The present invention relates to an LED fluorescent lamp using far-infrared radiation without a heat sink. According to the present invention, a circuit is formed by peeling the copper foil layers on both sides of the non-metal double-sided PCB substrate. The area of the copper foil layer area on which LEDs are installed in series is maximized. The circuit components are mounted on the outside of the PCB, and the connection circuit is formed on a portion of the substrate surface in which the LEDs are not mounted. The LED fluorescent Lamp utilizes infrared emissivity to provide excellent heat dissipation even though a heat sink is not attached. 1. An LED fluorescent lamp using far-infrared radiation without a heat sink , the LED fluorescent lamp comprising:{'b': 10', '11', '12', '12', '13, 'a tube () formed at both sides of an inner peripheral surface thereof with a guide groove () extending in a longitudinal direction, formed at a lower side thereof with a fitting groove (), and formed on an outer peripheral surface thereof, which is opposite to a position of the fitting groove (), with a transmittance part () which is transparent or translucent;'}{'b': 20', '21', '22', '23', '24', '25', '21', '11', '21', '10', '22', '21', '21', '13', '21', '23', '23', '23', '23', '22', '21', '21', '23', '22', '21', '23', '23', '23', '22', '22', '24', '21', '23', '22', '25', '24', '21', '21', '21', '21', '25', '25', '23', '25, 'i': a', 'a', 'b', 'a', 'a', 'a', 'b', 'a', 'b', 'b', 'a', 'a, 'a PCB () including a base part (), a plurality of LEDs (), an upper copper plate circuit layer (), an outer circuit part (), and a lower copper plate circuit layer (), wherein the base part () is formed of a synthetic resin material and has both sides inserted into the guide groove () such that the base part () is installed in the tube (), the plurality of LEDs () are mounted on one side surface () of the base part () facing the transmittance part () in a longitudinal direction of the base part () ...
