PURPOSE: An LED(Light Emitting Diode) lamp is provided to prevent the malfunction due to the heat and the reduction of lifespan by compulsively cooling a circuit board through a fan motor. CONSTITUTION: A diaphragm is horizontally arranged inside a lid part(10). A case part(20) is combined under the lid part. An air injection hole and an air outlet hole are formed in both sides of the case part, respectively. The circuit board is arranged inside the case part. A plurality of LEDs are installed on the circuit board. A fan motor is fixed to the bottom surface of the diaphragm in order to induce the air to the circuit board. A power supply part includes a solar cell array and a storage battery. A transparent cover is combined in the bottom of the case part. |
