PURPOSE: To keep a Iuminaire from decreasing in merchandise properties in terms of its appearance and from increasing in size by setting above the lower end of a fluorescent lamp a boundary formed by a reflector specifying the position of the end of an opening and by a louver structure specifying the position of an end plate at the other side. CONSTITUTION: A reflector 6 is secured to the mounting plate 1d of a luminaire main body 1 with a face screw 7. With the hooks 8 of a louver structure 3 inserted into hook holes 1e in the main body 1 to hook the louver structure 3, the structure 3 is rotated. After the operating end 9b of a clamp 9 is pushed inward against the force of a spring to keep a locking tongue from coming into contact with the main body 1, the operating end 9b is released and then engaged in a locking hole If to lock the structure 3 to the main body 1. The other side 3K of the end plate of time structure 3 is located below the lower end 2a of a fluorescent lamp 2, and the end 6a of an opening in the reflector 6 is located above the lower end 2a of the lamp 2 to serve as the boundary between the structure 3 and the reflector 6 so that when you saw from the underside along the diagonal direction, the boundary does not enter the field of view, thus making the luminaire look better. |
