It is the task of the present invention to provide an LED lighting device that is adapted for an AC voltage supply. Suggested for this is an LED lighting device 1 for an AC voltage supply 2, with several LEDs that form a whole chain 9, whereby the LEDs are divided into LED part groups 11a, b, c, whereby a supply voltage with changing amplitude is present in the LED lighting device 1, whereby several LED part groups 11a, b, c are arranged in series with each other and form an LED strand 8, 8a, b, c, and with shorting links 12a, b, c, each designed for bridging one of the LED part groups 11a, b, c in the LED strand 8, 8a, b, c, and with a control means 10, whereby the control means 10 is designed for controlling the shorting links 12a, b, c in order to place the LED strand 8, 8a, b, c in at least two switch states I, II, whereby the at least two switch states I, II differ in the through voltage of the LED strand 8, 8a, b, c.
