Beschreibung
Zusammenfassung:	Provided is an LED lighting apparatus with an improved heat radiation property, which is capable of effectively radiating heat generated therein. The LED lighting apparatus may include: a light source unit comprising a plurality of LED groups each having one or more LEDs; and a driving unit configured to provide a current path corresponding to light emission of the light source unit. The light source unit and the driving unit may be arranged on the same substrate so as to be separated from each other. Among the plurality of LED groups, the LED group having the largest heat value may be arranged farthest away from the driving unit, compared to the other LED groups. Through the above-described arrangement, the heat radiation property of the LED lighting apparatus can be improved.
