Zusammenfassung:PROBLEM TO BE SOLVED: To provide an LED fluorescent lamp that keeps turned on unless all LEDs in use are cut off at a time even if a large number of LEDs is used.SOLUTION: In an LED fluorescent lamp, LED sockets are juxtaposed on a substrate having an LED lighting circuit in the inside of a semi-transparent synthetic resin base, and LEDs are made possible to be replaced by being inserted and fitted into the LED sockets. Even if one LED is cut off, the other LEDs are not cut off and then the cut LEDs are replaced by making the LED lighting circuit a parallel circuit on the substrate.
