<p>PURPOSE: A light emitting diode(LED) lamp connection-circuit for a fluorescent lamp is provided to protect the circuit from load-short-circuiting by arranging a fuse and a thermistor between two rectifier-circuits. CONSTITUTION: Rectifier-circuits(200, 210) are located on both ends of a LED lamp connection-circuit. The rectifier-circuits rectify an alternating current to direct current power and supply the direct current power to an LED drive-circuit(240). A circuit protective unit(230) protects the LED drive-circuit by controlling the rectified direct current power. The circuit protective unit is serially connected between the rectifier-circuits and the LED drive-circuit.</p>
