The present invention relates to an LED lighting device and, more particularly to an LED lighting device using an LED light source. The LED lighting device, including an air-cooling heat radiation part, comprises a heat plate which is in surface-contact with the inner side of a heat radiation body having heat radiation blades in all directions in order to effectively emit heat generated in a light source through a structure design increasing a heat radiation effect, thereby reducing production costs and securing production availability. To accomplish the purpose same as above, the LED lighting device according to the present invention comprises the LED light source; the heat plate which transmits heat by being connected with the light source; and a main body which has a receiving part in which the light source is received and embeds the heat plate. The main body is formed of a pair of divided heat radiation bodies having the heat radiation blades formed in all directions and the heat plate is embedded and combined to be in surface-contact between the divided heat radiation bodies. |
