Abstract:
A lighting apparatus includes a light emitting diode, in which the light emitting diode includes an n-type nitride semiconductor layer, an active layer located on the n-type nitride semiconductor layer, and a p-type nitride semiconductor layer located on the active layer. The light emitting diode emits light that varies from yellow light to white light depending on an driving current.
