PURPOSE: A lighting device is provided to quickly transfer heat to a heat emitting part by a heat conductive part for heat exchange, thereby increasing the efficiency of emitting heat. CONSTITUTION: A lighting device(100) comprises a heat emitting part(10), a heat conductive part(20), a substrate(30), at least one solid light emitting device(40), and a sow block(50). The heat emitting part includes first and second ends which face each other. The heat conductive part is installed in the first end of the heat emitting part. The substrate is installed on the heat conductive part. At least one solid light emitting device is installed on the substrate and electrically connected to a circuit on the substrate. The sow block is installed on the second end of the heat emitting part and electrically connected to the substrate. |
