PURPOSE: An LED lamp using a natural draft is provided to discharge the heat from an LED through a vent formed in an upper cover and the vent formed in a side of a housing by a natural cooling method. CONSTITUTION: A plurality of LED elements are arranged in a bottom surface of a substrate(200). A lower cover is formed in a lower part of a housing(100). The lower cover fixes the substrate. The lower cover diffusely reflects the light from the LED element. A heat sink(300) is positioned in the upper part of the LED element and discharges the heat when the LED element emits the light. An upper cover(400) is coupled in the upper part of the housing. The upper cover prevents the rainwater from soaking through the housing. |
