The present invention relates to an LED lighting device including a highly-efficient power supply, and more particularly, to an LED lighting device including a highly-efficient power supply having high power efficiency even in a low power LED lighting device by charging a power supply condenser, which supplies power to a controller by using surplus voltage, to perform recycling, when the surplus voltage occurs, which is a remaining surplus voltage after a rectified voltage supplied to an LED, i.e. a load, is used in the load according to a design value. |
