    摘要： An exemplary embodiment discloses a light-emitting diode (LED) lamp including a heat sink including a first surface and a second surface, and a substrate including a first surface and a second surface. The substrate disposed on the heat sink and the first surface of the heat sink contacts the second surface of the substrate. The LED lamp also includes at least one first LED disposed on the first surface of the substrate and a transparent cover connected to the heat sink and spaced apart from the substrate. The second surface of the heat sink is adjacent to the first surface of the heat sink. The second surface of the heat sink extends toward the transparent cover. At the least an end point of the second surface of the heat sink is disposed over an outer region of edges of the substrate.
