<P>PROBLEM TO BE SOLVED: To provide an LED fluorescent lamp capable of being mounted on an existing fluorescent lamp fixture in whichever direction without using an AC/DC converter. <P>SOLUTION: The LED fluorescent lamp provided with first terminal pairs 2, 2a and second terminal pairs 3, 3a at either end of a long cylindrical case 1, incorporating a light-emitting unit 4 equipped with a plurality of LEDs and various circuits, with first terminal pairs 2, 2a at one end connected to two input output terminals of a first bridge diode 5 and with second terminal pairs 3, 3a of the other end connected to two input output terminals of a second bridge diode 5a. When the LED fluorescent lamp having an anode side of the light-emitting unit 4 connected to a cathode terminal each of first and second bridge diodes 5, 5a and having a cathode side of the same 4 connected to an anode terminal each of the first and second bridge diodes 5, 5a, respectively, is mounted on the existing fluorescent lamp fixture, AC current is automatically converted to DC current, and as a result, the DC current enables electricity to be made to pass to the light-emitting unit. <P>COPYRIGHT: (C)2012,JPO&INPIT |
