Description

[Detailed Description of the Invention] The present invention relates to a light-emitting device that is attached to various accessories such as brooches and bags and emits blinking light.

Traditionally, accessories such as brooches,
There are products on the market that have light-emitting diodes embedded in the surface that flash irregularly, and their novelty has led to them selling well.

The light-emitting device of the above-mentioned accessory is made up of, for example, a sound-collecting microphone, a signal processing circuit, a light-emitting diode, and a power source using a small battery. control the connection, disconnection, and interval of
Since the diode is configured to blink irregularly, it must be quite expensive, and due to its configuration, a power switch is indispensable. It requires opening and closing the switch, and there is also the problem that the battery will be consumed if you forget to turn the switch off.

In view of the above-mentioned points, the present invention provides a light-emitting device that blinks light-emitting diodes irregularly without using special parts such as a sound-collecting microphone or a signal processing circuit, and also does not require a power switch. It was designed for the purpose of a movable contact forming a shape, one or more rod- or needle-shaped fixed contacts fixedly provided on the mounting part opposite to and close to the movable contact, and one terminal of which is connected to the other side of the battery. and one or more light emitting diodes connected to the electrode of the fixed contact and having the other terminal connected to the fixed contact, respectively.

Next, embodiments of the present invention will be described with reference to the drawings.

Reference numeral 1 denotes a button-shaped battery such as a mercury battery, and here two small-pole batteries 11 are connected in series. here,
The reason why a plurality of small batteries 11 are used is to obtain enough output to blink a plurality of light emitting diodes for a long period of time using commercially available inexpensive button-shaped batteries.

Reference numeral 2 denotes a planar movable contact that is swingably suspended from a support frame F, which will be described later, via a hanging member 21 such as a conductive string. The formed electrode is used to connect to one electrode of the battery 1, here the anode 1a.

Reference numeral 3 denotes a rod-shaped fixed contact provided on a mounting portion B positioned opposite to the movable contact 2 so as to protrude toward the rough surface 22 side of the contact 2. Each of the fixed contacts 31 to 33 of this embodiment will be described later. Each of the diodes 41 to 43 is connected to one terminal 41a to 43a, respectively, and here, the contacts 3 and 4 form a switch device S.

4 is a light emitting diode, and accessory A is the light emitting part.
One terminal 41a of each of the diodes 41 to 43 can be attached to a plurality of diodes as appropriate by exposing them to the surface.
-43a are respectively connected to the fixed contacts 31-33 via lead wires 41l-43l, and the other terminals 41b-43b are connected in parallel to the cathode 1b of the battery 1 via lead wires 41r-43r. The above constitutes an example of the light emitting device of the present invention.

The light emitting device has the button battery 1 supported by the boulder 1H and the switch device S attached to the back side of the main body of the accessory A, and the light emitting diodes 41 to 43 are installed at appropriate locations on the front side. By exposing and attaching the light emitting part of the accessory A, it functions as a light emitting device of the accessory A.
In addition, the above-mentioned switch device S here has a movable contact 3.
A supporting frame F is formed to function as a mounting frame for the accessory A, and a mounting portion B of the fixed contact 3 is also supported by the frame F.

That is, when the accessory A moves, the movable contact 2 of the switch device S attached to it swings, and its rough surface 22 contacts each of the fixed contacts 31 to 33 irregularly. Therefore, each of the light emitting diodes 41 to 43 connected to the battery 1 blinks irregularly. This irregular blinking
This is facilitated by the fact that the surface of the movable contact 2 is formed into a rough surface 22, but each contact 2 and 31 to 33
In order to encourage irregular contact between the hanging members 21
Alternatively, a vibrating body such as a coil spring may be used for the fixed contacts 31 to 33.

In this way, in the switch device S of the device according to the present invention, the movable contact 2 swings to connect the fixed contacts 31 to 31.
Since it is only necessary to contact and separate from the switch 33 irregularly, a switch device having a structure as shown in FIG. 3 may be used as this switch device.

In FIG. 3, 2' is formed of a round bar or cylindrical conductor, and movable contacts 31' to 33' suspended from the support frame by hanging members 21 are connected to the contact 2'. A cylindrical attachment part surrounding the outer periphery at a distance from it.
When the switch device S' is configured in this way with a movable contact protruding toward the fixed contact 2' on the peripheral wall of B',
The irregular contact state between both contacts 2' and 31' to 33' is further promoted, and since a large number of fixed contacts can be provided around the periphery of the attachment part B', a large number of light emitting diodes can be connected. This means that it can be made to blink irregularly.

The light emitting device configured as described above is assembled into the accessory A by exposing the light emitting diode 4 on the surface of the accessory A as appropriate, attaching the switch device S and the battery 1 to appropriate locations on the back surface, and incorporating the light emitting device into the accessory A. When the accessory A is worn and the wearer moves, the movable contact 2 swings and irregularly connects and disconnects the light emitting circuit of each light emitting diode, thereby causing each light emitting diode to emit light irregularly. and enhance the accessory effect.

When the accessory A is not in use, if the accessory A is placed so that the fixed contact 3 is positioned above the movable contact 2, the switch device S will not become conductive. A separate on/off switch may be provided to turn it off.

Further, the application of the light emitting device of the present invention is not limited to the accessories of the embodiments, but may also be applied to other appropriate articles such as toys and bags.

Since the present invention is as described above, it is suitable as a light emitting device to be incorporated into an accessory or the like.
