Mold for light-emitting device package

1. A light-emitting device package mold comprising:

a convex unit, of which an inner circumference has a hemispherical shape;

a flat panel unit that forms a flat panel by extending from an edge of the convex unit;

a cylindrical unit extending in a vertical direction with respect to an upper surface of the flat panel unit; and

an injection hole and a discharge hole that penetrate through the convex unit, wherein the discharge hole extends in a direction substantially parallel to the flat panel unit.

2. The light-emitting device package mold of claim 1 , wherein the injection hole and the discharge hole located separate from the flat panel unit.

3. The light-emitting device package mold of claim 1 , wherein the injection hole and the discharge hole are respectively closer to the flat panel unit than a vertical middle point of the convex unit.

4. The light-emitting device package mold of claim 1 , wherein the light-emitting device package mold is formed of a transparent material.

5. The light-emitting device package mold of claim 1 , further comprising a protrusion unit that protrudes in a direction opposite to the extending direction of the cylindrical unit from a lower surface of the flat panel unit and surrounds an edge of the convex unit.

6. The light-emitting device package mold of claim 1 , wherein the discharge hole faces the injection hole in a horizontal direction with respect to the flat panel unit.

7. The light-emitting device package mold of claim 6 , further comprising an injection member that is connected to the injection hole and extends in a vertical direction.

8. The light-emitting device package mold of claim 6 , wherein the injection hole and the discharge hole are positioned to be separate from the flat panel unit.

9. The light-emitting device package mold of claim 6 , wherein the injection hole and the discharge hole are respectively closer to the flat panel unit than a vertical middle point of the convex unit.

10. The light-emitting device package mold of claim 6 , wherein the light-emitting device package mold is formed of a transparent material.

11. The light-emitting device package mold of claim 6 , further comprising a protrusion unit that protrudes in a direction opposite to the extending direction of the cylindrical unit from a lower surface of the flat panel unit and surrounds an edge of the convex unit.

12. A light-emitting device packaging molding device, comprising:

a light-emitting device package including a substrate, and a light-emitting device (LED) chip disposed on the substrate;

a protruding ring disposed on the substrate and circling around the LED chip at a predetermined distance from the LED chip; and

a light-emitting device package mold including:

a convex unit, of which an inner circumference has a hemispherical shape;

a flat panel unit by extending from an edge of the convex unit;

a cylindrical unit extending in a vertical direction with respect to an upper surface of the flat panel unit;

a protrusion unit that protrudes in a direction opposite to the extending direction of the cylindrical unit from the flat panel unit and surrounds an edge of the convex unit; and

an injection hole that penetrates through the convex unit,

wherein the protruding ring contacts with the protrusion unit to seal a space defined by the convex unit and the substrate.

13. The light-emitting device packaging molding device of claim 12 , wherein the protrusion unit has at least one opening.

14. The light-emitting device packaging molding device of claim 12 , wherein the at least one opening extends in a direction substantially parallel to the flat panel unit.

15. The light-emitting device packaging molding device of claim 12 , wherein the injection hole extends in the vertical direction, and an inner diameter of the injection hole increases in the vertical direction.

16. The light-emitting device packaging molding device of claim 12 , wherein the protruding ring forms a circular contact line with the protrusion unit.
