PURPOSE: A light emitting diode (LED) array and an LED lighting device thereof are provided to be stably operated by using an alternating current (AC) power source. CONSTITUTION: An LED array (310) comprises a first LED package (320a), a second LED package (320b), and a third LED package (320c). The first LED package comprises a first LED chip (330a-1), a second LED chip (330a-2), and a third LED chip (330a-3) in the first low. The second LED package comprises a first LED chip (330b-1), a second LED chip (330b-2), a third LED chip (330b-3) in the second low. The third LED package comprises a first LED chip (330c-1), a second LED chip (330c-2), and a third LED chip (330c-3) in the third low. The LED array forms an LED group according to a control unit by connecting each LED chip in serial. [Reference numerals] (100) Power unit; (300) Control unit |
