The present invention relates to an LED printed circuit board for preventing damage due to cold weather and an LED lamp unit including the same. The LED printed circuit board for preventing damage due to the cold weather includes: a printed circuit board; one LED which is mounted on one side of the printed circuit board; and a heating unit which is separated from the LED on the printed circuit board and generates heat by external power. Thereby, damage to the LED and an LED driver that are the main components of the LED lamp is prevented by protecting the printed circuit board by the heating unit even though the LED lamp unit is used as an external lamp in cold weather. |
