The present invention relates to an LED lighting module using AC power, wherein an AC-driven LED lighting is implemented by a simplified rectifier circuit and by adjusting the number of LED elements, without using a dedicated circuit configuration such as SMPS or the like, and the LED modules are arranged in a way to enable a multiplicity of unit modules to be driven with a single power supply. Therefore, in application of such LED modules as indoor and outdoor advertising lights, the simplified rectification structure makes it possible to attain reduced manufacturing costs and smaller-size products and to save more energy at the same time, and the supply of a constant current to the LED lighting module all the time helps the module to be driven more stably. To this end, an LED lighting module using AC power of the present invention comprises: a power supply which receives AC power from outside for use as a drive source for a device; unit modules, with each unit module consisting of at least two LED sets connected together and each LED set consisting of one LED element or plural interconnected LED elements driven by an input power from the power supply; and rectifier circuits, each being separately installed in first and last unit modules to which the power is input, for rectifying AC power which is input through the power supply when a multiplicity of unit modules form a loop, thereby allowing the AC power to serve as a drive power for the LED elements. |
