Abstract

The sticker-shape light-emitting device using a near field communication system includes: a main body having a panel shape; an induction coil that is disposed on a front surface of the main body as a coil shape and converts an electromagnetic wave to electricity by an electromagnetic induction phenomenon, wherein the electromagnetic wave is emitted from a terminal that can have non-contact communication; a light-emitting diode that emits light by electrical energy generated from the induction coil; and an adhesion unit that is disposed on a rear surface of the main body and on which an adhesive is coated so that the main body is attached to a specific surface of an object.

Claims

1. A sticker-shape light-emitting device using a near field communication system comprises:

a main body having a panel shape;

an induction coil that is disposed on a front surface of the main body as a coil shape and converts an electromagnetic wave to electricity by an electromagnetic induction phenomenon, wherein the electromagnetic wave is emitted from a terminal that can have non-contact communication;

a light-emitting diode that emits light by electrical energy generated from the induction coil; and

an adhesion unit that is disposed on a rear surface of the main body and on which an adhesive is coated so that the main body is attached to a specific surface of an object.

2. The sticker-shape light-emitting device of claim 1, wherein the light-emitting device further comprises a film-shape display unit that is disposed to cover the light-emitting diode and illuminates light emitted from the light-emitting diode to the outside, wherein the display unit comprises a transparent or semitransparent part.

3. The sticker-shape light-emitting device of claim 1, wherein the adhesion unit comprises a white sheet that is attached to the rear surface of the main body, and a protection sheet that is attached to a rear surface of the white sheet.

4. The sticker-shape light-emitting device of claim 3, wherein an adhesive is coated on a surface or both surfaces of the protection sheet.

5. The sticker-shape light-emitting device of claim 1, wherein the induction coil and the light-emitting diode are mounted on a single flexible printed circuit board.

6. The sticker-shape light-emitting device of claim 1, wherein the main body has a degree of flexibility that is bendable by a force of a human finger.

7. The sticker-shape light-emitting device of claim 2, wherein the main body has a degree of flexibility that is bendable by a force of a human finger.

8. The sticker-shape light-emitting device of claim 3, wherein the main body has a degree of flexibility that is bendable by a force of a human finger.

9. The sticker-shape light-emitting device of claim 4, wherein the main body has a degree of flexibility that is bendable by a force of a human finger.

10. The sticker-shape light-emitting device of claim 5, wherein the main body has a degree of flexibility that is bendable by a force of a human finger.
