LED LAMP USING OVER VOLTAGE PROTECTION CIRCUIT

摘要

Disclosed is an LED lamp using an overvoltage protection circuit, in which a switching circuit is disposed between a first rectification circuit and an LED circuit, the overvoltage protection circuit is disposed at the first rectification circuit and the LED circuit in parallel so as to prevent an electric shock accident caused by a physical contact and damage to a lamp caused by overvoltage. The disclosed LED lamp using an overvoltage protection circuit comprises: a first input base; a first rectification circuit; an LED circuit; a second rectification circuit; a second input base; a switching circuit mounted on a line connecting the first rectification circuit and the LED circuit; and an overvoltage protection circuit having one end thereof connected to a line which connects the first rectification circuit and the switching circuit, and having the other end thereof connected to the line which connects the first rectification circuit and the LED circuit.
