Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a light-emitting display switch device for power supply of various electronic devices using a general household power supply.
[0002]
[Prior art]
Conventionally, in order to prevent forgetting to turn off the power supply, many electronic devices have been configured to emit light with a highly visible light source, such as a bean ball or LED, to indicate that the power supply has been turned on.
[0003]
Recently, some cases where EL (ELECTROLUMINESCENCE) light-emitting elements are used as the light source of the light-emitting display part have been seen. For example, it is shown in Japanese Patent Application No. 11-34438.
[0004]
[Problems to be solved by the invention]
In the conventional light emitting display device, when general household power is turned on, AC power cannot be directly supplied to the LED, or even if it can be supplied, a bean ball or LED mounting space is required. In addition, the light emitting area is small and the shape cannot be freely configured. In addition, it has been impossible to confirm the presence or absence of light emission of light emitters such as bean balls and LEDs unless the line of sight is directed to the mounting position.
[0005]
The light-emitting display unit employing the EL light-emitting element is not far from the visibility of conventional bean balls and LEDs due to low brightness when general household power is supplied directly to the EL light-emitting element. Further, in order to increase the luminance, it is necessary to increase the voltage or increase the frequency to about 400 Hz, which makes the circuit configuration very complicated.
[0006]
The present invention has been made in view of the above-mentioned matters, and comprises the resin disposed under the same plane as the insulating translucent resin and the EL light emitting element of the same color when not emitting light. To provide a light-emitting display switch device that has the same color as an insulating translucent resin when emitting light, but has a hue different from that of the insulating translucent resin due to light emission of the EL itself when emitting light, and has excellent visibility due to the difference in hue. With the goal.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, a light emitting display switch device according to claim 1 is composed of the resin disposed below the same surface as an insulating translucent resin and an EL light emitting element of a similar color when not emitting light. A light-emitting display switch device comprising: a display unit configured to supply power to the EL light-emitting element according to the presence or absence of power supply.
[0008]
The light-emitting display switch device according to claim 2 is a light-emitting display in which an opaque paint or resin having a similar color to the resin is partially loaded between an insulating translucent resin and the EL light-emitting element. It is a switch device.
[0009]
In this device, it has been realized that characters and pictures are displayed by the configuration of the opaque part and the light transmissive part by paint or film.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
In order to illustrate the present invention more specifically, examples will be described below with reference to the accompanying drawings.
[0011]
[Example 1]
In the present embodiment, the first and second aspects of the invention will be described with reference to FIGS. FIG. 1 is a plan view of a light emitting display switch device according to a first aspect. FIG. 2 is a plan view of the light emitting display switch device according to the second aspect. FIG. 3 is a cross-sectional view of the light emitting display switch device according to the second aspect.
[0012]
In the apparatus of this embodiment, when the switch (4) is turned on, the power is supplied to the EL light emitting element (2) at the same time as the power is turned on to emit light. The insulating translucent resin (1) and the EL light emitting element (2) of the light emitting display section are composed of similar colors, and there is no change in the hue during the OFF operation, and the EL light emitting element (2) emits light during the ON operation. Only the surface where the EL light emitting element (2) and the insulating translucent resin (1) are bonded changes the hue, and the color of the surface not bonded to the EL light emitting element (2) does not change. It is configured to recognize ON and OFF based on the difference. Of course, the EL light emitting element (2) may emit light during the OFF operation.
[0013]
With this configuration, the low luminance of the EL light emitting element (2) is compensated for by a change in hue, and the EL light emitting element (2) can be easily visually recognized even in the daytime. In addition, if the display unit is configured in a plurality of positions or in a strip shape, it can be easily viewed from four directions, which is very effective.
[0014]
In addition, a current limiting resistor (3), a capacitor, or the like may be disposed on the connection path between the switch (4) and the EL light emitting element (2) as appropriate.
[0015]
[Example 2]
This embodiment explains the invention described in claim 2. In this example, a transparent resin film (7) in which a mark of ○ is impermeable printed with the same color is loaded between the insulating translucent resin (1) and the EL light emitting element (2) in Example 1. When the switch is turned on, only the EL light-emitting element transmission surface (7a) changes its hue and displays a circle mark.
[0016]
With this configuration, various designs and characters can be displayed.
[0017]
【The invention's effect】
The issuance display switch device of the present invention significantly improves the daytime visibility of low-luminance EL light-emitting elements, and even in its configuration, it can be directly connected to a household power supply, and thus has a very simple structure. In the mounting, if a film-like EL light emitting element is used, it can be easily mounted on a cylindrical structure or the like.
