Abstract

An LED patch for a skin care apparatus is provided. An LED patch for a skin care apparatus according to an exemplary example of the present invention comprises: a substrate part; a circuit pattern part formed in at least two layers on the substrate part; a light source part including one or more LEDs mounted on one surface of the substrate part; and a cover part configured to cover at least one surface of the substrate part.

First claim

The invention claimed is:

1. A light-emitting diode (LED) patch for a skin care apparatus, comprising:
a substrate part;
a circuit pattern part formed in at least two layers on the substrate part;
a light source part including one or more LEDs mounted directly on the circuit pattern part; and
a cover part configured to cover at least one surface of the substrate part,
wherein the circuit pattern part includes:
a first pattern formed directly on the substrate part, wherein the first pattern has a pattern shape; and
a second pattern having the same pattern shape and attached to one surface of the first pattern through a conductive adhesive layer,
wherein the first pattern is a printed pattern formed directly on the substrate part and configured to fill pores of the substrate part with a conductive material,
wherein the second pattern is stacked on one surface of the first pattern through the conductive adhesive layer so that it is located directly on an upper surface of the first pattern, and
wherein the first pattern and the second pattern secure conductive stability for the one or more LEDs by compensating for mutual short circuits.

2. The LED patch of claim 1 , wherein:
the printed pattern is formed by filling the pores formed in the substrate part with the conductive material; and
the second pattern is a conductive microfiber web in which a microfiber web is plated with a conductive material.

3. The LED patch of claim 1 , wherein:
the circuit pattern part includes a plurality of patterns which are not electrically connected to each other; and
the plurality of patterns are electrically connected to each other through the one or more LEDs mounted directly on the circuit pattern part.

4. The LED patch of claim 3 , wherein the plurality of patterns electrically connected to each other through the one or more LEDs are linear patterns or planar patterns having a predetermined area.

5. The LED patch of claim 1 , wherein:
the cover part includes a first cover member and a second cover member which are disposed on both surfaces of the substrate part, respectively, such that the first cover member covers the one or more LEDs; and
the first cover member covering the one or more LEDs is a light-transmitting member, and the second cover member is a translucent member or an opaque member.

6. The LED patch of claim 5 , wherein the first cover member includes a light diffusion material.

7. The LED patch of claim 1 , further comprising a support sheet having a plate shape which is disposed on a surface opposite to the one surface of the substrate part, on which the circuit pattern part is formed and supports the substrate part.

8. The LED patch of claim 7 , further comprising a heat dissipation sheet disposed on a surface of the support sheet.

9. The LED patch of claim 1 , further comprising a protective layer formed on an exposed surface of the cover part.

10. The LED patch of claim 1 , further comprising one or more temperature sensors.

11. The LED patch of claim 1 , further comprising a heat generation part configured to generate heat when power is applied.

12. The LED patch of claim 11 , wherein the heat generation part includes:
a base substrate having a plate shape;
a lead electrode part formed along an edge of one surface of the base substrate and including lead electrodes which are not physically connected to each other;
a branch electrode part including branch electrodes which are not electrically connected to each other and which each extend from the lead electrode part such that partial lengths of the branch electrodes face each other; and
a conductive heat generation material which has a predetermined area, is formed to be located at overlapping portions of the branch electrodes, and generates heat while electrically conducting the branch electrodes when power is supplied.

13. The LED patch of claim 12 , wherein:
the heat generation part includes a plurality of branch electrode parts spaced apart from each other by a predetermined interval along a length direction of the lead electrode part, and a plurality of conductive heat generation materials provided at each of the plurality of branch electrode parts; and
the plurality of branch electrode parts and the plurality of conductive heat generation materials are disposed to be located at positions that do not overlap the plurality of LEDs.

14. The LED patch of claim 12 , wherein:
the base substrate includes a film member having an insulating property, and a porous substrate stacked on one surface of the film member; and
the lead electrode part and the branch electrode part are formed on the porous substrate.

15. The LED patch of claim 1 , further comprising a connection cable configured to supply power supplied from an outside toward the light source part.

16. The LED patch of claim 15 , wherein the connection cable is electrically connected to the light source part through a circuit board disposed such that a partial area thereof overlaps the substrate part.

17. The LED patch of claim 15 , wherein the connection cable includes a connected port to be connected provided at one end thereof so as to be connected to an external power supply device.

18. A skin care apparatus comprising:
at least one LED patch for a skin care apparatus of claim 1 ;
a connection part configured to electrically connect an external power supply device and a connection cable of the at least one LED patch for a skin care apparatus to each other; and
a control part provided in the connection part to control overall driving of the light source part.

19. The skin care apparatus of claim 18 , wherein the external power supply device is a portable electronic device or an auxiliary battery.
