PURPOSE: A lighting device is provided to improve heat radiation characteristic by installing a light guide plate aligned with a light source. CONSTITUTION: A light source mounted on a lower plate(100) is a light emitting diode. A guide side of a polygonal shape is provided in the lower plate. The guide side is mounted in a circuit board(200). A light emitting diode is mounted in the circuit board. The light guide plate is installed in interior of the guide side. The light from the light emitting diode is transmitted to the light guide plate. A light source is projected to interior of the light guide plate to perform an illumination function. |
