Light emitting diode (led) package and illuminating device including the same

A light-emitting diode (LED) package comprising:

• a package substrate comprising a first surface on which an LED chip is disposed;
• and
• a first external connection pad and a second external connection pad disposed on a second surface of the package substrate, the first external connection pad and the second external connection pad being electrically connected to the LED chip,
• wherein the first external connection pad comprises:
• a first side, a second side, a third side and a fourth side;
• a first corner connected to the first side and the third side, the first corner having having a round profile;
• a second corner connected to the first side and the fourth side, the second corner having a round profile;
• a third corner connected to the second side and the third side, the third corner having a round profile;
• and
• a fourth corner connected to the second side and the fourth side, the fourth corner having a round profile,
• wherein the first side and the second side extend in a first direction,
• wherein the third side and the fourth side extend in a second direction perpendicular to the first direction,
• wherein the first side and the second side are respectively longer than the third side and the fourth side,
• wherein the first corner is spaced farther from a center of the package substrate than the third corner, and
• wherein a radius of the first corner is larger than a radius of the third corner.
