Abstract
A lighting device includes a rectifying circuit, first filtering capacitor, resistor element, transient current suppressing circuit and voltage divider circuit. The two ends of the first filtering capacitor are connected to a first node and second node respectively. The two ends of the resistor element are connected to the second node and third node respectively. The transient current suppressing circuit includes a switch and first adjusting capacitor. The three ends of the switch are connected to a fourth node, second node and third node respectively. The two ends of the first adjusting capacitor are connected to the second node and fourth node respectively. The two ends of the voltage divider circuit are connected to the first node and fourth node respectively. The first node, third node and second node are connected to the first and second output ends of the rectifying circuit and grounding point respectively.
