Abstract

(57) [Summary] [Problem] It can be used as it is or can be used by attaching it to the bottom of a transparent cup or the like, and it is built in only when it is placed close to and opposed to the primary coil through which a high-frequency current has flowed A glowing sheet is provided in which the LEDs light up and glow, and the LEDs turn off when removed from the primary coil. SOLUTION: A secondary coil and at least one LED connected to the secondary coil are provided in a transparent or translucent sheet-like member, and the secondary coil is close to and opposed to the primary coil through which a high-frequency current has flowed. The LED is illuminated when placed. Further, the sheet-like member is made of an adhesive elastomer. Alternatively, it is characterized in that a transparent or translucent double-sided adhesive tape is attached to one surface of the sheet-like member.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 This invention relates to a glowing sheet that can be used as a glowing coaster, vase mat, wall or shelf as it is, or can be used as a glowing cup or a glowing vase on the bottom of a cup or vase.

[0002]

[Problems to be solved by the invention]

 The purpose of this invention is to use the LED as it can be used as it is or can be used by attaching it to the bottom of a transparent cup or the like, and only when it is placed close to and opposed to the primary coil through which a high-frequency current flows. The object is to provide a glowing sheet that lights up and glows and the LEDs go off when the primary coil is removed.

[0003]

[Means for Solving the Problems]

 In order to solve the above-mentioned object, the luminous sheet of the present invention is provided with a secondary coil and at least one LED connected to the secondary coil in a transparent or translucent sheet-like member, and a high-frequency current. The LED is turned on when the secondary coil is disposed close to and opposed to the primary coil through which the current flows. Further, the sheet-shaped member is made of an adhesive elastomer. Alternatively, a transparent or translucent double-sided adhesive tape is attached to one surface of the sheet-shaped member.

[Embodiment of the invention]

 FIG. 1 and FIG. 2 are perspective views of the glowing sheet of the present invention and the power supply device thereof. The shining sheet 1 is a sheet in which a secondary coil 3 and four chip-shaped LEDs 4 connected between both terminals are embedded in a thin elastomer sheet 2 having a transparent or translucent adhesive property. is there. The power supply device includes an inverter 5 for converting a commercial power supply into a high-frequency current and two primary coils 6 connected in series to an output of the inverter 5. The primary coils 6 are placed at different positions in the sheet-like member 7. It was buried. The number of turns of the primary coil 6 is about one to several times, and the number of turns of the secondary coil 3 is about several to tens of times.

Now, if the shining sheet 1 is placed on a sheet-like member 7 in which the primary coil 6 is buried, and the secondary coil 3 is disposed so as to be in close proximity to one of the primary coils 6, A current proportional to the reciprocal of the winding ratio flows through the secondary coil 3 by electromagnetic induction, and the four LEDs 4 are turned on. When the position of the shining sheet 1 is slightly shifted and the secondary coil 3 is moved to a position where the secondary coil 3 is separated from the primary coil 6, the LED 4 is turned off.

[0006] The shiny sheet 1 is attached to the bottom of a cup or a vase by using the adhesive property of the elastomer, and is placed on a sheet-like member 7 previously provided on a table or a counter to shift the position. The LED 4 suddenly turns on when the secondary coil 3 and the primary coil 6 are arranged opposite to each other, and turns off again when the secondary coil 3 is displaced from that position. Therefore, it is more interesting and surprising that the sheet-like member 7 in which the primary coil 6 is embedded is made opaque.

In the above-described embodiment, the shining sheet 1 is made of an adhesive elastomer, but is made of ordinary plastic having no adhesive, and a double-sided adhesive tape is stuck on one surface thereof. Is also good. The number of LEDs 4 provided in the glowing sheet 1 is not limited to four, and any number of LEDs may be provided as needed, and LEDs having different emission colors may be used in combination. Further, instead of providing the primary coils 6 in the sheet-shaped member 7, the primary coils 6 can be directly buried in the upper surface of a table or the like, and the number thereof is not limited to two. Furthermore, the shining sheet 1 can be used as it is as a coaster or vase bed, or the sheet-like member 7 can be provided on a wall or shelf provided in advance and used as a decoration.

[0008]

[Effect of the invention]

 As described above, the glowing sheet of this invention is designed so that the built-in LED lights and glows only when it is placed in close proximity to the primary coil to which the high-frequency current flows, and turns off when it is separated from the primary coil. The LED lights up only when it is moved to a specific position, so it can be used as a glowing coaster, vase mat, wall or shelf decoration, or a transparent cup or vase bottom. It can also be used as a glowing cup or a glowing vase when pasted on, and has excellent effects as amusement goods.
