the conventional example.

Here, in the present invention, the vehicle width light source 5 is provided at a position outside the front of the headlight reflecting mirror 6 and at the back of the extension 7.
In addition, the vehicle body lamp light source 5 has a vehicle body lamp reflector 8 that reflects light from the vehicle body lamp light source 5 toward the headlight reflector 6 so as to form a rear surface of the extension 7. It is provided in.

The light source 5 and the reflector 8 are installed on the lamp body composed of the lens 2 and the housing 3 in the same manner as the extension 7, so that the headlight reflector is provided. Even during the movable operation for adjusting the irradiation direction of 6, the mutual position of the extension 7, the light source 5 for the vehicle body lamp, and the reflecting mirror 8 for the vehicle body lamp does not change.

Next, the operation and effect of the headlamp 1 having the above-described structure according to the present invention will be described. First, when the vehicle body lamp light source 5 is turned on under the condition that the vehicle body lamp needs to be turned on, such as at twilight, the direct light from the vehicle body lamp light source 5 and the reflected light by the vehicle body lamp reflecting mirror 8 become: The light passes through the gap D between the extension 7 and the headlight reflector 6, and reaches the reflection surface of the headlight reflector 6.

At this time, if the size of the gap D and the shape of the vehicle body lamp reflecting mirror 8 are appropriately set, the light from the vehicle body lamp light source 5 will be substantially the same as that of the headlight reflecting mirror 6. The entire surface of the headlight reflecting mirror 6 becomes brilliant, and the function as a vehicle width light is performed in a wide area.

Therefore, according to the present invention, the headlight reflecting mirror 6 is provided.
Can be used as a vehicle width light without providing an opening in the headlight, and when used as a headlight, the effective area of the headlight reflector 6 is not reduced, or the shape of the headlight reflector 6 is not deformed by the opening. It is possible to avoid the influence on the illuminance characteristics and the light distribution characteristics as a headlight.

Further, with the above-described structure, the vehicle side light source 5 is covered with the extension 7 and cannot be directly seen from the front of the vehicle side lamp / headlamp 1, so that the lens 2 can be seen through. Thus, it is possible to avoid the point that the light source 5 for the vehicle side lamp and the socket attached to the light source 5 and the like are visually impaired.

Further, as described above, since the vehicle side light source 5 is provided at a position where it cannot be seen directly, the direct light from the vehicle side light source 5 having high brightness is covered and directly viewed by the viewer. And the light reaching the observer is of a relatively uniform brightness that is once reflected by the headlight reflecting mirror 6, thereby improving the light distribution characteristics as a vehicle lamp. Become.

[0017]

As described above, according to the present invention, the light source for the vehicle width lamp is provided at a position outside and forward of the headlight reflector and at the back of the extension. The light from the light source for the vehicle headlight is a vehicle headlight combined headlight provided with a vehicle width light reflecting mirror that reflects the light toward the headlight reflecting mirror. The function as a vehicle width light can be performed without providing an opening in the headlight reflector, and this will not reduce the effective area of the headlight reflector and will not cause deformation of the shape due to the opening. Thus, the present invention has an extremely excellent effect of realizing a headlight that is also used as a vehicle width light without reducing the illuminance and the light distribution characteristics of the headlight.

Second, the vehicle width is set at a position outside the front headlight reflector and behind the extension without providing an opening in the headlight reflector as described above. With the configuration in which the light source for the lamp is provided, the light source for the vehicle width lamp is concealed by the extension, and the light source for the vehicle width lamp and the light source for the light source for the vehicle width lamp are arranged in the plane of the headlight reflecting mirror as in the conventional example. A socket or the like is provided so that they are not viewed through the lens, and an excellent effect is also provided for improving the aesthetic appearance of the vehicle headlamp and headlamp.

Third, by concealing the light source for the vehicle width lamp on the back of the extension, the light reaching the viewer has a substantially uniform brightness reflected by the reflector for the headlight. This eliminates the formation of extremely bright areas in some areas, and almost the entire headlight reflector functions as a vehicle width light, improving the light distribution characteristics as a vehicle width light, such as an expanded display area. As a result, an extremely excellent effect on performance improvement can be obtained.
