Abstract

There is provided a light emitting diode package, including a package body including a recess portion having a housing space and a lead frame mounted on the recess portion to be exposed; a light emitting diode chip mounted to be electrically connected to the lead frame; and a position indicator formed on the lead frame and guiding the mounting position of the light emitting diode chip.

Claims (25)

1. A light emitting diode package, comprising:

a package body including a recess portion having a housing space and a lead frame mounted on a bottom surface of the recess portion to be exposed, the lead frame having a top surface and a bottom surface opposite to the top surface and facing the bottom surface of the recess portion;

a light emitting diode chip mounted on the top surface of the lead frame to be electrically connected to the lead frame, such that a bottom surface of the light emitting diode chip faces the top surface of the lead frame, the top surface of the lead frame having a predetermined mounting area corresponding to the bottom surface of the light emitting diode chip; and

a position indictor formed on the top surface of the lead frame at a mounting position on the circumference of the predetermined mounting area,

wherein the position indicator is spaced apart from a side of the recess portion with a width length of about 200 μm to 270 μm.

2. The light emitting diode package of claim 1 , wherein the position indicator comprises patterns formed to be indented inward on the lead frame.

3. The light emitting diode package of claim 1 , wherein the position indicator comprises:

a first pattern formed to be spaced about 200 μm to 270 μm apart from the side of the recess portion in a width direction thereof; and

a second pattern formed to be spaced about 600 μm to 700 μm apart from the first pattern.

4. The light emitting diode package of claim 1 , wherein the position indicator comprises:

a first pattern formed to be spaced about 200 μm to 270 μm apart from the side of the recess portion in a width direction thereof; and

a second pattern formed to be spaced about 50 μm to 100 μm apart from a side of the recess portion in a length direction thereof.

5. A light emitting diode package, comprising:

a package body including a recess portion having a housing space and a lead frame mounted on a bottom surface of the recess portion to be exposed, the lead frame having a top surface and a bottom surface opposite to the top surface and facing the bottom surface of the recess portion;

a light emitting diode chip mounted on the top surface of the lead frame to be electrically connected to the lead frame, such that a bottom surface of the light emitting diode chip faces the top surface of the lead frame, the top surface of the lead frame having a predetermined mounting area corresponding to the bottom surface of the light diode chip; and

a position indicator formed on the top surface of the lead frame at a mounting position on the circumference of the predetermined mounting area,

wherein the position indicator comprises:

a first pattern formed to be spaced about 200 μm to 270 μm apart from a side of the recess portion in a width direction thereof and spaced about 50 μm to 100 μm apart from a side of the recess portion in a length direction thereof;

a second pattern formed to be horizontally disposed about 600 μm to 700 μm from the first pattern in a length direction thereof;

a third pattern formed to be horizontally disposed about 200 μm to 250 μm from the first pattern in a width direction thereof; and

a fourth pattern formed to be horizontally disposed about 600 μm to 700 μm from the third pattern in a length direction thereof.

6. The light emitting diode package of claim 1 , further comprising: a zener mounted on the top surface of the lead frame and configured to prevent static electricity such that a bottom surface of the zener faces the top surface of the lead frame.

7. The light emitting diode package of claim 6 , wherein:

the top surface of the lead frame has a predetermined zener mounting area corresponding to the bottom surface of the zener, and

the position indicator includes a zener indicating pattern formed on the top surface of the lead frame at a zener mounting position on the circumference of the predetermined zener mounting area.
