<P>PROBLEM TO BE SOLVED: To reduce power consumption of a fluorescent tube type LED lamp and an LED lighting device. <P>SOLUTION: A DC bus voltage of an inverter circuit 11 varies according to variation of a load. An LED module 12 is an LED lamp that is mounted to the inverter circuit 11 so that it can be exchanged with a fluorescent tube. An LED circuit 23 includes one or more light emitting diodes. An input terminal 20 is connected to the inverter circuit 11, and inputs power to be inputted to the LED circuit 23 from the inverter circuit 11. A rectifier circuit 22 rectifies a high frequency voltage outputted by the inverter circuit 11. An inductor 24 is inserted between the input terminal 20 and the LED circuit 23, for example, between the output of the rectifier circuit 22 and the LED circuit 23. <P>COPYRIGHT: (C)2013,JPO&INPIT |
