PURPOSE: An LED lighting apparatus with an excellent heat dissipation function is provided to allow a working fluid to flow smoothly since an evaporation part is placed on a lower position than a condensation part by vertically connecting a heat pipe to a substrate. CONSTITUTION: An inserting hole is formed on an upper center portion of a case. A heat pipe(300) is installed to be vertical to a substrate passing through the inside of the case. A heat dissipation member(400) is connected to an upper portion of the heat pipe exposed to the outside of the case. The heat dissipation member includes a cylindrical body(420) in which a connection hole(440) is formed. A plurality of heat radiation fins(410) is connected to the external circumference of the cylindrical body radially. |
