An LED lamp includes a heat dissipation part, an optical part and an electric part. The optical part includes an LED module attached to a heat dissipation member of the heat dissipation part and an envelope covering the LED module. The electric part includes a casing, a circuit board and a lamp cap. The casing includes a bottom plate and an annular sidewall extending from a periphery of the bottom plate to connect with the heat dissipation part and the optical part. The lamp cap includes an electric shell and an electric pole axially inserted in the electric shell. The lamp cap is rotatablely connected to the casing via the electric pole. The electric pole is fixedly connected to and electrically insulated from the electric shell. An orientation-adjusting structure is provided between the casing and the lamp cap for adjusting the illumination direction of the LED lamp. |
