Abstract

Disclosed herein is a slim LED package. The slim LED package includes first and second lead frames separated from each other, a chip mounting recess formed on one upper surface region of the first lead frame by reducing a thickness of the one upper surface region below other upper surface regions of the first lead frame, an LED chip mounted on a bottom surface of the chip mounting recess and connected with the second lead frame via a bonding wire, and a transparent encapsulation material protecting the LED chip while supporting the first and second lead frames.

Claims (34)

1. A light emitting diode (LED) package, comprising:

a first lead frame and a second lead frame separated from each other;

an LED chip disposed on the first lead frame and electrically connected with the second lead frame; and

a resin covering at least portions of surfaces of the first and second lead frames,

wherein:

each of the first and second lead frames comprises:

a first side facing the other lead frame and a second side opposite the first side;

a first groove disposed on a lower surface thereof and adjacent the first side;

a second groove disposed on the lower surface thereof and adjacent the second side; and

a depth of the first groove is equal to a depth of the second groove.

2. The LED package of claim 1 , wherein the first groove is disposed along the first side of at least one of the first and second lead frames.

3. The LED package of claim 1 , wherein at least a portion of the lower surface of at least one of the first and second lead frames is not covered by the resin.

4. The LED package of claim 3 , wherein at least a portion of the second side of at least one of the first and second lead frames is not covered by the resin.

5. The LED package of claim 1 , wherein at least one of the first and second lead frames comprises at least one protrusion disposed on at least one side thereof.

6. The LED package of claim 5 , wherein:

at least one of the first and second lead frames further comprises a third side and a fourth side opposite the third side, and the third and fourth sides are disposed between the first and second sides; and

the protrusion extends from at least one of the third side and the fourth side.

7. The LED package of claim 6 , wherein the protrusion is disposed on an imaginary line extending from the third side to the fourth side.

8. The LED package of claim 7 , wherein the imaginary line is substantially perpendicular to the third side.

9. The LED package of claim 1 , wherein at least one of the first groove and the second groove is formed by reducing a thickness of a predetermined region of the lower surface of at least one of the first and second lead frames.

10. The LED package of claim 1 , wherein the resin fills at least a portion of the first groove.

11. The LED package of claim 1 , wherein an area of an upper surface of the first lead frame is greater than an area of the lower surface of the first lead frame.

12. The LED package of claim 1 , wherein the first groove and the second groove in each of the first and second lead frames extend in a direction perpendicular to an imaginary line which extends from the first side to the second side.

13. The LED package of claim 12 , wherein the imaginary line is substantially parallel to the first side.

14. A light emitting diode (LED) package, comprising:

a first lead frame and a second lead frame separated from each other;

an LED chip disposed on the first lead frame and electrically connected with the second lead frame; and

a resin material covering at least portions of surfaces of the first and second lead frames,

wherein:

the first lead frame and the second lead frame comprise first sides facing each other; and

each of the first and second lead frames comprises:

resin holding components disposed on the first side, the resin holding components comprising a slant part configured to rigidly hold the resin material;

a second side opposite the first side; and

an opening disposed on the lower surface thereof and adjacent the second side.
