Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a lighting button for displaying, for example, an operation state of a home electric appliance.

[Prior Art] As shown in FIG. 4, a conventional lighting button 1A is made of a transparent synthetic resin and is formed in a box shape having a lower opening, and is provided on an outer surface of a case 2A having a mounting foot 2a protruding below a central portion. A coating film 3 of a dark color such as black is formed on the top surface of the coating film 3 by burning a display figure 4 (FIG. 1) such as a character or a mark with a laser beam. The case 2A is exposed, and the display figure 4 is displayed by the illumination light of an illumination lamp (not shown) provided below the case 2A.

[Problem to be Solved by the Invention] In the conventional illumination button 1A, since the case 2A is transparent, the illumination light from below causes a shadow of the mounting foot 2a on the display figure 4 on the upper surface of the case 2A, There is a disadvantage that the display figure 4 is difficult to see.

To solve this, it is conceivable to diffuse the light by applying a satin finish on the surface of the transparent case 2A, but a special mold for the satin finish is required, which increases the cost, and also reduces the intended satin finish. There is a problem that it is difficult to obtain and causes uneven light diffusion.

Therefore, the present invention, in the lighting button with the mounting foot, to prevent the effect of the mounting foot,
Further, it is intended to provide an illumination button which can be manufactured at low cost.

[Means for Solving the Problems] According to the present invention, there is provided a case made of a transparent synthetic resin and formed in a box shape having a lower opening, and having a mounting foot protruding below the central portion,
An outer case made of a translucent synthetic resin is joined to the outer surface of the case, a dark-colored coating film is formed on the outer surface of the outer case, and characters, marks, and other display figures are printed on the top surface of the dark-colored coating film with a laser beam. It is formed to expose the outer surface of the case.

The translucent synthetic resin is preferably a transparent acrylic resin or an ABS resin mixed with, for example, a milky white pigment to have a transparency of 30 to 50%.

[Operation] According to the illumination button configured as described above, light entering the transparent case from below is diffused and uniformed in the translucent outer case including the shadow of the mounting foot. Therefore, the display figure on the upper surface of the outer case has no shadow of the mounting foot.

In addition, unlike the case in which the transparent case itself is subjected to satin finish to diffuse light, a special mold is not required, and problems such as uneven light diffusion do not occur.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

In these drawings, portions corresponding to those in FIG. 4 are denoted by the same reference numerals, and redundant description is omitted.

In FIGS. 1 to 3, the case 2 of the lighting button 1 is formed in a shape excluding the flange portion 2b of the case 2A shown in FIG.
An outer case 5 made of a translucent synthetic resin and provided with 5a is joined. A dark paint film 3 is formed on the outer surface of the outer case 5, and a display figure 4 is formed on the top surface of the paint film 3. As the translucent synthetic resin, a transparent acrylic resin or an ABS resin mixed with, for example, a milky white pigment to have a transparency of 30 to 50% is used.

With such a configuration, light entering the transparent case 2 is transmitted to the translucent outer case 5 including the shadow of the mounting foot 2a.
It is diffused and uniformed within. Therefore, the shadow of the mounting foot 2a does not appear on the display figure on the upper surface of the outer case 5.

[Effects of the Invention] The present invention is configured as described above.
The light entering the transparent case from below is diffused and uniformized in the translucent outer case including the shadow of the mounting foot, and the display figure on the upper surface of the outer case shows the light of the mounting foot. No shadow is generated, and the displayed figure can be easily seen.

In addition, it does not require a special mold to diffuse light, unlike a transparent case with a satin finish, and simply provides a semi-transparent case outside the transparent case and provides it at low cost. Is what you can do.
