Abstract

Disclosed is an LED package. The LED package includes a package body, a semiconductor light emitting device on the package body and at least one of frames on the package body. At least one of the frames includes a bottom frame on the package body, and at least two sidewall frames extending from the bottom frame and inclined with respect to the bottom frame.

Claims (31)

1. A light emitting diode package comprising:

a package body;

a semiconductor light emitting device on the package body; and

a plurality of frames on the package body,

wherein at least one of the plurality of frames comprises a bottom frame on the package body, and at least two sidewall frames extend from the bottom frame and are inclined with respect to the bottom frame,

wherein at least one of the sidewall frames is inclined at an angle of about 15° to about 30° with respect to an axis perpendicular to the bottom frame, and

wherein at least two of the plurality of frames are electrically separated from each other.

2. The light emitting diode package according to claim 1 , wherein an interval between the at least two sidewall frames of at least one of the plurality of frames is about 420 μm to about 850 μm.

3. The light emitting diode package according to claim 1 , wherein a height of the sidewall frame is in the range of about 250 μm to about 700 μm.

4. The light emitting diode package according to claim 1 , wherein the bottom frame has a width of about 300 μm to about 450 μm.

5. The light emitting diode package according to claim 1 , wherein the bottom frame has a thickness of about 20 μm to about 300 μm.

6. The light emitting diode package according to claim 1 , wherein an internal angle between the at least two sidewall frames is about 30° to about 60°.

7. The light emitting diode package according to claim 1 , wherein the package body has a height of about 1 mm or less.

8. The light emitting diode package according to claim 1 , wherein at least one of the plurality of frames comprises a U-shaped metal plate.

9. The light emitting diode package according to claim 8 , wherein a reflective material is plated on surfaces of the U-shaped metal plates.

10. The light emitting diode package according to claim 1 , wherein the at least two sidewall frames are inclined at the predetermined angle and have a hemispherical shape.

11. The light emitting diode package according to claim 1 , wherein at least one of the plurality of frames is extended to an outer surface of the package body to function as an electrode.

12. The light emitting diode package according to claim 1 , wherein the semiconductor light emitting device is mounted on the bottom frame.

13. A light emitting diode package comprising:

a package body;

a semiconductor light emitting device on the package body; and

a plurality of frames on the package body,

wherein at least one of the plurality of frames comprises a bottom frame on the package body, and at least two sidewall frames extend from the bottom frame and are inclined with respect to the bottom frame, and

wherein the package body comprises a partition separating at least two of the plurality of frames from each other.

14. The light emitting diode package according to claim 1 , wherein the at least two sidewall frames are embedded in a cavity.

15. The light emitting diode package according to claim 14 , wherein the cavity comprises a depth of about 50 μm to about 700 μm.

16. The light emitting diode package according to claim 1 , wherein at least two of the plurality of frames comprise the bottom frame and the at least two sidewall frames.

17. The light emitting diode package according to claim 1 , wherein the plurality of frames comprise a plurality of reflective frames.

18. The light emitting diode package according to claim 1 , wherein the plurality of frames comprise one selected from the group consisting of Fe, Sn, Cr, Zn, Ni, Al, Ag, Au, and Cu and an alloy thereof.

19. The light emitting diode package according to claim 13 , wherein at least one of the sidewall frames is inclined at an angle of about 15° to about 30° with respect to an axis perpendicular to the bottom frame.

20. The light emitting diode package according to claim 19 , wherein an internal angle between the at least two sidewall frames is about 30° to about 60°.
