Abstract

A light emitting device according to an embodiment includes: a body including a cavity formed with a stepped section; an electrode of which one end is disposed on the stepped section and the other end is disposed outside of the body; a heat sink including a main frame and a sub frame, wherein the sub frame includes a slope and a portion of the heat sink is disposed outside of the body; and a light emitting diode disposed on the heat sink.

Claims (25)

1. A light emitting device, comprising:

a body including a cavity formed with a stepped section;

an electrode of which one end is disposed on the stepped section and the other end is disposed outside of the body;

a heat sink including a main frame and a sub frame, wherein the sub frame includes a slope and a portion of the heat sink is disposed outside of the body; and

a light emitting diode disposed on the heat sink.

2. The light emitting device of claim 1 , wherein the stepped section is formed on the inner surface of the body forming the cavity.

3. The light emitting device of claim 1 , wherein the slope of the sub frame is inclined upwards from a bottom surface of the body.

4. The light emitting device of claim 1 , wherein the heat sink includes a metallic material or a resin material.

5. The light emitting device of claim 1 , further comprising an encapsulant disposed in the cavity.

6. The light emitting device of claim 1 , wherein the encapsulant includes a phosphor material.

7. The light emitting device of claim 1 , wherein the portion of the heat sink is protruded from a bottom surface of the body.

8. The light emitting device of claim 1 , wherein the electrode includes a first surface and a second surface, and the first surface is disposed higher than the second surface.

9. The light emitting device of claim 1 , wherein the heat sink is coupled with the body.

10. A light unit, comprising:

a light emitting device comprising a body including a cavity formed with a stepped section, an electrode of which one end is disposed on the stepped section and the other end is disposed outside of the body, a heat sink including a main frame and a sub frame, wherein the sub frame includes a slope and a portion of the heat sink is disposed outside of the body, and a light emitting diode disposed on the heat sink;

a substrate disposed under the light emitting device, wherein at least the portion of the heat sink is disposed inside the substrate.

11. The light unit of claim 10 , wherein the substrate includes an insulation layer with a through-hole and a circuit pattern disposed on the insulation layer and at least the portion of the heat sink is inserted into the through-hole.

12. The light unit of claim 10 , wherein the substrate includes a metallic layer, an insulation layer disposed on the metallic layer and having a through-hole to expose the metallic layer, and a circuit pattern disposed on the insulation layer, and at least the portion of the heat sink is inserted into the through-hole to contact the metallic layer.

13. The light unit of claim 10 , wherein the stepped section is formed on the inner surface of the body forming the cavity.

14. The light unit of claim 10 , wherein the slope of the sub frame is inclined upwards from a bottom surface of the body.

15. The light unit of claim 10 , wherein the heat sink includes a metallic material or a resin material.

16. The light unit of claim 10 , further comprising an encapsulant disposed in the cavity.

17. The light unit of claim 10 , wherein the encapsulant includes a phosphor material.

18. The light unit of claim 10 , wherein the electrode includes a first surface and a second surface, and the first surface is disposed higher than the second surface.

19. The light unit of claim 10 , wherein the heat sink is coupled with the body.
