Claim:
1. A light-emitting diode (LED) package, comprising: a lead frame including a die pad and at least one electrode, the at least one electrode being isolated from the die pad by at least one gap, the die pad including first and second trenches located within the opening of the housing, both ends of each of the first and second trenches opening into the at least one gap; a first insulator partially encapsulating the lead frame such that a portion of an upper surface of the die pad and a portion of the at least one electrode are exposed from the first insulator and the at least one gap and the first and second trenches are at least partially filled by the first insulator; an LED chip disposed on the exposed portion of the upper surface of the die pad and located between the first and second trenches; wherein the die pad has a lower surface such that the lower surface is exposed to an exterior of the package, the exposed lower surface being contiguous; wherein the die pad includes at least one upper surface protrusion which is oriented towards the exterior of the package and is partially encapsulated by the first insulator; and wherein the at least one electrode has a lower surface and an upper surface such the lower surface is smaller than the upper surface and the at least one electrode has an upper surface protrusion which is oriented towards an interior of the package wherein the upper surface protrusion has a lower surface which is smaller than the at least one electrode lower surface.
