PURPOSE: A radiator for an LED including a front radiator and a rear radiator is provided to improve heat radiation efficiency by discharging heat from a support rod connected to the front radiator through the rear radiator. CONSTITUTION: A front radiator(110) is installed in the front side of a printed circuit board(20). A rear radiator(120) is installed in the rear side of the printed circuit board. A lead(11) of an LED(10) passes through a lead through hole(112) and is inserted into a lead hole(21) on the printed circuit board. The lead of the LED is electrically connected to a pattern(22) on the rear side of the printed circuit board. An insulation bush(115) is inserted into the lead through hole to prevent the short of the lead.
