The utility model provides a light emitting diode (LED) lighting device. The LED lighting device can improve the heat dissipation effect of LEDs, protect a heat dissipation part and an electrical component and improve appearance quality after being installed. The LED lighting device (1) comprises a plurality of LEDs (21) as a light source, a cover (22), a substrate (23) which is provided with the LEDs (21), a heat dissipation part (24) which are installed on the face, on one side opposite to the face which is provided with the LEDs (21), of the substrate (23), a device body (31), a protruding part (32) which protrudes from the back portion (31a) of the device body (31) and a roof plate (33) which is fixed at the front end of the protruding part (32). The periphery of the heat dissipation part (24) is surrounded by the protruding part (32) and the roof plate (33). |
