DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to ornaments such as ornaments, emblems and corner poles provided on automobiles. More specifically, the present invention relates to an interior provided with a light source in order to enable visual recognition even at night. Pertaining to the configuration of the decorative article.

[0002]

2. Description of the Related Art A conventional decorative article 9 of this kind for automobiles.
FIGS. 3 and 4 show an example of a corner pole in the configuration of FIG.
A display substrate 92 made of a resin or the like is attached to each opening surface of the case 91 formed of a metal, a resin, or the like so as to have an internal gap inside the case 91.

The display substrate 92 is provided with a light-shielding film 92a formed by painting or the like on the inner surface of the case 91, and is V-shaped cut from the light-shielding film 92a side to be transparent or translucent. And a display portion 92b showing, for example, a car name and a mark.
Is provided with one light source 93 using an incandescent lamp.

When the number of the light sources 93 is one, the illumination unevenness occurs in a position closer to the light source 93 and becomes brighter in a position farther from the light source 93, and becomes darker in a position farther from the light source 93. Therefore, as shown by a reference numeral 94 in FIG. In some positions, a wedge-shaped auxiliary reflection surface is provided by using the case 91 or formed separately, and the auxiliary reflection surface 94 is used to eliminate illumination unevenness.

[0005] With the above configuration, by turning on the light source 93, the portion of the display section 92b is illuminated by the transmitted light from the light source 93 and can be viewed. This also facilitates position confirmation. Further, the display substrate 92 is attached to the case 9.
1, the case 91 is attached to the vehicle body to provide an ornament and an emblem that can be displayed at night, thereby improving the decorative effect.

[0006]

However, in the above-described structure of the conventional decorative article 90 for a vehicle, when an LED lamp having a relatively narrow irradiation angle α is employed as the light source 93, the structure shown in FIG. As shown, the display portion 92b is illuminated only within the range of the irradiation angle α, which impairs the appearance of the decorative article 90 with lighting for automobiles, and thus cannot be practically adopted.

Therefore, it is inevitable to use an incandescent light bulb which emits light substantially uniformly in all directions as the light source 93. However, the incandescent light bulb has a problem of filament breakage. The provision of a replacement configuration is an absolute requirement. Therefore, the decorative article 90 with lighting for automobiles
In addition to the problem that the configuration is complicated and the cost is increased, there is also a problem that a burden is imposed on the automobile user such as labor for maintenance, and solving these problems has been an issue.

[0008]

According to the present invention, as a specific means for solving the above-mentioned conventional problems, at least one of the two light-shielding films of a display substrate provided with a light-shielding film on one surface has a transparent film. An optical section is provided to form a display section.
In a decorative article with lighting for automobiles, which is provided with a suitable internal gap on the light-shielding film side and provided with a light source in the internal gap on the light-shielding film side, a light source is provided in the internal gap on the side of the light source in the irradiation direction. Is a light guide plate 2 having a white reflective film formed on one surface.
For the automobile, wherein the light source is one of the LED lamps whose emission centers coincide with each other at the joint of the two light guide plates. The problem is solved by providing a decorative article with illumination.

[0009]

Next, the present invention will be described in detail based on an embodiment shown in the drawings. 1 and FIG.
Is a decorative article with lighting for an automobile according to the present invention (hereinafter, simply referred to as decorative article 1), and in this embodiment, an example in which the decorative article 1 is a corner pole will be described.

Also in the decorative article 1 of the present invention, the opening of each case 2 formed in a substantially frame shape with a metal, a resin, or the like is provided with an internal gap 2a inside the case 2 so as to be made of a resin or the like. And a pair of display substrates 3 are attached.
This display substrate 3 is the same as that of the conventional example in that a light shielding film 3a is provided on an inner surface of the case 2 by an appropriate means such as painting or printing.

A V-shaped cut is made from the side of the light-shielding film 3a, and if necessary, a translucent film of gold, silver or the like is provided in the V-shaped cut portion. It is the same as the conventional example in that one light source is provided in the internal gap 2a between the two display substrates 3 serving as display units 3b to be displayed.

Here, in the present invention, two light guide plates 5 are provided on the irradiation direction side of the light source in the internal gap 2a, and one of the light guide plates 5 is painted or screen-printed on one surface. The white reflective film 5a having a uniform thickness is formed by such means as that described above. When the white reflective film 5a is disposed in the internal gap 2a, the surfaces on which the white reflective film 5a is applied face each other. .

At this time, the outer diameter end face 5b of the light guide plate 5
When light reaching the outer diameter end face 5b reaches the outer diameter end face 5b as a smooth surface, the light is radiated without diffusion to the outside. A mirror surface 2b made of metal plating or the like is formed on the inner diameter facing the radial end face 5b, and the light emitted from the outer diameter end face 5b is reflected once, and then enters the light guide plate 5 again.

In the present invention, the light source may be an LED.
The lamp 4 is adopted.
Are inserted into the light source mounting recesses 5c provided on the two mating surfaces of the light guide plate 5, and at this time, the LED lamp 4 is arranged such that the light emission center is at the two mating surfaces of the light guide plate 5. , That is, the position of the white reflective film 5a.

Next, the operation and effect of the decorative article 1 of the present invention having the above-described configuration will be described. First, two light guide plates 5 having a white reflective film 5a provided on one surface thereof by means of painting or screen printing are provided with the surfaces on the white reflective film 5a side facing each other. Thus, the display portion 3 of the display substrate 3 is also provided by the LED lamp 4.
This enables uniform illumination of the entire surface b.

Since the pigment used in the paint or ink constituting the white reflective film 5a is a fine powder having a high reflectivity such as titanium oxide, for example, the light is incident on the white reflective film 5a. This is because even if the light is from a light source having directivity such as the LED lamp 4 that causes irregular reflection, a strong diffusion effect enough to lose the directivity can be obtained.

Second, the light source is LE as described above.
Since the D lamp 4 is used, the possibility of occurrence of a disconnection accident in the LED lamp 4 is negligibly low in a normal use state, and a light source exchange mechanism for preparing for this disconnection accident is omitted. You can do it.

Third, since the LED lamp 4 can be used as a light source, the calorific value is reduced as compared with a conventional incandescent lamp, so that heat resistance and the like need not be considered. Due to the emission of monochromatic light by the LED lamp 4, the color purity is increased even in the case of, for example, blue.

[0019]

As described above, according to the present invention, two light guide plates having a white reflection film formed on one surface are provided on the irradiation direction side of the light source in the internal gap so as to face the white reflection film side. The light source is a decorative article with lighting for automobiles, which is one of the LED lamps whose emission centers are matched at the joint of the two light guide plates. For this reason, it is possible to adopt an LED lamp with excellent reliability, which was previously impossible, as a light source, thereby simplifying the configuration by eliminating the need to provide a mechanism for replacing the light source in decorative accessories with lighting for automobiles. Thus, this type of decorative article has an extremely excellent effect on cost reduction.

Further, since the LED lamp can be used as the light source as described above, the amount of heat generated by the light source is reduced, and the use of a heat-resistant member as a component of the decorative article for vehicle lighting is eliminated. Also in this regard, the cost can be reduced, and the monochromatic emission of the LED lamp enables high-purity display to improve the quality, thereby exhibiting an excellent effect on the improvement of merchantability.
