An LED lighting device with a heat dissipating structure is disclosed. The lighting device includes a lamp base coupled with a top cover to form an accommodating space for accommodating a first heat dissipating module and a second heat dissipating module. The first heat dissipating module includes a first heat-conducting plate, a first heat pipe and a first heat dissipater. An LED lighting module is connected with the first heat-conducting plate, in which an evaporator section of the first heat pipe is disposed thereon. The first heat dissipater is arranged on a condenser section of the first heat pipe, and the second heat dissipating module includes a second heat-conducting plate and a second heat pipe. The second heat-conducting plate paralleling to the first heat-conducting plate is connected with the LED lighting module. An evaporator section of the second heat pipe is disposed on the second heat-conducting plate, and whose condenser section is connected with an inner surface of the top cover. Whereby, the heat generated from the LED lighting module can be dissipated uniformly and rapidly.
