Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a glowing decoration in which a built-in LED is turned on only when placed at a specific position such as a display cabinet.

[0002]

SUMMARY OF THE INVENTION An object of the present invention is to provide an LED provided inside only when it is placed at a specific position where a primary coil is provided, powered by electromagnetic induction and turned on. It is to provide a glowing decoration that is going to disappear.

[0003]

In order to attain the above object, the present invention provides a glowing decorative article having a secondary coil provided on the bottom or back of an object which is at least partially transparent or translucent. At least two LEDs connected in anti-parallel to a secondary coil are provided on a transparent or translucent portion of the object, and the object is placed at a predetermined position where a primary coil through which a high-frequency current flows is provided, and the secondary coil is provided. The LED is turned on when the LED is placed close to and opposed to the primary coil. Also, a plurality of secondary coils each connected to an LED are provided on the object at a distance from each other. Further, the object is characterized in that a plurality of secondary coils are provided on the object so that the plurality of primary coils can be respectively arranged in close proximity to each other.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a perspective view showing a glowing decorative article according to the present invention. The glowing decoration 1 has two secondary coils 3A on the bottom surface of the (opaque) base end of an object 2 that is transparent or translucent at least in part (for example, the entire upper side excluding the base end). Buried a little away from 3B,
Two chip-shaped LEs between both terminals of each secondary coil
D4A and 4B are connected in anti-parallel and
A and 4B are arranged in a transparent or translucent part on the upper side of the object 2. The material of the object 2 may be glass, plastic, porcelain, or any other material that can be formed at least partially in a transparent or translucent manner (to the extent that the LED is dimly lit when the LED is lit). (Opaque metals, stones, wood, etc.).

[0005] FIG. 2 is a perspective view of a power supply device for supplying power to a shining ornament without connection. The power supply device 5 includes an inverter 6 for converting a commercial power supply or a battery power supply into a high-frequency current, and a primary coil 7 connected to an output of the inverter 6. The primary coil 7 is embedded in a thin sheet member 8. Decorative article 1 shining on this sheet-like member 8
And any one of the secondary coils 3A and 3B is the primary coil 7
When the primary coil 7 is arranged so as to face and oppose, a current proportional to the reciprocal of the winding ratio flows from the primary coil 7 to the opposed secondary coil by electromagnetic induction, and the LED 4A or 4B connected to the secondary coil turns on.

Now, when the sheet-shaped member 8 is laid on an ornamental shelf or the like, and the shining decorative article 1 is placed on the sheet-shaped member 8 so that the secondary coil 3A is arranged just opposite to the primary coil 7, The entire upper side of the decoration 1 illuminated (eg, red) by the LED 4A connected to the next coil 3A is colored (red). When the shining decoration 1 is moved to the left from this position and the secondary coil 3A moves away from the primary coil 7, the LED 4A is turned off. Next, when the secondary coil 3B is moved to a position where the secondary coil 3B faces the primary coil 7, the LED 4B is turned off. Lights (for example, blue).

FIG. 3 is a perspective view of another power supply device. The difference from the power supply device of FIG.
The two primary coils 7A and 7B are inside the secondary coils 3A and 3A.
B is buried at the same interval as B, and these are connected in series to the output of the inverter 6, and the others are exactly the same. With the decorative article 1 shining on the sheet-like member 8, the secondary coils 3A and 3B
A and 7B are opposed to each other so that both LEs
D4A and 4B can be turned on simultaneously. The decoration 1 that shines from this position is moved to the right and the secondary coil 3A
Is arranged to face the right primary coil 7B, only the LED 4A connected to the secondary coil 3A is turned on. Conversely, when the shining decoration 1 is moved to the left so that the secondary coil 3B is arranged to face the primary coil 7A, only the LED 4B is turned on.

In the above embodiment, the primary coil of the power supply device is provided in a thin sheet-like member, but may be directly buried in a decoration shelf or the like. Further, the number and arrangement of the primary coils are not limited to the above-described embodiment, and the design can be appropriately changed. Further, the number of secondary coils provided on the shining decoration is not limited to two, and may be one or three or more. The number of LEDs connected to each secondary coil is not limited to two, and may be as required. Any number may be provided.

Further, in the above embodiment, two secondary coils are provided on the bottom surface of the illuminated ornament, but they may be provided on the back of the illuminated ornament. It goes without saying that the primary coil is provided at a position corresponding to the secondary coil on the rear wall surface such as a display cabinet. Still further, a plurality of secondary coils may be provided on both the bottom surface and the back surface of the illuminated decoration.

[0010]

As described above, the glowing decorative article of the present invention can turn on the built-in LED only by placing it at a specific position such as an ornamental shelf, and the glowing decoration can be provided by providing a plurality of secondary coils. The color or lighting position connected to each secondary coil is different only by moving the position of the decoration.
The ED can be selectively turned on, and the primary coil and the secondary coil can be placed at positions where they can be placed close to each other at the same time. Many LEDs can be turned on simultaneously or selectively turned on, and its unexpectedness and variety of changes and LED
The combination of the beauty of the lighting and the excellent lighting effect.
