Description

[Detailed description of the device] [Industrial applications]

The present invention relates to an auxiliary braking light that is attached to an automobile or the like and is commonly called a high mount stop lamp, and more particularly to a vehicular lamp that is attached to a rear windshield of a vehicle interior.

[Prior art]

As a conventional vehicle lamp of this type, for example, Japanese Patent Laid-Open No. 62-62
-94440, there is a substrate shown in FIG. 1 in which a plurality of light emitting diodes are mounted in a rear opening of a rectangular frame-shaped housing (first lamp body) having a lens attached to a front opening. Is screwed and fixed, and further, a back cover (second lamp body) is screwed and fixed so as to cover the substrate from the rear side.

[Problems to be solved by the device]

However, the above-described conventional vehicle lamp requires a mounting member such as a screw when mounting the substrate and the back cover to the housing (first lamp body), and the assembly for this mounting member is required. This requires a process, and therefore, particularly in a vehicle lamp that is long in the width direction and strongly demanded from the recent market, the number of the above-mentioned mounting members will inevitably increase. The number of parts and the assembling process are increased, which makes it difficult to reduce the cost and loses the marketability. In addition, the above-mentioned complicated assembly is complicated at the same time in terms of maintenance such as replacement of the substrate at the time of failure, and there is also a problem of lack of serviceability. In addition, there are various sizes of automobiles equipped with this type of lamp, such as large size and small size, and in order to adapt to them, special molds are used for the housing including the lens, the back cover, etc. There is no choice but to create it, and this also raises the cost and loses the marketability, and the solution of these points has been an issue.

[Means for Solving the Problems]

The present invention, as a specific means for solving the above-mentioned conventional problems, has a substantially U-shaped cross section with front and left and right ends open, and fitting grooves are formed in the upper and lower inner walls across the left and right end openings. A housing part formed by means of the above, a lens part mounted so as to close the front opening of the housing part, and a substrate mounted with a light source that is slid into the fitting groove from the end opening of the housing part. And a cap that is engaged with each of the end openings in a lid shape, thereby reducing the number of parts and the number of assembling steps and further reducing the number of parts. A lamp having a width can be simply manufactured to solve the conventional problems described above.

【Example】

Next, the present invention will be described in detail based on an embodiment shown in the drawings. Reference numeral 1 in FIG. 1 is a vehicular lamp according to the present invention. The housing part 2 of the vehicular lamp 1 is made of an opaque member such as a resin and has a cross section in which front and left and right ends are open. It comprises a substantially U-shaped housing portion 2b and a lens portion 2a which is also made of a transparent material such as resin and is attached so as to close the front opening portion of the housing portion 2b. Is the end opening 2d at both ends
In addition, the housing portion 2b is provided with a fitting groove 2c formed by a pair of guide ribs formed upright on each of the inner surfaces of the upper and lower walls over the end opening 2d. . With the above configuration, the cross section of the housing portion 2 in the vertical direction has the same shape at any place. Therefore, when forming the housing 2, for example, the lens portion 2a and the housing portion 2b are It may be integrally molded by color extrusion molding, or the lens portion 2a and the housing portion 2b may be separately formed by the same means and integrally formed by an appropriate means such as adhesion or fitting. . In addition, since it can be molded by the above-mentioned extrusion molding,
By preliminarily forming an extremely long channel shape and cutting it into an appropriate length, the housing 2 having a desired width direction dimension can be freely obtained. Reference numeral 3 in the figure indicates a printed wiring circuit formed by L
It is a substrate on which a plurality of ED elements 3a are mounted, and is placed at a predetermined position of the housing 2 by a step of simply inserting the ED element 3a into the fitting groove 2c from either side of the end opening 2d of the housing 2. It will be installed. After the substrate 3 is mounted, the housing 2 is fitted with a cap 4a that engages with the end opening 2d in a lid shape, and the substrate 3 is detached from the housing 2 by the cap 4a. Will be prevented. The cap 4a is attached as a mounting leg portion 4 including a suction plate 4b with an L-shaped member 4c which is attached in advance. At this time, the end portion of the L-shaped member 4c on the cap side is the second. As shown in the figure, for example, the spring washer 5 and the nut 6 are attached so as to form a rotating shaft, that is, a hinge portion of a conventional example. FIG. 3 shows a usage state of the vehicular lamp 1 of the present invention as described above. The suction window 4b is used for the rear window 11 in FIG.
By attaching it to the vehicle, and then rotating the housing part 2 so that the irradiation direction is directed to a predetermined direction in order to compensate for the difference in the inclination angle of the rear window 11 for each vehicle type and the like. The mounting of the lamp 1 is completed. Although not shown, for example, the rotary shaft may be held in place by tightening a screw instead of the one holding the position by the friction of the spring washer 5 of this embodiment. It goes without saying that the gist of the invention is not impaired, and the same applies to other appropriate changes such as the use of a double-sided adhesive tape or the like instead of the suction plate 4b.

[Effect of device]

As described above, according to the present invention, the fitting grooves are provided in the inner surfaces of the upper and lower walls of the substantially U-shaped housing portion of the housing portion over the end openings, and the fitting grooves are provided with The structure of the vehicular lamp that mounts the board at a predetermined position in the housing by sliding the board into place makes it possible to mount the board with a simple structure without the need for a locking member as in the conventional example. The number of parts and man-hours can be reduced, and an excellent effect of cost reduction can be achieved. In addition, the fact that the substrate can be attached and detached with a simple configuration simplifies the handling of problems in the market later and improves maintenance and serviceability. Further, with the above configuration, the housing portion can be formed by a simple molding means such as extrusion molding, and from this aspect, an excellent effect of cost reduction can be obtained. In addition, since it can be molded by the extrusion molding, the housing portion is previously formed in a long channel shape, and it is simply cut out to an appropriate size from this, for example, for a large vehicle, a small vehicle, or the like. A vehicle lamp having a width can be freely obtained without any additional mold cost, and also has an excellent effect of giving a wide range of adaptability to products.
