PURPOSE: A high power LED lamp for the fire prevention having a convection air hole heat exchanger is provided to comprise a heat dissipation unit, thereby preventing the degradation of the heat dissipation efficiency. CONSTITUTION: A control unit (112) controls the output of an LED module (120). A heat pipe (200) is contacted with the rear side of a PCB substrate (110). A heat dissipation unit (300) comprises a heat dissipation unit body (310), an outside blade (320), an inside blade, and an air injection hole. A cap (350) is installed at the heat dissipation unit body. A switch (370) is connected to the control unit. |
