<P>PROBLEM TO BE SOLVED: To provide a straight tube LED lamp in which wrong installation to a lighting fixture for a fluorescent lamp hardly occurs, and a lamp socket used for the same, as well as a lighting fixture for straight tube LED lamp using these. <P>SOLUTION: The straight tube LED lamp 1 is provided with an arc tube of straight tube shape in which a light-emitting diode is housed, a power feeding base 3 installed on one end side in axial direction of the arc tube, and a grounding base 4 installed on the other end side in axial direction of the arc tube. The power feeding base 3 has two base pins 7a which are electrically connected to a power feeding contactor provided on a power feeding lamp socket. The grounding base 4 has a grounding terminal which is electrically connected to a grounding contactor provided on a grounding lamp socket. The two base pins 7a are arranged along the axial direction of the arc tube and the tip sides of the two base pins 7a project respectively at a nearly right angle to the outside direction. The shape of the grounding terminal is formed in a long and slender shape in installation direction of the grounding lamp socket when viewed from the axial direction of the arc tube. <P>COPYRIGHT: (C)2012,JPO&INPIT |
