Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to an automotive lamp having a plurality of lamp chambers and performing a plurality of functions, such as an automotive rear combination lamp.

<Prior art> Automotive lamps that have multiple light chambers and have multiple functions, such as rear combination lamps for automobiles, have a certain light chamber function as a destination (export destination).
Depending on the specifications (standards), there are cases where it is necessary and cases where it is not necessary.

In such a case, it would be costly to manufacture and assemble each component according to the specifications of the destination.
Conventionally, as shown in FIG. 9, when the function of a certain lamp chamber a'is not required, the lamp chamber a'is left as it is without installing a bulb or a reflecting mirror. Therefore, when viewed through the front lens 2 when the lamp is not lit, the lamp chamber a ′ becomes a dark part, and the lamp wall 6 forming the lamp chamber a ′ needs the lamp chamber a ′. Since the light-blocking rib 7 is extended near the front lens 2 in preparation for the case, the light-blocking rib 7 further emphasizes the difference in brightness between the lamp chamber a ′ and the surrounding lamp chamber b ′. As a result, there was a problem that the appearance of the entire lamp was impaired. On the other hand, if dummy coating is applied to the inner surface of the front lens 2 corresponding to the lamp chamber a ′, there is a problem that the sense of unity with the surrounding lamp chamber b ′ is lost.

<Problems to be Solved by the Invention> The present invention has been made in view of such a conventional problem, and there is a case where the function of a certain lamp chamber is required in some cases and a case where it is not necessary in some cases. In addition, it is not necessary to manufacture and assemble each component according to the specifications of the destination, and of course, when the function of a certain light room is not needed, the dark part in the light room is eliminated and the surrounding light room is It is possible to improve the sense of unity of automobiles, and when the function of the lamp room is required, we will not provide a high-commercial-value lamp for automobiles that is not likely to leak light from the lamp room to surrounding lamp rooms. It is what

<Means for Solving the Problems> The vehicle lighting device of the present invention which achieves such an object has a plurality of lamp chambers, and a case where the function of a certain lamp chamber in the lamp chamber is required or not required in terms of specifications. In automotive lighting with
When the function of the lamp room is required, an extension rib is installed on the light shielding rib of the lamp wall that constitutes the lamp room, and when the function of the lamp room is not required, The feature is that a cover covering the entire surface is installed in the front opening.

<Embodiment> An embodiment of the present invention will be described below with reference to the drawings.

A lamp A of the illustrated embodiment is an automotive rear combination lamp having the functions of a fog lamp a, a backup lamp b, a turn signal lamp c, and a tail / stop lamp d, and one or a plurality of lamp bodies (lamps) as in the conventional case. Body) 1 and one or a plurality of front lenses 2 partition the lamp chambers 3a, 3b, 3c, 3d of the respective lamps a to d, and the bulbs 4a, 4b, 4c, 3d are formed in the respective lamp chambers 3a to 3d. 4d and reflectors 5a, 5b, 5c, 5
It is configured so that d, is installed to exert the function of each of the lamps a to d. In the figure, e is a reflex reflector.

Of the above-mentioned lamps (functions) a to d, the fog lamp a is a function that is required for domestic and European purposes but not for the United States in accordance with the specifications, and the function of the fog lamp a is required (see FIG. 1 to FIG. 1). In the case where the function of the fog lamp a is not required (see FIG. 3), the extension rib 8 is integrally attached to the light shielding rib 7 of the lamp wall 6 forming the lamp chamber 3a of the fog lamp a (see FIG. 3). 4 to 6), a cover plate 10 that covers the entire surface of the fog lamp a is installed in the front opening 9 of the lamp chamber 3a.

That is, when the light-blocking rib 7 of the lamp wall 6 forming the lamp chamber 3a of the fog lamp a is formed in advance to be short and the function of the fog lamp a is required for domestic and European purposes, FIG. As shown in FIG. 3, the bulb 4a and the reflecting mirror 5a are installed in the lamp chamber 3a of the fog lamp a, and the extension rib 8 is integrally attached to the light shielding rib 7 of the lamp wall 6. This extension rib 8 is similar to the light shielding rib 7 in the lamp chamber 3a.
Is formed in a ring shape surrounding the front opening 9 of the light shielding rib 7 and at least the inner surface thereof is attached to the light shielding rib 7
The inner surface is flush with the inner surface, and the tip edge 8a is formed so as to be close to the inner surface of the front lens 2, and is integrally formed on the tip portion of the light shielding rib 7 by appropriate engaging means or adhesion or welding. Install.

When the function of the fog lamp a is not needed in the United States, as shown in FIGS. 4 to 6, the bulb and the reflecting mirror are not installed in the lamp chamber 3a, and the bulb installation hole 11 is provided. The blind cover 12 is airtightly closed or the bulb installation hole 11 is left unopened from the beginning, and a cover plate 10 covering the entire surface is installed in the front opening 9 of the lamp chamber 3a. The cover plate 10 is formed in a flat plate shape having a size that covers the entire front opening 9 of the lamp chamber 3a including the light shielding rib 7 of the lamp wall 6 that constitutes the lamp chamber 3a, and has an inner peripheral edge. A mounting rib 10a is formed so as to project, and is bonded or welded to the lamp wall 6 or the light shielding rib 7 via the mounting rib 10a.

For the tail & stop lamp d, a double filament bulb is usually used and its main filament is arranged at the focal position of the reflecting mirror to exert the function of the stop lamp, and the sub filament is arranged above the focal position of the reflecting mirror. Although it is configured to exert the function of the tail lamp, the light distribution of the tail lamp is particularly downward because the light source (subfilament) is located above the focal point of the reflecting mirror, and the visibility is poor. There was a problem. Therefore, in the tail & stop lamp d according to the present invention,
As shown in the figure, the upper part 51d of the reflector 5d is tilted slightly rearward from the conventional one (shown by the chain double-dashed line), and
The main filament 41d of the above is arranged near the focal position of the reflecting mirror 5d so as to exhibit the function of the stop lamp, and the sub filament 42d is arranged above the focal position of the reflecting mirror 5d so as to exhibit the function of the tail lamp. It is composed. By configuring the tail & stop lamp d in this way, the light distribution P ₁ of the stop lamp will also be slightly upward, but the light distribution P _{2 of the} tail lamp will be more upward than in the past and satisfy the standard of the light distribution pattern. As a result, the visibility of the tail lamp can be improved.

Further, when the reflecting mirror 5d is fixed inside the lamp body 1, as shown in FIG. 7, a concave portion matching the heat-resistant protector 13 is formed on the surface of the lamp body 1.
If the heat-resistant protector 13 is housed and installed in the recess 14 in a flush manner and the heat-resistant protector 13 is integrally fixed to the lamp body 1 together with the reflecting mirror 5d with the rivet 15 or the like, the parts 13, 5d are formed. It is possible to reduce the number of assembling steps and improve the assembling workability, and at the same time, it becomes advantageous to secure the installation space.

When mounting the lamp A on the vehicle body B, as shown in FIG. 8, a mounting bolt 16 is integrally projected on the rear side of the lamp body 1, and the mounting bolt 16 penetrates into the mounting hole 17 of the vehicle body B. At the same time, a damper rubber 18 is installed between the lamp A and the vehicle body B and fastened with a nut 19. At this time, the damper rubber 18 is formed so that the lower surface of the stay 20 of the mounting bolt 16 is also elastically contacted with the damper rubber 18 by forming an insertion hole 21 through which the mounting bolt 16 penetrates.
Is easy to position and the risk of accidental peeling is eliminated, and the lamp A can be more firmly attached to the vehicle body B.

<Effects of the Invention> Since the automotive lighting device of the present invention is configured in this way, when the function of a certain light room is required in some cases or not in some cases, each configuration of the lamp body, front lens, etc. Since it is not necessary to manufacture and assemble parts according to the specifications of the destination, it is possible to reduce costs.

Moreover, when the function of a certain lamp room is not required, the presence of the cover plate that covers the entire front opening of the lamp room eliminates the occurrence of a dark part in the lamp room, and eliminates the problem of the surrounding lamp room (lamp). When the sense of unity can be improved and the function of a certain lamp room is required, the presence of the extension rib attached to the light shielding rib of the lamp room allows light to be emitted from the lamp room to the surrounding lamp rooms. There is no fear of leaking out, and it will be of high commercial value as a whole.

Therefore, the intended purpose can be achieved.
