Abstract:
1. An LED lighting device for AC voltage supply, the device comprising: a plurality of LEDs forming a whole chain, wherein the plurality of LEDs are divided into a plurality of LED part groups wherein a supply voltage with changing amplitude is presented in the LED lighting device; a plurality of serial switching means, wherein the LED part groups are each allocated to one of the plurality of serial switching means, wherein the associated LED part groups and serial switching means form an LED assembly, wherein the serial switching means are configured to interrupt a current flow in the associated LED part groups, and wherein two or more LED assemblies are switched in series to form an LED gap in a plurality of LED profiles; a plurality of shorting links, wherein the plurality of LED profiles are each allocated to one of the shorting links, and wherein each shorting link is configured to bridge the LED assemblies in an associated LED profile; and a control means, wherein the control means is configured to control the shorting links and the serial switching means for placing the whole chain in at least two switch states, wherein the at least two switch states differ in the through voltage of the whole chain, wherein the device comprises a plurality of the LED gaps, the plurality of the LED gaps being arranged electrically parallel with each other such that the LED assemblies of the LED gaps form the LED profiles, wherein the shorting links allocated to each LED profile are configured to bridge all LED assemblies of the LED profile.
