PURPOSE: An LED lighting device is provided to increase the heat radiation efficiency of an LED module by emitting internal heat to the outside while circulating upward external air in the lower part of the LED module. CONSTITUTION: An LED lighting device comprises a socket part (10), an LED module (20), multiple connection parts (30), and a blowing unit. The socket part is coupled to a socket. The LED module has multiple LEDs. The connection parts connect the socket part and the LED module. The blowing unit is installed on the top of the connection parts to emit heat generated when the LED module emits light and blows air to the LED module. |
