Abstract
LED devices or circuits include a number of serially connected LED segments, which may additionally include parallel branches, which are switched on or off depending on an input voltage to the LED segments. As the input voltage varies, none, different portions, or all of the LEDs are lit. The input voltage to the LED segments may be an output voltage from a bridge rectifier in response to an alternate current (AC) power. The LED devices or circuits include no inductors, transformers and electrolytic capacitors.
