A cooling structure of a street lamp using an LED(Light Emitted Diode) is provided to improve the durability of the street lamp and to prevent an error of the street lamp by rapidly cooling a heat of a high temperature generated from the street lamp. A cooling structure of a street lamp using an LED includes a heat radiation case(5), a printed circuit board(1), at least one light emitting diode(4), a heat transfer unit(501), a reflective unit(601), and a heat radiation pin(602). The heat radiation case has an installation unit. The printed circuit board is formed on the inside of the installation unit. The light emitting diode is formed on a lower part of the printed circuit board. The heat transfer unit radiates the heat generated from the light emitting diode to an upper part of the heat radiation case. A penetration unit is formed on the printed circuit board of an area coupled with the light emitting diode. A heat transfer member(2) is filled in the inside of the penetration unit. A plurality of heat transfer plates(3) are formed on an upper plane of the penetration unit. A plurality of heat transfer parts couple the heat transfer plate to the upper plane of the heat transfer case. The reflective unit is formed closely to the light emitting diode on a bottom plane of the heat radiation case. The reflective unit reflects the light emitted from the light emitting diode. A reflective plate(6) has the reflective unit and the heat radiation pin. The reflective unit is formed on the reflective plate. The heat radiation pin is formed between the reflective units. |
