PURPOSE: An LED light device is provided to increase the light emitting efficiency and lifetime of LED packages. CONSTITUTION: At least one LED package(100) is bonded with each metal plate(30). A power generator(202) operates the LED packages. Metal plates are radially arranged on the power generator to form a free convection path of heat. The metal plates do not have resin layers. The light emitting surface of the LED packages faces downward to bend the metal plates. |
