Description

[Detailed description of the invention] Industrial application field This invention relates to a vehicle lamp, and is particularly compact because it has two directions of illumination and can be used to display both the front and rear directions of the vehicle. This invention relates to a double-sided light emitting type vehicle lamp used as a direction indicator light for a vehicle.

〓Prior art〓 Conventionally, the structure of this kind of double-sided emitting type vehicle lamp is as shown in Fig. 5, in which a light bulb socket 22 is attached to a base 21 made of metal die-casting such as aluminum, and a light bulb 23 is attached. , the light bulb 23
A lens 24 formed in a box shape of resin or the like so as to cover the lamp is screwed on with a lens mounting screw 26, and at this time, the two directions indicated by arrows A and B in the figure are the irradiation directions of this lamp. However, due to reasons such as the direction in which the mold is removed during molding,
Since it is difficult to cut lenses on the surfaces corresponding to the irradiation direction mentioned above in step 4, separately formed inner lenses 25 are attached to each surface by an appropriate method such as gluing to achieve the light distribution specified in the standards. It is something that acquires characteristics.

<Problems to be solved by the invention> However, in the conventional structure described above, it is inevitable that the base 21 in particular has a thick wall.
Even if it were planned to use resin for the purpose of weight reduction or cost reduction, it would result in appearance defects called sink marks, making it impossible to implement, and the shape cannot be formed by anything other than metal die-casting, and for this reason. This type of double-sided light emitting type lamp is heavy and expensive, which poses a major problem in practical use.

〓Means for solving the problems〓 The present invention has the following specific means for solving the problems that occur in the conventional double-sided light emitting type lighting device.
In a double-sided lighting device for a vehicle, which is an integrated lighting device such as the front and rear of a vehicle and is formed so that the light emitting directions are substantially opposite to each other on one side and on the other side, the base of the light device is divided into two parts perpendicular to the irradiation direction, and has a pair of substantially box-like shapes with a thin, uniform wall thickness and a notch, and a light bulb for attaching a light bulb and a light bulb socket to this base. A socket support plate provided with a socket support part and a base mounting boss for fixing the base is fitted in the shape of a partition plate and screwed into one piece, and a lens is fitted into the notch of the base and screwed. By providing a double-sided light-emitting type vehicle lamp characterized by a double-sided structure, it is possible to use resin, and the above-mentioned conventional problems can be solved.

〓Example〓 Next, the present invention will be explained in detail based on an example shown in the drawings.

What is designated by the reference numeral 1A in FIG. 1 is a resin base according to the present invention, which is divided into two parts at approximately right angles to the irradiation direction of this type of double-sided light emitting type lamp described in the conventional example. Note that the figure shows only one base 1A to avoid unnecessarily complicating it, but the other base 1B is approximately symmetrical to the illustrated base 1A, and cannot be butted against it. This is used to form the desired shape of the base.

The base 1A is formed into a thin, substantially box-like shape with uniform wall thickness so as to be suitable for resin molding, and is provided with a notch 1a in a portion into which the lens 3A is fitted, and is further parallel to the irradiation direction of the notch 1a. A slot 1b is provided by providing two band-like projections along the sides, and a base mounting hole 1c is provided on the side surface of the base 1A, that is, on the box-shaped bottom surface.

Here, the difference between this base 1A and the other base 1B, which is not shown, will be explained.
The base 1A is provided with a cylindrical lens mounting boss 1d on the tip side so as to protrude in both directions parallel to the irradiation direction of this lamp described above, but this is omitted on the other base 1B. .

Next, the socket support plate 2 is attached to the bases 1A, 1.
The socket support plate 2 is shaped to fit into the slot 1b of B like a partition plate, and at the same time, the plate-shaped portion of the socket support plate 2 is provided with a hole of an appropriate shape for attaching, for example, a wedge-based light bulb socket. The support portion 2a is provided with a substantially U-shaped lens engagement groove 2c along the edge. At the same time, as shown from the back side in FIG. 2, this socket support plate 2 is provided with appropriate overhangs at positions corresponding to the base mounting holes 1c provided in the bases 1A and 1B, respectively, to form a cylindrical base. Mounting boss 2
b is provided.

By forming the bases 1A, 1B and the socket support plate 2 as described above, a light bulb and a light bulb socket (both not shown) can be attached to the socket support plate 2, and this socket support plate 2 can be inserted into the slot 1.
The bases 1A and 1B are fitted so as to butt against each other, and then the base mounting boss 2 is inserted from both sides with the base set screw 4 as shown in FIG.
By screwing it into b, it becomes one piece and forms the desired shape.

Further, the lenses 3A and 3B (the 3B side is not shown) are attached to the base 1, respectively.
It is formed of resin or the like into a shape that fits into the notch 1a of A, 1B, and the end 3a of one side is shaped to fit into the lens engagement groove 2c provided in the socket support plate 2, and the base Lens mounting hole 3 is almost similar to base mounting hole 1c explained in 1A and 1B.
b is provided, and as shown in FIG. 4, the base 1A,
Lenses 3A and 3B corresponding to lens 1B are engaged from both sides, and are screwed onto the lens attachment boss 1d with lens attachment screws 5 to form an integrated double-sided light emitting vehicle lamp. Incidentally, the reference numeral 6 in FIG. 4 is a light bulb socket, and the reference numeral 7 is a light bulb.

With this structure of the double-sided emitting vehicle lamp, the bases 1A and 1B can be made thin and made of resin, and the lenses 3A and 3B can be made of resin.
Also, the irradiation direction and the die cutting direction match, making it possible to perform lens cutting.

Note that the diagram does not show the waterproof structure provided in this type of lighting equipment or the positioning structure when fitting each part, but these are conventionally used when designing and manufacturing this type of lighting equipment. What is necessary is to utilize the means provided, and it is sufficient to carry out the measures as appropriate depending on the situation.

〓Effect of the invention〓 As explained above, according to the present invention, the structure of the double-sided light emitting vehicle lamp is divided into two parts perpendicular to the irradiation direction, and the base is formed into a thin wall with uniform thickness, and the cutout part is formed. A socket support plate is provided with a pair of substantially box-shaped socket support plates provided with a light bulb socket support portion for attaching a light bulb and a light bulb socket to the base, and a base attachment boss for fixing the base. By fitting into a plate shape and screwing it into one piece, and having a structure in which a lens is fitted and screwed into the notch of the base, the base can be formed with a thin wall, and it is possible to prevent appearance problems such as sink marks. It is possible to use resin without causing any problems, and it is effective in reducing the weight and cost of this type of double-sided light emitting type vehicle lamp.
