LED STREETLIGHT WITH HEAT RADIATING STRUCTURE

摘要

PURPOSE: An LED(Light Emitting Diode) streetlight is provided to improve heat radiation efficiency by transmitting the heat from an LED to a case regardless of the shape of the case. CONSTITUTION: A thermal conductor(300) includes a heat sink, a vertical heat sink, and a plurality of heat radiation fins. The vertical heat sink is vertically arranged on the upper side of the heat sink. The heat radiation fin is formed on both sides of the vertical heat sink or the upper side of the heat sink. The heat radiation fin has a vertical cross section with a branch shape. The bottom of the heat sink is contacted with the upper side of a printed circuit board(400). The upper side of the vertical heat sink is contacted with the lower side of an upper case(100). A reflector(500) has a first penetration hole and a second penetration hole.
