Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicular lamp having two adjacent lamp chambers.

[0002]

2. Description of the Related Art A vehicular lamp such as a rear combination lamp has a plurality of lamp chambers, and a light source bulb is normally inserted into each of the lamp chambers from the rear side. I have. Such a light source bulb mounting structure is uniformly employed even when the amount of rearward projection differs between the adjacent lamp chambers 2 and 4 as shown in FIG.

[0003]

For this reason, in the above-mentioned conventional light source bulb mounting structure, the depth dimension of the entire lamp becomes large, and interference with the vehicle body side member is easily caused.
There is a problem.

[0004] In particular, since a lamp chamber formed so as to protrude backward from other lamp chambers generally has a large power, a light source bulb socket inserted into the lamp chamber is large. Therefore, there is a problem that the depth dimension of the entire lamp becomes larger by that much, and the interference with the vehicle body side member is more likely to occur.

The present invention has been made in view of such circumstances, and in a vehicle lamp in which one of two adjacent lamp chambers is formed to protrude rearward, an entire lamp is provided. It is an object of the present invention to provide a vehicular lamp capable of reducing the depth dimension.

[0006]

SUMMARY OF THE INVENTION The present invention achieves the above-mentioned object by devising a light source bulb in a mounting direction.

That is, the present invention comprises a first lamp chamber and a second lamp chamber formed adjacent to each other, wherein the first lamp chamber is provided with the first lamp chamber. In a vehicular lamp formed so as to protrude rearward from the two lamp chambers, the light source bulb is inserted into the first lamp chamber from the side of the second lamp chamber and the second lamp. The light source bulb is inserted into the chamber from the rear side.

[0008] The above-mentioned "first light room portion and second light room portion"
It may be formed vertically adjacent to each other,
It may be formed adjacent to the left and right direction.

[0009]

As described above, in the vehicle lamp according to the present invention, the light source bulb is inserted into the first lamp compartment protruding rearward from the second lamp compartment, and Since the light source bulb is inserted into the second lamp chamber from the rear side, the following operation and effect can be obtained.

That is, since the first lamp chamber protrudes rearward from the second lamp chamber, interference of the first lamp chamber with the vehicle body side member is provided on the second lamp chamber side of the first lamp chamber. A space (hereinafter, referred to as a “dead space”) is formed with respect to the light source bulb in the present invention. Since the lighting is performed from the lamp room side, it is possible to prevent the depth dimension of the entire lamp from increasing. The insertion of the light source bulb into the second lamp chamber is also performed using the dead space.

As described above, according to the present invention, in a vehicle lamp formed such that one of two adjacent lamp chambers protrudes rearward, the entire lamp is compared with a conventional vehicle lamp. Can be reduced in depth dimension. Thus, it is possible to effectively prevent the lamp from interfering with the vehicle body-side member.

Further, in the present invention, the sockets for the light source bulbs of the first lamp chamber and the second lamp chamber are arranged close to each other, so that the cords extending from these sockets are connected. Since the cords are less likely to be unnecessarily slackened, the work of attaching the light source bulb to each of the lamp chambers becomes easier.

In this case, as described in claim 2, the portion of the reflector constituting the first lamp chamber portion on the side of the second lamp chamber portion is formed in a standing wall shape extending substantially in the front-rear direction. Therefore, it is particularly effective to employ the above configuration, since a sufficient dead space can be secured on the side of the first lamp chamber on the side of the second lamp chamber.

When the reflector comprises an inner reflector disposed inside the lamp body, the first lamp chamber has a double structure and projects rearward. Employing the above arrangement is particularly effective because the volume is even greater.

Further, in the case where the reflecting surface of the reflector constituting the second lamp chamber is formed by forming a plurality of reflecting surface elements on a free-form surface, as described in claim 4, In addition, the second lamp chamber can be formed thin, and the dead space can be made larger. Therefore, it is particularly effective to adopt the above configuration.
