A fluorescent lamp type LED lamp is provided to discharge the heat generated in an LED element and reduce power consumption by arranging the LED element inside a tube to discharge the heat. A plurality of radiation fins are protrusively formed in a longitudinal direction along an inner circumference of a cylindrical tube(20). A module(30) is fixed inside the tube. A plurality of LED elements is uniformly mounted on a PCB substrate(31). A control pattern and a resistance are arranged in the rear of the module. The PCB substrate is inserted between the heat radiation fin(27) protruded along the longitudinal direction of the inner side of the tube. A starter and a ballast are arranged in the end part of the PCB substrate. |
