Description

[Detailed description of the invention] <<Industrial application>> The present invention relates to a decorative lamp that is attached to the side of a car, for example, in the form of a side molding, and which emits light at night and also functions as a position lamp. be.

<Prior Art> As a conventional lamp of this type, there is one disclosed in Japanese Patent Publication No. 58-172801 by the same applicant, in which an EL light emitting element is integrated into a lens formed into a substantially box shape. It has become.

<<Problems to be solved by the invention>> However, the lifespan of the EL light-emitting element is said to deteriorate significantly due to humidity, and when used in a lamp that is directly exposed to rain, etc., and has harsh environmental conditions, it is difficult to use the above-mentioned lens. For example, sealing means such as resin molding is required when integrating the
In both cases, a large amount of processing time is required, resulting in the problem that this type of lamp using an EL light emitting element becomes expensive.

<Means for Solving the Problems> The present invention, as a specific means for solving the above-mentioned conventional problems, has a lens cut made with an appropriate lens cut such as a lens cut for a reflex reflector, and a mounting rib on the peripheral edge of the back side. A lens provided with a lens, a base provided with an approximately U-shaped lens mounting groove that fits into the mounting rib of the lens, and an EL holding rib, and an EL mounted between the lens and the base. The height of the inner peripheral side of the lens mounting groove of the base is approximately the same as the EL holding rib, and the height of the inner peripheral side of the lens mounting groove and the EL holding rib of the base is such that the lens By providing an EL accessory light for a vehicle in which the EL light emitting element is sandwiched between the lenses, the process of attaching the lens and the base simultaneously serves as the process of sealing and attaching the EL light emitting element, thereby reducing the number of man-hours. This is to solve the above-mentioned conventional problems.

<<Example>> Next, the present invention will be described in detail based on an example shown in the drawings.

What is indicated by the reference numeral 1 in FIG. 1 is an EL accessory light for a vehicle according to the present invention (hereinafter abbreviated as an accessory light).The back side of the lens 2 formed of transparent resin of this accessory light 1 is equipped with, for example, a reflex reflector. An appropriate lens cut 21 is provided for use, and a continuous mounting rib 22 is also provided on the peripheral edge of the back side. The base 3, which is also made of a resin material, is fitted with a substantially U shape that is fitted to sandwich the mounting rib 22.
A letter-shaped lens mounting groove 31 is provided, and an EL pressing rib 32 is also appropriately provided on the inner circumferential portion of the lens mounting groove 31. At this time, according to the present invention, the inner circumferential side of the lens mounting groove 31 and inner wall 31
The height of a is set to be lower than the outer wall 31b by the thickness of the EL light emitting element 4 used as a light source of the accessory light 1, and is approximately the same height as the EL holding rib 32.

Lens 2 and base 3 configured as explained above
To explain the process of assembling the accessory light 1 with the lens 2 and the EL light emitting element 4, first fill the lens mounting groove 31 of the base 3 with an appropriate amount of adhesive 5 such as hot melt, and then attach the lens 2 and the EL light emitting element 4. By inserting the mounting rib 22 of the lens 2 so as to overlap the element 4, the EL light emitting element 4 is sandwiched between the inner wall 31a and the EL holding rib 32 on the surface of the lens 2 where the lens cut 21 is provided. At the same time, the lens 2 is attached by the adhesive 5.
The internal space formed by the base 3 and the base 3 is completely isolated from the outside, and is airtight and sealed.

In addition, in implementation, for example, the inner wall 31a or the EL holding rib 32 explained in this embodiment may be
Similar effects and effects can be obtained by forming the surface with the lens cut 21 thinner instead of making the thickness of the EL light emitting element 4 lower than the outer wall 31b. Needless to say, this does not detract from the gist. Also, the EL used
If the light emitting element 4 has a thick central portion, the height of the inner wall 31a and the EL holding rib 32 can be adjusted as appropriate to match the EL light emitting element 4.

<<Effect of the invention>> As explained above, the lens has a mounting rib provided on the peripheral edge of the back side, a substantially U-shaped lens mounting groove that fits into the mounting rib of the lens, and an EL.
The base includes a base provided with a holding rib, and an EL light emitting element mounted between the lens and the base, and the height of the inner peripheral side of the lens mounting groove of the base is approximately the same as the EL holding rib. By having a structure in which the EL light emitting element is sandwiched between the inner peripheral side of the lens mounting groove and the EL holding rib, the accessory light of the present invention requires only the process of attaching the lens using an adhesive. The EL light emitting element can be installed at the same time, and the sealing can also be done at the same time, greatly reducing the number of steps and work time.
This is extremely effective in reducing the cost of EL accessory lights.
