PROBLEM TO BE SOLVED: To provide an LED lighting device capable of forming a wiring passage on an arbitrary heat radiation fins arranged on a heat sink by using AC LED capable of being driven without SMPS or LED AC driving circuit and eliminating a central core structure conventionally arranged in the heat sink of an LED lighting device and reducing weight of the LED lighting device and improving heat radiation performance of the LED lighting device.SOLUTION: An LED lighting device includes a heat sink having a plurality of heat radiation fins, a light-emitting module located on an upper part of the heat sink, a power source connection section located at a lower part of the heat sink, a floodlight cover arranged to cover the upper part of the light-emitting module, and the wiring passage formed on the arbitrary heat radiation fin of the heat radiation fins so as to store the wiring for connecting electrically the power source connection section and the light-emitting module. The light-emitting module can emit light via the wiring stored in the wiring passage by directly supplying the AC power source. |
