PURPOSE: An LED PCB and LED lamp unit for preventing freezing and bursting are provided to prevent an LED driver from being damaged by protecting a PCB through the heat of a hot wire in a hard winter. CONSTITUTION: One or more LEDs(110) are formed in one side of a PCB(100). A hot wire(120) is printed on the other side of the PCB. A main PCB includes one or more LEDs on the upper side thereof. A thermal conductive insulation layer is laminated on the lower side of the main PCB. A sub PCB is laminated on the lower side of the thermal conductive insulation layer. |
