TUBE TYPE LED LAMP

摘要

PURPOSE: A tube type LED lamp is provided to supply stable lighting with high brightness by efficiently discharging heat from an electrode junction of an individual LED device. CONSTITUTION: A bridge rectifier circuit(210) rectifies inputted AC by a stabilizer. The power of the stabilizer connected to a bridge rectifier circuit is inputted via a plurality of diodes. A choke(230) removes the pulsating of a load current applied to an LED module(100). An LC circuit(240) maintains a power factor of the load over 0.98.
