PROBLEM TO BE SOLVED: To thin sockets, and thin a luminaire thereby by providing the sockets in which annular lamps are installed, and arranging plural electric wire inserting ports in the almost parallel direction to an installing surface in the almost tangent direction of a lamp cylinder in the sockets. SOLUTION: Sockets 5A and 5B respectively corresponding to respective annular lamps 3A and 3B are installed in an under surface position of a luminaire main body 1 symmetric to positions of respective lamp holding parts 4A and 4B. A part of the sockets 5A and 5B containing a pin inserting part 6 and a lamp support spring respectively arranged in the sockets 5A and 5B, is exposed under a reflecting plate 2 from an opening 8 of the reflecting plate 2. In a socket body, an electric wire inserting port is opened in one side surface of the body 11 so that a connecting electric wire 14 can be pulled out in the lamp circumferential direction to one side surface orthogonal to the axial direction of a lamp tube body. The socket 5A and 5B are fixed to the main body 1 by screw-fitting a socket installing screw to an installing hole of the main body 1 through an inserting hole and an inserting hole bored in the center of the lamp support spring 21. |
