PURPOSE: A light emitting diode lamp is provided to improve the efficiency of a heat radiation operation due to a convection current by forming an air current based on temperature difference around a light emitting diode. CONSTITUTION: A heat sink(20) is located on one side of a base. A light emitting diode array(30) is combined to the inside of the heat sink. A reflective plate is located on the lateral side of the light emitting diode array. A transparent cover is arranged on the front side of the reflective plate and the light emitting diode. The heat sink includes a combination unit(21) and a heat radiation unit(22). The heat radiation unit forms a heat radiation path. |
