Abstract

A leadframe that is configured to be used with an electronic device, e.g., light emitting diode (LED), includes a heat sink supporting ring for supporting a heat sink. An outer frame is spaced apart from the heat sink supporting ring, and encloses the heat sink supporting ring. At least one supporting lead connects the heat sink supporting ring and the outer frame. A separated lead is extended from the outer frame toward the heat sink supporting ring, and is spaced apart from the heat sink supporting ring. A package body that may be formed by an injection molding after a heat sink is inserted into the leadframe.
