ABSTRACT:
A light emitting device includes a metal base, an electrical circuit layer provided at an upper side of the metal base for providing a conductive path, a light emitting device mounted in a second region having a smaller thickness than a first region on the metal base, an insulating layer sandwiched between the metal base and the electrical circuit layer, an electrode layer provided at an upper side of the electrical circuit layer, and a wire for electrically connecting the electrode layer and the light emitting device. The light emitting device package has improved light emission efficiency since the light emitting device is placed on a small thickness portion of the metal base.
