To provide a base set for light-emitting diode lamps, a socket set for the light-emitting diode lamps, and a lamp fixture using them, which can basically prevent problems including life shortening caused by flow of wrong current to the light-emitting diode lamp, operation error and fire hazard etc., and capable of epoch-makingly saving time and cost for replacing an existing lamp fixture for a fluorescent lamp by a light-emitting diode lamp.
The base set for the light-emitting diode lamps includes a first base for the light-emitting diode lamps equipped with a first cap covering one end of a light-emitting diode lamp tube and two pieces of first pins projected towards outside the one end of the tube from the first cap, and a second base for the light emitting diode lamps equipped with a second cap covering the other end of the light-emitting diode lamp tube and two pieces of second pins projected towards outside of the other end of the tube from the second cap. One or two out of the two first pins and the two second pins are of non-conductive nature, and the rest are of conductive nature.
