Abstract
An LED lamp protection circuit comprising: a driving circuit, a rectifier circuit coupled with the driving circuit, an LED luminous component circuit coupled with the rectifier circuit, and an arcing protection circuit coupled between the rectifier circuit and the LED luminous component circuit. The arcing protection circuit and the LED luminous component circuit are connected in parallel. When the LED lamp works under a normal condition, the arcing protection circuit is in blocking state. When at least one circuit between the rectifier circuit and the LED luminous component circuit opens, the arcing protection circuit is turned on, the driving circuit and the arcing protection circuit form a loop circuit to extinguish arc.
