PURPOSE: A street light equipped with a power LED(Light Emitting Diode) is provided to improve the directivity of power LED light by a cover portion having a check shape pattern, thereby uniformly radiating the light. CONSTITUTION: In the inside of a body housing(100), a space part opened to a lower side is formed. A socket(110) is installed in the central part of the space part. A light source part(200) is connected to the socket. The light source part radiates light with a plurality of power LEDs by an applied power source. A heat radiating part(300) radiates the heat of the light source part in the upper part of the body housing. A cover part(400) covers the opened space part of the body housing in which the light source part is installed. In the substrate of a hemisphere shape, a plurality of copper patterns and the power LED are installed. The substrate is projected to one side in order to form the space part on the inside. |
