〔Example〕

Hereinafter, the present invention will be described in detail with reference to embodiments shown in the accompanying drawings.

FIG. 1 is a perspective view showing an example of the decorative light emitting device of the present invention applied to earrings, and FIG. 2 is a schematic sectional view of the main part of FIG. 1.

In the figure, l is a cover, 2 is a power supply, 3 is a switch part,
4 is a chip of a light emitting element, 5 is a lead wire, 6 is an envelope (casing), and 9 is an earring attachment part. Envelope 6
is a conductive material that also serves as a decorative part, and is made of materials valuable as decorative items, such as gold, platinum, silver, plated metals, other metals, and alloys.

In short, the envelope 6 also serves as a decorative portion and electrically plays the role of one electrode. Further, the material of the envelope 6 may be electrically conductive, and may be decoratively designed. A light emitting element chip 4 is provided inside the envelope 6 .

This chip 4 is the same in the following embodiments, and although explanation will be omitted in the following embodiments, it may be one or more chips.

In terms of materials, for example, GaAlAs, GaP, Zn
They are made of compound semiconductors such as 5e and InGaP, and emit luminescent colors such as red, green, blue, and yellow, respectively.

The size of the chip 4 of the light emitting element depends on the design, but in this example it is about 300 μm square.

The chip 4 of the light emitting element is provided in a part of the envelope 6, and the light emitted from the chip 4 is taken out to the outside through the cover 1.

The cover 1 is made of a translucent material (it may be colored), such as transparent, translucent, or milky white glass or plastic.

Of course, a pattern may be applied to the front or back surface of the cover 1. The pattern may be drawn directly on the material (front and/or back) or processed, it may be indented into a mosaic pattern, or the surface may be inlaid with jewels or the like.

Conversely, the cover 1 is not an absolutely essential element for the present invention, and may be omitted, and may have a structure that directly extracts light from the chip 4 of the light emitting element to the outside.

The power source 2 is composed of a mercury battery or a lithium battery, and one electrode is electrically connected to the switch section 3.

In this example, a mercury battery is used as the power source 2, and a rotary switch is used as the switch section 3, but the power source 2 may be any other battery, such as a rechargeable dry battery, and the switch section 3 may be a slide switch or the like.

The terminals of the switch section 3 are guided by a lead wire 5 made of a material such as gold or copper, which is connected to one electrode of the chip 4, and are led by a terminal 7 and a lead wire 10, which are insulated from the envelope 6. It is connected.

In this specific example, the envelope 6 is divided into upper and lower parts, and when one of the envelopes 6 is rotated via the rotating section 8, the contact of the rotary switch of the switch section 3 is changed to the adjacent switch contact ' The current flows through the chip 4, which has become a closed circuit, and lights up.

Note that the lead wire 10 is not necessarily necessary (it may be formed in a structure in which the contact of the switch section 3 and the chip 4 are directly connected).

FIG. 3 is a schematic diagram showing an example of a chip arrangement of light emitting elements in the earring shown in FIG.

A plurality of light emitting element chips 4 are arranged at random, and are connected to one electrode of the light emitting element chips via lead wires 5 from electrode terminals 7 insulated from the envelope 6.

Note that the number, arrangement, etc. of chips can be freely changed in terms of design.

The chip 4 can emit light of different colors at the same time, or can visually mix colors as desired.

That is, for example, by emitting red light from GaAlAs and yellow light from InGaP at the same time, an orange color can be obtained, or by changing the light intensity of each light, a red-orange color or a yellow-orange color can be obtained.

FIG. 4 shows another example of the decorative light emitting device of the present invention, in which the decoration of the earring cover 1 explained in FIG. 1 is changed.

In this specific example, a glass ball or jewel 11 is attached to the side surface of the cover 1 below the outer enclosure 6, and the lower end thereof is made of glass 12. A chip of a light emitting element and a battery as described above are provided inside, and the light emitting element is caused to emit light by operating the switch section 8, and the light is emitted from all sides of the cover 1 to the outside.

The cover 1 and the envelope 6 may have any design as long as they do not spoil the aesthetic appearance.

FIG. 6 is an electrical wiring diagram of the specific example shown in FIGS. 1 and 4.

In the figure, 20 is the movable part of the switch section, 22, 23...
- 27 is a plurality of chips 28-1.28-2.・・・・・・
・Terminal connected to 28-n, 21 is open circuit terminal, 2
9 is a power supply section.

When the movable part 20 of the switch comes into contact with 22, the chip 28
When -1 comes into contact with 27, the chip 28-n lights up.

In order to light up a plurality of chips at the same time, the structure of the movable part 20 may be made into a plurality of pieces, or an IC switch may be used. Furthermore, the emission intensity of each chip can be changed by connecting a constant current element such as a constant current diode in series with the power supply 29 or in series with each chip.

Up to now, the present invention has been described using an example in which a rotary switch is used as a switch section, but the switch section of the present invention is not limited to a rotary switch.

FIG. 5 shows another example of the decorative light emitting device of the present invention, in which a photoconductive element is used in the switch section of the earring.

Rotary switches and slide switches are configured to mechanically switch on and off, but photoconductive elements can be switched electrically.

In the figure, numeral 9 denotes a photoconductive element consisting of a photodiode and a phototransistor, which electrically replaces the rotary switches in FIGS. 1 to 4 and 6.

The photoconductive element 9 detects external illuminance and changes the amount of light output from an internal light emitting element chip (not shown) according to the external illuminance.

With this configuration, a new decoration can be superimposed on the new light decoration.

The decorative light emitting device of the present invention has been described above using earrings as an example, but the present invention is applicable not only to earrings but also to various ornaments, and will be described next using a pendant as an example.

FIG. 7 is a side sectional view showing an example in which the decorative light emitting device of the present invention is applied to a pendant.

In the figure, 21 is a cover, 22 is a power source, 24 is a light emitting element chip, 25 is a lead wire, and 26 is an envelope, and these are the cover 1, power source 2, and light emitting element chip shown in FIGS. 4, the lead wire 5 and the envelope 6 have the same functions, so their explanation will be omitted.

One electrode terminal 27 of the chip 24 serves as a contact point of a rotary switch, and is insulated by an envelope 26 and an insulating plate 23. In this example, the contacts of the rotary switch are switched by rotating the envelope 26.

Figure 8 is a cross-sectional view taken along the line A-A' in Figure 7, showing the arrangement of light emitting elements.This is an example of a case where they are arranged concentrically, and the number of light emitting elements, arrangement, etc. It can be changed in any way depending on the situation.

FIG. 9 is a sectional view taken along the line B-B' in FIG. 7, showing the lower contact portion of the rotary switch, and shows the electrode plate 28.
is incorporated into the insulating plate 23. The reason why the electrode plate has a cross shape is because it is structured so that four light emitting element chips light up at the same time.If you change the shape of this electrode plate, you can light up from one to eight chips at the same time. Can be done.

If the terminal 27 is rotated so that it comes to the insulating part other than this contact, the light goes out. In this case as well, the envelope is made of precious metal or the like, and if a decorative design is applied to the surrounding area, the effect as an accessory will be further enhanced.

FIG. 10 shows a cross-sectional view of an example in which the battery part 22 is moved to the upper part of the pendant. This makes it possible to achieve a thinner shape.

FIG. 11 is an external view of FIG. 10. By applying a decorative pattern to the surface and surrounding area of this envelope, it is possible to further enhance the performance effect as an accessory.

Further, FIG. 12 is a partially cutaway view showing an example in which the switch portion of the present invention is devised so that it can be opened and closed according to the movement of the wearer, and FIG. The switch part of the earring shown in Figure 1 is structured so that the switch is turned on only at the moment two conductive metals come into contact with each other.

As shown in the figure, a chain-shaped conducting wire 31 hangs downward from a contact portion that contacts one electrode of a battery 30, and a metal ball 32 is attached to its tip. Around the metal sphere 32, six hemispherical metal electrodes 35 are provided, which are insulated by an envelope 33 made of a conductive material and an insulating member 34. The external spherical electrode 35 is connected to the chip 36 of each light emitting element by a conductive wire.
The other pole of the light emitting element is in contact with the envelope 33. Cover part 37 at the position of the chip 36
is provided so that the emitted light can be extracted to the outside. When the metal ball 32 comes into contact with the hemispherical metal electrode 35 as the earring swings, the light emitting element that has formed a closed circuit with the hemispherical electrode in contact emits light for a moment. The light emitting elements randomly turn on and off depending on how the earring swings, and when the metal ball 32 contacts two hemispherical electrodes 35 at the same time, the two light emitting elements may light up.

When not in use or when light emission is not required, the envelope 33
When the upper lid 38 is loosened, the conductive metal guide 39 that is in contact with the upper snow plow of the battery 30 and the envelope 33 are disconnected (Figure 12 shows this state), so the power switch is turned off. become.

As a switching method in the present invention, in addition to the above-mentioned switches using a rotary switch or a light sensor, a temperature or heat-sensitive sensor such as a thermistor using an oxide semiconductor ceramic or the like can also be used as a switch. By using PTCSNTC, CTR, etc., the switch can be turned on and off in response to external temperature changes.
The light emission intensity can also be changed by turning it off or by utilizing changes in thermoelectromotive force due to temperature changes.

Also, for batteries, in addition to those mentioned above, Si.

Solar cells that utilize the photovoltaic effect of semiconductor elements such as GaAs may also be used, so that they can emit light even in dark places or at night.
It can also be combined with a rechargeable battery.

In this way, there is no need to replace batteries.

As described above, by using various sensing elements as switches, the decorative light emitting device of the present invention can provide accessories with a wide variety of decorative effects under various situations.

Although the decorative light emitting device of the present invention has been described above using several specific examples, the present invention is not limited to the above embodiments. Any structure may be used as long as it has one or more light emitting element chips and a power source inside the device.
