An LED lamp includes a heat sink, a reflecting cup, a heat pipe and an LED. The heat sink includes fins cooperatively defining a receiving space therein. Each of the fins includes a plate-shaped main body and a flange extending rearward from a periphery side of the main body. The flanges are connected to each other to cooperatively form an annular supporting surface. The reflecting cup is received in the receiving space of the heat sink. The heat pipe includes an evaporating section located above the reflecting cup and a condensing section thermally connecting with the annular supporting surface of the heat sink. The LED is directly mounted on the evaporating section with a light emitting surface facing downwardly towards the reflecting cup. |
