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 solve the above-mentioned object, a glowing decorative object according to the present invention is provided with a plurality of secondary coils on a bottom surface or a back surface of an object which is at least partially transparent or translucent. At least two LEDs are connected to each secondary coil in anti-parallel, and
Provided ED transparent or translucent part of the object, wherein
A plurality of primary coils in which a high-frequency current is applied to a member on which an object is mounted or a wall surface on the rear side thereof are provided at positions where the plurality of secondary coils can be simultaneously arranged in close proximity to each other.

[0004]

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a perspective view of a shining decoration according to the present invention. The glowing decoration 1 has two secondary coils 3 </ b> A on the bottom surface of the (opaque) base end of an object 2 that is at least partially transparent (e.g., the entire upper side excluding the base end). Buried a little away from 3B,
Two (for example, red and blue) chip-shaped LEDs 4A and 4B are connected in anti-parallel between both terminals of each secondary coil, and the LEDs 4A and 4B are made transparent or translucent on the upper side of the object 2. It is arranged in the part where it is. The material of the object 2 is glass, plastic, ceramic,
Any other material that can be formed at least partially transparent or translucent (to the extent that the LED looks dim when lit), and other materials (opaque metal, stone, wood, etc.) It may be a combination with a substance.

FIG. 2 is a perspective view of a power supply device 5 for supplying power to a glowing decoration without connection. The power supply device 5
An inverter 6 converts a commercial power supply or a battery power supply into a high-frequency current, and two primary coils 7A and 7B connected in series to the output thereof.
7B is buried in a thin sheet member 8 at the same interval as the secondary coils 3A and 3B. For this reason, the decoration 1 which shines on the sheet-shaped member 8 can be arranged so that the secondary coils 3A and 3B are opposed to the primary coils 7A and 7B, respectively.
It is also possible to dispose only one of 3B opposite primary coil 7A or 7B. At that time, a current proportional to the reciprocal of the winding ratio flows from the primary coil to the opposing secondary coil by electromagnetic induction, and the LE connected to the secondary coil
D4A and 4B are turned on.

Now, the sheet-like member 8 is laid on an ornamental shelf or the like, and the shining decoration 1 is placed thereon. When they are arranged facing each other,
LED 4A connected to secondary coil 3A and secondary coil 3
Both of the LEDs 4B connected to B light up. When the decoration 1 shining from this position is moved to the right so that the secondary coil 3A is arranged to face the primary coil 7B on the right, only the LED 4A connected to the secondary coil 3A is turned on.
Conversely, the shining decoration 1 is moved to the left, and the secondary coil 3 is moved.
B is arranged to face the primary coil 7A and LE
Only D4B lights up.

[0007] In the above embodiment, the primary coil of the power supply device is provided in a thin sheet-like member. However, the primary coil 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. Furthermore, the number of secondary coils provided in the shining decoration is not limited to two, and may be three or more. Also, the number of LEDs connected to each secondary coil is not limited to two but may be provided as many as necessary. You may.

Further, in the above embodiment, two secondary coils are provided on the bottom surface of the illuminated decoration, but they may be provided on the back surface of the illuminated decoration. 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.

[0009]

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 a display cabinet, and a plurality of primary coils are respectively connected to a plurality of secondary coils. At the same time, it is possible to light up many built-in LEDs simultaneously or selectively by simply moving the position of the shining decoration, by providing it in a position where it can be placed in close proximity opposition. The variety of the change and the beauty of the lighting of the LED combine to provide an excellent decorative effect.
