PROBLEM TO BE SOLVED: To provide a luminaire which can change a light irradiation direction to an arbitrary direction and can securely be fixed at a necessary rotational position and in which a stably usable long-life LED light emission body is built.SOLUTION: A straight tube type LED lamp includes a first base member 8 joined to an end of a light emission part body 2 and a second base member 9 having a metal terminal 23 inserted into the socket of a luminaire, and the first base member 8 includes energizing means 12 of energizing the second base member 9 in a fitting insertion direction. The first base member 8 and second base member 9 are engaged with and disengaged from each other by moving straight by a predetermined distance parallel with an axis of rotation, and the first base member 8 is rotatable when the second base member 9 is moved to extend the length of the straight tube type LED lamp. |
