The present invention relates to an LED lamp which includes a heat sink to discharge heat from an LED device. The LED lamp according to the present invention includes: a printed circuit board which includes a plurality of LED devices which are mounted on one side thereof with a preset pattern; and the heat sink which is arranged on the rear side of the printed circuit board and discharges the heat from the LED device. The heat sink includes a plurality of heat radiation fins which are arranged on the rear side of the printed circuit board to at least partially overlap the LED devices which are arranged on one side of the printed circuit board with the preset pattern by interposing the printed circuit board; and a heat radiation support unit which supports the heat radiation fins. According to this configuration, the production costs of the heat sink are reduced by minimizing the number of heat radiation fins. The weight of the LED lamp is reduced by reducing the weight of the heat sink. |
