Description

[Detailed explanation of the idea] This invention relates to an edge-lit lighting device.

The Edge-Ray 1 type illumination device illuminates characters by using both edge light and transmitted light, and usually has a structure as shown in FIG.

That is, 50 is a transparent acrylic body, and an edge light 51 is provided at the edge portion of this body.

On the surface of the acrylic body 50, a trim plate 52 on which characters for display are printed is attached with double-sided adhesive tape 53.

Light from the edge light 51 passes through the acrylic body 50 and reaches the trim plate 52, illuminating characters and the like.

However, in such a conventional edge-light lighting device, the adhesive tape 53 is attached to the acrylic body 50 and the trim plate 5.
Since the adhesive tape is adhesively bonded over the entire surface of the adhesive tape, light is diffusely reflected by the adhesive tape, resulting in loss of light quantity and unevenness of light.

Therefore, in the conventional type, it was necessary to illuminate a small area or increase the number of lamps 51.

In order to improve this drawback, some devices with a large surface area are fixed with adhesive tape 53 at only a portion of the corner, as shown in FIG. 2, to prevent loss of light quantity.

However, if this item is narrow and long,
There was a problem in that it was not possible to apply adhesive tape only to the corners; unless it was applied to the entire surface, assembly would be difficult and workability would be extremely poor.

In addition, when incorporating a lighting device into an S-power system, a third
As shown in the figure, a trim plate 52 is pasted on the stepped portion b of the S-force tensioner a, and an acrylic body 50 is attached to the trim plate 5.
There is also one that was installed with a slight separation from 2.

However, when the trim plate 52 is thin and long, when the trim plate 52 is pressed near the center, the trim plate 52
2 may be distorted, and since the bonding surface is reduced, there is a problem in terms of strength, which makes it easy to peel off.

The present invention was made to improve the drawbacks of the conventional device as described above, and by providing a rib on the acrylic body and fixing the trim plate to the rib with adhesive tape attached to the entire surface of the plate, It is an object of the present invention to provide a lighting device that reduces loss of light quantity, has a strong structure, and is easy to assemble.

Embodiments of this invention will be described below based on the drawings.

In FIGS. 4 and 5, 1 is an acrylic body, 2 is a trim plate, 3 is a double-sided adhesive tape, and 4 is an edge light.

On the surface of the acrylic body 1 to which the trim plate is attached, ribs 10 are provided in the longitudinal direction around the surface and at appropriate intervals.

The position of this rib 10 is such that the display 20 such as characters and symbols on the trim plate 2 is removed, and the rib 10
Make sure it doesn't go to 0.

A double-sided adhesive tape 3 is adhered to the entire back surface of the trim plate 2, and the trim plate 2 is fixed to the rib 10 via the tape 3.

In the above structure, since the portion of the adhesive tape 3 supported by both the acrylic body 1 and the trim plate 2 is reduced, the loss of light quantity is reduced.

Further, since the adhesive tape 3 is attached to the entire surface of the trim plate, workability is improved.

Furthermore, since the trim plate 2 is fixed to the refrigerant 10, it is strong in strength without being distorted or peeled off.

In addition, when this lighting device is assembled into an S-force tensioner, it may be incorporated as is, but as shown in Fig. 6, the upper and lower ribs are replaced by the stepped portion b of the S-force tensioner a, and the acrylic body is used. 1 may be formed with only vertical ribs 10.

As explained above, the lighting device according to the present invention has little loss of light quantity, and does not cause light unevenness even with a small amount of edge light.

Further, it has excellent effects such as no distortion or peeling of the trim plate, and furthermore, assembly is easy and workability is good.
