<p>The present invention relates to an LED fluorescent lamp which is compatible with various kinds of stabilizers formed in a fluorescent lamp. In an LED fluorescent lamp which converts the AC power of the stabilizer into DC power and provides it to an LED, the present invention includes an input circuit part which comprises a bridge rectification circuit and a full-wave rectifier in an input terminal; a capacitor dropper constant current circuit part which performs the continuous use of an LED when a fuse is molten by an overcurrent caused by L value reduction in the end of the lifespan of a magnetic stabilizer; an SCR phase control part which controls power in a rectification post condition in using the magnetic stabilizer or implements an electronic switch by using an SCR starting voltage; an overvoltage restraining circuit part which restrains an overvoltage applied to the SCR phase control part when output is opened between the input circuit part and the SCR phase control part; and a smoothing circuit part which is connected to the SCR phase control part and is directly connected to the LED.</p> |
