Abstract
A lighting device is configured to receive a first voltage signal, and includes: a first circuit coupled to input terminals for receiving the first voltage signal, the first circuit including: rectifying diodes for rectifying the first voltage signal and supplying a second voltage signal, a first capacitor for buffering the second voltage signal, and a second capacitor coupled in parallel to one of the rectifying diodes of the first circuit; a second circuit receiving an input voltage signal, corresponding to the second voltage signal, and converting the input voltage into an output signal; and a light circuit receiving the output signal of the second circuit and including at least one light emitting diode, wherein the first circuit includes a fourth circuit in parallel to the second capacitor, the fourth circuit including at least two fourth circuit diodes and being connected by a fourth capacitor to one of the input terminals.
