Abstract
A high-voltage linear drive and memory dimming LED lighting device is disclosed. The lighting device includes a high voltage linear constant current circuit, a control IC, a first LED string and a second LED string. The control IC is electrically connected to the high voltage linear constant current circuit, and the control IC is directly driven by receiving high voltage signals. Wherein, the control IC includes a voltage regulator module, a switching module and a memory module. The voltage regulator module is electrically connected to the high voltage linear constant current circuit; the switching module is electrically connected to the voltage regulator module and includes at least two electronic switches; and the memory module is electrically connected to the switching module.
