<P>PROBLEM TO BE SOLVED: To provide a lamp socket and a lighting fixture using the same capable of loading a specific straight-tube LED lamp and preventing an existing straight-tube fluorescent lamp from being mistakenly loaded. <P>SOLUTION: The lamp socket is provided with a lamp holding part 17, and a socket body 1 storing the lamp holding part 17. The socket body 1 is equipped with a rotating shaft part 2c for holding the lamp holding part 17 in free rotation. The lamp holding part 17 is equipped with a rotator 4 retained at the rotating shaft part 2c in free rotation, and two conductive plates 5 each capable of separately elastically contacting a pin body of each lamp pin. The rotator 4 is equipped with a disc-shaped rotator body 4a, and a bearing part 4b outwardly fitted to the rotating shaft part 2c. At a peripheral part of the rotating shaft part 4a, positioning parts 4g made of two-piece pair of protrusions 4f for regulating movement of key parts of the lamp pins are provided in separation, and, between the both positioning parts 4g, a wall part 4e is provided for preventing contact of each conductive plate 5 and the pin body of each lamp pin in resistance against spring force of each conductive plate 5. <P>COPYRIGHT: (C)2012,JPO&INPIT |
