Abstract
A light emitting diode adapted to improve light efficiency is disclosed. The light emitting diode includes: a light emitting chip; a first lead frame loaded with the light emitting chip and configured to include first through fourth tilted surfaces which expand outwardly from a region loaded with the light emitting diode, the first and second tilted surfaces being arranged symmetrically with each other in a first direction and the third and fourth tilted surfaces being symmetrical with each other in a second direction perpendicular to the first direction; a second lead frame separated by a fixed distance from the first lead frame; first and second wires configured to connect the first and second lead frames to the light emitting chip, respectively; and a mold frame configured to encompass the first and second lead frames and to include first and second reflection surfaces, which are arranged symmetrically with each other in the first direction of the first lead frame, and third and fourth reflection surfaces which are arranged symmetrically with each other in the second direction of the first lead frame.
