Photosensitive button structure

Abstract

A photosensitive button structure includes a button body and a photosensitive layer. The photosensitive layer is disposed on a bottom side of the button body, and has a plurality of words and pictures formed thereon. Whereby, the photosensitive layer produces a first color change by absorbing light from one angle, and then produces a second color change or more than two color changes by absorbing light from another angle, in order to produce a dual mold visual effect. The present invention solves problems and the defects of the traditional button having only one fixed color, and that the color of the traditional button can only be changed once, because the photosensitive layer can absorb light from different angles. Hence, the present invention not only improves the appearance of the button body, but can also show more than two color changes of any words or pictures on the button structure.

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a photosensitive button structure, and particularly relates to a photosensitive button structure having a photosensitive layer for absorbing light from different angles in order to produce color changes, and a dual mold visual effect on a button body.

2. Description of the Related Art

In general, a traditional button has a fixed color that is decided in the manufacture process and cannot be changed thereafter. If the color of the button needs to be changed, the general method is to dispose a light-emitting element under the button. When the color of the light-emitting element changes, the color of the button is changed.

However, the color of the button with the light-emitting element can only be changed once, and the manufacturing cost of the button with the light-emitting element is increased.

SUMMARY OF THE INVENTION

The present invention provides a photosensitive button structure. The photosensitive button structure has a photosensitive layer for absorbing light from different angles, in order to produce color changes and a dual mold visual effect on a button body. Furthermore, any words, characters or images on the button will be clearly visible while the background color can be changed because of their dual mold visual effect. Hence, the present invention not only improves the appearance of the button body, but can also display more than two color changes of the words and/or the pictures.

One aspect of the invention is a photosensitive button structure. The photosensitive button structure includes a button body and a photosensitive layer. The photosensitive layer is disposed on a bottom side of the button body, and has a plurality of words and pictures formed thereon. Whereby, the photosensitive layer produces a first color change by absorbing a light source. The photosensitive layer then produces a second color change or more than two color changes by absorbing light from another angle, in order to produce a dual mold visual effect.

It is to be understood that both the foregoing general description and the following detailed description are exemplary, and are intended to provide further explanation of the invention as claimed. Other advantages and features of the invention will be apparent from the following description, drawings and claims.

BRIEF DESCRIPTION OF THE DRAWINGS

The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing, in which:

FIG. 1 is a side, schematic view of a photosensitive button structure according to the present invention;

FIG. 2 is a top, schematic view of a photosensitive button structure according to the first embodiment of the present invention; and

FIG. 3 is a top, schematic view of a photosensitive button structure according to the second embodiment of the present invention.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

FIG. 1 shows a side, schematic view of a photosensitive button structure according to the present invention. The photosensitive button structure includes a button body 10 and a photosensitive layer 20.

The button body 10 is made of plastic or resin materials. The photosensitive layer 20 is made of a uniform mixture of photosensitive material, and printing ink or paint. Moreover, the photosensitive layer 20 is disposed on the bottom side of the button body 10 by a printing or a coating method. Furthermore, the photosensitive layer 20 has a plurality of words 30 or pictures (not shown) formed thereon by a printing or a laser carving method.

FIGS. 2 and 3 respectively show a top, schematic view of a photosensitive button structure according to the first and the second embodiments of the present invention. Referring to FIG. 2, the photosensitive layer 20 produces a first color change by absorbing a light source, and then produces a second color change or more than two color changes by absorbing light from a another angle, in order to produce a dual mold visual effect on the button body 10, or clearly show the words 30 and background color (the photosensitive layer 20) because of their dual mold visual effect. Referring to FIG. 3, the photosensitive layers 20 can be respectively disposed on different button bodies 10 to clearly show the words 30, when the photosensitive layers 20 absorbs light from different angles.

The present invention solves the problem and the defect that traditional buttons have only one fixed color, or that the color of the traditional button can only be changed once as the photosensitive layer 20 is able to absorb light from different angles and display a dual mold visual effect. The present invention not only improves the appearance of the button body 10, but it also allows more than two color changes of words or pictures to be displayed on a button body 10.

Although the present invention has been described with reference to the preferred embodiments thereof, it will be understood that the invention is not limited to the details thereof. Various substitutions and modifications have been suggested in the foregoing description, and others will occur to those of ordinary skill in the art. Therefore, all such substitutions and modifications are intended to be embraced within the scope of the invention as defined in the appended claims.

Claims

1. A photosensitive button structure comprising: a button body; and a photosensitive layer disposed on a bottom side of the button body, and having a plurality of words and pictures formed thereon; whereby, the photosensitive layer produces a first color change by absorbing a light source, and then produces a second color change or more than two color changes by absorbing light from different angles, in order to produce a dual mold visual effect.

2. The photosensitive button structure as claimed in claim 1, wherein the button body is made of plastic or resin materials.

3. The photosensitive button structure as claimed in claim 1, wherein the photosensitive layer is made of a uniform mixture of photosensitive material and printing ink.

4. The photosensitive button structure as claimed in claim 1, wherein the photosensitive layer is made of uniform mixture of photosensitive material and paint.

5. The photosensitive button structure as claimed in claim 1, wherein the photosensitive layer is disposed on the bottom side of the button body by a printing or a coating method.

6. The photosensitive button structure as claimed in claim 1, wherein the words and pictures are formed on the photosensitive layer by a printing or a laser carving method.
