PURPOSE:To enhance assembling property, reduce the number of parts items dispense with a working device, and reduce the cost of a lighting system by operating a movable socket base engaged with a mounting base within a rotation regulating range, and fitting and installing a fixed socket base to the mounting base. CONSTITUTION:Prior to the installation of a reflecting plate 7, the inward rotation in the longitudinal direction X of the mounting base 1 of a movable socket base 4 is regulated by the side wall 6b of a fixed socket base 6. When the reflecting plate 7 is approached and moved to install it to the mounting base 2, the socket base 4 is rotated in the outward direction X of the mounting base 2. This rotation is also regulated by the side wall 2b of the mounting base 2, and the inclined surface of the socket base 4 is made parallel to the inclined surface of the reflecting plate 7. |
