PURPOSE:To eliminate risk of interference of lighting devices when a support is to be mounted and construct the support in a small size by enabling the lighting devices to move between the position enclosing mounting holes in the support and the position exposing the mounting hole. CONSTITUTION:When a support 11 is mounted on a surface, two lighting devices 41, 42 are rotated so as to open round threaded parts 15, 16, to generate the condition in which mounting holes 13, 14 in this support 11 are exposed when viewed from the front. In this condition, a holddown screw 10 inserted through the holes 13, 14 is screwed fast to the wall, and the support 11 is fixed. Then the lighting devices 41, 42 are rotated so as to close and accommodated on the support 11. The holes 13, 14 in the support 11 are concealed by the devices 41, 42 when viewed from the front. Then the support 1 and devices 41, 42 are covered appropriately, and a lamp is fitted in a lamp socket 23. Thereby the easiness and reliability in mounting of the support are enhanced, and the support can be constructed in a small size. |
