Abstract

A light emitting device package according to embodiments comprises: a package body; a lead frame on the package body; a light emitting device supported by the package body and electrically connected with the lead frame; a filling material surrounding the light emitting device; and a phosphor layer comprising phosphors on the filling material.

Claims (55)

1. A light emitting device package, comprising:

a metal;

a substrate comprising a first portion disposed along a horizontal direction and a second portion disposed along a vertical direction and surrounding and contacting side surfaces of the metal;

an electrode on the substrate;

a light emitting device on the substrate;

a phosphor layer surrounding the light emitting device; and

a lens covering the phosphor layer,

wherein a top surface of the first portion of the substrate contacts a bottom surface of the electrode and a bottom surface of the first portion of the substrate contacts a top surface of the metal,

wherein the substrate comprises a bottom recess under the light emitting device,

wherein the metal is disposed in the bottom recess such that the metal is in contact with both the first portion of the substrate and the second portion of the substrate, and

wherein a lateral width of the bottom recess is greater than that of the light emitting device.

2. The light emitting device package according to claim 1 , wherein the top surface of the first portion has a recess.

3. The light emitting device package according to claim 2 , wherein the recess of the first portion has a size greater than a size of the light emitting device.

4. The light emitting device package according to claim 2 , wherein the recess of the first portion has a width smaller than a width of the metal.

5. The light emitting device package according to claim 2 , wherein an entire region of the first portion corresponding to a width of the recess has the same thickness.

6. The light emitting device package according to claim 2 , wherein the second portion of the substrate has a thickness greater than a thickness of the first portion of the substrate.

7. The light emitting device package according to claim 2 , wherein the electrode comprises first and second electrodes connected to the light emitting device.

8. The light emitting device package according to claim 7 , wherein the first and second electrodes are disposed in the recess of the first portion.

9. The light emitting device package according to claim 2 , wherein the light emitting device is disposed in the recess of the first portion.

10. The light emitting device package according to claim 2 , wherein the lens covers at least the recess of the first portion.

11. The light emitting device package according to claim 1 , wherein the phosphor layer contacts a top surface and side surfaces of the light emitting device.

12. The light emitting device package according to claim 1 , wherein the lens has a dome shape.

13. The light emitting device package according to claim 1 , wherein the electrode and the metal each vertically overlap with the first portion of the substrate therebetween.

14. The light emitting device package according to claim 1 , wherein the metal has a thickness greater than a thickness of the light emitting device.

15. The light emitting device package according to claim 1 , wherein the first portion of the substrate is disposed under the light emitting device, and

wherein an outer most side surface of the first portion of the substrate is expanded over an outer most side surface of lens.

16. A light emitting device package, comprising:

a metal;

a substrate comprising a first portion disposed along a horizontal direction and a second portion disposed along a vertical direction and surrounding and contacting side surfaces of the metal;

an electrode on the substrate;

a light emitting device on the substrate;

a phosphor layer surrounding the light emitting device; and

a lens covering the phosphor layer,

wherein the first portion has a top surface having a recess,

wherein at least one of the electrode and the light emitting device is disposed in the recess of the first portion,

wherein the top surface of the first portion of the substrate contacts a bottom surface of the electrode and a bottom surface of the first portion of the substrate contacts a top surface of the metal,

wherein the substrate comprises a bottom recess under the light emitting device,

wherein the metal is disposed in the bottom recess such that the metal is in contact with both the first portion of the substrate and the second portion of the substrate, and

wherein a lateral width of the bottom recess is greater than that of the light emitting device.

17. The light emitting device package according to claim 16 , wherein the metal has a thickness greater than a thickness of the first portion corresponding to the recess.

18. The light emitting device package according to claim 16 , further comprising a reflective layer on the electrode,

wherein the reflective layer is disposed under the light emitting device.

19. A light emitting device package, comprising:

a metal;

a substrate comprising a first portion disposed along a horizontal direction and a second portion disposed along a vertical direction and surrounding and contacting side surfaces of the metal;

first and second electrodes spaced apart from each other on the substrate;

a light emitting device connected to the first and second electrodes;

a phosphor layer surrounding the light emitting device; and

a lens covering the phosphor layer,

wherein a top surface of the first portion of the substrate contacts a bottom surface of the electrode and a bottom surface of the first portion of the substrate contacts a top surface of the metal,

wherein the metal has a thickness greater than a thickness of the first portion of the substrate,

wherein the substrate comprises a bottom recess under the light emitting device,

wherein the metal is disposed in the bottom recess such that the metal is in contact with both the first portion of the substrate and the second portion of the substrate, and

wherein a lateral width of the bottom recess is greater than that of the light emitting device.

20. The light emitting device package according to claim 19 , wherein the phosphor layer contacts the electrode.
