Abstract

Provided is a circuit board including: a supporting substrate; light emitting elements mounted to the supporting substrate; a through hole passing through the supporting substrate; and a connector inserted into the through hole and for supplying an electric current to the light emitting elements.

Claims

1. A circuit board, comprising:

a supporting substrate;

light emitting elements mounted to the supporting substrate;

a through hole passing through the supporting substrate; and

a connector inserted into the through hole and for supplying an electric current to the light emitting elements.

2. The circuit board of claim 1, wherein the light emitting elements are plural in number, and the through hole is formed at a position corresponding to a spaced portion between the light emitting elements.

3. The circuit board of claim 1, wherein the through hole is formed at a position corresponding to a lower side of the light emitting elements.

4. The circuit board of claim 1, wherein the supporting substrate comprises a first region and a second region extending to be bent from the first region, and the through hole is formed in at least one of the first region and the second region.

5. The circuit board of claim 4, wherein the light emitting elements are mounted to one surface of the first region of the supporting substrate, and the circuit board further comprises a pad portion having pad wirings connected to the light emitting elements on one surface of the first region;

and a string portion having string wirings for transmitting electrical signals to the light emitting elements in the first region or the second region.

6. The circuit board of claim 5, further comprising a bending hole formed in a bending portion between the first region and the second region.

7. The circuit board of claim 6, wherein the connector is mounted to the second region, and the string portion has the string wirings formed on another surface opposite to the one surface of the first region so as to be connected to the pad wirings through the bending hole.

8. A lighting device, comprising:

a circuit board of claim 1; and

an outer housing including an external through hole corresponding to a through hole of the circuit board.

9. A circuit board, comprising:

a supporting substrate;

light emitting elements mounted to the supporting substrate; and

a through hole through which the supporting substrate passes, and into which a connector for supplying currents to the light emitting elements is inserted.

10. The circuit board of claim 9, wherein the light emitting elements are plural in number, and the through hole is formed at a position corresponding to a spaced portion between the light emitting elements.

11. The circuit board of claim 9, wherein the through hole is formed at a position corresponding to a lower side of the light emitting elements.

12. The circuit board of claim 9, wherein the supporting substrate comprises a first region and a second region extending to be bent from the first region, and the through hole is formed in at least one of the first region and the second region.

13. The circuit board of claim 12, wherein the light emitting elements are mounted to one surface of the first region, and the circuit board further comprises a pad portion having pad wirings connected to the light emitting elements on the one surface of the first region, and a string portion having string wirings for transmitting electrical signals to the light emitting elements in the first region or the second region.

14. The circuit board of claim 13, further comprising a bending hole formed in a bending portion between the first region and the second region.

15. The circuit board of claim 14, wherein the connector is mounted to the second region, and the string portion has string wirings formed on another surface opposite to the one surface of the first region so as to be connected to the pad wirings through the bending hole.
