<p>The present invention relates to a power supply device for driving an LED module and an LED lighting device including the same and, more particularly, to a power supply device and an LED lighting device including the same capable of maintaining a current flowing through each LED module and independently operating one or more LED modules by controlling one or more LED module power supplies by using a micro controller as a control device. The power supply device for driving an LED module includes: an LED module power supply (10) composed of one or more DC-DC voltage converting devices generating a high output voltage converting an input DC voltage into an LED operating voltage; a control device (20) composed a micro controller for controlling the LED module power supply; a control device power supply (30) composed of a DC-DC power converting device generating low output voltage and a control device driving power supply converting the input DC voltage into a control device voltage; and an input DC power supply (40) composed of an AC-DC voltage converting device converting commercial AC power into the input DC voltage in order to supply the input DC voltage. The LED lighting device includes one of the power supply devices (1,2,3) and one or more LED modules (50) operated with the power supply devices. The LED modules are connected with a plurality of LEDs in series.</p> |
