The present invention relates to an integrated light bulb in which one side of the back chamber is retracted to return laterally, and a plurality of light bulbs having different functions such as brake lights, direction lights, backward lights, and vehicle widths are formed of resin together with tail lights. The present invention relates to an improvement in a so-called combination-type automobile tail light that is partitioned and accommodated in the main body, and more particularly, to an automobile tail light having an excellent appearance design as well as improving the mountability to the vehicle body by miniaturizing and reducing the light bulb body.

Background Art [0002] Conventionally, reflector bulbs in which a plurality of lamps having different functions are divided and housed in an integrated bulb body called a combination lamp have been used as a vehicle lamp, and constitute a rear part design of an automobile.

However, in this kind of combination type taillight for automobiles, as shown in FIG. 18, the lamp body 50 is divided into a plurality of lamp chambers 53 by ribs 51, and each lamp A reflector 55 having a parabolic reflecting surface is mounted behind the lighting bulb 54 provided in the chamber 53 to provide a structure in which a front reflecting light beam having a predetermined brightness is obtained as a light bulb.

In such taillights for automobiles, portions 55a protruding forward than the front lens 56 to the reflecting edges (arrows A) of the reflector 55 to obtain the reflected light flux having a predetermined brightness (see the dashed-dotted line). Because of this, the entire reflecting mirror 55 must be retracted to increase the depth dimension X of the light bulb body 50 as well as increase the size of the light bulb body 50 as a whole.

That is, in the structure of the conventional combination taillight for automobiles, since the protrusion X in the vehicle body, such as a trunk room, becomes large, the vehicle body fixing ability is bad, and not only the shape change of the vehicle body or the design of the lamp fixture attachment side of the vehicle body is forced, In general, since the front projection 55a of the reflector 55 formed in the back chamber 53 is cut at the position retracted from the front lens 56, it becomes a structure composed of the non-parabolic surface portion 56b. The emitted light beam of 54) only brightens this corner portion A, so that, as with other portions, it does not become the reflected light beam toward the front of the front lens 56, and the corner portion A becomes darker than the center portion. Had a problem to do.

In addition, as a structure in which the front lens 56 is turned sideways (arrow B), it is not possible to form an effective reflector 55, and this problem also has a problem that dark parts are generated.

The present invention has been made in view of the above problems, and in a so-called automobile tail light having a portion that has been turned to the side, the bulb body is made compact or thin, which improves the mountability and design of the vehicle body, and is divided into an integral bulb body. The present invention provides an automobile taillight that eliminates the dark portion at the time of lighting each of the received bulbs.

In order to achieve the above object, the taillight for automobiles according to the present invention is a combination type lamp, which has a structure in which a side of the back chamber is retracted to return to the side and covered from the front to the side by a front lens, Each of the lamp chambers arranged in the lamp body constituting the lamp is partitioned into a long vertical or long rectangular shape, and at least one of the vertically long lamp chambers in each of the lamp chambers is a taillight brake lamp. Or it consists of a chamber, such as a combination of two functions such as taillights and direction indicator lights, and the upper angular corner or upper and lower angular corner formed at the diagonal position in the chamber as a back wall showing the step shape will be.

The front surface of the stepped rear wall portion of the back chamber may be formed of a reflector integrated with the other rear wall, and may be partitioned so as to be inclined to the upper side when the respective back chambers are viewed from the front.

A light shielding film strip is formed on the rear surface of the front lens covering the vertically long back chamber formed in a large size so that the front lens can be seen as an equal chamber in which the front lens is equally partitioned from the front side by matching the arrangement direction with the partition wall of the lamp body. Thus, the front design of the front lens can be unified.

The partition wall formed by partitioning the back chamber is composed of double ribs arranged side by side with a deep groove wall and a shallow groove wall, and includes a rib provided linearly on the rear surface of the front lens covering the front surface of the main body and the light shielding along both sides of the rib. It is fitted through the member.

According to the taillight for automobiles of the above-described structure, the structure of the staircase wall portion allows not only the projection of the reflector in the back chamber to be relatively short in depth, but also the reflector configured in the staircase wall portion. As a result, the reflected light beam having a predetermined luminance with respect to the front of the front lens can be ensured, and the light bulb can be miniaturized.

In addition, since the front lens is configured to fit between the deep groove wall and the shallow groove wall in contact with both sides of the rib along the light shielding member, the groove width between the deep groove wall and the shallow groove wall is relatively wide and the height of both groove walls is also increased. By changing the shape, the demolding of this part becomes easier and the moldability of the bulb body becomes good.
