1. A light emitting apparatus comprising:
a housing including conductive leads configured to receive a current;
a light emitting diode, the light emitting diode comprising:
an n-type nitride semiconductor layer having a first thickness;
an active layer located on the n-type nitride semiconductor layer and configured to emit a light; and
a p-type nitride semiconductor layer located on the active layer and having a second thickness; and
a mold covering the light emitting diode,
wherein the first thickness is different from the second thickness; and
wherein the light includes a first x color coordinate and a first y color coordinate at a first current and a second x color coordinate and a second y color coordinate at a second current, and the first x color coordinate is different from the second x color coordinate.
