Abstract
A lighting device protection circuit includes an input module, a rectifying module, a driving module and a varistor. The input module includes a positive electrode input end and a negative electrode input end. The rectifying module has a first end, a second end, a third end and a fourth end; the first end, the second end and the third end are connected to the positive electrode input end, a first node and the negative electrode input end respectively. The first node is connected to a grounding point. The driving module has a first pin, a second pin, a third pin and a fourth pin, which are connected to the fourth end, the first node, a second node and the positive electrode of a LED module respectively. The second node is connected to the negative electrode of the LED module. The varistor is connected to the LED module in series.
