<p>In the present invention, disclosed is an LED lamp capable of improving a heat dissipation function by using a mixture material of Mg and Al for a manufacture and improving a heat radiation unit to have a structure with a base, a first heat radiation wing, an air return path, an air flow path, a second heat radiation wing, a heat sink, and an air stay space. The LED lamp according to the present invention includes improves the heat dissipation function by definitively exchanging heat with the heat radiation unit through the air which stays inside for a long time and increasing a contact time and a contact area between the air and the heat radiation unit by delaying or spreading the flow of the air inputted from the outside by improving the structure of the heat radiation unit.</p> |
